Maintain proper tire pressure for increased safety, fuel mileage and tire life! By monitoring the Tire Pressure Monitoring System's safety cap color-configuration, you will greatly reduce the risk of flat tires, accidental roll-over and hydroplaning due to low tire pressure. 3 stages include: Green, which verifies a properly inflated tire; Yellow which warns that the tire is approximately 4 lbs. low, and Red (danger zone) which alerts you that the tire is approximately 10 lbs. low. Simply monitor these colors on a regular basis to ensure your tires are properly inflated at all times. Instructions included. Set of 4 caps
