Mountain bike tires are specially designed for off-road cycling, providing traction and stability on various terrains. They typically feature a knobby tread pattern that helps grip loose surfaces like dirt, mud, and gravel. The width of these tires can vary, with wider options offering better stability and control. Tires are made from durable rubber compounds to withstand rough conditions and punctures. They come in different sizes, measured in inches, and can be tubeless or tube-type. Proper tire pressure is essential for optimal performance, affecting ride quality and handling on trails.
