i have an '03. with 18in wheels. does anyone know the largest size tire i can pull off w/o lifting the truck? thanks guys.

 

Using your factory rims? As a general rule + size no more than two.

 

255/60R18 would be my guess. Those are 1 inch larger in diameter than stock. General makes the Grabber AT2 tires in that size. I run those tires and they work well off road in everything but sticky mud.

Cheers,

Pete

 

I have been very pleased with mine, 265/65 18's in a bridgestone
