Pilot race is road legal race tyre Slick is just that-slick but differing compounds Inters are intermediate race tyre-good in damp conditions and generally but won't grip quite as well as full slick Wets are wets, race use only on really wet surfaces, don't last very long but give great grip and clear water very well, but on a dry or drying track-5 laps and they're toast.
