The chart gives examples of the effect that ambient temperatures can have on the air pressure inside the tire chamber. This chart is approximate and does not take into consideration of the heat ...

Everyone knows that tires should be full of air to function, but how much air you should have in your tires – in other words, tire pressure – depends on many factors.

PSI stands for pounds per square inch, the unit of measurement for tire pressure. When you hear your mechanic say your right tire's at 30 PSI, it means that's how much air pressure it has.

You may be wondering how to know what pressure to inflate your tires. It turns out the solution is very simple, and we have some other tips for you as well.

Yokohama Rubber has begun practical testing of a technology that gauges air pressure from the sound made by tapping on a tire. The company announced that it has developed an experimental pressure ...

When you air down your off-roader's tires, they flatten out slightly. This increases the surface area of the tire that makes contact with the road. By increasing that contact patch, your tires ...
