I am new to SCCA ITA racing and have completed only 2 races last yaer. This year we are looking forward to an entire year of schools and racing. One item that I do not have and am unclear on what to get is a good rain tire. I have a couple of opinions but only 1 from a real racer. I will be using a 205/50/15 size. What do you guys think is a good rain tire in my class?
