Volkswagen Polo Service & Repair Manual: Wear Spots
| Wear spots are caused by a hard stop with locked wheels
whereby the rubber compound is abraded from the contact patch. |
| When the tires slide across the road surface, frictional
heat is generated which reduces the abrasion resistance on the
tread compound. |
| Even the most abrasion-resistant tread compound cannot
prevent wear spots which can occur during extreme braking. |
| Even ABS cannot completely prevent brief locking and the
resulting slightly flat spots. |
| The degree of abrasion is primarily dependent on the vehicle
speed, road surface and tire load. For clarification see the
following examples. |
| If a vehicle with locked front wheels is decelerated until
it comes to a stop, the abrasion of rubber on the post card
sized contact patch is approximately |
| from 57 km/h (35.41 mph) = 23.8 m braking distance, up to
2.0 mm, |
| from 75 km/h (46.60 mph) = 41.8 m braking distance, up to
3.3 mm, |
| from 92 km/h (57.16 mph) = 71.6 m braking distance, up to
4.8 mm. |
|
|
|
| Tires with this type of damage cannot be used and must be
replaced. |
