Largest wheel fitment for '70 GTO
 

Guys, what is the largest wheel/ tire combo I can run on a '70 GTO with fender lip trimming?

thanks

I run 18x10.5" rear with a 294/40 tire, no rubbing at all. You can probably run a 305 tire. Back spacing is 6.25" in the rear

In the front, I am running a 18x8 wheel with 255/40 rubber, also no rubbing. However, I just ordered some wheel hoops to widen my front wheels to 9.5" wide, and will run a 275/35 tire. I expect little to no rubbing. I currently have 4.5" inch backspacing and the new hoops will make it closer to 6".


The place that it might hit first is on the sway bar. If you run a DSE or a Ridetech bar, they seem to fit tighter to the frame, so that may not be an issue.

Hope that helps.
