Patent No. EP4311690 (titled "Rubber Composition For A Truck Tire") was filed by The Goodyear Tire & Rubber on Jul 27, 2023. The application was issued on May 21, 2025.
A rubber composition for truck tires that balances rolling resistance and wet traction while maintaining limited abrasion. The composition comprises 70-95 phr polyisoprene, 5-30 phr solution-polymerized styrene-butadiene rubber with a glass transition temperature below -40°C, and 40-80 phr silica filler. The rubber composition is particularly suited for truck tires, including semi-trailer trucks, where improved rolling resistance and wet traction are critical.
