If you're still looking for tires i'd look at the Kumho Ecstas 4X - I had some Continental DW's on my car. They were pretty good but wore super quick.
The Kumho's are way quieter and have the same traction rating but come with a 40k mile warranty and have 420 treadwear.
I honestly get better performance out of the Kumho's than I did the Continentals and the Conti's were 50bucks more per tire.
