How Do I Reset My Tire Pressure Light?

@tirebob Would you say that 7 years is about time for TPMS batteries to be changed out?

TPMS batteries cannot be changed out. They are molded in plastic solid state, otherwise moisture etc would be able to work its way in under pressure etc and they would foul in no time. When the batteries die, you replace the entire sensor.

Time frame does vary a lot. For the most part, sensors lie dormant until the car is started or under motion so for some people they can last 10 years or more and other people they die in just a few years. Truthfully I think like any battery, sometimes they just get fucked due to environmental conditions, glitches, etc. I even get brand new ones in box sometimes that the batteries are already dead. Go figure.

Sorry my bad, I mean the button to turn off traction control is disabled when the TPMS light is on so traction control will be on all the time which probably doesn't matter to most people.

Gotcha! That makes more sense. I was about to crack out the "potato" memes for the car companies.

Ah gotcha. It sounds like I should have swapped out the OEM sensors when I mounted the winters to the OEM wheels last year.

It's been 6 years but I didn't even know how TPMS worked.

They are not hard to change out usually. Some vehicles tire and wheels dictate a full dismount but if you have a typical OEM setup, most of them can just be dealt with by breaking the bead and just holding the tire down and changing the sensor. If you put a different one in and the weight is different it may need a balance but if the same sensor is going back in then it should even need that so long as the tire stays on the rim in the same position.
