Hankook V12s are a very cost effective tire that still provides good performance in terms of grip and noise level. I used Federal 595s as a dedicated autocross tire. They are dirt cheap, so I didn't mind shredding them. Unfortunately they are incredibly noisy. I would never run them for a daily driving set up.
Every now and then, the Hankook $80 rebate and Discount Tire $100 off 4 tires align, and you can get $180 off a set of tires.
