I finally swapped the stock Dunlops for some Pirelli Diablo Stradas at about 4980 miles. Cords were beginning to show on the rear tire. I neglected to take any photos illustrating the condition of the Dunlops.
A friend and I cut some rubber tubing in half to protect the rim and then set to work with a bead breaker, a valve stem tool, a couple of prybars, some tire lube and a piece of cardboard. If not for all the drinking and screwing around we probably could have finished in an hour or so.
Needless to say, the brand new Pirellis are far more responsive than the worn out Dunlops. Once I get some more miles logged I may update this posting with further impressions.
