2009 Silverado Z71 ext cab 4x4 with Factory 18"

[arz71]

I am fixing to put either a 2.25" or 2.0" leveling kit on the front end and get it aligned.

 

I have the factory 18" wheels with the stock Bridgestone tires.

 

The big question is what would be the best tire the BFG All Terrain or the Nitto Terra Grappler both would be 10 ply.

 

Then if I am understanding correctly running the 275 would be the biggest tire I could go with the factory 18" wheel correct?

 

From what I am reading the 17" factory wheels allow the 285 to be installed due to the offset right?

275/70(tallest) or 285/65, or maybe a 305/60(widest) with a little trimming. If I'm not mistaken all the factory wheels are the same offset, +31 mm

^^ This. All three sizes will work with a leveling kit. Also, I'm a huge fan of BFG's.
