Volkswagen Polo Service & Repair Manual: Diagonal Washouts
| Diagonal wear spots on tires |
| Diagonal wear spots run at an angle of approximately 45°
with respect to the plane of circumference. |
| They usually occur once, but may also occur several times
along the tire circumference. |
| Wear spots appear almost exclusively on the non-tractive
tires, especially the rear left tire. There are vehicle models
where wear spots appear rounded, which are not a problem. The
effect is increased by high toe values. Toe values at the lower
tolerance limit of the specified value improve the wear pattern. |
| The tire component integration is often found in the area
with the most pronounced diagonal wear spots. |
| Wheels with toe-in roll with a slip angle even when the
vehicle is traveling straight ahead. This leads to diagonal
tension in the contact zone between tires/road surface. |
| Driving with reduced tire pressure will improve the wear
pattern. To prevent such wear patterns, the toe values of both
rear wheels should be the same and the specified tire pressure
should be maintained. |
| If wear spots are detected, mount the wheels on the tractive
axle if the wear spots are still in the initial stage. Deeper
wear spots are irreparable. |
| When a customer complains of “diagonal wear spots”, the toe
adjustment must be checked. If it is OK, the cause for the
diagonal wear spots is most likely in the tires. |
| Tires with diagonal wear spots which developed due to faulty
adjustment of the axle geometry are excluded from the warranty. |
