Sunlite K831 Alpha Bite MTB Tire

This tire is designed for 26-inch wheels with an ISO diameter of 559 mm. Please verify the sidewall of your current tires to ensure they match these dimensions before purchasing.

The large, widely spaced knobs are engineered to bite into loose surfaces like mud and sand while maintaining enough contact for stability on hardpack trails. It is a versatile, all-around tread design for general mountain biking.

This model features a wire bead. While this makes the tire slightly heavier and less compact than folding-bead alternatives, it provides a very secure fit on the rim and is highly durable for standard trail riding.

While you can ride this on pavement, the knobby tread pattern will create noticeable drag and vibration compared to a slick or semi-slick tire. It is best suited for off-road use or mixed-terrain commutes where traction is the priority.

Yes, this is a clincher tire and requires a compatible inner tube sized for 26-inch wheels. Ensure your tube's width range accommodates the 1.75-inch width of this tire.
