Volkswagen Polo Service & Repair Manual: Tires, Damage from Low Tire Pressure
| The most common causes of failure are small external damage,
a defective valve or a leaky rim due to corrosion or damage. |
|
|
|
| Separation of Carcass and Rubber |
| Strong heating due to driving with substantially
insufficient pressure led to overheating and subsequent
separation of carcass from rubber material
-arrows-. |
| The tire shown here was sporadically driven with tire
pressure insufficient for the load. Typical indications for this
are the circumferential abrasions in the area of the bead caused
by the rim flange and the discoloration. Small, furrowed folds
are visible along the inner sidewall. |
| When the tire rolls, strong shear forces develop between the
steel belt layers, especially at the ends of the belts. |
|
|
|
| Tires with Wide Furrows Along the Circumference in the Area
of the Bead |
| Wide furrows along the circumference in the area of the bead
-arrows- indicate that the tire was
driven with insufficient air pressure. |
| Driving a vehicle with insufficient tire pressure or
ignoring or not recognizing tire damage can have serious
consequences. |
| The tire can no longer withstand the forces developing
during travel. |
| The function of the tire is limited by the defects mentioned
above. The rubber compounds separate from one another, resulting
in partial separation of tire components up to complete
destruction. |
