Tire Pressure Goes Down in Cold Weather

If you feel like you haven’t been getting the best gas mileage since winter rolled in, you’re not crazy. You’re probably not sucking it all up using your heater either (though defrost might be another story). When cold weather rolls in, it automatically takes a chunk from your gas mileage, but a hidden culprit might be a sudden reduction in your tire pressure.

Using air valve caps that alert you when your tire pressure is low is a good way to keep tabs without having to check the pressure yourself all the time. And really, who wants to be in their knees, wrangling with tiny plastic parts like valve caps out in the snow? Once reset, you shouldn’t have to worry too often, though. It’s a good idea to recheck your pressure whenever there’s been a big chill.
