I have been looking for some nicer alloy wheels than my stock alloy Tahoe wheels. I found some take offs from a 2016 GMC Canyon that I like and they are a six lug wheel. The stud spread is 5.5" so I am not worried there. The Canyon is a 12-1.5 thread and my Tahoe is a 14-1.5 thread. I am worried that the wheel hole itself could be too small to be able to reuse my lug nuts and I am also worried about the center clearance area at the back of the wheel where it would need to clear my hub flange area. The seller says the wheels are coming off a diesel rig. The tire size is going from a 265/70R16 to a 265/60R18. The tire inflated height appears to be the exact same so I am not worried about turning interference unless the offset is way different. I tried to look it all up in a crossover diagram but says the Colorado/Canyon are the same from 2004 on and I am not sure of that and the seller also says he heard the wheels would not fit the 2002 Tahoe I have. Any thoughts?
