 Austin Sender here, driver of the discount tire, number two Ford Mustang, and 2022 NASCAR Cup Series Rookie of the Year. Having the right tire pressure on the racetrack is crucial to my success. Tire pressure is also critical to keeping you safe on the road. Whether it's for safe stopping distances in all seasons or getting the best gas mileage, you want to keep your vehicle's tires properly inflated. Check your tire pressure at least once a month or stop by a local tire retailer for an air check. A message from the U.S. Tire Manufacturers Association.
