Does your vehicle have a tire pressure monitoring system?

The best way to avoid tire problems is to keep an eye on your tire pressure. Surprisingly, an estimated 25% of all vehicles on the road are riding on underinflated tires—are you a part of that statistic? Please make sure that you aren't, that is, if your vehicle isn't already equipped to do so itself. Many of today's vehicles feature a tire pressure monitoring system, which typically comes in one of two different forms: direct and indirect.

An indirect system will work through the anti-lock braking system's speed sensors, which compares one tire to the next in terms of rotation. Obviously if a tire is low, it'll rotate slower. These indirect systems, however, aren't always accurate. Especially if outside temperature is a factor.

A direct system, on the other hand, uses a pressure sensor/transmitter which is attached to the vehicle's wheel. These systems are typically more accurate, and Tire Rack has worked with a variety of wheel manufacturers to ensure that their wheels can accommodate such systems.

Typically, there is some type of in-vehicle warning system or dashboard light, regardless of the monitoring system in place. However, if you aren't sure whether your vehicle is equipped, you can look for these clues: dash light, metal valve stems or notes in your Owner's Manual.

Still not sure? Just call us. We'll help you figure it out, and then we'll help you figure out what wheels your system can accommodate.

Can you tell me what type of TPS is on the 2014 Mini Cooper S? Direct or indirect.
