I can't help much on the size, but I will say this! I have ran both the Hankook's and the Yoko's (which is what is currently on my car). IMHO the kooks are a FAR better tire in regards to performance, quietness and look a hell of allot better! With the kooks I felt allot more confident when hitting the twisties hard over the Yoko's. The Kooks I could not even make them squeal regardless of how hard I cornered, the Yoko's take little to no effort to squeal around the corners. My ONLY complaint with the Kooks is they seemed allot harder to balance! As far as pricing, go to discount tires direct, ask for Wyatt and he will fix you up! You CANNOT beat their prices as they offer free shipping and in most cases they will be on your doorstep in 2 days. Also they offer a no BS replacement warranty that replaces blowouts, etc. unlike tire rack and the others, with discount you do not have to send the old tire back and argue about tread depth and all that crap. Simply call them, they run your credit card for $20.00 for the replacement warranty on your new tire and it's on your doorstep in 2 days. I am no way affiliated with Discount tire but I will not buy tires anywhere else! Good luck!
I am in agreement with you regarding discounttire. My last 6 sets of tires have been from them and have been pleased.
I believe the Hankooks are discontinued for 22's. Please correct me if I am wrong
