How do you tell if I have a flat tire?

Answer by  69nova (389)

Being able to tell if your tire is flat should be fairly simple. The side wall of the tire will be collapsed. Also you can just compare it with your other tires,and check the air pressure difference with a tire gauge.

Well the most obvious thing to do is look at it. Does it look flat or very under inflated. The best thing to do is check the tire pressure with a gauge and compare that to what it should be. If it is low, add some air to it until it is at the recommended psi.
