2007 Nbs Tire/wheel Fitment

[kxlexus]

Hello everyone. Just found this forum a couple days ago. Lots of info on here. I have been looking back at a lot of post and have a question I am sure has been answered many times but I have yet to find it.

Any way, I have a 2007 Sierra NBS 1500 4X4 extended cab. I want to dress it up some with some new tires and wheels. I want to know what the largest tires and widest wheels i can fit on my truck with and without a leveling kit. I will probably go with a 20" wheel but possibly a 22" wheel. Don't need an aggressive mud tire. I want a tire that last a long time and is quiet on the highway as this is my daily driver.

Thanks,

Steve
