Wheels

I recently bought an '06 Silverado extended cab 1/2 ton LT3 4x4. Does anyone know the rim width on the 17in polished cast alu.wheels ? I'm wanting to pick up a set of American Racing Chambers. On Americans site it shows the 17x9 as the choice for this truck. I'm curious how much further outboard this wheel will be compared to stock, and if the 265/70R17's would be ok on this rim? I'd kind of like to not have to run fender flares if possible. Thanks

17x9 will not extrude the fender. I believe the stocks are around 7"-7.5" in width. I'm not sure if the 265 will work. I believe so, but you may need to go to a 275.
