    Default Biggest Tire on 2001 GMC Sierra SLE

    What is the biggest tire I can put on my stock 2001 GMC Sierra SLE Ex Cab. I found an awesome deal for a 15' rim with 32/11.5/15 tires. Will they fit?

    Depending on the backspacing of the rim they will fit, you might have to tighten up the torrion bars a bit to prevent the tire from rubbing. Is yout truck 4 wheel drive?

    2 Wheel Drive. Should i just invest in a leveling kit that raises the front and the rear? 4 rims with brand new tires, for 400. They look amazing

    If I remember right 15's wont fit because they will hit on the caliper. I had a 2000 z71 and thats what I was told. 16 was minimum. I know my current truck with 16's if they dont put the stick on weights in the right spot they will hit on the caliper as well.

    Yeah man you will need a 2.25 inch leveling kit to fit around a 33 or raise your torsion bars either one will work with a 32 11.50 for sure will no rubbing.
