Refer to the tables on the following pages for specific tire and rim applications.
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. This increased pressure must not be reduced.
