At what pressure does it trigger the TPMS? - Toyota Yaris Forums

I had heard that the trigger pressure was around 17 psi - basically the point at which it's not just a question of wear, but of safety. TPMS does NOT mean you shouldn't check 'em by eye just as often to keep them sweet.

It's somewhere around there for the low threshold and around 70 for the high threshold. Also, it triggers if any tire deflates more than about 6psi in 30 seconds.

That is good to know. So it basically means "if you see the light, pull over and check NOW!"
