The Kumho Crugen Premium KL33 are manufactured using an all-season compound which reduces the rolling resistance, increases traction and extends the overall serviceable life. The noise emission is significantly reduced by integrating symmetric variable pitches on the tread pattern. The grip remains constant on both wet road and under light snow due to the wide circumferential grooves which separate the tread blocks from each other.This tire pattern and size is ideal for infiniti QX60 and so on.
