Understanding Tire Pressure Monitoring Systems (TPMS) for Your Car

Did you know...

that most cars, mini-vans, and light trucks made in 2008 or later are equipped with a tire pressure monitoring system (TPMS)? Even some older vehicles have this feature. TPMS is a system with sensors on each wheel that keeps track of tire pressure.

When your tire pressure drops 25 percent below the recommended level by the manufacturer, the sensor sends a signal to a monitoring unit, which then lights up a warning on your dashboard. This warning tells you it's time to add air to your tires.

There are many benefits to driving with properly inflated tires. First, it saves you money. Having the right amount of air in your tires improves fuel economy. Properly inflated tires also wear evenly, meaning they last longer. Driving with under-inflated tires is like driving on sand - it uses more fuel. 

Safety is another important benefit of having properly inflated tires. Under-inflated tires can get hotter and may fail, potentially causing accidents. Your car and tires perform better and safer when the tires are properly inflated.


Many consumer groups, lawmakers, and car manufacturers support TPMS systems because they believe they save lives, prevent property damage, and reduce inconvenience. However, TPMS systems come with costs.

The systems are built into the price of the car, and the sensors' batteries need replacing over time. Parts may break and need replacing, especially in colder climates where ice and salt can damage them. Additionally, every time a tire is serviced, the TPMS system needs attention, requiring equipment and training for technicians.

Despite these costs, service centers like David's Automotive Repair prioritize your safety on the road. However, they want you to understand why prices for tire services may increase due to TPMS systems.

It's essential to remember that the TPMS warning only alerts you when a tire is significantly under-inflated. You should still check your tire pressure regularly, ideally at every fill-up, or at least once a month, for safe travels.
