The middle section of the Byway's tread is built for endless fast-paced adventures on paved roads, while the side section, with its distinctive lugs, provides plenty of support when it comes to muddy or loose footing. Extending them into the sidewalls increases cornering traction and adds additional protection to the pattern. New WTB tyre protection - SG2 In addition to its low weight, the SG2 tyre protection provides excellent protection against punctures and punctures. Such tires have a high value of 120 TPI - or threads per inch, which represents the density of fibers in the carcass of the tire. This new protective layer is lightweight and features an ultra-thin nylon liner that covers the entire surface of the shell from heel to toe. So you can go out on any surface without fear of punctures. How much more durable are the new tyres with SG2? Laboratory tests show that the addition of SG2 provides 33% better sidewall protection and 17% better tread protection than standard 60 TPI tires without SG2. Gravel rides are becoming more frequent and longer. The riders will not be afraid of difficult terrain. That's why WTB has come up with durable tires that will hold up on any surface.
