i have had these dunlop road smarts on for about 5500 - 6000 miles now. the rear tire has some cupping/scalloping going on. whats the deal? i this normal? havent checked the pressure lately, but it was spot on last time i checked. and the dual compound is nice, but it almost makes the tire square off quicker. cause i do hit alot of twisties, and the the center (hard compound) wears alot less its peaked and squared.. ill have to upload some pics tomorrow. i like these tires, they grip very well for a dual compound tire, but im not liking the wear patterns they are forming. i guess ill be trying out the Michelin Pilot Road 2 tires next go round id like to just throw some pilot power 2ct but i know i wont get any mileage at all out of them.
