Have you noticed an increase in price when you get a flat fixed in Troy or your tires rotated? It might be the result of your TPMS, or Tire Pressure Monitoring System.

The federal government began requiring a TPMS system on 2008 model year passenger vehicles and light trucks. Some 2006 and 2007 models may have them as well. The system has a warning light that is mounted on the dashboard that will go on if one of the tires becomes severely under inflated.

Why the new requirement? Because underinflated tires are the number one cause of tire failure. Tire blowouts cause dangerous and sometimes fatal accidents. Underinflated tires also need longer stopping distance and can skid, both of which also present dangers on Michigan roads. Many flat tires can also be prevented by proper tire inflation, and though this may seem an economic consideration, Troy auto owners who have changed a flat on the side of the road recognize that this has serious safety concerns as well.

Advances in tire technology, specifically the development of radial tires has made it harder for Troy auto owners to recognize when a tire is underinflated. At a recommended pressure of 35 psi, a tire is seriously underinflated at 26 psi. But the tire doesn’t look low on air until it reaches 20 psi. This raises concerns about vehicle owners being able to tell when their SUVs are a safety hazard on the road. Hence, the TPMS.

So, like seatbelts, the essential TPMS system is expected to save a lot of lives. The technology has been in use in race cars for years, and now it’s being mandated for all passenger cars, SUV’s, mini-vans and pick-ups. Besides warning Troy drivers when their tires need air, the system is required to indicate when it is malfunctioning.

This increased safety won’t come without increased costs to Troy motorists. Estimates regarding the cost of maintaining the TPMS on your vehicle run from $27 to $100. Also, there will be an added cost for tire repair. Troy service centers have had to purchase new scanning equipment to work with TPMS sensors and other vital equipment to repair tires and wheels equipped with TPMS. Tuffy Tire & Auto Service Center Troy service professionals have to be trained to use the new equipment. These costs will have to be passed on to Troy car owners.

Further, whenever a tire is changed, the Tuffy Tire & Auto Service Center Troy service professional will have to deal with the TPMS. Sensors will have to removed, then re-installed and re-activated. Sometimes the act of changing a tire will damage a sensor, and it will need to be replaced. These extra services will come at an added charge to Troy car owners.

Tire rotations will require that the TPMS be re-programmed. And whenever a vehicle’s battery is disconnected, the TPMS will require re-programming as well.

The TPMS itself will require attention – it contains batteries and sensors that will wear out and need to be replaced.

So, if you’ve noticed an increase in the cost for car care at your Troy tire center, it may not be the economy. It could be the cost of the TPMS in newer vehicles. Before you dash off an angry letter to Congress, however, stop and consider what you’re paying for. If predictions are correct, the TPMS will save lives, and that will be a benefit to all of us.

Of course, no warning system will save lives in Troy if car owners don’t pay attention to it. And remember that the warning doesn’t come on until the tire is severely under inflated – you still should check your tire pressure at least once a month. Troy motorists can prevent accidents and potentially save lives without a warning system by keeping their tires properly inflated.
