The R-compound was racing-inspired and it was designed to use in racing tires to ensure their best high speed performance. This compound prevents heat build-up and keeps the tire's traction during its performance. The extra sticky compound guarantees the tire's traction at all times. The tread design, on the other hand, features a semi-slick pattern that maximizes the tire's road surface area. The better road contact ensures the tire's grip on the road surface throughout the drive.
