I have a 2016 Subaru Forrester 2.5 limited with the original tires. The car has 31,500 miles and the tires are sort of bear. They supposed to be guaranteed I believe up to 50,000 miles. How does that work? Can I go back to dealer and say change my tires cause they’re kind of bald or has too much time pass for that to happen? Can someone explain how tire warrantees work? Thanks.
