Driving with your tire pressure a few pounds low can reduce tire life, cost you in fuel efficiency, and even lead to an accident. Tire Minder's color coded indicators let you monitor tire pressure at a glance, without even bending down, so you always know you're running at the proper inflation. Simply fill your tires to the recommended pressure and replace your existing valve caps with Tire Minders. 26-40 psi caps fit a wide range of vehicles. Imported.
