The ENDURO 2 tread pattern is an all-around good tire for just about any surface condition. While the tread pattern hasn't changed from the best selling ENDURO tire, the carcass is now wider to add a bit more stability and traction to the tire. The ENDURO 2 features a larger cross cut lugs which offers long tread life, yet allows the lugs to fold over and bite into the harshest conditions. All AKA SC tires feature the industry standard 2.2"/3" bead sizes.
