TPMS has been mandatory in the U.S. since 2007. It turns out riding on under-inflated tires is dangerous, and people don’t regularly check their tire pressure.

My car will not exceed a certain speed if TPMS is malfunctioning.



Conveniently it cost around $200 every 5-7 years to replace all 4.


Driven cars much longer than that without replacing TPMS.


It amazes me that people don't notice. I was driving with a friend once and had to tell them to pull over because they had a puncture.
