Spare Tire: Service and Repair
The compact spare uses a narrow 4-inch wide rim. The wheel diameter is usually one inch larger than the road wheels.
Do not use standard tires or snow tires on a compact spare wheel or damage to the vehicle may result.
Caution: Refer to Tire Inflation Caution in Service Precautions.
Periodically check the inflation pressure of the compact spare and maintain this pressure at 415 kPa (60 psi). Use the present tire changing equipment and procedures to mount and dismount the compact tire from its wheel. As with other tires, the beads should completely seat at 275 kPa (40 psi). You may then safely inflate the spare tire to 415 kPa (60 psi).
