I have eight 235-40/17 BF Goodrich DOT slicks from last season all with 5 cycles or less available at $100/ per plus shipping. Normally $252.00 at Tire Rack new. I have run this tire size on eight inch wheels for the last 3 years. These race slicks have wear durability equal to, or better than, the Hoosier R series with stick comparable to the A series. Unlike Hoosiers, which typically give @ 10 cycles max before losing grip, we have found the BFG's to provide over 25 cycles without a precipitous drop in grip and performance.
