For 1990-2009 cars

All vehicles will be equipped with a high pressure compact spare. The compact spare uses a narrow 4-inch wide rim, although the wheel diameter is usually 1 inch larger than the road wheels.

The compact spare wheel should not be used with standard tires, snow tires, wheel covers or trim rings. If such use is attempted, damage to these items or other parts of the vehicle may occur. Only use the compact spare on vehicles which offered the spare as original equipment.

Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when bead snaps over safety hump. Do not exceed 275 kPa (40 psi) pressure when inflating any tire if beads are not seated. If 275 kPa (40 psi) pressure will not seat the beads, deflate, lubricate the beads and reinflate. Overinflation may cause the bead to break and cause serious personal injury.

Inflation pressure of the compact spare must be periodically checked and maintained at 415 kPa (60 psi). It may be mounted and dismounted from its wheel using present tire changing equipment and procedures. As with other tires, the beads should completely seat at 275 kPa (40 psi). The tire may then be safely inflated to 415 kPa (60 psi).
