GP's or ZR's?? Being honest, I don't get alot of aggressive riding and will probably never do a track day on these tires. I get some twisties on the weekends but most of the commuting is freeway or fairly straight roads. I know either one is going to handle beyond my capabilities but still, I want a good tire, and guess some descent mileage. I had also heard that Dunlops tend to run a little wider than other brands which kinda helps out in the looks department, IMO. I guess Michelin Pilot Powers would be a second choice as well. Also heard on another site that Michelin is coming out with a 190 designed to work on the 5.5" wheel.
