Took Little Red to a track day at Summit Point on Wednesday. Rainy all day and slick track. My current tires are 175/70/13 Sumitomo HRT 200. They preformed great last year at the track and are fantastic when cnditions are dry BUT, as advertized, they are not a wet tire. Spun out in the fisrt 2 sessions and used better judgement and did not go out in the afternoon. Three cars did end up in the walls. Would invite suggestions on tires for wet conditions. Also what is the major difference between wet/dry tires? The tread pattern or the rubber compound?
