For 1990-2009 cars

Caution: To avoid serious personal injury, do not stand over tire when inflating. The bead may break when the bead snaps over the 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, relubricate the beads and reinflate. Overinflation may cause the bead to break and cause serious personal injury.

Important: Do not lubricate the tire beads or wheel rim with the lubricant containing silicone. Silicone will allow the tire to rotate on the wheel rim, throwing the tire and wheel out of balance.

Clean the rim bead seats with a wire brush or a coarse steel wool to remove old rubber and light rust or corrosion. Before mounting or dismounting a tire, the bead area should be well-lubricated with GM P/N 9985555 (50% lubricant and 50% water) or equivalent.

Always refer to the tire manufacturer's mounting information and recommendations when mounting tires. The tires on this vehicle are asymmetric. The tires must be mounted on the rim with a designated side facing outward. Refer to the markings on tire sidewall for the designated side.

Use a tire changing machine to mount the tires or to dismount the tires. Follow the equipment manufacturer's instructions for mounting and for dismounting the tires. Do not use hand tools or tire irons to change a tire. A hand tool or a tire iron may damage the tire beads, may damage the wheel rim, or may damage the flanges.

Install the valve stem. Inflate the tire to the pressure specified on the tire placard. Check the locating rings of the tire and wheel to be sure they show around the rim flanges on both sides of the tire and wheel assembly.
