Hello, I recently purchased a '12 gmc Yukon XL. One tire had a defect so dealer changed it. Tread depth on 3 are 9/32's and the other one is 12/32's. Do have anything to worry with regards to 4wd and or anything else? Dealer is very reputable and said it isn't and issue but thought I would check. It is not the Denali version so no AWD.
Thanks for any help.
