I have run Goodyears before but just recently purchased the Vredestein Ultrac Sessanta. What an awesome tire. Below is a few forums that review them if you are interested.

I run 245/45/17 in front and 315/35/17 on the rear. I just purchased them about a month ago and love them. They stick to the road and give a great ride. Not sur eif htey are available near you but I purchased mine thru Performancetire in california. They were great to order from. For the price it is worth a look.
