31\'s on a stock Jimmy

I am getting ready to buy a 1991 GMC Jimmy. One of the small ones. I want to lift the truck enough to use some pretty serious mudders. It has the stock aluminum wheels on it. I wanna know what is the biggest tire I can put on this truck without the tires rubbing. I honestly would like to run a set of 31's. If anyone can help,Please do.

Re: 31\'s on a stock Jimmy

31's would be a real tight squeeze, but I have seen one S-10 Blazer with 31 in. tires on it. It was stock. Tire brands are different in there sizes. Most 31's wouldn't fit a stock S-10 or S-15 from what I have seen.
Here is a link to a hit or fit chart:
I run 235/75/15's but I bet I could run a set of 30's without much problem.
Hope this helps.

Re: 31\'s on a stock Jimmy

I've seen a few people fit 31's by cranking the torsion bars and bending the front inner fender back, but it's a tight squeeze and I really don't recommend it. A 2" body would be the way to go to fit 31's with out worries of rubbing. With 31's on stock alloys the tires will rub the sway bar at full lock, but it's not a problem.

30's on stock alloys will fit with a slight crank of the torsion bars.

Hit? Them tires rub. Rubbin's off roadin.
