Researchers at IMDEA Networks Institute, together with European partners, have found that tire pressure sensors in modern cars can unintentionally expose drivers to tracking. Over a ten-week study, they collected signals from more than 20,000 vehicles, revealing a hidden privacy risk and highlighting the need for stronger security measures in future vehicle sensor systems. Most...
TIL that these sensors transmitted via a wireless signal rather than being hardwired. I’ve never heard of them needing to be replaced due to dead batteries.
If road salt is getting into your tires, and then into the sealed battery in your TPMS… you got other bigger issues. Maybe make sure you have all your valve cap isn’t broken or missing?
It didn’t happen to me, my car doesn’t have TPMS sensors, but a buddy of mine had the cap on his valve stem corrode. The corrosion borked the entire valve stem, and he didn’t find out until he went to get his summer tires put on. It didn’t leak, but the place charged him some $ because it was a pain to remove and replace.
The system required to make them hard wired would be immensely over complicated to allow the wheels to still turn. Where ever the wire exits would also have been additional point for leaks to occur.
I’ve had one die, and just waited to replace it until I needed new tires. It was like $100 extra to replace all 4, so I don’t have to worry for another decade

TPMS batteries last a long time because they are transponders, they use very little energy, but they eventually die.
The batteries last about 10 years.
Much less when you live in a cold climate, or they get corroded from road salt.
