I went to move the MCS into the garage on a VERY cold night and got a "low tire" warning. The tires look fine. I thought the extreme cold had brought the pressur ebelow some treshold. The other day, at ~30F I moved the car again and it still said the same.

I had no idea the MCS had a TPMS. I assume it is a basic treshold alarm-style TPMS. What is this pressure. Do I really have a flat, or is the tire at 29psi, for example and it just doesn't like it?

Naturally, I've been sick and very busy and have not yet had it inspected (already past due as of yesterday). I'm 100% this low tire thing will fail me.

Thanks.
