Hey all! I have an issue with my X3...had to replace one tire due to a sidewall gash, and now have one tire at 10/32, and three at 6/32. Tired was replaced for 'free' at Discount Tire with the certificate. To avoid xdrive problems, I want to shave the new tire, but am really struggling to find anyone that does that. Any knowledge here? I'm in Flagstaff, but happy to load the tire into another vehicle and make a drive. Thanks!
