Super Deep Tread L-5 OTR Tire for Extreme Mining & Quarry Operations
The KOYOOTO L-5 is a heavy-duty, extra-deep tread OTR tire engineered specifically for wheel loaders, dozers, and underground mining equipment operating in severe rock, quarry, and abrasive environments. Featuring a 250% deeper tread pattern than standard L-3 tires, the L-5 delivers unparalleled cut resistance, maximum tread wear life, and superior sidewall protection against sharp rock impacts.
Key Performance Advantages
- 250% Super Deep Tread: Massive tread depth provides maximum wear life and minimal cost-per-hour in harsh rock and mining sites.
- Premium Cut-Resistant Compound: Specialized rubber formulation guards against punctures, severe impacts, and tread tearing from sharp granite and iron ore.
- Reinforced Heavy-Duty Sidewall: Thickened shoulder and sidewall protection prevents costly side impacts and blowout hazards in underground pits.
- Optimized Contact Footprint: Flat, broad tread footprint distributes heavy payload evenly to improve machine stability and operator traction.
