Restore TPMS Performance for Safe Driving

The Tire Pressure Monitoring System (TPMS) is an electronic system designed to detect under inflated tires. The TPMS has been a requirement on light motor vehicles in the United States since 2007, as documented in the TREAD Act.

When the TPMS detects an under inflated tire, it alerts the driver with a dashboard warning light. This alert provides the driver with more time to react.

Direct TPMS vs Indirect TPMS

There are two primary types of Tire Pressure Monitoring Systems: Direct (dTPMS) and Indirect (iTPMS). Manes Auto Repair services both types, explained in more detail below.

Direct TPMS: Most vehicles have a dTPMS. In this system, each tire gets its own sensor located on the inside or outside of the tire. The individual sensors report to your car's on-board computer. A dTPMS often works with batteries. As a result, tire sensors have a limited lifespan. However, most systems only record data when your vehicle is running in an effort to make the battery last longer. 

Indirect TPMS: An iTPMS monitors each tire's rotational speed to determine whether or not a tire is at proper inflation levels. This is because an under inflated tire has an overall diameter that is less than a properly inflated tire. As a result, the under inflated tire needs to rotate faster to cover the same distance as the properly inflated tires. If the iTPMS identifies a tire rotating at a different speed, it alerts you to an inflation problem. Your iTPMS may also be able to catch over inflated tires since they rotate more slowly than the other tires.

3 Good Reasons to Repair the TPMS

The Tire Pressure Monitoring System is a valuable part of your car for more than one reason, including:

• Road Safety: An early warning about a flat tire can make a big difference. With a TPMS alert, you have more time to react to the situation and get your car off the road for safety and before you cause damage to the wheel. 
• Tire Life: When a tire isn't at the correct inflation level, the tread wears faster and the tire doesn't provide you with as good of a defense against road hazards
• Tire Performance: A properly inflated tire provides better wet and dry handling; underinflated tires make it easier to hydroplane, crash from a tire blowout, or skid on a curve.
