Triangle 40.00R57 Giant OTR Tires on Komatsu 830E Mining Trucks Surpass 120,000 Kilometers

Recently, at a massive mining in Inner Mongolia, a rigorous “performance examination” for high-end giant OTR tires performance outstanding results. Triangle 40.00R57 TB599A PRO giant OTR tires operated continuously for over 10,000 hours under severe working conditions, covering a distance exceeding 120,000 kilometers. This achievement shattered the existing operational record for giant OTR tires of the same model in hard-rock mining environments, marking a significant milestone in elevating the competitiveness of China produced giant OTR tires within the high-end mining transportation sector.

Triangle 40.00R57 TB599A PRO giant OTR tires on Komatsu 830E from 2023 to 2026

Reportedly, this record-breaking Triangle giant OTR tire 40.00R57 was fitted to a Komatsu 830E a mainstay of the mining truck fleet in December 2023. Over a period spanning more than two years, it withstood the continuous and rigorous demands of the Inner Mongolian mine’s complex terrain. The mining roads characterized by their ruggedness, loose gravel, and steep gradients, which are an extreme challenge to the giant OTR tire’s wear resistance, impact resistance, and load-bearing capacity. When the tire was finally removed from service in March 2026, it had accumulated a total operating time of 10,298 hours and covered a distance of 123,000 kilometers, thereby substantiating its outstanding performance and reliability through concrete data.
