Someone informed me this weekend about getting the used tires from our Formula SAE team. One of the alums who used to do it told me to check it out, and offered to buy them from me if I got them, he said they run 13x8 Hoosiers. I didn't think about using them because I didn't know if I could stretch them over some OEM rims or something. I went up today to check it out, and for the last two years, they've been using 13x7s, which actually look smaller than my Azenis. Could I fit these on any OEM wheels, something I could get cheap? Also, will 13s clear my Si brakes?
