Despite being advertised as quiet tires, these tires make loud humming noise at 60 mph or higher speed, making them unsuitable to use. I ended up filing a credit card dispute and returning them for exchange-meaning I had to haggle with Firestone to avoid letting them rip me off. They initially wanted $140 in additional costs to exchange them, nearly half of the money I spent purchasing the first set. Avoid them and Firestone complete auto care.
