Volkswagen Polo Service & Repair Manual: 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. |
