Technical Specifications

Product Structure

This heavy off-road tyre adopts ultra-reinforced composite construction, featuring thick multi-layer carcass, heavy-duty bead, multi thick steel belts, ultra-deep block tread with stone ejectors and extra thick anti-cut sidewall, offering outstanding load, anti-impact and anti-puncture performance for mine sites.

Applications

1.Open-pit & underground mine transportation

 For ore, waste rock and muck transport dump trucks in mines. Adapt to sharp rock, bumpy and muddy mine road surfaces, resist tread cutting and stone impact under continuous full-load operation.

2.Quarry & sand aggregate yard haulage

Suitable for sand, stone and aggregate delivery vehicles. The ultra-deep tread blocks provide strong grip on loose gravel slopes, while stone ejection design avoids tread cracking caused by trapped gravel.

3.Large-scale construction & earthmoving projects

Match engineering dump trucks for road construction, bridge foundation and land reclamation. Tolerate mixed muddy, broken concrete and debris construction roads with outstanding anti-puncture capability.

4.Mountain heavy cargo transportation

For heavy trucks transporting minerals, building materials in rugged mountain areas. Deep block tread ensures stable traction on steep, muddy mountain dirt roads during climbing and braking.

5.Municipal large-scale engineering operations

Applied to heavy sanitation dumpers and road maintenance engineering vehicles, coping with damaged urban construction roads mixed with stones and mud.

6.Remote wilderness material transportation

For material supply trucks in remote construction zones, oilfield mountain branches and rural unmaintained rugged roads.

FAQ

1.Q1:What is the main difference between off-road mine tyres and mixed on&off road tyres?

A: Mine off-road tyres adopt ultra-deep tread, thicker carcass and stronger anti-cut rubber compound. They focus on heavy-load anti-impact performance for pure rocky mine roads, while mixed service tyres balance highway wear resistance and basic off-road capability, not suitable for long-term severe mine working conditions.

2.Q2: Can this mine tyre run on paved highways for long-distance transport?

A: Not recommended. Its speed symbol is D with maximum speed limit of 65km/h. Long-time high-speed driving will lead to severe heat accumulation, abnormal wear and hidden safety hazards. It is only designed for low-speed short-distance transfer.

Q3: What does the "★" mark on the specification table mean?

A: It stands for reinforced heavy-duty version. Tyres marked with ★ have thicker carcass plies and strengthened bead structure, with higher load capacity and better anti-impact performance than standard tyres of the same size.

4.Q4: Why is the tread depth of 10.00R20~12.00R20 mine tyres up to 22-23mm?

A: Extra-deep block tread greatly extends service life under rock and gravel mine roads. It also provides powerful traction and effectively reduces tread chipping, tearing and stone trapping damage.

5.Q5: What is the load difference between 18PR and 20PR of 12.00R20 tyre?

A: 12.00R20 18PR★ load index is 154/151; 20PR★ is upgraded to 156/153. The 20PR model has thicker multi-layer carcass to bear heavier full-load continuous transportation in heavy mines.

6.Q6: What export certifications do these mine tyres have?

A: All specifications pass DOT, ECE, INMETRO, ISO and 3C certifications, meeting market access standards of mining machinery importers around the world.

7.Q7: How to maintain mine tyres to extend service life?

A: Keep standard tyre pressure, avoid overloading and sharp rock impact; clean stones trapped in tread grooves regularly; control driving speed below 65km/h; inspect sidewall scratches and tread damage every day before operation
