I have a set of rally wheels that came with the car when I purchased it back in '89 that I've always wanted to put on. I finally got them out of storage and was going over the measurements. Maybe someone can give me some advice to see if this setup will work.

I have four 15" x 8" all with 4.25 Backspacing. I would like to attempt to use the tires I have on the car now:

Front - 215/65R15
Back - 275/60R15.


Car is stock height. But would also like to consider dropping it down a little in the future. I have stock disc brakes up front only.

Any suggestions would be greatly appreciated. I've read many posts showing the optimum measurements, but none seemed to match my specs. Which has me fearful that this may not work.

Thanks

7.5" wheel is max for the 215's. I'd go with a wider tire or smaller wheel in the front.

It's a '67 sorry. I was concerned about the back as well. Looks like I may be replacing the wheels. Not worth trying to make it work if it's not the proper setup.

When I ran Ralley wheels on my 67 RS I had 15x6 with 3.5 backspacing with 215/70-15 B.F. Goodrich tires for the front. On the rear I had 15x8 with 4" backspacing with 255/60-15 B.F. Goodrich TA's. The wheel bolt pattern was 5x4 3/4.

How do you know they are 15x8" with 4.25" backspacing? If you measured the overall width from outer edge to outer edge and got 8" then it's a 7" wide wheel. The width is measured from the inside edges of the wheel lips. Ironically backspacing is measured from the pad to the outside edge of the lip.

Thanks for the info. Guess I should have done my research. Looks like I need to re-qualify my question with that information. I would imagine 275's on a 7" tire is not desirable.(or possible?) Looks like I may still be in the market for new rear wheels.

I have 68 Camaro standard, stock ride height, front disks (ssbc),rear stock drum. Has American Racing wheels. Front 7" 3.75 BS w/215 65 15, rear 9" 3.75 BS w/255 60 15. Car came this way and rubbing issues in rear. Want to put ralley wheels. on. Will 15x7 front and 15x8 rear work with with current tires w/no rubbing issues. Love this car not the rubbing (keeps me from driving). Any help would be appreciated.

255 60 15 is about as wide as you want to go on a 15x8 Corvette rally for the rear. You may have rubbing if you have rear passengers and may have to roll the inner fender lip, 245 60 15"s no worries.
The front 15x7 195 or 205 or 255/60/15 front or rear or all four.
I have a 69, 68 for me on tire size is an unknown.

I run 245/60 and 255/60 on mine with 4.5 backspace. 275/60 on 4.25 backspace will need to have the wheel lip rolled. 255's might work but will be very close to rubbing
