They eliminate mud and snow stuck between the tread elements, preventing them from blocking the tire's terrain surface contact. This self-cleaning capability also eject rocks from the grooves, actively resisting stone retention from harming the tire's casing. Furthermore, the nylon belt reinforcement of the internal structure strengthens the casing against the off-road driving conditions. In this manner, the structure avoids off-road damage, such as punctures and cuts, from harming the sidewall and tread area, lengthening the tire's service life.
