OK, to make a long story short, I had a 2018 4WD, Crew Cab that got totaled. I bought another 2018 as near like it as possible, right down to the color, but it's a Z71 (first 2018 was not). Both have bone-stock suspension and the first one had Cooper Discoverer AT3 xlt (275/70/18). So yesterday, I had those same tires mounted on the replacement truck and they're rubbing at full lock. Those same tires on the same rims (a 5646, FWIW) didn't rub on the first truck. Is the Z71 suspension different?
I bought both trucks used, but I know for a fact that neither truck had/has a lift kit or even a leveling kit. I suppose it's possible that there were spacers behind the wheels on the first truck, but I never had them off and it's gone now so I can't check. Other than spacers or the possibility that the Z71 has different suspension, what could cause rubbing in one truck when an identical setup in another truck doesn't rub?
