That thing is annoying when it goes off though. The first time mine went off was at my dad's house. It was nice the day before and got really cold over night. I didn't bother to stop to get air in the tires since I was driving down to Potts to go wheelin any how. Right after I was done wheelin I stopped to get gas and aired up to about 35 psi hot. The light has been off ever since.
