ethirteen Optimus Trail MTB Tires
The Optimus 2.4" is designed to deliver confidence inspiring trail traction with lower roll 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, but a tread and casing configuration that targets maximum rolling efficiency .
The Optimus features ethirteen's Endurance compound, with a firm base layer and center knobs and softer medium tack sidewall knobs for minimized rolling resistance, 30% higher durability and wear-life, and biting traction in the corners and off-cambers. The Optimus Trail casing is single ply 72tpi casing with tubeless insert, but takes advantage of a nylon breaker under the tread for heightened puncture protection and a more supportive feel in rougher terrain.
The Optimus tread pattern was engineered with shorter, tightly spaced center knobs, which create a more efficient rolling contact patch through the center tread. This also enhances acceleration and climbing properties. Center knob sipes alternate between parallel and perpendicular to enhance both braking and cornering traction. More widely spaced transitional knobs help to control traction consistency and predictability when transferring through lean angles while self-cleaning effectively. Sidewall knobs are designed with a sophisticated profile to dig into looser terrain during aggressive cornering, and hook up on off-cambers. Horizontal upper sipes and arched cutaways with accordion side sipes help to improve flexibility in uneven terrain, while controlling sidewall knob deformation and roll-over at high lean angles.
