TOPTRUST OTR TIRE

Our E-4 and L-5 series utilize a proprietary high-density natural rubber compound mixed with premium carbon black. Tested in high-altitude environments (above 4,000 meters in the Andes), our tires show a 22% increase in cut resistance and prolong tire lifespan by 800 to 1,200 operating hours compared to standard tier-3 brands, effectively reducing CPH by 18-20%.

Our 27.00R49 E-4 series features an extra-deep tread of 65 mm to 72 mm, providing a 35% longer service life in aggressive copper and gold mine haul roads.

Engineered with a 100% smooth tread profile and a depth of 90 mm (250% deeper than L-3), eliminating lug tearing and ensuring 0% stone-trapping damage.

We offer customized TKPH configurations ranging from 180 to 450 TKPH. For hot coastal desert mines in northern Chile, a higher TKPH prevents inner liner thermal degradation at speeds up to 50 km/h.

Our high-ply bias tires feature up to 40-PR or 48-PR reinforced nylon casings, delivering a maximum load capacity of over 25,000 kg per tire at an inflation pressure of 7.25 bar.

High UV levels accelerate rubber aging by 40%. Our tires are formulated with special anti-ozonant and anti-aging compounds that extend rubber flexibility and prevent sidewall cracking for up to 5 years of outdoor exposure.

Designed with an open groove-to-rubber ratio of 45:55, allowing 100% self-cleaning action to prevent mud packing and ensure constant lateral traction on 15-degree muddy inclines.

Featuring a reinforced hexagonal bead core and an anti-slip bead wrap, allowing operations at low pressures down to 3.0 bar without risk of rim spinning under high torque.

Our 18.00-25 IND-5 tire incorporates a wide flat tread radius and a rigid sidewall insert, reducing lateral deflection by 28% and eliminating uneven shoulder wear under 45-ton static container loads.

Our 445/95R25 (16.00R25) crane tires are DOT and ECE certified, rated for high-speed highway transit up to 80 km/h with a single-tire load index of 174F (6,700 kg).

In medium-duty construction earthmoving, our L-3 bias tires deliver a proven service lifespan of 3,500 to 4,800 operating hours, backed by a 100% manufacturing defect warranty.

Optimized nesting packing allows up to 28 to 32 pieces of 23.5-25 bias tires per 40'HQ container, reducing cross-ocean freight costs per unit by 15%.

Maintaining a strict deviation within ±0.2 bar of the recommended cold inflation pressure (e.g., 7.0 bar for 24.00R35) extends the tire casing life by 15% and allows up to 2 times of successful retreading.
