The fine grooves distributed on the surface of the tire and the numerous fine grooves on the edges of the tread grooves effectively accelerate the heat dissipation during tire driving and reduce tire damage.Adopting the latest shoulder cooling technology, optimized rubber formula combination for the shoulder area , improving heat dissipation capability , reducing tire operating temperature, and safer driving.The bottom of the groove is designed with bouncing stones to reduce stone cuts and cracks which can cause water seepage and rust on the steel cord, achieving optimal tire service life.
