When you inflate the tires to the recommended inflation pressures, the factory-installed wheels and tires are designed in order to handle loads to the tire's rated load capacity. Incorrect tire pressures, or under-inflated tires, can cause the following conditions:
Inspect the tire pressure when the following conditions apply:
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 kilopascal (kPa) is the metric term for pressure. The tire pressure may be printed in both kilopascal (kPa) and psi. One psi equals 6.9 kPa.

Tires with a higher than recommended pressure can cause the following conditions:
Tires with a lower than recommended pressure can cause the following conditions:
Unequal pressure on the same axle can cause the following conditions:
Refer to the Tire Placard for specific tire and wheel applications and tire pressures.
Child Restraint Systems
Rear-Facing Infant Seat
A rear-facing infant seat provides restraint with the seating surface against
the back of the infant.
The harness system holds the infant in place and, in a crash, acts to keep the
infant positioned in the restraint.
Forward-Facing Child Seat
A forward-facing chil ...
