Tire Inflation Description

This vehicle is equipped with a Tire Pressure Monitoring System.

This vehicle has been engineered to operate up to the stated load capacity with wheel and tire assemblies of the type, size, construction, and configuration as originally installed. Maintenance of the tire inflation pressures is critical to the continued satisfactory performance, handling, and operating economy of the vehicle. Operation with incorrectly or improperly inflated tires can adversely affect vehicle performance and may contribute to the following:

• Vehicle handling concerns
• Poor fuel economy
• Shortened tire life
• Tire overloading

Inspect the tire pressure when the following conditions apply:

• The vehicle has been sitting at least 3 hours.
• The vehicle has not been driven for more than 1.6 km (1 mi).
• The tires are cool.

Inspect the tires monthly or before any extended trip. Adjust the tire pressure to the specifications on the tire label. Install the valve caps or the extensions on the valves. The caps or the extensions keep out dust and water.

The Kilopascals (kPa) is the metric term for pressure. The tire pressure may be printed in both Kilopascals (kPa) and psi. One psi equals 6.9 kPa.

Tires with a higher than recommended pressure can cause the following conditions:

• A hard ride
• Tire bruising
• Rapid tread wear at the center of the tire

Tires with a lower than recommended pressure can cause the following conditions:

• A tire squeal on turns
• Hard steering
• Rapid wear and uneven wear on the edge of the tread
• Tire rim bruises and tire rim rupture
• Tire cord breakage
• High tire temperatures
• Reduced vehicle handling
• High fuel consumption
• Soft riding

Unequal pressure on the same axle can cause the following conditions:

• Uneven braking
• Steering lead
• Reduced vehicle handling

Refer to the Tire Placard for specific tire and wheel applications and tire pressures.
