BackgroundSince 2025, XINGXI has been supplying all-steel radial (TBR) mining tires to a transport fleet operating in the southern DRC (Lubumbashi region) and neighboring Zambia. The fleet handles copper mine haulage — metal mining sites with harsh road conditions, high ambient temperatures, and heavy tire consumption.

The Challenge

• Vehicles run at 50–60 tons gross weight on soft ore terrain, around 20 km per haul cycle

• High temperatures and abrasive surfaces accelerate wear and damage

• A previous batch from one factory had shown sidewall bulges caused by irregular steel cord spacing during mass production — a problem that appeared before the vehicles even entered mine service

How XINGXI Responded

• Recommended a mixed pattern setup: mining patterns on drive axles, rib/traction patterns on steer axles — matched to the soft-ore, heavy-load scenario

• Supplied 1200R20 and 1100R20 mining tires in the quantities required for a growing fleet

• Established batch traceability and pre-shipment inspection after the earlier quality incident, ensuring any irregularity is caught before dispatch

• Worked with the factory on a fast claim process to protect the customer relationship and keep the project moving

The Result

• Through 2025, the tires performed well overall in service

• The fleet has continued procurement with XINGXI, confirming the reliability of the supply chain after the quality-control improvements

• The earlier incident became the basis for a stricter inspection system that now benefits all mining fleet customers

Key Facts

• Specs: 1200R20 / 1100R20 all-steel mining tires

• Application: 50–60 ton copper mine haulage, ~20 km cycles

• Outcome: stable performance, continued cooperation
