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

  the passage

  Wheel slip normally occurs for the following reasons: • Excessive amount of lubricant used or lubricant applied in the wrong locations.

• Improper, non-preferred or improperly diluted lubricants may contain excessive moisture or components that do not dry sufficiently, leaving the tire-to-rim interface excessively slippery.

  the passage

  Improper lubricants, non-preferred lubricants or improperly diluted lubricants may contain excessive moisture or components that do not dry sufficiently, resulting in an interface between the tire and rim that is excessively slippery.

Steps to confirm (in the document’s order)

1. Wheel slip can be checked by placing a temporary mark on the tire at the valve stem.
