I've been reading since I got the truck last week and have searched but can't seem to find an answer. I have an 09' 4x2 Screw and would like to put a bigger set of tires on it. With a 2" leveling kit and 18's what is the biggest tire that I can run. I have seen that 305/65/18 fit the 4x4 but what about the 2x4s. Pic would be great if you have them.

 

The 4x2's sit lower than the 4x4's. Info is limited on the 09's, but the fitment appears to be similar to the 04-08 trucks. As always, a lot depends on the wheel you use. I think a 305/65-18 (34x12.50) is a little too large. I'd suggest a 285/65-18 (33x11.50) or 305/60-18 (33x12.50).

 

Thanks that is what I was thinking just wanted to hear it from another source.
