For instance, one an example of the Toyota Tundra we checked, the recommended tire pressure stood at 30 PSI, while both the Toyota Camry and RAV4 had recommended pressures of 35 PSI.

Published load and inflation tables from Goodyear and Michelin indicate 75 psi (80 psi by Bridgestone’s table) is the minimum pressure required to support a tire load of 4,550 pounds.

According to the US Environmental Protection agency, the average tire is underinflated by 1.8 PSI (1.1 PSI in front and 2.8 PSI in back), and for every pound of pressure too low, you lose 0.4% in ...

Proper tire inflation is important, and even more important on a motorcycle. Here's how you should inflate the tires on your Harley-Davidson.

Motorcycle tire performance is critical, and the air pressure of the tire is crucial. Some owner’s manuals or other information lists motorcycle tire air pressures in various units of measurement.

To get that minimum inflation pressure, Goodyear's tables recommend 105 psi for a tire load of 6,225 pounds. Bridgestone, on the other hand, calls for 110 psi for a maximum tire load of 6,175 pounds.

If your tire pressure warning light just came on, the culprit could be falling temperatures. Consumer Reports tells you what to do when that tire pressure warning light comes on.
