So I just purchased this truck and am confused by the wheel sizes. From all the reading I have been doing. I see that 2011 and newer trucks used 17x 7.5 180mm bolt pattern and also 18x8 180mm. and trucks 99-2010 used 16x6.5 6.5 bolt pattern. Well my truck the 2007 NNBS says on the sticker that it originally came with the 17x7.5 wheels with 265/75/17 tires. Does this mean it used the 17" x 7.5", 8 Lug, 6.5" Bolt Pattern ? I just need to know what bolt pattern so I can replace these 16' rims with some takeoff 17's or aftermarket.
