In the mining and construction industries, tyres are more than just a component of heavy equipment — they are a critical investment. Off-The-Road (OTR) tyres carry enormous loads, withstand extreme terrains and directly impact operational efficiency and profitability. Selecting the right OTR tyre goes beyond size; it requires understanding performance, safety and long-term cost-effectiveness.
1. What Are OTR Tyres?
OTR tyres are engineered for large machinery such as dump trucks, wheel loaders, graders and cranes used in mining, construction and quarrying. Unlike standard tyres, OTR tyres must handle intense weight, abrasive conditions and irregular terrains while delivering durability and performance.
2. The Key Factors to Consider When Choosing OTR Tyres
a. Application & Terrain
Different terrains demand different tread designs:
- Rocky terrain – Deeper tread, cut-resistant compounds.
- Soft soil – Wider footprint for flotation.
- Mixed use – Balanced tread for versatility.
b. Load Capacity
Every OTR tyre has a load index that specifies its safe carrying capacity. Overloading can lead to catastrophic tyre failure and costly downtime.
c. Compound & Tread Design
The tyre compound determines resistance to cuts, heat, and wear:
- Mining – Cut resistance is key.
- Construction – Heat resistance is essential for long hauls.
d. Radial vs. Bias Construction
- Radial OTR tyres – Longer tread life, better traction, improved heat dissipation.
- Bias OTR tyres – Lower upfront cost, stronger sidewalls for extreme short-haul loads.
3. The Cost vs. Value Equation
OTR tyres represent a significant share of equipment operating costs. Choosing the cheapest option may lead to higher downtime costs. The smarter approach is to evaluate cost per hour or cost per ton hauled, ensuring long-term ROI.
4. Maintenance is Non-Negotiable
Even the most advanced OTR tyres fail without proper care. Essential practices include:
- Regular inflation pressure checks
- Scheduled rotations for even wear
- Avoiding unnecessary spinning or harsh braking
- Training operators in tyre-friendly driving
5. Why Partnering with the Right Supplier Matters
The right tyre supplier does more than deliver tyres — they provide expertise, technical support, and insights that extend tyre life and enhance fleet efficiency. For mining and construction companies, partnering with a specialist supplier ensures tyres are matched to site conditions and operational goals.
Final Thought
OTR tyres are not just an operational necessity — they are a strategic asset. By choosing the right type, ensuring proper maintenance, and working with an experienced supplier, mining and construction companies can reduce downtime, optimize performance, and protect profitability.
