Built on Sumitomo Rubber Industries' proprietary S-Tech Design platform and enhanced with 4D Nano Design technology, the ST948 SE delivers a proven combination of extended tread life, reduced rolling resistance, and dependable drive-axle performance that modern fleet operators demand.

Key Features:

• S-Tech Design with 4D Nano Technology — Proprietary engineering that maximizes original tread life while minimizing rolling resistance for superior fuel economy across the entire product line
• Extra-Deep 30/32nds Tread Depth — Closed-shoulder tread construction delivers exceptional mileage potential and extended service life, lowering cost per mile for long-haul fleets
• Wide Tread Blocks — Minimize tread squirm to reduce rolling resistance, promote long even treadwear, and increase miles to removal
• Wider Footprint — Distributes load over a larger, more consistent contact patch for improved stability, even wear, and greater load-carrying capacity
• Micro-Sipes — Enhance traction across varied road and weather conditions, including wet and wintry surfaces, while dispersing water from the contact patch
• Stone Ejectors — Integrated at the base of the shoulder grooves to resist stone drilling and protect casing integrity over the long haul
• EPA SmartWay Verified — Certified for low rolling resistance and enhanced fuel efficiency, helping fleets meet environmental compliance standards and reduce operating costs
• Retread-Friendly Casing — Robust casing architecture built for retreadability, maximizing total tire lifecycle value for cost-conscious fleet managers
