| Description of the problem | Toyota pre-2007 tpms (tire pressure monitoring system) design flaw. It only works when you "suddenly lose pressure" while vehicle is moving above 20 mph. It does not detect tire pressure loss any other time, even if one tire is at zero psi and you start driving, or if you hit a nail at a red light and tire pressure went to zero before the light turned green when you start moving again. Compounded with run-flat tires, the driver may never know they have a flat until the tire explodes. |
