The stabilized tread elements of the symmetric footprint and the durable compound work together to enhance the tread life. The symmetric ribbed tread design ensures even pressure distribution across the tread area, which avoids irregular wear formations across the tread area. The stronger compound elements slow the treadwear rate down with stronger wear-resistant rubber materials. On the other hand, the knobbed groove bottoms eject rocks from the footprint, preventing them from drilling into the tread area and harming the casing. As a result, stone retention cannot shorten the tire's overall service life.
