Tires
Proper tire inflation pressure is essential to the safe and satisfactory operation of
your vehicle.
Tire inflation pressures are provided on your vehicle's "Tire Information Label"
(See page 38, Figure
Four (4) primary areas are affected by improper tire pressure:
1. Safety
Under-inflation increases tire flexing and can result in tire failure. Over-inflation
causes a tire to lose its ability to cushion shock. Objects on the road and potholes
could cause tire damage that may result in tire failure. Unequal tire pressure can
cause steering problems.
After inspecting or adjusting the tire pressure always reinstall the valve stem cap.
This will prevent moisture and dirt from entering the valve stem, which could
damage the valve stem.
2. Range
Improper inflation pressures can cause uneven wear patterns to develop across the
tire tread. These abnormal wear patterns will reduce tread life resulting in premature
replacement. Under-inflation increases tire rolling-resistance, resulting in lower
vehicle range.
3. Ride Comfort and Vehicle Stability
Proper tire inflation contributes to a comfortable ride. Over-inflation produces a
jarring and uncomfortable ride. Both under-inflation and over-inflation affect the
stability of the vehicle and can produce a feeling of sluggish response or over
responsiveness. Replace valve stem caps after tire maintenance to prevent dirt
from damaging valve stem or preventing the stem from closing properly.
4. Wear
Any accelerated wear of tires may be an indicator of improper alignment or
poor driving habits. If uncertain, consult your ACG service provider.
NOTE:
The vehicle's tire information can be found on the "Tire Information Label"
