Inflation pressure should be checked when tires are cool, using an accurate tire pressure
gauge. Check pressures at regular intervals.
Bleeding the air from hot tires is dangerous and should not be attempted. While the
pressure will be reduced, an increase in temperature of the tire will take place as soon as
driving is resumed and tire failure will result.
UNDERINFLATION
Too little air pressure increases deflection, causes the tread to wipe and scuff over the
road, results in extra strain on the tire, and increases the chance for bruising.
PROPER INFLATION
Maintaining the proper air pressure provides maximum road contact and results in
increased tire life.
OVERINFLATION
Overinflation reduces tire deflection and tire contact area, causing the tire to ride on the
crown, and results in rapid wear in the center of the tread.
