WTB Byway Gravel Bike Tyre with Smooth Rolling Performance

WTB Byway is for days of endless hard pack exploration and gravel grinding, while also providing noticeable efficiency on any pavement linking it all together. A swiftly smooth centre line is paired to a textured intermediate section that provides a seamless transition onto small outer knobs for unwavering traction in loose dirt and gravel.

Prominent outer knobs also extend down the sidewall to provide an additional level of defence from roadside unpleasantries of all shapes and sizes.

SG2 Puncture Protection System

These WTB Byway tires are available with WTB's SG2 Puncture Protection System, which is a lightweight nylon insert that provides bead-to-bead coverage and ensures every area of the tire is defended against slashes and punctures. As events become progressively rougher and cyclists pedal farther, gravel gets tougher. It only makes sense for gravel tires to become tougher as well.

  • Dual DNA Compound:
    Two rubber compounds. The centre line tread features a firmer rubber compound that rolls fast and resists tread wear, while the side knobs are composed of softer, slower-rebounding rubber to improve control and grip. All Dual DNA tires fall within the Fast Rolling category.
  • SG2 Puncture Protection:
    Nylon fibres have a flat profile, which reduces the amount of rubber needed to fill the gaps between fibres and minimizes weight. SG2 was specifically designed to be a puncture protection layer, but it also improves air retention and eliminates seeping at the sidewall.
  • Tyre Pressure Information:
    WTB's tire pressure recommendations have changed over time due to further developments in technology. Riders may always reference the markings on their tires for allowed pressures ranges, but WTB calculate pressure recommendations based on an average rider weight of 160-180 lbs and suggest increasing the minimum recommended pressure by 2-3psi for every additional 10 lbs of rider weight. Never exceed the maximum tire pressure marked on a tire.
