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.
