I am shopping for rain tires and wanted to get input on which ones to buy. I race an IT7 primarily at at Sebring, Daytona and Moroso. My choices are Toyo Proxes at $120 each, Hoosier Dirt Trackers at $93 each and BF Goodrich's at $25 each. The Goodrichs' have never been used but are 1-2 years old. They are left overs from when Spec Racer Fords changed their spec tire. Also, how long will the rains be good for if they get little use or no use. I have heard one to two years. I am a mid pack racer and will race 9 weekends this year.
