Is anyone using these tires and what do you think of them for street use? They have the factory 215/40-17 and 255/40-17 sizes I want and I thought they might be a good new alternative in the increasing limited selection we have for tires. I don't want the Dunlop's and I can't seem to click the 'place order' button on the Yokohama ADVAN Neova AD08 or Continental ContiSportContact 3 choices. My Goodyear GS D3's are gone on the rear.
