Competition tires sizes?
 

Ok, just wondering what size tires i should go with. I know stock is 245/35/17 (i think). I currently run 275/40/17 BFG dra gradials and hook really well. I know autocrossing is totally different than drag racing. I'm looking at differnt tires (Yokohama A048's, Hankook Ventus RSS Z211's, Hankook Ventus Z214's, Kumho ECSTA v710's) and am wondering should i stay with 275's or go down a little bit? I'll be doing 50/50 open track and course setup.
