    I have just picked up a 1969 Skylark Custom Convertible. The tires on it are 215/75/14. on all corners. I am wanting to stagger the size from back to front. What is the biggest size in the rear that will fit with out any cutting or mods to the car. I am going to run a 205/70 in the front and am looking to run a wider and taller tire in the rear. I was thinking abot 225/70 but would like to go bigger if possible....My car is now 2 hours away getting certified so I do not have it here with me at the moment....Here are the rims that are on it now....

    I had 235/60R14's on my 69 convertible with stock rallys. They looked ok and fit without adjustments. I had new springs/shocks though.

    Your tire choices are very limited with 14" wheels. You would be way better off going to a 15" Chrome Buick Wheel. They are reproduced, but are expensive. You might be able to buy some originals in "Parts Wanted"

    The P225/70R-14 is the closest to the G70-14 that the car could have been ordered with. I think they would fit all around with no problem.

    You want to stay as close to 26.4-26.6" tall for any wheel/tire height. Going away from that in the rear affects speedometer accuracy as well as final drive ratio.

    The P235/60R-14 is only 25.10" tall. Not only would that compromise your speedometer accuracy and rear gear, but I think it probably didn't fill the wheel well sufficiently. The stock tire height was 26.4- 26,6".

    245/60/15 fits well and 255/60/15 usually fits.

    Thanx everyone...some great info. Would 205/70/14 be a bad choice for the fronts if I were to go 225/70/14 on the rear...or would you suggest 225/70 on all four corners?

    I have 225/70/14 all corners on mine now and am happy with them; 205s would be kinda small on the front. (If//when I switch to 15s I’ll probably go 245/60/15.)

    225/70-14 on all corners is fine. The 205/70-14 is only 25.3" tall. It will look small in the wheel well IMO.

    Used 225-70 R 14 on my '64 Skylark. No problems and look right. 205 will probably look too small in my opinion.
