The WTB Byway RS Tire brings real aero engineering to gravel racing. A partnership with aero specialists Stromm built Vortex Generators and Trip Strips directly into the sidewalls, cutting drag as speeds climb without reshaping the tire's profile. A Dual DNA compound pairs a fast-rolling center with grippier shoulders, and SG2 puncture protection keeps the casing durable when the terrain turns rough. What Our Gearhead(R) Experts Are Saying:"I stayed locked into a fast line on hardpack all morning, and when the course turned loose and sandy in the afternoon, the shoulder knobs still bit in without any drama. The speed doesn't disappear the second the terrain gets messy."
