Volkswagen Polo Service & Repair Manual: Cracking
| Cracking is the term for shallow cracks in the sidewall of
the tire. |
| They run starting from the bulge in the direction of the
tire shoulder. See Illustration for the mentioned components.
Refer to
→ Fig. „“Components of a Tire”“. |
| The cause is the increase in material at the joints of the
tire components. |
| Cracking has no effect on |
| Other characteristics of the tire. |
| Cracks can be of varying visibility. Removing the tire from
the rim or an examination is not necessary. |
| Modern steel belted tires are constructed with single-ply
sidewalls to save weight. |
| The sidewall components consist of long strips before they
are joined together to form a tire. They must overlap at the
joints. Small irregularities/ripples form in the area of the
overlapping components. The overlaps are easier to see from the
outside due to the single-ply construction. |
