Byway 650b TCS Tire - Tubeless

What Our Gearhead® Experts Are Saying:

"I’ve run the Byway for over a year and it’s a standout on pavement-to-gravel transitions. The smooth centerline keeps things quick on the road, and the SG2 layer makes it way more resilient than a lot of other supple gravel tires. It’s fast, tough, and super dependable for long days in the saddle."

WTB’s Byway 650 x 47 TCS tire with SG2 puncture protection is purpose-built for mixed-surface riders chasing comfort, efficiency, and reliability. It begins with a slick center tread that minimizes rolling resistance, ideal for pavement transitions and fast segments. Transitioning outward, angular grooves and supportive diamond tread provide bite and stability on hardpack, while reinforced side knobs anchor control during off-camber cornering and sudden line changes.

Beneath the tread, SG2 technology delivers bead-to-bead puncture protection via a tightly woven nylon insert. This not only fortifies the tire against slashes and punctures but also enhances air retention and helps maintain pressure longer between rides. The tire casing is tubeless-ready for lower pressures and reduced rolling resistance, and the Dual DNA rubber compound keeps the balance between fast-rolling longevity and grip where it counts.

With an adventure-first design, the Byway is ideal for gravel riders who regularly transition between road, hardpack, and dirt, and demand a tire that can do it all without flinching. Lightweight, tough, and responsive, it’s the all-road solution for long-distance gravel riders.
