 Hi, I'm Brad Keselowski, driver of the number two discount tire Ford Mustang. If there's one thing I've learned after years on the track, it's that having the right amount of pressure on your tires can make or break performance. Properly inflated tires are essential to the health of your car and to keep you driving safely. Check your tire pressure once a month, especially before road trips, or stop by your neighborhood tire retailer for help. A message from the U.S. Tire Manufacturers Association. WDEL.
