The AS-1 is a high performance tyre which is extremely well suited to spirited road driving. The AS-1 has excellent wet grip and drainage due to 2 straight broad grooves on the outside of the tyre and 1 middle groove which accumulates the water and then diverts excess water to the edge via smaller sipes. By using a ridgid pattern on the shoulder of the tyre cornering force is increased and improves steering as well as reducing uneven tread wear. Ride comfort is also increased by the use of very thin sipes on the tread of the tyre. 10.07.2024, 08:47:24.
