This, along with the durable compound, lengthens the tire's tread life. The solid shoulders' constant road contact enables the tire's footprint to evenly spread out the driving pressure on the tire's footprint. The equally distributed forces of acceleration, cornering and braking effectively prevents the formation of irregular tread wear across the tread area. The special durable tire compound is wear-resistant which slows the tread wear rate down significantly. The slower even tread wear guarantees an extended tread life and usability.
