Falken 615s are very grippy tires... I just don't think it fits the bill of the OP.
He has a DD, which means he will need decent wear. Thats not the 615. Great grip and go Fast it sure will though.
I would have to ask the OP whats more important... wear and DD characteristics, or the go fast part.
My first reaction would be Goodyear Eagle F1s. If you like OEM, but want it to last longer in a greater range... then that would be my choice.
If you say you need greater wear characteristics, and get into the Budget tires, the Hankooks would not be on my list. Instead, I would say BF Goodrich g-Force Sport (slighty better overall minus wet traction is average) or Kumho ECSTA SPT (which will be discontinuing the 215/40/17, so if you do have a road hazard, might not be able to match it again...)
The Cheap solution will run you about $500, while the Goodyear solution runs you $820. $500 scenario has last me about 15,000 miles on the rear, while the Goodyears last me 10,000 mils on the rear. The Falken 615s didn't even get me 6,000
Overall, I am currently using Toyo Proxes 4 (I know All-Season tires... :eek ) during the winter since I drive it through the year, and I use Toyo T1Rs during the summer because Goodyears don't have my size. Otherwise, Goodyears would be my choice!
