i have a 2001 chevy silverado 4x4. it's a 5 spd V-6. really great truck. i want to dress it up a little and was wondering how big of a wheel and tire i can get? i want them to stick out from the wheel well about an inch just to give it a beefier look. any help? sizes i need? i want the rim to be black and simple just regular holes going around the rim. it will need to have 6 bolts. any help please! thanks guys!
