All About Your TPMS in Commerce

July 4, 2021



Commerce drivers know that underinflated tires wear out more quickly. Underinflation is also a major cause of tire failure for Michigan auto owners. More flats, blow outs, skids and longer stopping distances are all results of underinflated tires.

It's hard for many Commerce drivers to tell when a radial tire is underinflated. If your owner’s manual recommends 35 pounds of pressure, your tire is considered significantly under-inflated at 26 pounds. The tire may not look low until it gets below 20 pounds.

Uncle Sam to the rescue! A recent U.S. federal law required vehicle manufacturer’s to include a Tire Pressure Monitoring System - or TPMS system - in all vehicles. Many Canadian vehicles have them as well.  The system is a dashboard mounted warning light that goes off if one or more of the tires falls 25% below its pressure recommendations.

Obviously, all of this doesn't come free for Commerce car owners. Government studies have estimated the net costs. Of course, the TPMS system itself will cost something. Maintaining the system will have a cost, replacement of worn or broken parts and tire repair cost increases. The net cost is estimated to be between $27 and $100.

Michigan service centers have purchased new scanning equipment to work with the TPMS sensors and updated expensive tire change equipment to better service wheels equipped with the new monitoring systems.

Commerce Auto Repair service advisors have been trained on many systems and new tire-changing techniques. All of this adds up to significantly increased cost to the service center to perform what was once a very inexpensive service. So if you've noticed the cost of flat repairs, tire changes, and rotations going up, please keep in mind that it's because of government mandated safety equipment. Your Commerce service center just wants to keep you safely on the road - and it's committed to do so at a fair price. Remember, this change will help you avoid the most common vehicle failure, and possibly a catastrophic accident.
