 I'm Brad Keselowski, driver of the number two discount tire Ford Fusion. If I've learned anything in my years on the track, it's that properly inflated tires make all the difference. Once each month and before road trips, take the time to check your air pressure or stop by a neighborhood tire retailer. Not only will properly inflated tires keep you and your family safe, but also improve fuel economy and handling. A message from the U.S. Tire Manufacturers Association.
