Tire Pressure Valve Caps (set of 4)

Take the pressure out of knowing when your tires are filled to their optimum levels. It's a simple system. When tire pressure has reached its maximum normal level, our valve caps show green—a 'go' for better fuel efficiency, increased tire longevity and smoother ride. When the green recedes, it's time to get your tires checked. No more guessing. No more worrying. Screw-on caps replace existing valve caps in a snap; no tools required. Available in two pressure levels appropriate for most cars, pick-ups, vans, SUVs and CUVs.
