tire size

i just put a 3inch body lift on a 88 GMC Jimmy 4x4. i went according to the little tire fitment guides on the web that a 31 would fit. so i ordered 4 31x10.5x15 super swamper trxus mt. they fit but they rubbed the bottom of the fender panel by the door when the tires were turned left and right.
i want to know what size tire will fit without having to cut the body.
super swamper makes a 27, 29, 30 and 31. im afraid a 30 is going to be too big and 27 is about the same height as the stock bald tires!!
please help!!!
what fits???????

Re: tire size

it prolly came with 235/75r15's which are pretty much 29" tires. you could do a slight t-bar crank to get it just high enough to fit the 31's

otherwise, its an 88.....why not do minor trimming?

Re: tire size

I had a 92 S10 pickup, and ran 31"s with just cranking the torsion bars.
I know that cranking the bars is not the preferred method, but maybe you could crank yours just a bit to clear the tires.
It may also be that your tires have so much tread that they rub. I had some all terrains, and had no problems.

Re: tire size

its an S10 body and is still good. and there isnt much to trim anyway.

Re: tire size

Tread type makes all the difference here. I could fit 31" all terrain bfgs with no problems, but I wanted mud-terrain tires and ended up putting fiberglass on 'em to clear the back of the fender. Otherwise you would have to remove or bend back the metal splash guard to clear the tires. Careful, because just running with them as stock can bend the splash guard part into a nice, sharp curl!

I had a 2" body lift and could easily fit 30x9.50 BFG all-terrains with zero rubbing. So in order to put on some meatier tires with aggressive tread you might have to go with 30" or less. Of course this was on a '98, YMMV.

Re: tire size

You can beat the inner wheelwell in and cut the bottom lip of the fender off. It'll look alright. You may have to grind down the heads of the wheelhouse bolts at the back. I got my 31x10.50s to fit while on 15x7 wheels.

Unless you're running a weird offset wheel they should fit. Of course, slopped out suspension components will make them rub excessively.

Anyway, you can move the sheetmetal quite a bit with a block of wood wrapped with a chamois and a hammer. You may even be inclined to loosen up all the bolts on the fenders and move them closer to the door.
