After about twenty minutes of driving the TPMS light would start flashing and shortly after it would stay on for good. When I got home I played around with the switch again and got the light to turn off but again after a short while the light would come. Couldn't quit figure it out at first, but then I realized that my summers were sitting in the garage near the car so it was seeing the TPMS from those wheels but as soon as I got out on the road the TPMS signal was lost and the warning light came on. I thought it was kind of cool that it was picking up the unmounted wheels. Just thought I would share that little experience with you guys...

It is still unfortunately too stupid to tell you which tire is low. Most manufacturers these days not only tell you there's a problem, but give you the option of seeing what the actual pressures are in each wheel.

I have wheels that do not use TPMS so this is my way around them for full time use.
