Tire Pressure Monitoring System

Tire Pressure Monitoring System or TPMS, is an electronic system to monitor the air pressure inside a tire.

HOW DOES TPMS WORK?

To help you make informed decisions about TPMS, it is important to know how each system – Direct and Indirect – works. Direct uses a sensor located in the tire assembly that transmits data to your vehicle’s computer system. It measures the tire’s pressure and notifies the driver when pressure drops 25 percent or more below the manufacturer’s recommended level. Indirect TPMS uses the Anti-Lock Braking System (ABS) to gauge tire pressure by measuring the difference in diameter of each tire. Purcell Tire’s expert technicians can tell you which system your vehicle uses.

WHAT ARE THE BENEFITS OF TPMS?

TPMS notifies you when your vehicle’s tire pressure is low or going flat. By helping you maintain proper tire pressure, TPMS can increase your safety on the road by improving your vehicle’s handling, decreasing tire wear, reducing braking distance and bettering fuel economy.

WHY IS TPMS NECESSARY?

To help drivers recognize the importance of tire pressure safety and maintenance, Congress passed the TREAD act, which requires most vehicles made in 2006-07 and ALL made thereafter to be TPMS equipped.

IS YOUR VEHICLE EQUIPPED WITH TPMS?

If your vehicle is equipped with TPMS, a “low tire pressure” warning light will appear on your dash when the key is turned to the “on” position.

HOW CAN OUR TECHNICIANS HELP?

If your vehicle’s TPMS warning indicator light comes on, there is a tire pressure problem. Stop into Purcell and our expert technicians will give you the proper tire service and care for your vehicle. They’ll check your tire pressure and perform a system test on all of your tire sensors to diagnose the problem. Once our technicians address your vehicle’s tire needs, they’ll then suggest the proper maintenance to get you back on the road.

WHY DOES TIRE MAINTENANCE WITH DIRECT TPMS COST MORE?

Direct TPMS equipped tires cost slightly more to maintain than non-equipped tires because proper care requires extra parts and labor. The valve service kit includes the valve core, cap, nut and o-ring (seal), which will always be replaced when a tire is dismounted for service or replacement. A special TPMS tool and additional time are also needed to check and reset the sensor system.
