Sunlite UtiliT Alphabite H518

This tire is designed for 20-inch wheels, which is a standard size for many youth mountain bikes. Before purchasing, check the sidewall of your current tire to confirm it lists '20 x 2.125' or a similar 20-inch diameter to ensure compatibility.

While the Alphabite H518 is designed for dirt trails and off-road use, it can handle occasional pavement. However, the large, widely spaced knobs will create more rolling resistance and noise on smooth surfaces compared to a dedicated street tire.

Yes, this is a tube-type tire. You will need to install it with a compatible 20-inch inner tube to hold air pressure.

The maximum recommended pressure for this tire is 65 PSI. We suggest staying within the manufacturer's recommended range printed on the tire sidewall to balance traction and durability.

Wire bead tires are generally stiffer than folding tires, which can make them slightly more challenging to mount onto the rim. Using a set of plastic tire levers will make the installation process much easier and help prevent damage to the rim.
