What is TPMS? (TPMS)stands for: Tire Pressure Monitoring System Tire pressure monitoring systems (TPMS) are a safety device installed by the factory to alert the driver of an underinflated tire. The most common systems used is a sensor mounted inside the tire to measure tire pressure directly and then transmits this information wirelessly to onboard electronics.
Is it necessary to replace the TPMS sensors when a vehicle needs new tires?
It depends on the age of the sensors. By the time the tires are worn out, the TPMS sensors may be nearing the end of their useful service life — or they may not have enough remaining battery life to last another set of tires.Does the law require replacing a bad TPMS sensor?
It depends on your state and local laws. There is no legal requirement (yet) at the national level to replace a bad TPMS sensor if the TPMS warning light is on or flashing. That’s a decision the vehicle owner has to make regarding their own safety. Obviously, if a TPMS system has one or more bad sensors, it can’t warn the motorist of a low tire. If any vehicle owner decides not to have the sensors replace when it’s recommended the owner may be asked to sign a waiver stating that they won’t hold the service shop liable for any damage or injury from improperly inflated tiresWhy do you need it? (this is my opinion)
Well for several reasons:- NHTSA-National Highway Traffic Safety Administration ruled that all vehicle manufacturer’s that sell motor vehicles in the U.S must have a Tire pressure monitoring system installed since 2007.
- it helps you save on gas because you’ll know when your pressure is low.. low tire pressure causes you to waste gas because of the increased friction.
- It tells you when you may need to service your tires or sensors.
