Hauptursachen für Reifenschäden

Reifenschäden werden oft durch einfache, leicht vermeidbare Bedienungsfehler verursacht. Die Aufrechterhaltung des richtigen Luftdrucks (1) mit der entsprechenden Wärmeentwicklung (2) im Reifen ist der wichtigste Schritt zu einer längeren Lebensdauer des Reifens. Selbstverständlich ist auch eine regelmäßige Fahrzeugwartung (3) und die Auswahl des richtigen Reifens für die jeweilige Anwendung (4) zur Gewährleistung niedriger Kosten pro Kilometer maßgebend.

1 – Inflation Pressure

The weight of the load is carried by the air within the tyre, not the tyre itself. Maintaining the correct inflation pressure is absolutely necessary to guarantee the tyre’s performance. Pressure should always be set to, and maintained at the maximum load- / -pressure specification recommended by the tyre manufacturer.

COMMON MISTAKES

Under inflation causes excessive deflection in the tyre, increasing the heat level and leading to premature tyre failure.
Over inflation restricts the natural deflection of the tyre, leading to premature tyre failure.

Solutions

Check the appropriate maximum load- / -pressure ratio of a tyre and then calculate the best combination for your use. A lower inflation pressure limits load capacity.
Pressure should be checked at regular intervals.
Underinflation and over inflation should be avoided.

2 – Heat build up

Heat is the tyre’s worst enemy and is caused by several factors. As a tyre rotates under the weight of a vehicle and its load,
it repeatedly deforms and recovers, which generates lots of energy. When this energy is released, heat builds up, making
it more susceptible to wear, cuts and structural fatigue. The amount of heat build-up is determined by several factors
including:

Under-inflation
Overloading
High speeds
Harsh breaking
Aggressive cornering
Poorly designed or badly maintained roads
Working outside tyre specs
Seasonal influences

All these factors contribute to an increased deformation / recovery process, generating more energy
and heat build-up resulting in a reduced tyre lifetime.

Common mistakes (Heat build up)

Under-inflation and Over –inflation
Exceeding the load capacity of a tyre
Driving at a higher speed than the designated load / speed capacity
Non-professional driving style, with harsh breaking and aggressive cornering
Neglected road maintenance
Poor design of the road, for example, the road is too steep
Not taking into consideration seasonal effects

Solution (Heat build up)

Underinflation and over-inflation should be avoided
Ensure the vehicle carries no more than the appropriate load capacity and drives at the corresponding speed
Gradients in the road shouldn’t exceed 5%-6% and should be maintained regularly
Always maintain a professional driving style to ensure a prolonged tyre life

3 – Vehicle Maintenance

Finally, vehicle maintenance is another important factor for an efficient use. The machine’s performance can cause severe
damage to its tyres. Neglecting regular vehicle maintenance can severely reduce tyre life and increase its running cost.

Common mistakes

Misalignment causing tread separation, increased and- / -or irregular tread wear, tyre vibration
Broken suspension, increased and- / -or irregular tread wear
Fuel and oil leaks damage to the rubber compound which shortens tyre life
