The Grandtour utilizes an asymmetric tread design with three center ribs that optimize surface contact for responsive steering and high-speed stability up to V (149 mph), while dense siping boosts wet adhesion by channeling water effectively. The silica-infused compound reduces rolling resistance for improved fuel economy and resists heat buildup for consistent dry handling. Variable pitch sequencing and vibration-absorbing blocks minimize road noise and impacts for a serene ride, with reinforced construction promoting uniform wear and durability under varying loads up to 750 kg.
