Centre wear
Centre wear
   
This type of wear is typical on the drive-wheels of powerful vehicles, frequently used on long journeys at high speeds.
Due to centrifugal forces, when driving at high speeds the tyre diameter is more pronounced in the centre of the band than at the shoulder. The driving force is transmitted from the central part of the band to the road, and this is reflected in the pattern of wear on the tyre.
This effect is particularly noticeable on wide tyres.
This pattern of wear can not be reduced by deflating the tyres.
  WARNING
For reasons of safety, tyres must never be deflated to below the specified pressure values.
More uniform wear can be obtained by regularly interchanging the tyres on the drive-wheels to the other axle.

High wear on the tread band
Typical wear pattern on drive-wheels of a powerful vehicle.
The high level of wear on the central part of the tread band is due to the effort related to the centrifugal force of the tyre and the transmission of the drive wheel.
