• Vibration shortly after tires are mounted may be caused by the tires slipping on the wheels, which moves the imbalance point of the tire away from the weight location.

  the passage

  A customer concern of vibration shortly after having a tire or tires mounted may be caused by slippage of the tires on the wheels, placing the imbalance point of the tire away from the weight location.

Possible causes

• Wheel slip is most common on clear coated or chrome wheels with very smooth bead seat areas, but may also occur on other alloy or steel wheels.

  the passage

  Wheel slip is most common on clear coated or chrome wheels with very smooth bead seat areas, but may also occur on other alloy or steel wheels.

• It normally occurs when an excessive amount of lubricant is used or lubricant is applied in the wrong locations.

  the passage

  Excessive amount of lubricant used or lubricant applied in the wrong locations.

Steps to confirm (in the document’s order)

1. Place a temporary mark on the tire at the valve stem and drive; if the slip is less than one inch, wheel slip is probably not contributing to the ride disturbance.

   the passage

   Wheel slip can be checked by placing a temporary mark on the tire at the valve stem. After driving the vehicle, if the wheel slip is less than one inch, then wheel slip is probably not contributing to a ride disturbance.

2. If the slip is greater than one inch and a ride disturbance was felt on the test drive, wheel slip may be causing the vibration.

   the passage

   When wheel slip is greater than one inch, and you felt a ride disturbance on the test drive, then wheel slip may be causing the vibration.

Repair

1. Clean the bead seat areas of the wheel of any lubricant left over from demounting the tire.

   the passage

   2. Clean the bead seat areas of the wheel of any leftover lubricant used to demount the tire.

2. On the wheel, lubricate the safety humps, leave the rim flanges dry, and lubricate the drop center area only for difficult to mount tires.

   the passage

   When lubricating the wheel, lubricate the safety humps, leave the rim flanges dry and lubricate the drop center area only for difficult to mount tires.

3. Complete the mounting within 10 minutes of applying the mounting lubricant.

   the passage

   7. The mounting process must be completed within 10 minutes of the application of the mounting lubricant.

4. Inflate the tires to 275 kPa (40 psi) when mounting, then reduce to the desired operating pressure.

   the passage

   8. Inflate the tires to 275 kPa (40 psi) when mounting, then reduce the air pressure to the desired operating pressure.

Caution

• Do not use products containing silicone, alcohol, petroleum based products, solvents or corrosives for cleaning or lubrication.

  the passage

  4. Do not use products containing silicone, alcohol, petroleum based products, solvents or corrosives for cleaning or lubrication.

• Do not drive the vehicle aggressively (hard acceleration or braking) for up to 24 hours after tire mounting, so the lubricant can dry.

  the passage

  Also, the vehicle should not be driven aggressively (hard acceleration or braking) for up to 24 hours after tire mounting to allow the lubricant to dry.
