The valve stem for a TPMS-equipped vehicle performs the same function as its predecessors – it keeps air in the tire. If it doesn't seal properly and leaks air, the result is the same: an underinflated tire, and a low tire is a dangerous one.

Full Answer

When do you need a TPMS valve stem repair kit?

Like tires, valve stems become brittle with age, which means a tire pressure monitoring system repair kit should be used whenever the tires are replaced. Our OES TPMS valve stem kits are made by the same manufacturers who supply automakers with their TPMS sensors.

Do TPMS valve stems differ between cars?

For example, cars that use a Direct TPMS have sensors that are installed in the wheels of the car so that the sensors themselves monitor the air pressure in the tires. And because of this very fact, the valve stems of the TPMS do differ from the other cars.

What is included in a TPMS service kit?

Each TPMS service kit comes with the stem, valve and seals needed to replace the valve stem assembly on a TPMS-equipped wheel. Like tires, valve stems become brittle with age, which means a tire pressure monitoring system repair kit should be used whenever the tires are replaced.

Can a TPMS sensor be reused on a tire?

No matter the type of stem, carelessness can result in a broken sensor or even a customer being stranded with a flat tire. Anytime a clamp-on TPMS sensor is reused or replaced on a wheel, it is necessary to install new seals and valve stem nuts to ensure proper sealing around the sensor valve stem.

Most TPMS sensors run on batteries that are built into the sensor and these batteries are not replaceable. The life expectancy of the lithium ion batteries in a TPMS sensor is anywhere from 5-10 years.

Is TPMS on rim or tire?

A tire pressure monitoring system (TPMS) is a system in your car that alerts the driver when the air pressure drops inside the tire. This is an electronic system that connects the sensor (placed on the rim) with the monitor (on the vehicle's dashboard) in order to show whether the tires are properly inflated or not.

What is a TPMs tire?

The purpose of the tire pressure monitoring system (TPMS) in your vehicle is to warn you that at least one or more tires are significantly under-inflated, possibly creating unsafe driving conditions. The TPMS low tire pressure indicator is a yellow symbol that illuminates on the dashboard instrument panel in the shape of a tire cross-section (that resembles a horseshoe) with an exclamation point.

What is indirect TPMS?

An indirect TPMS typically relies on wheel speed sensors that the anti-lock brake system uses. These sensors measure the rate of revolution each wheel is making and can be used by on-board computer systems to compare with each other and to other vehicle operation data such as speed.

How fast can Bridgestone tires go?

There’s never a good time for a flat. That’s why Bridgestone DriveGuard tires are masterfully engineered to keep you moving for up to 50 miles at speeds up to 50 MPH without disruption.

Does a tire pressure sensor work?

Sensors in a direct TPMS may even provide tire temperature readings . The direct tire pressure monitoring system sends all of this data to a centralized control module where it’s analyzed, interpreted, and, if tire pressure is lower than it should be, transmitted directly to your dashboard where the indicator light illuminates. A direct tire pressure monitor usually sends all of this data wirelessly. Each sensor has a unique serial number. This is how the system not only distinguishes between itself and systems on other vehicles, but also among pressure readings for each individual tire.

Can TPMS be used as a replacement for air pressure?

Even though a TPMS can deliver accurate alerts when properly maintained, it’s not a replacement for manual air pressure checks, consider it just another item in your car maintenance toolbox.

Does a TPMs work the same way?

Not every TPMS works the same way. The illumination of the low tire pressure indicator represents the final step in the process of either an indirect TPMS or a direct TPMS.
