Kumho KMA01 Commercial Truck & Bus Tire - On/Off Highway Mixed Service

The Kumho KMA01 is a medium-duty commercial truck and bus tire purpose-built for steer and trailer axle positions in demanding on/off highway mixed-service applications. Engineered to maximize uptime and long-term cost efficiency for fleet operators, the KMA01 combines proven radial tire technology with a strong focus on durability, retreadability, and dependable all-conditions performance across a wide range of operating environments.

Key Features:

• Cut and Chip Resistant Compound: A specially formulated tread compound resists cutting and chipping, extending removal mileage in mixed on/off-road service conditions

• Advanced Steel Belt Package: Reinforced belt structure enhances casing integrity and uniformity, supporting superior retreadability and extending the overall service life of the casing
• Groove Bottom Protectors: Prevent stone drilling and stone retention, reducing the risk of casing damage and preserving retread potential throughout the tire's full service life
• Superior Bead Strength and Tire Uniformity: Promotes even wear distribution and enhanced casing durability, improving driving stability across the full service cycle
• Four-Rib Tread Design: Delivers superb handling, minimal rolling resistance, and consistent performance across both highway and off-road segments
• Wet Weather Performance: Circumferential grooves expel water to reduce hydroplaning risk, while sipes improve grip in wet and variable road conditions

Its robust construction and retread-friendly casing design make it a cost-effective solution for fleet managers operating where both highway efficiency and off-road durability are essential.
