Our Ford Focus has the "tire light" that seems to light-up whenever the temps fluctuates. Really cold to a sudden warm-up or the other way around. If we're headed home, we cranked up the air compressor and check all the tires. If we're on the road, we find a place where we can add some air or let some out depending.
Gotta love the new auto technology...NOT!
