I was wondering if its possible to mount GMC jimmy tires onto my 94 9c1. The size for my car is p235/70R15, where as the jimmy is p235/75R15. I would love to have the extra tread for winter! What is the difference between 70 and 75?

About 3/4" of height. It will throw your speedo off, but then if you're already running 235s, your speedo is already off.

FYI: you may get the inside of the front tires rub on the front swaybar or frame when turning the wheel full left or right with the p235/75R15 tire on the car.
