Volkswagen Golf Service & Repair Manual: Wear in middle of tyre

This wear pattern is found on the driven wheels of high-performance vehicles that are frequently driven long distances at high speeds.
At high speeds, centrifugal forces cause the tyre diameter to increase more in the middle of the tread than it does at the shoulder. This causes drive forces to be transferred to the road surface from the centre section of the tread. This is reflected in the wear pattern.
Effects of this kind can be especially pronounced on wide tyres.
It is not possible to counter this wear pattern by reducing the tyre pressure.
  WARNING
For safety reasons, the tyre pressure must not under any circumstances be reduced below the specified tyre pressure.
A more or less even tread wear pattern can be achieved by interchanging the tyres on the driven wheels and non-driven wheels in good time.
   
Increased tread wear
The typical tread wear pattern of tyres run on the driven wheels of a high-performance vehicle.
The increased wear in the centre section of the tread results from the extra loading associated with centrifugal forces within the tyre and the transmission of drive forces.
