It enhances the tire's durability by maintaining its optimal shape. As the tire does not deform under the pressure affecting it, it is capable of performing to its best capability. The internal structure works together with the tread design's inner area, which boosts the snow traction, to ensure a comfortable drive. The optimized tire shape allows the tire to closely follow the road surface, while the tread keeps the excellent traction. This combination reduces the road vibrations heard in the vehicle's cabin during the drive, which ensures a comfortable drive.
