Got a silly question,

I have a 1975 coupe with TT II's, 17 in. on the car but I want to also setup my rally wheels (15 in.) with new tires. I want to run the BFG, TA's,

What size tires can I run on this car that are a little larger than the factory size tires, I believe they were G70-15's

Thanks

 

I've run 225s and 235s with no problems. If memory serves, the OEM size equated to 205s.
