Yes; said it to both service advisors. Both said "we swap wheels all the time". Question to the group; is this something that wheel spacers might fix? I have no experience with them.

Yeah, heading where there's snow and mud;. That's the issue....those stock General Grabber all season worry me.

Ugh; never thought of that. Thank you sir.

Ok, folks; what did I do wrong? '19 Sierra SLE 1500. Bought used a few months ago; came with stock 17" wheels and all season tires. Want to swap wheels (and the tires on them) and put on a set of 18" wheels (with 265/65/R18 AT tires) from my '08 Silverado. Dealer told me to swap them then come in to have the speedometer reprogrammed. Expect a TPMS error but evertything else should be easy. Made the swap this afternoon and things fell apart. When I start the truck I get all sorts of errors (Service Brake Assist, Brake System Failure, Serivce ESC) plus a check engine light and a traction control light. When I put the truck into drive or reverse it will not move; feels like something is holding it from moving. And yes, all the jack stands and wheel chocks are removed; checked that 20 times. 2 different dealers are stumped; want me to either put old wheels back on or have it towed in. Was supposed to leave on vacation Sunday; that's now scrapped. About to call OnStar and see what errors they can see on their end. Will pull front wheels off to ensure nothing got pinched but can't see anything obvious. One dealer said to relearn TPMS but he couldn't believe that would have caused all of the errors. Any ideas? Thanks, Dave
