Took car 2019 Dodge Charger with tires to firestone dealer in Sterling Heights, Michigan because of cracks in sidewall and splits all around inside of tires by outside tread on both sides of tire. They told me Firestone does not warranty OEM tires, and the cracks are superficial. This is BS cracks in tires only get worst because they flex. As I tried to talk to them about replacing, they hung up the phone 2 times User's recommendation: Do not buy Firestone tires if buying new car make dealer change tires if on car.
