Some tires are equipped with tire tread indicators, to let you know when the tread is nearing the unsafe range. Additionally, you can purchase a tire tread depth gauge at an auto parts store to measure the tire tread depth. We perform a basic safety inspection whenever you bring your car in for service, so we will let you know the condition of your tires. You can always bring your car in between service intervals to have us inspect your tires if you have any questions about the tread depth or any odd wear patterns on your tires.
