One year after purchasing this new vehicle, the two rear tires were worn to 4/32nds. The dealer advised they need to be replaced. I am [XXX], with no accelerated starts or hard braking, so after one year and 7,500 miles, the rear tires were up for replacement. The dealer reluctantly did a forced balance, which I paid for and BMW Corporate reimbursed. They did not do anything for toe/camber. I do not know if they were out of spec from the factory for balance, toe/camber/alignment or if the tires were faulty. The dealers' only guidance was to replace. So I went to a Firestone dealer and had the tires replaced 255/35R19 96Y for $200 less than the BMW dealer wanted to sell them.
