Removal and Replacement
Tire Dismounting and Mounting
Removal Procedure
Danger:
To avoid any vehicle damage, serious personal injury or death when major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed and strap the vehicle to the hoist.
Warning: Refer to Safety Glasses Warning Safety Glasses Warning.
1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle Service and Repair.
2. Remove the tire and wheel assemblies from the vehicle. Refer to Tire and Wheel Removal and Installation Service and Repair.
Note: Use correct wheel attachment and tire mounting procedures. It takes up to 70 seconds for all of the air to completely exhaust from a large tire. Follow the correct procedures to avoid the tire to bend the wheel at the mounting surface, vibration and/or shimmy, or wheel cracking.
Note: Use a tire changing machine to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel.
Note: Protect clear coating on aluminium wheels with the tire changing equipment. Avoid corrosion and prevent the clear coating from peeling from the wheel.
3. Remove the valve cap.
Note: The valve core (1) is a single use part. It must be discarded after removal.
Note: If the tire is to be refitted note and record the relationship and orientation of the tire to the wheel.
4. Using a suitable tool remove the valve core (1) from the valve stem (2).
Discard the valve core.
Caution:
Damage to either the tire bead or the wheel mounting holes can result from the use of improper wheel attachment or tire mounting procedures. It takes up to 70 seconds for all of the air to completely exhaust from a large tire. Failure to follow the proper procedures could cause the tire changer to put enough force on the tire to bend the wheel at the mounting surface. Such damage may result in vibration and/or shimmy, and under severe usage lead to wheel cracking.
5. Deflate the tire completely.
Caution:
Use a tire changing machine in order to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result.
Caution:
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.
Note: If the tire is to be refitted note and record the relationship and orientation of the tire to the wheel.
6. Remove the tire from the wheel, using a tire changing machine.
7. Remove any rubber, light rust or corrosion from the wheel bead seats.
8. If fitted, remove the tire pressure indicator sensor, refer to Tire Pressure Indicator Sensor Replacement Service and Repair.
Installation Procedure
1. If fitted, install the tire pressure indicator sensor, refer to Tire Pressure Indicator Sensor Replacement Service and Repair.
Note: 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.
Note: Rim-clamp tire changes are recommended.
Note: If fitting the original tire maintain the original relationship and orientation of the tire to the wheel.
Note: If fitting an European manufactured tire align the WHITE dot on the tire 180 degrees from the mark on outer flange of wheel, or if there is no mark on the wheel, align WHITE dot 180 degrees from the low point of the wheel as measured with the dial indicator.
Note: If the tire is to be refitted note and record the relationship and orientation of the tire to the wheel.
Note: If fitting a Japanese manufactured tire and there is a YELLOW dot but not a RED dot use the rule for Australian tires. If there is a YELLOW and a RED dot, ignore the YELLOW dot and use the RED dot as per the rule for Australian tires.
2. Apply an approved Lubricant to the tire bead and the wheel rim.
3. Install the tire using a tire changing machine.
4. Install a NEW valve core (1) to the valve stem (2).
Warning
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. Over inflation may cause the bead to break and cause serious personal injury.
5. Inflate the tire until the bead snaps over the safety hump then inflate to the specified pressure. Refer to Tire Inflation Pressure Specifications [1][2]Specifications.
6. Install a valve cap to the valve stem.
7. Make sure that the locating rings are visible on both sides of the tire in order to verify that the tire bead is fully seated on the wheel.
8. Balance the tire and wheel assemblies. Refer to Tire and Wheel Balancing Tire and Wheel Balancing.
9. Install the tire and wheel assemblies. Refer to Tire and Wheel Removal and Installation Service and Repair.
10. Remove the safety stands.
11. Lower the vehicle.
