If your vehicle was made after 2007, it likely comes with a Tire Pressure Monitoring System (TPMS). This handy technology is designed to alert you when your tire pressure is too low, but it offers many more benefits than just a warning light. Understanding how TPMS works and how to use it can help you keep your tires in great shape and improve your driving experience.
TPMS uses sensors inside each tire to monitor pressure. There are two types of TPMS: direct and indirect. Direct TPMS has sensors that measure pressure directly and send the information to your vehicle’s computer. Indirect TPMS uses the vehicle’s anti-lock braking system (ABS) to monitor wheel speed—if one wheel is spinning faster than the others, it means the tire is underinflated (since underinflated tires have a smaller diameter).
One of the biggest benefits of TPMS is convenience. You don’t have to manually check your tire pressure as often—TPMS will let you know when there’s a problem. This is especially helpful for busy drivers who might forget to check their tires regularly. TPMS also provides real-time information, so you can address pressure issues as soon as they arise.
TPMS also helps improve safety. As we mentioned earlier, underinflated tires are a major cause of accidents. TPMS alerts you to low pressure before it becomes a serious problem, giving you time to add air or get your tires checked. It can also help you avoid blowouts, which are often caused by severely underinflated tires.
Another benefit of TPMS is that it can save you money. Properly inflated tires last longer, so you won’t have to replace them as often. They also improve fuel efficiency, which can save you money at the gas pump. Over time, these savings can add up to a significant amount.
To get the most out of your TPMS, make sure you understand how it works. Read your vehicle’s owner’s manual to learn about the warning light—some systems will let you know which tire is underinflated, while others just give a general alert. If the warning light comes on, check your tire pressure as soon as possible. And remember, TPMS is a supplement to manual checks, not a replacement. You should still check your tire pressure manually at least once a month.
