Need Help with tires

[08RedChevy]

New to the forum, just found it. Great site with real good input. I just bought a new 08 4door 4x4 and i'm getting ready to install the 2 in. leveling kit and would like to find out whats the biggest size tire i can run after doing the mod. I have the factory 20 inch wheels but want to replace them with 20inch Mazzi Hulk's. My tires now are more street and i would like to run something work offroad type.
Thanks for any help.

the leveing kit shoud tell you what the biggest size is.

is the truck a 1500?

Welcome to the site. I'm sure some of the NBS trucks will give you the info' you need, as there are several on the site that have already done the leveling kit. Good luck!

you should be able to run a 33/12" tire on your truck. that is about a 285/60R20, or if you want a little wider would be a 305/55R20

Yes its a 1500, Thanks for the help.
