Your car may have T.P.M.S

T.P.M.S stands for "Tire Pressure Monitoring System." This system will alert the driver if the pressure in any of the tires falls below 20% of recomended cold psi. The sensors are installed in each wheel send a signal to the dashboard when air pressure is low.

Replacement parts

Each time you replace tires the T.P.M.S valve components should be replaced. Reusing seals can lead to slow leaks and reusing the hex nut can lead to corrosion. Plastic sealing caps and electroless nickel plated valve cores, prevent ruining the valve which would lead to replacing the entire sensor! Replacing these components will save you money.
