There’s been a lot of talk about wider gravel tires recently. Sure, the larger contact patches may yield better grip, but what about aerodynamic drag and increased weight? <\/p>\n

Well, thanks to a partnership with Stromm, WTB has introduced three new high-volume gravel tires that are pretty light and<\/em> up substantially faster in the wind tunnel. <\/p>\n

The new collection is engineered for wide gravel rim compatibility (25\u201332mm internal width), with tread and sidewall profiles optimized around a 28mm internal width. Construction centers on a 120 TPI casing with bead-to-bead SG2 puncture protection and a Dual DNA rubber compound featuring a harder center compound for decreased rolling resistance and a softer shoulder compound for increased grip. <\/p>\n

The chevron-shaped parts are the vortex generators, while the line directly beneath them is the trip strip. <\/figcaption><\/figure>\n

The defining technical feature across all three models is a patent-pending aerodynamic treatment incorporated into the sidewalls: trip strips and vortex generators designed to manipulate airflow over the tire and wheel system, which controls boundary layer separation and reduces the low-pressure wake that would usually increase drag which slows you down. <\/p>\n

Stromm validated the design at the Jerry Baker Memorial Velodrome in Redmond, WA. Measured drag reductions compared to an identical control tire without aerodynamic features were 5.8 watts at 30 km\/h, 9.3 watts at 35 km\/h, and 13.8 watts at 40 km\/h. Notably, tires were tested both clean and dirty to make sure these aero benefits would actually carry over once the tire touches dirt in the real world. Want to read more?

Tire Models<\/h2>\n

The three models are differentiated by tread profile and intended terrain as well as size. Currently, each model is only offered in one size, and the tires get more aggressive in tread as they get larger. Note that each tire is 10g heavier for the claimed weight on the black sidewall version.<\/p>\n

The Byway RS 50 features a slick centerline with low-profile shoulder knobs suited to hardpack and paved surfaces. At 620g claimed, this one actually came in at 613g.<\/p>\n
