The winter is an especially important time to check your air pressure regularly. Fluctuations in temperature quickly deflate tires over time, which makes more frequent air fill-ups necessary. As a rule, you should be checking your tire pressure every time you fill up your gas tank. You may have heard that for every 10 degree increase or decrease in temperature, the PSI in your tires falls or rises by 1. Over time this significantly affects the air pressure in your tires and can override any performance, mileage, or safety characteristics your tires would normally provide.
Nitrogen Gas For Tires
Is there anything you can do to stop air from leaking out during wintry temperature fluctuations? Many drivers believe that switching to nitrogen instead of compressed air can help. Unlike the oxygen molecules in compressed air, nitrogen molecules are large and don't leak out of the tire as easily. This results in tire pressure that stays constant three to four times longer than a tire filled with compressed air.
Does Filling My Tires With Nitrogen Really Help?
Will filling your tires with nitrogen really make a difference this winter? Sure it will, but it is NO SUBSTITUTE for routine air checks. Nitrogen will still leak out eventually, but it will last longer than you're used to. Don't get a false sense of security and fill your tires with nitrogen and then forget about them all winter. If you've been following the rule of checking your tire pressure each time you fill up your tank, you can now extend that rule to every other time you fill up the tank.
Only certain locations provide nitrogen fills, so be sure to call ahead to your local auto shop to see if they provide this service as it grows in popularity.
