Checking Tire Pressure
WARNING
Explosion hazard
Over-inflation of tires may cause them to explode, which could
result in serious injury.
Do not inflate the tires above the maximum pressure.
Tire pressure should be checked periodically. Recommended
tire pressure varies by tire manufacturer. A good rule of thumb
is to inflate the tire up to, but not exceeding, the "Max Inflation"
stamped on the side-wall of the tire.
