I think you mean "TPMS". TPS is the acronym for the "Throttle Position Sensor". Cover the dashboard light with a piece of electrical tape if it bothers you -- I don't think any Lexus model with TPMS sounds an alarm. Yep I mean the TP Monitoring system. Electrical tape! Good idea & thanks.

I did some checking around here and I didn't see the answer to my question. What happens if TPS are not used on winter wheels for an IS250? Is it just a dashboard light that is the inconvenience or is it a warning noise too? On my Vette a boinger keeps going off with low tire pressure warning but that might not be the case with Lexus.
