Performance Features
- Tread Design: Features a wide, deep symmetric ribbed pattern with S-shaped siping to enhance all-weather traction and straight-line stability in both wet and dry conditions.
- Durability & Wear: Lateral multi-sipes in the straight ribs help reduce irregular wear, while integrated stone ejectors in the grooves prevent stone drilling to protect the casing for future retreading.
- Handling: The enlarged road contact patch ensures faster, more precise steering response and improves overall vehicle controllability.
- Wet Performance: Circumferential grooves effectively disperse water and slush to resist hydroplaning.
Usage Recommendations
- Primary Application: Best suited for regional haul, urban pickup/delivery, and highway transit.
- Axle Placement: While optimized for the steer axle, its all-position design allows it to be used on any axle if required for your specific fleet needs.
