Low tire warning question
Quick question - this morning our low tire warning light came on for a few minutes (maybe 5 minutes) then went off again. The tires are definitely not low. Is it possible that it was "sensing" another Lexus' sensor nearby (there was one right behind us), or is this not a radio-wave thing? (Obviously, I have no clue how the tire sensors work).

It should not sense the other Lexus' tire pressure sensors since each TPMS computer has the ID# of the tire pressure sensor that is installed in your car programmed into it. I would adjust the tire pressure on all 4 tires when the tires are cold and re-initialize the tire pressure setpoints.

I think the tpms is crap. When I had my rim fiasco I was ridind around with no sensors and the system didnt even make a noise or alert me that anything was wrong. I just check the pressure every 4-6 weeks. I am running high pressures in my tires to avoid dents and I live in AZ so the temp will probably be 100+ in a few months( it was in the low 80's today) therefore the pressue can jump up really quick
