The lengthened tread life is guaranteed with the tread design and the durable compound. The tread design's tie-bars stabilize the surface contact while the tires are in motion, ensuring even pressure distribution across the tread area. The tire avoids irregular wear formations across the tread area, preventing irregular wear formations. The stronger compound elements prevent premature wear formations, greatly improving the usability. The tread's funnel-shaped groove pattern avoids stone retention, by ejecting rocks stuck in the footprint before they can drill into the tread area. This combination greatly enhances the usability.
