L. Carbon tread compound. The Long Link Carbon creates a long chain on the molecular level throughout the tread area, and this spreads the driving pressure equally across it. The even distribution of the forces of acceleration, cornering and braking prevent irregular wear on the tire, forcing it to wear out evenly. The longer lasting, even tread wear of the tire and the stronger, slower wearing tread extend the life of the model. The L. L. Carbon also improves the rolling resistance of the tire, as it reduces the tire's weight.
