Running larger tires. help

[mattypsd]

i have 37x12.5 tires.. on 20's
the rub on my leaf springs when the wheel is turned all the way.
and the tires look to skinny.

i would like to run 40 inch tires in the future.. with a wider width..

im new to this so

what is needed to run 40 inch tires
and is it possible with the 6.5 pro comp lift because thats what i got

First if you dont turn the wheel all the way they wont rub. If you are realy concerned about it you can get some spacers to push the wheel out more so they wont hit the springs. 40's will fit with the lift you have but it will take some massaging with a grinder and sawzall and a hammer.

i was thinking wheel spacers.
and is the body work needed..
and anyone know were i can find some instructions
on how to properly do the body work

Why not just get a larger offset wheel and wider tires with the tire height you already have?

Like 37x14.5 or something simular from whoever makes such a tire? More offset will give the impression of a wider tire

wheel spacers are illegal, no one that i know of will install them or mess with the truck if they are installed. secondly, the 40's will rub really bad, not only on your leafs, but on the lower part of the bumper or valance, and possibly on the rear of the front fender. i have 37's with a 6'' on mine and if i hit a big bump and have the wheels turned the rub in the places i mentioned. i would recommend a bigger lift to accomodate the taller tires, and a more offset wheel to elliminate the rub on the leafs.
