General Information

Wheels

Date Coding

1. Date coded set of steelies ‘68-’70 in good shape are hard to come by and are sought after. If pitted bad they are not.
   

2. 
   

3. Mopar had two manufacturers. Kelsey hayes and Motor Wheel. Both had different formats by the stem and both where available depending on plant. The date code reference is by the valve stem to the L and R of it.1970 and above they had a PN stamping as well. They have also been reversed stamp and mix matched.
   

Kelsey-Hayes

1. Typically when your are facing the rim and the valve stem at 6 o'clock, to the left pf the stem is the year and month and to the right is the day. If done properly it should read:
   

2.     K8 11 (valve stem) 1 facing the rim with stem at 6 o’clock.
   

3. 
   

4. Another reads:
   

5.     K23 5 left side of the valve stem then on the right of the stem is 13 675.
   

6. The 2 is for shift, 3 for ‘73. If there is just 3 dimples to hold the hubcaps then I would say ‘63.
   

Motor Wheel

1. A Motor Wheel stamped with M37 8 29 has the pentastar and part number 3699117 on it.
   

Wheels Adapters

1. On a 7 1/4 rear - end, do spacers serve also as adapters to a 4.5" bolt pattern? 
   

2. 
   

3. My understanding is that the backspace is the distance / measurement from the wheel mounting surface to the inside rim of the wheel. So what I did is lay a rim (without the tire) down flat and laid a level across the rim. I then measured from the lug hole straight up to the level and came up with the same 3 1/4 measurement. Sooooo, that's the backspace? Then, the offset is where the mounting surface is in relation to the the center of the wheel. So, if in this case you have a 6 1/2 inch wheel the mounting surface is centered and you have zero offset. I think I measured the wheel at 5 1/2"wide, so I would have a 1" offset? Somebody please tell me if this is right or wrong.
   

4. 
   

5. Aren't you really dealing with the width of the rear end plus the configuration of the wheels, to the wheel wells? I'm going to replace the rear end for a stronger one and a 4.5" bolt pattern. I read on FABO that a lot of guys were using modified Explorer rear ends. So, I went outside, got a tape measure, crawled underneath the Barracuda and measured on the inside from rim lip to rim lip. Don't remember exactly what that was. Then I crawled under my 96 Ranger and took the same measurement. The Ranger was 1" narrower!  So my Ranger rear end and wheels will fit under the Barracuda! Everything that I have read so far says that you have to narrow almost any rear end to fit under an A-body. Now I know that I can put a Ranger 8.8 rear under the 'Cuda and find rims close to the configuration of the Ranger wheels.
   

6. 
   

7. All of this is mainly because THERE ARE NO MOPAR USED PARTS IN THIS AREA----PERIOD! And I don't want to drill my axles and rear drums.
   

8. 
   

9. Our cars had wheels with 3 1/4" backspace. Most modern wheels have 4 3/4" backspace. My opinion is that if you change wheels it's good to keep your offset.
   

10. Ricardo Esperon Graham
    

11. 
    

12. I've been looking at various wheels on Craigslist in anticipation of changing my bolt pattern to 4.5". My question is regarding the compatibility of the new wheels on the old hubs. It doesn't look like the front hub has room to fit in the wheel. 
    

13. Jim Conner - ’68 Cuda
    

14. 
    

15. I agree with you concerning wheel backspace and offset. But in the case of a 5,5 in wheel with 3 1/4in backspace, the offset would be 1/2 in. I have the original 8 1/4 rear end (my car really) with small bolt pattern (4 in). My spacers were designed to mount 100mm bolt pattern wheels. Now there is no space to drill 5 holes on a 4 1/2" bolt pattern because the holes are evenly spaced. My 16 in wheels centers were modified and have 2 different bolt patterns, 100mm and 4 1/2" so they can be mounted on my adapters and on cars with 4 1/2" bolt pattern. The job is well done but I'm not very confident to use that configuration at high speed.
    

16. Ricardo Esperon Graham
    

17. 
    

18. I see what you are saying. A 5 1/2" wide wheel has center at 2 3/4 " and the difference between backspace (3 1/4") and center (2 3/4") is 1/2". OK - I got that, now. The Canyon wheels have 5.5" backspacing. Looks to me that if you have that much backspacing, you could possibly go up to a B-body rear end. That's 3.25" vs. 5.5" backspacing. Difference of 2.25". Theoretically, you could use a rear end that's 4.5" wider. That's without factoring in the offsets. I didn't know you had to match wheels this closely. But, I've never dealt with the issue of changing to totally different rear ends.
    

19. Ricardo Esperon Graham
    

Small Bolt Pattern Wheels

1. Wheels are 5 lug by 4.0" measurements (small bolt pattern). They will fit any A-body Dodge Plymouth Chrysler car.
   

Cragars

1. Four 15”x7" Cragar S/S wheels, 5 x 4” bolt pattern (SBC), 4 1/8” backspacing, with mounted/balanced BFG Radial T/A tires, two 225/60-15 and two 235/60-15. Also have used and new 7/16-20 RH Cragar nuts, plus nice heavy custom-machined stainless steel lug nut washers, and a couple extra new center caps. The tires were a very tight fit on the rear, and I found that a 1/8” spacer between the wheel and brake drum helped a lot to avoid rubbing on the inner wheel well.
   

Upgraded Hubs

1. It is getting hard to find any five by four inch rims for these cars. You either have to go with what you have or change over to the four and a half inch bolt pattern.
   

1. As for upgrading the hubs to 4.5 I should have done that as it was a bitch finding rims for it. Finally found some nice ones at Classic Ind. and they actually were cheaper than the Cragars.
   

2. Mike Jarvie - ’68 Fastback
   

1. Upgraded to the 4-1/2” lug pattern so I could put some cool Cragar SS wheels on it.
   

2. Stephen “Catfish” Parker - ’67 Conv.
   

3. 
   

4. Yep we are limited with the 5 on 4s. I would have changed over to the 4 1/2s if the car didn't have factory disk brakes.
   

5. Mike Jarvie - ’68 Fastback
   

13” - 19” Wheel Rims Sizes

13”

1. 13” rims came on the Valiant. Those 13" wheels make good spares that easily fit in the trunk floor cavity.
   

2. Nathan Nutthall - ’67 FB
   

14”

1. There are 14*4*4 1/2 and 14*4*5 1/2 wide. One vender called those wheels the hypo ones and will be hard to find.
   

1. 14" wheels aren't worth much because it's getting harder and harder to find 14" tires anymore.
   

1. Most Barracudas got the 14 x 4.5” rims. The 14 x 5.5” wheels are the “Formula S” upgrade wheels. So these would be an upgrade for a daily driver, and you could still run the stock wheel covers. The 5-1/2” wheels are less common, but they aren’t all that rare. You should be able to turn one up.
   

2. Max Heim - ’67 Conv.
   

15”

1. I use 225-60-15 tires on the front of my car. On the back, I like the way bigger 255-60-15 with 7 inch rims look. But I am currently using 275-60-15 on 8 inch rims.
   

2. Nathan Nuttall
   

16”

1. A fella named Shawn Johnson owns Newstalgia wheels in Chattanooga. Real standup guy! Mopar enthusiast from way back. He told me not to get 16" rims, that they were somewhat experimental and you didn't have the selection of performance tires that you had with 17" and up. So, maybe you were better off getting the larger rims.
   

2. Jim Conner - ’68 ‘Cuda
   

17”

1. I have 17” on the front and 18” on the rear. I wanted to go with 16” on both but couldn't find them.

Wheel Rims

Wheel Date Codes

1. Date coded set of steelies ‘68-70 in good shape are hard to come by and are sought after. If pitted bad they are not wanted.
   

2. 
   

3. Rims are confusing to decipher....Mopar had two manufacturers. Kelsey hayes and Motor Wheel both had different formats by the stem and both where available depending on plant. The date code reference is by the valve stem to the L and R of it..70 and above they had a PN stamping as well. They have also been reversed stamp and mix matched...
   

4. 
   

5. Typically when your are facing the rim and the valve stem at 6 o'clock to the left pf the stem is the year and month and to the right is the day. (i.e. - K8 11 (valve stem) 1 facing the rim with stem at 6 o’clock).
   

6. 
   

7. Does that mean the wheel I have stamped with M37 8 29 is a Motor wheel? It has the pentastar and part number 3699117 on it, but cant find any reference to that number anywhere.
   

8. That is correct that is motor wheels format...
   

9. 
   

10. left side of the valve stem K23 5 then on the right of the stem is 13 675. Guess I'm dense because I'm still not able to decipher them....done too much of this over the years 
    

11. 5/13/73 Kelsey Hayes…..
    

12. 
    

13. Thanks....but I can see where the 5 and the 13 come from but is the 23 for 1973? Is the 675 a part number?
    

14. 
    

15. The 2 is for shift from what I have seen...without seeing the rim face I assume it is a later time hence 3 for 73....you guys have to post pics....if there is just 3 dimples to hold the hubcaps then I would say 63.....without pics we are guessing...
    

16. 
    

17. A guy here is selling a pair of nos shocks with pn starts with 3 a superceded number that crossed with a 69 pn and is claiming the 9 is for 69 and it is NOT it is a later replacement but the date is 79....he gave pictures and a pat number....all you gave was the stamps…..

Wheel Rim Dealers

1. Newstalgia wheels is the place I bought my Cragar SSs through years ago now. They are very helpful. I'd recommend them.
   

2. Dave Dalmas - ’67 ‘Cuda
   

3. 
   

4. Classic Industries has them.
   

1. Find Rhinodart on Moparts on the Web - Main Index . He's near Chicago and has LOTS of A-body parts. Tell him I sent you.
   

2. Jim Lusk
   

Restoring Wheel Rims

1. To clean up a set of used Cragars wheels, first rinse the crap off of them, and then use WD40 / steel wool to get them as shiny as possible. They may have some surface rust and the chrome may have started pealing in some places. Finish by putting a coat of wax over them.
   

2. Jeff Ramin - ’67 Coupe
   

Wheel Studs

1. Originally the stock wheels studs were LH threads on the driver side and
   

2. RH threads on the passenger side.
   

Wheel Stud Size

1. Ideally you want a minimum of 1” diameter protruding beyond the nut. Some Formula S cars came with extra long studs from the factory. They were longer than the stock ones. The '67 ‘Cuda’s had them.
   

2. Mike Jarvie - ’68 Fastback
   

3. 
   

4. Some racing classes actually require longer studs.
   

5. 
   

6. For the rear with the long shank nuts on Cragar Superlites, 3" studs protruded just barely 1/2" farther than the nut, so that is about ideal.
   

Removing Wheel Studs

1. I would recommend NOT changing them by driving them out with a big hammer. The wheel bearings on my '67 started howling right after I did.
   

2. Jim Tesno
   

Left handed wheel studs

1. Is it worth it to retain LF threads on the left? Other than from an authenticity standpoint? Is it practical to have left hand nuts on the left? I've not heard of properly torqued wheels loosening up after all these years.
   

2. 
   

3. The LH threaded studs can be hard to find these days.
   

4. You can only buy them in sets at NAPA. The nuts are usually easy to find.
   

5. Dave Kirkley
   

6. 
   

7. I would recommend NOT changing.
   

Right handed wheel studs

1. I'd recommend replacing the LH with RH threads.

Lug Nuts

1. Advice varies on putting lug nut locks on your wheels.
   
   

2. Wait till you have to change a tire in the rain. My car is always near me, no need fir wheel locks.
   Bob Alvarez Jr
   
   

3. I did years ago. No problems.
   Kenny Flanagan
   
   

4. No point to it. No one else can use your wheels because they are pretty unique.
   Nathan Nuttall - ’67 FB
   
   

5. What Nathan said. If you have SBP, who’s gonna steal ‘em? Mopar guys don’t rip off people’s wheels.
   Max Heim - ’67 Conv.
   
   

Back Spacers

1. To get the maximum width FRONT rim in the front of your mopar WITHOUT flaring the fenders, you must run the most backspacing you can.
   

2. 
   

3. This is the max backspacing with 66-72 E/B/A body disk brakes and 73-76 A/E-body spindles/disks:
   

4.     For 15" rims 4.5" backspacing
   

5.     For 16" rims 5" backspacing
   

6.     For 17" rims 5.5" backspacing Some rims can go 5.72 backspacing and you should check outer tie
   

7.     rod and upper ball joint clearance.
   

8. autoxcuda
   

9. 
   

10. The key is the big backspace moving the tire in. As well as having at least 3 degrees negative camber and I am limited to 9" wide wheels in order to keep the tire centered properly (since I can't increase backspace anymore--any additional rim width goes outside and hits the fender). The 40 series tires is also fairly short. Tire diameter tends to be the limiting factor on an A body front fender.
    

11. 
    

12. My scrub radius is greatly improved with the nearly 6" backspace. Also my wheels are fairly light weight.
    

13. There is a picture of the car on my website, www.conemangler.com
    

1. 3.75 backspace is not a good idea for wide front tires on a Barracuda. Right now I'm modifying my steel wheels to get 4 3/8" backspace. This way I'll get the original wheel offset. This will improve handling too.
   

2. Ricardo
   

3. 
   

4. Won't a 3.75" backspace put the tire at about zero offset (assuming the wheel lips add about 1/2" to front and back faces making this 7" wheel about 8" wide overall)? Isn't that what the optimal front wheel offset is for our cars? I always thought our RWD cars liked zero offset.
   

5. Ed
   

6. 
   

7. 3.75 in backspace is not far from 0 offset on 5.5 in wheels (6,5 in wide overall). If you want to keep your original offset on 7" wheels you'll need to improve your backspace 3/4". That would be 4.5" backspace.
   

8. Ricardo
   

9. 
   

10. The center hole will need to be bigger than the car hub, but at least doesn't have to be exact since the car is lug centric (hopefully "lug-centric" is a car design criteria and not a wheel design criteria!)
    

11. Ed
    

12. 
    

13. On the Jegs website they show BS and offset for series 61 (5 on 4" circle) Rallye wheels:
    

14. 
    

15. 15x6....4" BS....+12mm offset
    

16. 15x7....4-1/4".....+6mm
    

17. 15x8....4-5/8"......+3mm
    

Hubcaps

1. Hubcaps are also called “dog dishes”.
   

2. There are simulated wire wheel hubcaps for your fish.
   

’68 Original Hubcaps

1. An optional style 14” hubcap was offered. Its not the mag style unit, but has the open lug nut holes for real chrome lug nuts and a BLUE center. Those are usually referred to as the "bolt-thru wheel covers" (no surprise). You obviously want the Plymouth version (they were also made for Dodge). Be aware that they only fit the standard 5 x 4" small bolt pattern, and that you will need the extra long chrome lug nuts -- 10 LH and 10 RH thread, unless you have changed the studs. Another detail is that there are two lengths of these lug nuts -- the common ones work with 4.5" wide wheels, but if you have 5.5" wheels, you need the extra-extra long ones, or they won't stick out of the holes. As far as I know there is only one source for these new, so if you can get them with the wheel covers, that would be good.

Wheel Covers

1. These are the high end deluxe wheel covers. This particular wheel cover was used in C bodies as well as the Barracuda models. The difference was the paint treatment. The Barracuda sport models used black out centers with silver script.

Tires

1. Tires connect the suspension to the road. Tire width and aspect ratio have a dramatic effect on the car's handling. To improve performance, use wider and low-profile tires.
   

Numbers On Your Tire's Sidewall

1. With a little explanation it's easy to understand what all of the letters and numbers mean on your tire's sidewall. The numbers are indicators of the size, type, and performance of the tire.
   
   

2. 
   
   

   

     Example:  P205/65R15
   
   

Tire Type

1. The letter "P" at the beginning of the "Tire Size" tells us the tire is a P-Metric tire, referring to tires made to certain standards within the United States, intended for Passenger vehicles. If a tire size has no letters at the beginning, this indicates a Euro metric tire. P-Metric and Euro-Metric tires may have different load capacities. The letters "LT," either at the beginning or at the end of the tire size indicate the tire was designed for light trucks. Vehicle manufacturers equip some light trucks with "LT" type tires. These tires generally require higher inflation pressures than passenger tires.
   
   

Tire Width

1. Is the width of the tire measured in millimeters from sidewall to sidewall. The first three-digit number in the tire size refers to the tire width. For instance, in a size P205/65 R15 tire, the width is 205 millimeters.
   
   

Aspect Ratio

1. Is the ratio of the height of the tire's cross-section to its width. The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P205/65 R15 tire, the 65 means that the height is equal to 65% of the tire's width. The bigger the aspect ratio, the bigger the tire's sidewall will be.
   
   

Construction

1. The letter "R" in a tire size stands for Radial, which means the layers run radially across the tire.
   
   

Wheel Diameter

1. Is the size of the wheel measured from one end to the other. It tells us the size of the wheel that the tire is intended to fit. A size P205/65 R15 tire is made for a wheel with a 15" diameter.
   
   

Tire Size Conversion Chart

1. You have probably found this page already with the accompanying chart accessed.
   

2. Steve Toth
   

3. 
   

4. That chart gives you the general idea, but you need to look at the product specs for the actual tire you are thinking of buying in order to get an accurate diameter, tread width, and section width. The specs will also give the manufacturer’s recommendation for minimum and maximum wheel width.
   

5. 
   

6. Tirerack.com let's you shop by tire size and if you click on a specific tire (it lists all the brands of tires in the size or front and rear sizes you want) it pulls up that tire. If you click on the SPECS for that tire it lists the max and min and design rim width for that particular tire. Really useful.

Tire Liabilities

1. Shops may refuse to mount a tire they sell (or a tire you bring in loose) if 
   

2. - the rim isn't within the acceptable range
   

3. - the load rating of the tire doesn't exceed the load rating of the car
   

4. - the manufactured date of the tire isn't beyond a certain number of years (Costco is more strict on this one, which is why they sent me away)
   

5. - the tire is too big or small for the car
   

6. 
   

7. I took a set of new tires I bought from tirerack to Costco to mount them and they sent me away saying the tires were too old for their policy. Big O mounted them without a word. 
   

8. 
   

9. To confirm the tires are adequate for the car, do this by taking the vehicle weight x the front % and compare that weight to the tire load rating. Do the same for the rear. I read quite a few articles and convinced myself I wasn't putting anyone's life in danger.

Tire Age

1. DOT rules are if the tire is 10 years old or older the tire store is not allowed to mount that tire on a rim. Even if it going to be used as a spare.
   

2. Darrel Stephens
   

1. Discount Tire refused to mount a tire I was using for a spare/roller because it was over 10 years old.  I think this is a real problem for folks who don’t put a lot of miles on their cars every year, but I acknowledge that old tires aren’t as safe as new tires – all else being equal.

Tire Size Recommendation

What tire sizes to pick - for any rim size

1. Rim Width  (inch)                (7.0”)            (8.0”)
   
   

2. Min. tire width (mm)         195 (7.5)       215 (8.5)
   
   

3. Ideal tire width (mm)         205 or 215/225 or 235
   
   

4. Max. tire width (mm)         225 (9)          245 (9.5)
   
   

5. recommended for ‘Cuda    225/60 (9)     255/60 (10)    Mosley
   recommended for ‘Cuda    225/60 (9)     275/60 (11)    Nutshell
   recommended for ‘Cuda    205/60 (8)     255/60 (10)
   
   

6. 
   

7. 15 x 7  225/60-15  @ 25.6" tall.  4.25 to 4.5" backspace should work, of course it would be best if 15 x 7  225/70-15 is too tall for the front, you have to be careful at 26"+. At that point the tire can catch the front edge of the wheel opening when it is turned in about 20 degrees, especially when backing up. 
   
   

8. 245 to 255 should fit in the rear without much effort. 
   
   

9. 275 is a squeeze.
   Michael Mosley - ’68 Coupe
   
   

10. 15 x 8  275x60x15 tire the biggest tire & rim that will fit without modification.That is a very large tire. Most people don't want that much tire, so I would probably recommend a
    
    

11. 15 x 8  255x60x15 tire
    
    

12. 15 x 7  235x60x15 it looks a little short.
    
    

13. 15 x 7  235x65 or
    
    

14. 15 x 7  235x70 will look taller and have more sidewall on it.

Tires Size

15”

1. It looks like 15" tires are getting as rare as 14". 15’s aren’t really performance tires but they will hold up to the occasional romp.
   

2. Daty Rogers - ’67 Conv.
   

1. On a ‘68 Cuda, you can run 15” tires. Put them on 8 in. 15s also with 4.25 backspace. Consider running B body SS springs with adjustable front spring hangers set on the lowest setting.
   

2. Dave
   

3. 
   

4. A 4.5" backspace on an 8" rim would fit better. I have 275 x 60 x 15 tires on my ‘Cuda and they fit fine on a 4.625" backspaced 8" rim. My car has no mods to the suspension or the body, but the rear springs have helpers on them that lift the back up a bit.
   

5. Nathan Nuttall - ’67 Fastback
   

6. 
   

7. Without the inner wheel wells moved you can probably do a 275.
   

8. 
   

9. If the inner wheel wells are relocated, you’ll have no rubbing with 325/50-15 on 15x10.  With a custom axle, backspacing is irrelevant.

1. A 225/60-15 should fit OK @ 25.6" tall.  4.25 to 4.5" backspace should work, of course it would be best if you can somehow test fit. Width should be OK, a 225 will fit on a 15x7.  225/70-15 is too tall for the front, you have to be careful at 26"+. At that point the tire can catch the front edge of the wheel opening when it is turned in about 20 degrees, especially when backing up.  245 to 255 should fit in the rear without much effort.  275 is a squeeze.

1. If you have too low Hedman headers, with 14” wheels, put on 205 70 14 tires. It resembles the old E 70 14's.
   

2. Ricardo Graham
   

1. Smaller diameter tires would just raise the rpm at cruise and use more fuel. My thinking was to lower the torque peak closer to cruise rpm, giving me more torque at a usable speed.
   

2. 
   

3. The original tire size in '67 was 6.95 X 14 (80% aspect ratio?). If I'm right, those tires would be pretty close to 25" diam. If your actual tires were 26", your engine would think the rear end is 3.10 : 1
   

4. Ricardo Graham
   

1. Goodrich recommends a 5” minimum width for 205/70-14. So that drops you back to a 195/70-14 on the standard rim. On 14 x 5.5” rims, a 215/70-14 tire is an easy fit — no interference anywhere. But that’s too wide for a 4.5” rim. The sizes I gave would be for modern raised white letter radials. There aren’t very many to choose from anymore in 14". You have BF Goodrich Radial TA (minimum size 205/70-14), Cooper, General, and Uniroyal. And maybe Big O has a house brand tire.

4. Back in the day I tried the same thing and the largest size that really fit were G-70s in back and F-70s in front. The G tires did fit but rubbed the fender when turned lock to lock.

10. Try BF Goodrich radials with the raised white letters. I have 215/60R14 front, and 245/60R14 rear - 25.6" diameter - on 14x7 chromed steel wheels with standard offset. I used the front end specs from Tom Condran's book. Car has about a 1/2" rake to the front, tires sit nicely in the wheel wells, no clearance issues with the front fender well lips and the stance looks good.

1. I run 215-70-14's on 14 x 4.5 rims. Yes, they bulge out some, but I wasn't going to run less tire.

Tire Dealers

1. Tire Rack is probably the biggest distributor in the US. If they don't show a size, well, that doesn't mean it doesn't exist, but it's going to be hard to ferret out. For any brand they carry, they will have every size. So it would have to be an obscure brand that aren't carried by Tire Rack.

Tire Safety

1. It is not safe to mix bias ply and radial on the same axle. And if you have a Suregrip, you need to have the same rolling diameter on each side on the rear.

Spare Tires

1. I read somewhere about a Ford space saver spare working as a spare for our Barracudas but I can't prove it. Does anyone know more about what will and won't work for a spare. I need something that will fit down in the spare tire recess and not stick up too far so the spare cover and trunk mat will lay right. Also needs to be the 4-1/2" bolt pattern and fit over disc brakes.
   

2. Steve “Catfish” Parker - ‘67 Conv.
   

3. 
   

4. I have a space-saver spare from a Chrysler LHS / Concord / Intrepid that seems to work OK.  Reasonably tall and the center hole is perfect, but lots of offset. Works OK for me, though.
   

5. Clair Davis
   

6. 
   

7. The center has to be opened up! But after that the spare fits very nicely into the recess with the cover flush with trunk floor.
   

8. Dr. Bob Breed - ’67 Cuda
   

9. 
   

10. When you find a new spare, the critical thing is trying to find the right diameter, so it's as close as possible to the road wheels, but still fits in the hole.
    

11. Max Heim - ‘67 Fastback
    

12. 
    

13. It can not be too wide of a tire. Some people (Dr Bob) use a spare tire out of a more modern car, even that may require opening the center hole a bit with a grinder to clear the bearing hub.
    

14. Phil Saran
    

15. 
    

16. P185/78-14 radial tires are too wide for the spare tire area to let the board sit flat. It is annoying when the board sits like that. The overall profile width would depend on what width rim it was on.
    

17. Ed
    

1. My best suggestion is just put a reproduction bias tire and stock rim that is the correct size back there. The chances you are going to need it are slim and even if you do, the reproduction bias will get you where you will need to go safely. 
   

2. Rob Robinson - ‘68 Fastback
   

3. 
   

4. Most of the older Ford wheels are 4.5. I have Mustang wheels on mine right now. You have to grind out the center a bit.
   

5. Jim Conner - ’68 Cuda
   

6. 
   

7. My spare is a P195-14 on a 4.5 rim. It is about 7/8 inch too tall -- I have 3/4 inch plywood spacers under the board on either side, and it almost lays flat. This tells me that a 185 would also be a bit too tall. The problem is that a 175-anything would be way too dinky. 
   

8. Max Heim - ‘67 Fastback
   

1. 13” rims came on the Valiant. Those 13" wheels make good spares that easily fit in the trunk floor cavity.

Spare Tire Parts

1. Parts associated with the spare tire are (bolt, wing nut, etc).
   

Restoring Spare Tire Parts

1. Use the wire wheel to strip the parts associated with the spare tire (bolt, wing nut, etc), followed by 2 coats of POR and a single top coat.
