Tyre Damage Causes

Tyre damage is often caused by simple, easily avoidable user errors. Maintaining the right inflation pressure (1), with the appropriate heat build-up (2) within the tyre is the most important step to a prolonged tyre life. Of course regular vehicle maintenance (3) and selecting the right tyre for the appropriate application (4) is also necessary to ensure low costs per mile.

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.
Under inflation 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)

Under inflation 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

Solution

Always ensure regular vehicle maintenance

4. Selecting the right tyre

Selecting the right tread pattern will extend the tyre life significantly. Your Magna Tyres representative can assist you by making this selection.

Tread Pattern – The tread pattern is designed to produce varying degrees of traction, cut, flotation, wear and heat resistance.
Tyre Construction – Radial – Bias – Solid construction offer various advantages and disadvantages according you specific applications.
Compound & TKPH – Compound and TKPH determines tyre life can affect the lifespan of a tyre.
Load- Speed Index – operate at the proper loading capacity.
