A tire pressure monitoring system (TPMS) is an electronic system that monitors the air pressure in a vehicle's tires. TPMSs can be used to warn the driver of low tire pressure, which can improve safety and fuel efficiency.
How does a TPMS work?
There are two main types of TPMSs: direct and indirect.
1) Direct TPMS uses sensors mounted inside each tire to measure the air pressure. The sensors then transmit the pressure data wirelessly to a receiver in the vehicle, where it is displayed to the driver.
2) Indirect TPMS uses the vehicle's wheel speed sensors to estimate the tire pressure. This type of TPMS is less accurate than direct TPMS, but it is also less expensive.
What are the benefits of a TPMS?
A TPMS can provide several benefits, including:
* Improved safety: A TPMS can help to prevent accidents caused by low tire pressure. Low tire pressure can reduce a tire's traction and make it more susceptible to punctures and blowouts.
* Increased fuel efficiency: Underinflated tires can increase a vehicle's rolling resistance, which can reduce fuel efficiency. A TPMS can help to keep tires properly inflated, which can improve fuel efficiency.
* Extended tire life: Underinflated tires wear out more quickly than properly inflated tires. A TPMS can help to extend the life of your tires by keeping them properly inflated.
* Peace of mind: Knowing that your tires are properly inflated can give you peace of mind when driving.
Is a TPMS required by law?
In the United States, TPMSs became required on all new passenger cars and light trucks in 2008. Some states also require TPMSs on older vehicles.
If you are thinking about having a TPMS installed on your vehicle, be sure to consult with a qualified mechanic to find the best system for your needs and vehicle.
