Tyre Dismounting and Mounting

Caution: Use a tyre changing machine in order to dismount tyres. Do not use hand tools or tyre levers alone in order to remove the tyre from the wheel. Damage to the tyre beads or the wheel rim could result.

Caution: Do not scratch or damage the clear coating on aluminium wheels with the tyre changing equipment. Scratching the clear coating could cause the aluminium wheel to corrode and the clear coating to peel from the wheel.

    Caution: Damage to either the tyre bead or the wheel mounting holes can result from the use of improper wheel attachment or tyre mounting procedures. It takes up to 70 seconds for all of the air to completely exhaust from a large tyre. Failure to follow the proper procedures could cause the tyre changer to put enough force on the tyre 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.

  1. Deflate the tyre completely.

    2. Note: Rim-clamp European-type tyre changers are recommended.

  2. Use the tyre changer in order to remove the tyre from the wheel.
  3. Use a wire brush or coarse steel wool in order to remove any rubber, light rust or corrosion from the wheel bead seats.

    4. Caution: When mounting the tyres, use an approved tyre mounting lubricant. DO NOT use silicon or corrosive base compounds to lubricate the tyre bead and the wheel rim. A silicon base compound can cause the tyre to slip on the rim. A corrosive type compound can cause tyre or rim deterioration.

  4. Apply an approved Lubricant to the tyre bead and the wheel rim.
  5. Use the tyre changer in order to install the tyre to the wheel.

    6. Warning: To avoid serious personal injury, do not stand over tyre 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 tyre 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.

  6. Inflate the tyre to the proper air pressure.
  7. Ensure that the locating rings are visible on both sides of the tyre in order to verify that the tyre bead is fully seated on the wheel.
