Has any one ordered used race rubber from him? If so what was the quality of the product? How was shipping and the entire buying experience? I can get 225/45r15 Hoosier A6 with 75% left for 140 thats a good deal and a seasons worth of local autocross, if it works out Ill probably buy two sets because of track days and two prosolo's.
So I assume he is selling used tires? If so I would be concerned about the number of heat cycles that they went through.
