As you might have noticed, ​e*thirteen has been pushing hard into new segments of the market over the past few years. Having first produced what was often considered the most reliable chainguide out there, e*thirteen's line has expanded to wheelsets, cassettes, pedals and now tires. We first spotted the new TRS tires during their early prototyping phase last October. After some tweaks, most notably off-setting the center tread and the side knobs, e*thirteen has pulled the trigger and officially launched both the TRS PLUS and TRS Race tires. We've been on a couple sets of both models of the new rubber, so stay tuned for an in-depth review on the TRS tires, launching next week.

e*thirteen TRS Durometers

  • PLUS DUROMETER - 50A / 61A Center

<b>Side knobs</b> use a grippier material for cornering and have a structural, angled base for stiffening the casing overall. <b>Accordion sipes</b> provide a controlled deformation of the side knobs at extreme lean angles.

<b>Reinforced pinch flat zone</b> with thicker, firm rubber where you need it.

<b>Perpendicular sipes</b> for generous braking traction. <b>Reinforced center</b> casing ribs protect against rock strikes. <b>Firmer center tread</b> rolls fast. <b>Ramped center knobs</b> for low rolling resistance.

<b>Parallel sipes</b> on center knobs add tire stability while transitioning from straight line to cornering. <b>Angled sipes</b> on side knobs soften the corner of the knob and bolster traction through turns.

<b>Reinforced sidewall</b> creates a more stable contact patch, prevents folding under compression. <b>Hooked & hookless</b> rim compatible. <b>Tubeless ready</b> casing.
