Tire Inflation and Load Limits

The factory installed wheels and tires are designed to handle loads up to and including their rated load capacity 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 should be checked monthly or before any extended trip and set to the specifications on the tire label. Check the pressure with the tires cold-after vehicle has not been driven for three hours or more, or driven less than 1.6 km (one mile).

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 kilopascal (kPa). Tire pressure may be printed in both kPa and pounds per square inch (psi). One psi equals 6.9 kPa.

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