Motion Tires

[tom406]

The backspacing on those Cragar 8" wheels will be your killer. I'm guessing they're 3-3/4" like Americans, and this will lead to contact with your fender lip. 15x7" rims with 4.25" or 15x8" with 4.5" of backspacing seem to be the key to fitting big rubber (255 or 275/60s and their bias equivalents). If it were mine, I'd have the Cragar's cut and rewelded to increase the backspace. Even jacked up, I don't want that tire to hit my car. If you're really pressed for time, I'd mount F70's on the 6" cragars, and paint up some 15x7" steel rims with 4.25" backspacing with the big tires (mount some slicks maybe?) to give it a weekend race ready look, and take some time to sort out your 8" Cragar/tire size/final stance decisions.

Don't go 14's on the front, staggered wheel sizes just never look right.....

Somebody take a picture and post it of this car at the reunion. It'll be nice to see what happens!

I personally like 14x6 with F-70-14 for the front but that is a personal preferance. The 15x6 on a '69 Camaro/Nova look to big. The wheels on the ralley green Camaro are 15x8 rear(reversed deep dish) and 14x6 front.
And actually many of the Motion cars used 14" on the front and 15" rear. Joel would run the factory 14" Firestones/Goodyears up front on 14x6 cragars and run 15x8 or 15x10 Cragars on the rear. This is how Mark Timken did his '70 B/M Camaro. Motion would use the factory front tire to just use them up and go to big meats out the back as any factory tire was worthless. Remember this is how it was done back then as these cars were street racers and the big and little look was what people wanted. Mismatched brand/size of tires from front to rear was the norm.
Again this is my preferance but I would run a good year F-70-14 on the front and a Pro-Trac L-60 on the rear. I think in one of the pics of a lineup of Motion '70 Camaros the fronts were Firestone wide ovals and the rears were M/T's.

Tom406, the backspacing for a 15x8 Cragar is 4 1/4. The wheels are tucked in more than a American TT.

Copo, you asked for wheel/tire opinions. You sure did get mine! That is what makes this hobby so great everybody wants a different look.

You mentioned you was putting on sidepipes and the large Motion rear wing. You are adding a lot of "bulk" to the rear of the car. Large rear tires will help counterbalance this and keep everything in proportion.
Too skinny/small of a rear tire combination will make your car look like size 13EEE shoes on roller skates.

The only trouble is that if the tires hit I don't think you will want to do the old school fix which was take a baseball bat and roll it between the tire and q-panels to roll the inner edge under. You may need to play with the spring arch to get the right clearance.

Or put on air shocks temporarily.

I do not want to roll the rear lip of the fenders as I have a fortune in bodywork and paint in this car. I may need to just put something on it for now to make the show and then finish it and sort things out for next year. I'm out of time as far as getting re-arched springs, etc. If Joel was not going to be at the show then I would be bringing a different car this year and just wait on the Motion to be finished for next year.

Once again, appreciate all the input. [img]/ubbthreads/images/graemlins/[/img]

I used to own a 71 BM Camaro that came from Motion w/Ansen Sprints. The rear wheels on my car were 15x8's. If you look in older CARS magazines there are many articles showing Motion cars with Ansen's

here is a nice wheel tire pic. It's Mr Motion putting the wheel on a 69 Z. Article says they tried goodyear blue streak and Ingelwoods L-series but dosen't give size.
