Product description
The Byway RS is built for pure speed on gravel. A slick centerline paired with low-profile transition and shoulder knobs delivers exceptional rolling efficiency on hard pack gravel, and pavement, while maintaining predictable cornering traction when conditions become loose. Combined with patent-pending aerodynamic technology integrated into the sidewalls, the Byway RS delivers everything riders expect from a high-performance gravel tire while helping conserve valuable energy at higher speeds.

*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 may also consult wtb.com for the most up-to-date tire pressure recommendations from WTB. We calculate pressure recommendations based on an average rider weight of 160-180 lbs and suggest increasing our minimum recommended pressure on WTB.com by 2-3psi for every additional 10 lbs of rider weight. Never exceed the maximum tire pressure marked on a tire.
Frequently Asked Questions
One of the highlights of new construction is that opens up great weight saving opportunities while still retaining excellent durability.
The short answer is yes, although the real savings come from the front of the bike where you're really pushing into the wind.
The patent pending vortex generators and trip strips works in stages to draw the airflow close to the wheel system, minimising the low pressure and maximising every pedal stroke.
Changing the tire profile for aerodyanic gain would compromise the primary goal of creating tires that deliever the charateristics riders demand from a tire. Great puncture resistnce, low rolling resistance, and maximum grip are always priority. Once that is achieved, we then looked at how to make them more aerodynamic.
Yes you can fit these tires to a mountain bike and realise some benefit, although the aero gains are larger at the higher speeds usually achived by a gravel bike.
You can find them at WTB.com, WTB.eu, or ask for them at your local independent bicycle retailer.
SG2 Puncture Protection
Three-piece SG2 puncture protection technology is used in WTB’s wide gravel and SG2 mountain tires. The nylon protection layer comprises three separate pieces to provide full bead-to-bead coverage while maintaining the stretch and conformity characteristics desirable in wider tires. The nylon fibers within SG2 feature a uniquely flat profile, which reduces the amount of rubber needed to fill the gaps between fibers. Improving the fiber-to-rubber ratio increases puncture resistance, reduces weight and improves the overall liveliness of a tire.
Dual DNA
Dual DNA rubber compound combines harder, faster-rolling center sections with softer, grippier shoulders for optimal performance and weight. Additionally, each tire is equipped with robust SG2 puncture protection to ensure durability and reliability on any terrain.
Stromm Aerotech
We partnered with the aero experts at Stromm to counteract aerodynamic drag using Vortex Generators and Trip Strips placed at key intervals along the tyre.
This revolutionary patent pending technology works in stages to draw the airflow close to the wheel system, minimising the low pressure and maximising every pedal stroke.
Zero Plastic Packaging
All new WTB tires are packaged using 100% recycled materials and zero plastic. Our engineers and marketing team are constantly working towards reducing the amount of packaging our products requiring, while still providing you with the necessary information to make an informed purchasing decision. It's no small task, but minimizing the total amount of packaging has become an integral part of product development.
This results in simplistic packaging using more recycled materials and less zip ties. In the next few years, we're working to ensure 100% of WTB packaging goes in the recycling bins.
Tried and Tested
"I ran the Byway RS 50 in the rear at Unbound 2026 and spent most of the race wishing I'd also put it up front. For flat or rolling courses where conditions get muddy, it's unmatched — the tread sheds mud instead of packing it, so you're not carrying extra weight or stopping when the course gets sloppy. It's also just wicked fast on dry hardpack. If you don't need aggressive tread security, this is your tire." - Whitney Allison, professional gravel racer
