65' Max Tire Size for 15's

Hello, new member here and I have a question, what is the maximum tire size using a 15x7 wheel on the front, and a 15x8 wheel on the back? Also, I would like to know back-spacing as well. Again, for a stock 65 GTO. (Disc brakes in the front, drums in the back)

Thanks! - Randy

Hi Randy,

I have a '65 with 15" rims, in the front I have 225/60/15's and in the rear I am running 235/60/15's. With this set-up I have no rubbing or scrapping while turning or going over bumps. Originally I had 235/60/15's up front as well, but they rubbed quite a bit. My rims are American Racing, CP200, they have been on the car since 2004, and now the chrome is starting to fade quite a bit. I am presently looking for some Hurst Hustlers, 15" but that is turning out to be very fruitless.

Attached is a pic from last summer season.
