I know this has probably been posted somwhere in the last 25000 posts but instead of reading all the search hits for tires I figured I would ask again. I am running Dunlop 736 (9?) and after just a few rides (like 4 -30 milers) the knobs are well worn and rounded. I know this has alot to do with how much the tire is sliding and spinning. I thought I would ask other 650r owners what they are running. Is the trade to a harder tire worth the traction trade-off?
