Understanding Tire Pressure Monitoring Systems (TPMS) for Your Car

May 9, 2024

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.

While most people think cold kills batteries, extreme heat actually wears them down faster.

If your battery is more than a few years old, or if your car is slow to start, now’s the time to get it tested. Nobody wants to be stuck with a dead battery in a hot parking lot or on the side of the road. At David’s Automotive Repair, we offer quick and accurate battery testing to give you peace of mind before the next heatwave rolls in.

Belts keep systems like your alternator and power steering working. Hoses carry important fluids like coolant and help your engine stay at the right temperature. Over time, heat and wear can cause them to crack , fray , or leak . If a belt breaks or a hose bursts while you’re driving, it could lead to engine damage or even leave you stuck on the side of the road. That’s why it’s smart to have them checked regularly—especially before long trips or hot summer days. If you’re unsure about the condition of your belts and hoses, we’re here to help with a quick check. Call 972-625-1836 to make a reservation to have your belts and hoses inspected by a certified technician.

High temperatures can cause fluids to thin out , break down faster, or even evaporate —putting your car at risk for overheating or part failure. If your coolant is low, your engine can overheat. If your oil is dirty or your transmission fluid is old, important parts may not be properly protected. The summer heat makes staying on top of fluid checks more important than ever. At David’s Automotive Repair, we’ll inspect all your fluids to make sure your vehicle is ready to take on the summer. Call 972-625-1836 or go online to reserve your visit.
