An old post being brought back up actually helped me (I say this as some people get irritated from old topics be re-hashed).
Anyways with my winter tires on my "tire pressure light" kept coming on and I just dealt with it for the time being. I had no idea the factory wheel tire pressures were built into the system to set off the "warning". I assumed different tires could be used and then set the indicator to monitor those pressures(my winter wheels/tires being all the same size and same pressure opposed to staggered like the OEM set-up).
A full day later no light as I set my winter wheels to the factory pressures. Fingers crossed.
I assumed the monitors Tirerack installed in my winter set-up maybe weren't fully compatible but the problem now seems to be fixed.

TP
So many people on this forum have reported (usually in panic mode) some sort of malfunction, real or otherwise, that you will be far better off buying a quality tire pressure gauge and check your own tires weekly. Similar to what we have been doing for decades but I still have to set the pressures initially with a quality gauge.
After two years, my own car's TPMS has been operating normally.
I think this Federal requirement for TPMS came to be because of the Ford Explorers on underinflated Firestone tire rollovers a few years back. These days, everybody is filling their own gas tanks and never checking their tire pressures and so the government decided that we would have these automatic systems, like it or not.
When I am in creeping along in traffic, I often notice that the rear tires on the vehicle ahead of me (usually some SUV) are underinflated and it's usually the left rear for some reason. Try this yourself and I think you will see the same thing.

As nyca said just going a few miles down the road would/will trip the monitor otherwise.
