Optimus Tires deliver confidence-inspiring trail traction with minimal rolling resistance at XC/Down Country weights. The 2.4'' high volume design promises the comfort of burlier trail tires and the same ability to run lower air pressures, with a tread design and casing configurations that target maximum efficiency. e*thirteen's Endurance compound means high durability and wear-life. When combined with the tightly spaced center knob and alternating traditional knob tread pattern, the result is enhanced efficiency, acceleration, and climbing prowess. Pronounced sidewall knobs dig into looser terrain during aggressive cornering, and hook up on off-cambers during high-speed descents.
