Do you need to reset tpms after new tires?
Most modern cars require you to reset TPMS after replacing old tires with new ones or simply rotating them.
Even if the tire has been inflated to the proper or suggested PSI, the TPMS warning light would be still on and need resetting or re-calibration.
Why Does TPMS Light On?
When TPMS lights on, it means that the system is recognizing irregularities or problems in your tire system.
The light is to warn you about potential or actual tire problems so you can respond to them immediately, especially when the tire pressure isn’t at the correct PSI.
However, TPMS can also be triggered as you change, rotate, or inflate the tires.
Is it Dangerous Driving with Low Tire Pressure Light?
TPMS light would typically be on as there are changes in the tire pressure condition and it works as a warning for you. It’s definitely dangerous to drive your car with tire pressure below the proper PSI.
Once you’ve noticed the TPMS light is on, check your tires and inflate them to the proper PSI before resetting the system.
What Does TPMS Fail?
The most common cause of TPMS failing problems is malfunctioning sensors in the system. The sensors may require replacement because of the damages or the end of their lifespan.
However, it can also be caused by the dead batteries that power the sensors where the whole sensor replacement isn’t necessary. When the TPMS light can’t be reset, it could be a sign of TPMS failures.
When the TPMS lights on, you’d need to perform re-calibration so the system can relearn the changes. These include when the tires are rotated, inflated, changed, or damaged.
After calibration, the TPMS light would go off as the system recognized the changes. A scan tool isn’t necessary as you can manually reset TPMS referring to the resetting procedure that varies for car models.
However, it’s very important to ensure and inflate tires to the correct pressure or settle all related issues before resetting the TPMS light.
