How do tire-pressure monitoring systems, without sensors in each wheel work?
Systems without in-tire sensors use the vehicle wheel speed sensors. A low tire will be shorter than a properly inflated tire. The shorter height means it must turn faster to keep up with the other tires. By monitoring wheel speed, an onboard computer can infer which tire is low. Also see our tire pressure article for a great deal more information.
