ZC Rubber showcased its latest OTR innovations at Bauma 2025, held in Munich on April 7–13. The company unveiled new OTR tire products from premium brands Westlake and Tianli, designed to meet the needs of demanding off-road applications with enhanced performance, durability and versatility.
Westlake debuted the 29.5R25 CB740 tire, specifically designed for articulated dump trucks. Featuring a robust block tread design, the tire offers enhanced ground contact and stability and superior resistance to punctures and wear. The tread depth has been increased by 17% compared to the TRA standard E-4 pattern, effectively extending the tire’s service life. Additionally, the multi-compound design adapts to various operating conditions, while the upgraded sidewall compound boosts puncture resistance by 10% and reduces crack propagation by 15%.
Westlake also presented the 35/65R33 CB398 for underground mining trucks and the 290/90-20 EL08 for wheel excavators.
Tianli revealed the new 800/45-30.5 Forest Grip tire, which features an open tread design that significantly enhances self-cleaning capability. Primarily designed for forestry equipment, its tread structure evenly distributes engine power across the contact surface, reducing slippage and maximizing power efficiency. It is also well-suited for articulated dump trucks operating in challenging off-road conditions.
Tianli also highlighted the 460/70R24 Backtrack Radial Supreme, a radial tire designed for agricultural machinery such as backhoes and telehandlers. With a robust tread base design, it offers high levels of traction and wear resistance. The reinforced shoulder design improves stability and puncture resistance, making it well-suited for demanding environments.
