Michellin Pro Race 2 700x23, I chnged the rear tire after 2,200 miles, but still have the same one on the front. To tell you the truth the only reason I put a new rear one was of so many cuts and scrapes from the road or else it would still be clocking more miles.IMO they tend to have some lateral flex after 1,000 miles, for me the main center lining is solid, but the side walls a little thin. They seem to be built for light riders, I am 170 with 23 tires and still feel they could be a little stiffer. They are a pain to install, super tight fit.
