They provide additional biting edges to offer a safer braking capability by allowing a shortened braking distance. The better braking ensures a secure drive. The five-rib symmetric tread design also boosts the steering responsiveness and the driving stability. The maintained road contact guarantees stability against the driving pressure affecting the tire, while the it promotes a quick and precise steering response to the driver's commands. The combination of the increased braking ability, steering responsiveness and precision and the driving stability improves the tire's all weather handling and controllability.
