Volkswagen Polo Service & Repair Manual: Tire Wear, Center
This wear pattern is found on drive wheels on high-powered
vehicles that often drive long stretches at high speed. |
At high speeds, the centrifugal force increases the tire
diameter at the center of the tread more than at the shoulders
of the tire. The drive forces from the center area of the tread
are transferred to the road surface. This is reflected in the
wear pattern. |
These effects can appear especially extreme on wide tires. |
Reducing the Tire Pressure is Not an Effective Remedy for
this Wear Pattern. |
WARNING
For safety reasons, tire pressure must never be
lowered below specified pressure under any
circumstances. |
|
A largely even wear pattern can be achieved if tires are
changed in a timely manner from the tractive to the non-tractive
axle. |

|
|
Typical wear pattern of tires on the tractive axle of
high-powered vehicles. |
The increased wear at the tread center is caused by stresses
related to the centrifugal force of the tire and the
transmission of traction forces. |
