TPMS Light Not On After Installing Winter Tires With No Sensors

I was wondering if anyone experienced this? From my knowledge, no sensors were installed...I am almost tempted to let 10-15 lbs of air out of 1 tire to see if a light pops on... More about it herehttp://forums.genvibe.com/zero...39273

After I put my winters on, the light didn't come on until a week later. Was on for a while, then went off again. I haven't paid that much attention, but it seems to me that the light is off more than it is on!

You just need to go for about a 20 minute drive without turning off the ignition for it to "realize" that there aren't any sensors there.Where I park in my driveway at home, it's about 20 feet from where I'm storing my tires in the basement. If I have the car run for a couple of minutes in the morning before taking off (to clean off windows, etc.) - sometimes it will pick up the signal from the sensors and turn the light off. At the exact same point into my daily drive, the light will start flashing again. If I just do short trips around town - it will stay off until I give it a longer run again. I'm pretty sure it's time based, not distance. I was just surprised that they had enough range for my car to "see" them where it is. Makes me wonder about overall battery life in those sensors...John
