BackgroundAlongside standard mining trucks, the same central African mining operations run wide-body dump trucks for ore haulage. Since 2025, XINGXI has supplied OTR tires in 14.00R25 and 16.00R25 for these heavy-duty vehicles across the DRC and Zambia metal mining sites.

The Challenge

• Wide-body trucks operate at very high gross weights, demanding tires with strong carcass and cut-resistant tread

• Metal ore surfaces create sharp, abrasive conditions that quickly destroy standard tread patterns

• High ambient temperatures shorten tire life and raise the risk of heat-related failure

• OTR tires are high-value assets — any wrong spec or pattern match is a costly mistake

How XINGXI Responded

• Selected deep, cut-resistant OTR patterns suitable for metal mining and heavy haulage

• Matched 14.00R25 and 16.00R25 specs to the specific truck models and axle positions

• Verified load capacity and speed requirements against actual operating conditions before recommending the final spec

• Coordinated delivery timing with the fleet's mine operation schedule to avoid equipment downtime

The Result

• Both specs performed well in service under harsh mining conditions

• Tire consumption and damage were controlled at acceptable levels for the operating environment

• The customer expanded tire procurement with XINGXI as the mining operation scaled up

Key Facts

• Specs: 14.00R25 / 16.00R25 OTR tires for wide-body dump trucks

• Application: metal mine haulage, high-temperature environment

• Outcome: strong performance, expanded cooperation
