The tire's grooves feature stone ejecting knobs that eliminate rocks stuck between the tread elements. This avoids stone retention from drilling into the casing and damaging the tire. The special curb bar sidewall depth indicators not only visually portray when the tires need to be rotated, to achieve the maximum tread life, but they also manage to protect the sidewalls from scuffing and impact damage. The strengthened internal structure keeps the tire's optimal shape under the driving and load pressure affecting the model, which enables a secure driving experience.
