Features:
Superior Traction: Engineered with a high-grip pattern to deliver excellent driving power and slip resistance.
Exceptional Wear Resistance: Utilizes an advanced anti-wear compound to maximize tread life and minimize uneven wear.
Applications:
Optimized for medium-to-long-haul trucks operating on mixed road conditions, including both paved highways and unpaved regional terrains.
High Driving Power & Traction: The precision-engineered zig-zag tread grooves provide continuous biting edges, delivering superior driving force and reliable acceleration response on both dry and wet surfaces.
Excellent Wear Resistance & Long Tread Life: Formulated with an advanced anti-abrasion compound, the tread profile distributes footprint pressure evenly, preventing irregular shoulder wear (cupping) and maximizing original mileage.
Superb Hydroplaning & Stone Resistance: The deep vertical grooves efficiently channel water away to prevent hydroplaning, while the integrated stepped groove walls expel trapped gravel to protect the steel casing from stone drilling.
Premium Reinforced Casing for Retreadability: Built on a high-tensile steel belt structure, the robust carcass easily withstands heavy loads and road shocks, preserving the casing for multiple retread cycles.
Long-Distance Highway Logistics: Tailored for line-haul tractors and commercial fleets operating on well-paved national expressways at sustained speeds.
Regional Mixed-Road Transport: Highly reliable for regional distribution trucks navigating a combination of asphalt highways and well-maintained unpaved access roads.
Intercity Bus & Coach Lines: Provides the necessary low-noise comfort, steering precision, and braking security required for high-occupancy passenger transport.
Q1: Which wheel position is this pattern best suited for?
A: This is an All-Position tire, but it is highly recommended for Steer (Front) and Trailer axles. Its longitudinal rib design ensures excellent directional stability and resists lateral scrubbing.
Q2: Can this tire handle unpaved roads as shown in the specifications?
A: Yes. Unlike standard pure-highway slick ribbons, this pattern utilizes a robust zig-zag groove design that provides the necessary grip and stone-ejection required for mixed paved and unpaved regional routes.
Q3: How does this pattern contribute to fuel economy?
A: The continuous longitudinal rib layout reduces rolling resistance compared to heavy lug block patterns, allowing long-haul trucks to optimize fuel efficiency during constant highway speeds.
Q4: Is the casing sturdy enough for recapping?
A: Absolutely. The tire is manufactured with a premium 4-belt steel cord casing that offers superior structural integrity, allowing the tire to be retreaded 1-2 times under proper maintenance.
Industry 4.0 Smart Manufacturing: Produced in a fully automated smart facility with a capacity of over 6 million TBR units annually, guaranteeing bulk stock availability and prompt shipping.
Premium Materials: Built using high-grade natural rubber from specialized plantations in Thailand/Malaysia and world-class steel cords from Bekaert (Belgium).
Flawless Quality Control: Every single tire must pass a multi-stage inspection process, including 100% X-ray scanning, laser shearography, and dynamic balance uniformity testing.
Global Certifications: Fully certified and compliant with DOT, ECE, SMARTWAY, GCC, ISO9001, IATF16949, and INMETRO for smooth customs clearance worldwide.
We've Got You Covered: Performance & Durability Solution.
Market Challenges: African long-haul operations frequently face extreme tropical ground heat, heavy load stresses, and unpredictable route transitions from smooth asphalt to rough dirt tracks.
Our Dedicated Solution: * Thermal Dissipation Compounds: The tread rubber integrates heat-resistant polymers that mitigate internal heat accumulation during long midday journeys, preventing rubber degradation and heat blowouts.
Heavy Load Casing Integration: Available in higher ply ratings (12R22.5 20PR), utilizing reinforced steel beads to eliminate rim slippage and handle unexpected payloads safely.
All-Terrain Flexibility: The dual-purpose zig-zag grooves offer a smooth highway experience while preserving standard traction when traversing local unpaved infrastructure paths.
Market Challenges: While heavy dump trucks use deep lug tires inside the pit, support trucks, water tankers, and mineral transport fleets running on secondary gravel roads require high steering stability combined with puncture resistance.
Our Dedicated Solution:
High-Strength Stone Rejection: Built-in geometric stone ejectors prevent small, sharp mining stones from getting trapped in the tread, protecting the underlying steel belts from puncture.
Reinforced Tread Base Rubber: An extra layer of cut-and-chip resistant compound underneath the tread pattern absorbs stone impacts and blocks sharp slate from piercing the carcass.
Directional Grip Control: Provides maximum steering accuracy and prevents front-axle sliding on loose gravel or muddy surfaces within mining logistics zones.
Market Challenges: High fleet operation costs are driven primarily by rapid mileage consumption, fuel-inefficient tread designs, and premature tire replacement due to irregular shoulder wear.
Our Dedicated Solution:
Low Rolling Resistance Engineering: The three longitudinal ribs optimize kinetic energy transfer, lowering vehicle rolling resistance to deliver a 3% to 5% reduction in commercial fuel consumption.
Irregular Wear Protection: Computer-optimized casing footprint guarantees uniform contact pressure across the entire tread area, eliminating localized friction and ensuring a long, even tire lifecycle.
Casing Life Extension: Enterprise operators can lower their total cost-per-kilometer by taking advantage of the high-integrity steel casing, which easily accepts hot or cold retreading processes after the original tread life is spent.
