Tire Dismounting and Mounting: Installation
Approved safety glasses and gloves should be worn when performing this procedure to reduce the chance of personal injury.
- Apply mounting lubricant to the tire bead and the wheel. Adhesives, Fluids, Lubricants, and Sealers
- Use the tire changing machine to install the tire to the wheel following the manufacturer specific directions for the tire changing machine being used.
- Place the inner tire bead onto the wheel.
- Position the tire machine installation head to the inner tire bead so as it will operate without contacting the valve stem/TPM sensor.
- Using the tire changing machine, install the inner tire bead to the wheel.
- Position the tire machine installation head to the outer tire bead so as it will operate without contacting the valve stem/TPM sensor.
- Using the tire changing machine, install the outer tire bead to the wheel.
- Some run flat tires may require more than 275 kPa (40 psi) to seat the bead. In such a case, a tire safety cage (1) must be used. Consult the tire manufacturer for its individual repair policy.
- Inflate the tire until it passes the bead humps. Be sure that the valve core is not installed at this time.
- Install the valve core to the valve core stem.
- Inflate the tire to the specified pressure as stated on the tire placard.
- Install the tire and wheel assembly. Tire and Wheel Removal and Installation
- Remove the support and lower the vehicle.
When mounting the tires, use an approved tire mounting lubricant. DO NOT use silicon or corrosive base compounds to lubricate the tire bead and the wheel rim. A silicon base compound can cause the tire to slip on the rim. A corrosive type compound can cause tire or rim deterioration.
Rim-clamp touchless tire changers are recommended.
Failure to position valve stem in proper position while dismounting and mounting the tire may result in the TPM sensor to become damaged.
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.
