Im a newbie, I have an 09 silverado 4x4 ex. cab, reg bed.
I currently have 17" rims with 265/70/17
I would like to run 285/70/17 but the tire store says they will rub
suspension and possibly wheel well.

Is this true? Any advise Please?

 

i think you have to buy a 2" coil spacer for up front to run the 285's with no trouble
