AIR ALERT Valve Cap

Considering that the price of gas is still high, it is important to do what you can to maximize gas mileage. Having the correct tire pressure is one way to save on gas. To keep your tires properly inflated, use the AIR ALERT Valve Cap. This small and simple device is designed to replace the regular dust cap on your tires, and it will have virtually no impact on the wheel balancing. Here's how the cap works: Once the tire pressure falls about 4 psi below the correct pressure, the cap will start blinking. This active warning will be easily seen by you as you approach your vehicle. Then, you can head to the filling station for more air...and gas.
