These 175 mm x 50 mm profile tires from Sunmate offer a good balance of rolling behavior, traction, and weight. The 50 mm wide rubber tires can take you anywhere, even on the toughest surfaces. They also provide excellent grip in wet conditions. To keep the weight as low as possible, we use a 5-spoke double-spoke rim made from a blend of aluminum and composite materials, which looks great and sporty. The rim not only looks good but is also very durable, making it easy to replace flat tires. The tire is equipped with a Schrader valve and can be inflated to a maximum of 50 psi / 3.5 bar.
