want 33"x12.5X18 on 03 silverado
 

I just got my Silverado....
I'm wondering if I can run a 33"x12.5X18 with a 2-2.5 leveling kit..
Will the tires fit correctly?
Would they fit if i went with a 20" rim?

THANKS

The size of the rim (height) does not matter but you just have to make sure that you have the right backspacing or else you will rub on the inside. I wanna say for your truck you need a 4.5" backspacing. Can anyone else confirm that...

Now as far as fitting with out trimming the bumper a little bit I do not know. I know for the 88-98 body styles they need a little trimming.

With that amount of extra lift in the front it should be close. But height wise you will be. Its just clearance for when you turn that you have to worry about.
