Mud-terrain tires are specially designed tires that provide enhanced traction on off-road surfaces, particularly in muddy or uneven terrains. They feature deep treads and large, aggressive patterns that help grip the ground, allowing vehicles to navigate through challenging conditions without getting stuck. These tires are commonly used on 4x4 vehicles and off-road trucks, making them ideal for outdoor enthusiasts and those who frequently drive in rugged environments. While they excel in mud and loose soil, they may produce more road noise and have a shorter lifespan on paved surfaces compared to regular tires.
