Rain tyre

[1] Rain tyres are not used in NASCAR, ARCA and INDYCAR sanctioned races held on oval tracks as these races are invariably halted when the track is wet due to safety concerns regarding the large amounts of spray involved reducing visibility, as well as a lack of traction in banked corners at high speeds.

If this water is not displaced, the car will experience an effect known as hydroplaning as the rubber will not be in contact with the ground.

When rain has stopped falling, and a track is in the process of drying, it is not unusual to see drivers intentionally driving through wet puddles and damp portions of the course, in order to cool the rubber and stave off tyre deterioration.

This means that the wheel spins faster and more water is thrown off the tyre by overcoming centripetal force.

[citation needed] Some racing series such as Formula One allow an intermediate (inter) tyre.

[3][4] They were the first to understand the water-deflecting properties of directional V-shaped tread and the first to use biomimicry with the development of “Shark Skin Technology[5]”, which helps to prevent aquaplaning.
