Tire Inflation and Load Limits

GENERAL INFORMATION
The factory installed wheels and tires are designed to handle loads up to and including their gross axle weight when inflated to the recommended inflation pressures.

Correct tire pressures, wheel alignment, and driving techniques have an important influence on tire life. Under-inflated tires can cause handling problems, poor fuel economy, shortened tire life, and tire overloading. Heavy cornering, excessive rapid acceleration, and heavy braking will increase tire wear.

Tire pressure, with tires cold (after vehicle has set for three hours or more, or driven less than one mile) should be checked monthly or before any extended trip and set to the specifications on the tire label.

Valve caps or extensions should be installed on the valves to keep out dust and water.

The metric term for tire inflation pressure is the kilo-pascal (kPa). Tire pressure may be printed in both kPa and psi. One psi equals 6.9 kPa.

Higher Than Recommended Pressure Can Cause:
- Hard ride.
- Tire bruising or carcass damage.
- Rapid tread wear at center of the tire.

Lower Than Recommended Pressure Can Cause:
- Tire squeal on turns.
- Hard steering.
- Rapid and uneven wear on the edge of the tread.
- Tire rim bruises and rupture.
- Tire cord breakage.
- High tire temperatures.
- Reduced handling.
- High fuel consumption.
- Soft ride.

Unequal Pressure On Same Axle Can Cause:
- Uneven braking.
- Steering lead.
- Reduced handling.
