SO, i just had my new tires put on Sumitomo HTR Z 3's and they just are phenomenal. The grip is threw the roof and not noisy at all. They were totally worth the 500 bucks for them. http://www.tirerack.com/tires/tires.jsp?tireMake=Sumitomo&tireModel=HTR+Z+III

I did these as my summer tires 2 years ago and they have been fantastic. This will probably be the last season for them but I fully expect to replace them with the same.
