The 2007 New Body style came with 265/70/17 tires and I am looking to put something bigger on it. What can I go with w/o a lift? Doesn't look to be much clearance when the current wheel/tire is turned. Will a 285/70/17 or a 315 fit?

Also talked with the dealership and they stated I would need a GM code to adjust the computer for the larger tires and GM would only provide the code for approved tire sizes. Obviously everyone runs larger tires so how is the adjustment done for speed and mileage?
