Why the tire pressure sensor matters

Some tire stores charge a small fee to rebuild the tire pressure sensor when they replace a tire. It may sound like a scam, but it’s completely legitimate. No shop wants to risk damaging four $100 tire pressure sensors while changing your tires. So the technician unscrews each one from the wheel and lets it drop inside the wheel before dismounting the old tire. Once the sensor’s gasket is disturbed, it can’t be reused. To guarantee a leak-free seal on the reinstall, the shop uses a new gasket, washer and retaining nut. Then a special torque wrench is used to tighten the nut. So you’re paying for the parts and labor.
