Comments on: How to Check Tire Pressure

on 3/3/2008 I like it. 4 out of 5 stars!

on 11/19/2007 Hey I got an ad from an Auto dealer to replace my air in my tires with Nitrogen, now I have looked far and wide to find any reason to do this. They caim to Increases tire life
Improves fuel economy
Reduces the chance of the tire failure
Improves braking and handling

Reduces wheel corrosion
Reduces running tire temperature
Maintains proper tire pressure
Ok So does any one have any real information on this?

on 5/31/2007 "Unscrew the plastic cap on the air valve. Put it in your pocket so you don't lose it."

This may be a horrible idea unless your tires are so clean you can eat off of them. Why would dirty a pair of pants to keep them safe when you can just put it back on as soon as you inflate it. Not to mention if you lose them they cost $0.67 for 4 at any auto store or even Wal-mart/Target.

on 2/2/2007 Never rely on visual judgment on knowing your tire pressure, as it is often not accurate. Always use a properly calibrated tire pressure gauge, or simply go with the recommended interval of once a month to pump air into your tires. Drive safe.

on 6/30/2006 A tire is considered "cold" when it has sat for three hours and not driven over three miles. Air does expand when it gets warmer and the base tire pressure takes that into account.

However if it is 0 degrees today and I fill up my tires and it is 60 degrees tomorrow, they could be overfilled. The best advice is to check them cold after any major temperature change.

on 3/15/2006 It is important to make sure that you're not checking tire pressure under either temperature extremes. Living in Canada, I checked the tire pressure the other day (February) and found the tires to be low. Apparently I overfilled the tires as when they get warmer the air expands. So make sure when you are checking your tires it is done when it's warmer out or when the tires have been run for a while.
