tire fitment
 

I am new to your site but i am wondering if anyone has tried to fit 34-10.5-17 LTB swmpers on a '99 4x4 body style F150? i like the look of a truck when the wheels fill up the wheel wells... i know that 285 bfgs fit also but what about 305s or 315s? any help would be greatly appreciated....

315's wont fit without some sort of lift, theyll rub pretty good (although, Ive seen one or two guys do it somehow, but its looks way too stuffed IMO).

305's will fit on the stock wheels with some trimming of the plastic valence or cranking the t-bars, but with wider aftermarket wheels you have to crank the t-bars and do some trimming.

thanks for the info....is the Xcal 2 a good tuner? i have not heard about them until i got on this site.....

Im very happy with it. I havent used any other tuners so I cant really compare, but I think its the best mod a stock truck can do...it does ALOT more than any intake, exhaust, efan setup, can do.
You can read more info on it in the chips section.
