Depending on where I look I get a different answer, Is the bolt pattern on a 2013 Yukon Xl 2500 4x4 still 8 x 6.5, or did it change to 8 x 180? I want to upgrade my rims and tires and just want to make sure I get the right rims. The stock rims are 17 x 7.5, and I put a levelling kit in it so I'm going to a 285 (33") tall tire, Would 8" wide rims fit without rubbing? How about going down to 16 inch rims? Any help would be appreciated.
