Tire Pressures
General
Tires represent a safety element; they cannot fulfill the requirements placed on them unless the inflation pressures are correct and tread depth is adequate.
The pressures stated below are minimum values; under no circumstances should the pressures be allowed to drop beneath these levels, as this would add
the risk of serious tire damage and reduced directional stability.
Valve caps protect the valves from dust and dirt and thus from leaks. Always screw caps on tightly, replace missing caps.
For reasons of safety, the checking of tire pressure should be accompanied by a visual inspection to ensure adequate tread depth and a check for objects
piercing the tire, holes, cuts, cracks and bulges in the sidewall.
Measure tire pressure only when the tires are cold. Air pressure increases as the tires get hotter.
