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.

Incorrect tire pressures, or under-inflated tires can cause handling problems, poor fuel economy, shortened tire life, and tire overloading.
Check tire pressure when tires are cool, or after the vehicle has sat for 3 hours or more, or been driven less than 1.6 km (1 mile). Check tires monthly or before any extended trip and set to the specifications on the tire label.

Install the valve caps or extensions 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 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 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.
