The ST01 by Fortune features an optimized groove and profile design that amplifies load carrying capacity. An all season compound molds into a symmetric ribbed tread pattern that improves all season grip and controllability. Continuous ribs ensure excellent ride stability and notched shoulders evenly distribute stress to ensure extended service life. The continuous ribs simultaneously work with a high density sipe network to enhance wear life and extend usability. A multitude of four wide grooves along the tread swiftly channel water from the contact patch in order to provide powerful traction and wet performance.
