Volkswagen Polo Service & Repair Manual: Wear Spots

Volkswagen Polo Service & Repair Manual / Whels, Tires, Whel Alignment / Tires, Evaluating / Wear Spots

A wear spot is a flat spot on the tread of the tires that can be caused by extreme braking maneuvers on subsurface such as asphalt.

At the same time a tire during the braking maneuver is rubbed at selective points which causes a tire imbalance.

The consequences of a wear spot is strong vibrations in the vehicle, which can lead to a worsening of the driving behavior and a higher noise generation.

In most cases the tire tends to lock up due to the larger running surface at this location even with a slightly reduced braking effect leading to an increase in the vibrations.

Only for low intensity wear spots can the vibrations disappear after a short time through further wear on the tire.

Caution

“Large” wear spots due to wheel lock are irreparable! Tires with such damage must be replaced.
