Somebody find a pic of a 07 up(NBS) stock with 285/70/17s....

dumb question time/ what size makes it a 32-or 33 inch tire as opposed to our 30-31(I would guess they are stock)? And will they fit on a stock 17 inch rim. My stock 17s just touch the GMC flaps when backing and turning. Also dont really want a leveling kit after reading some issues here with them.

what does that mean?

Don t argue and get annoyed with a dealer that won t or can t help you. There are several # s, one of them is 1-800-222-1020. I ve never had the dealer be so nice as after I called GM and told them I was unhappy with the product. I didn t bad mouth the dealer to GM , just gave them the facts on warrenty work that the dealer didn t seem too excited about doing. (This was my painted molding post from Jan/08). GM gave me a case # and called me twice a week until I was happy.
