Advanced belt design reduces tire weight and minimizes energy loss, delivering lower rolling resistance for improved fuel efficiency.

Rubber-infused belt cords help protect steel components from moisture and corrosion, improving durability, casing life, and retreadability.

Designed to evenly distribute contact pressure across the tread surface, helping maintain a stable footprint under varying loads and driving conditions. This balanced pressure distribution encourages consistent wear patterns, reduces irregular abrasion, and supports improved mileage while preserving reliable handling throughout the tire’s service life.

The innovative three-belt package helps protect against turning forces while combating stress concentrations across the casing structure. This reinforced belt design supports consistent handling performance across irregular and uneven road surfaces, while promoting structural stability and durability under demanding fleet service conditions for extended wear life.

Reinforced bead construction paired with optimized rectangular steel wire geometry improves flexibility while ensuring secure, consistent bead seating throughout the casing life cycle. This design enhances durability under heavy loads, supports stable load transfer at the rim interface, and improves resistance to bead-area fatigue under demanding service conditions.

Larger-diameter spiral steel cables strengthen the belt package to better withstand heat, heavy loads, and repeated stress across on- and off-road applications. This design improves durability, helps resist structural fatigue, and supports longer tire mileage by maintaining casing durability and tread stability in varying service conditions.

The hexagonal bead wire geometry distributes pressure evenly along the wheel circumference, helping the bead hold the rim more securely and transfer torque more efficiently under load. This controlled load distribution reduces slippage, enhances bead-area durability, and helps preserve casing condition to support multiple retread cycles.

Prometeon’s patented high-silica dual-layer tread compound enhances wet grip while limiting internal friction within the tread to reduce heat buildup under heavy loads and sustained speeds. Controlled heat generation improves rolling efficiency and compound durability, while maintaining flexibility in colder temperatures for consistent traction across varying road conditions.

The innovative PRO Grip Environment compound, uniquely developed by Prometeon, is engineered to improve tire efficiency while maintaining dependable traction across varying service conditions. By reducing energy loss within the tread, this advanced formulation lowers rolling resistance, supports consistent performance, and helps reduce environmental impact through improved fuel efficiency and lower emissions.

Built on more than 100 years of tire research and investment, this casing is designed and developed from the ground up to meet strict Tier 1 standards, combining premium material compounds with a full-width casing structure engineered by Prometeon.
