i have a 1998 4wd xcab lariatand I am looking in to finding a good AT or MT and was wondering what the biggest size tire i can fit on the stock wheels aswell as what can fit in the wheel well

 

Welcome to the site! As a general rule on 97-03 4x4's, you can stuff 35x12.50's on them by using the OEM wheels or you can run a 33x12.50 on wider aftermarket wheels. Personally, I think 33's on 10 inch wide aftermarket wheels looks the best.

 

Thanks alot

 

And there will be no rubbing whatsoever??

 

You would need to crank the torsion bars, and probably do a little trimming, but nothing major.
Also depends on how wide of a tire you run (33x11.5 vs 33x12.5)

 

Right. You will have to trim a little plastic off the corner of the front bumper's lower valance.

 

ok so what i understand is that if i run 35s on oem they will fit with no rub but if i run 33s on a wider wheel i will need to do some triming i am about to tighten the torshion bars up this weekend (just adding if that helps you explain it to me any better) thanks a lot for everyones help

 

I just installed a set of 265/70/17 LT, E rated BF Goodrich Rugged Trails for $168 each, out the door here in Tucson at Discount Tire. They are a Boss tire!! Fills the wheel well very nicely but doesn't rub.
