I have a pair of Marathon 700x35s (not the plus). They can be wrestled on the rim by hand with a little bit of cleverness, and come off reasonably with tire irons. I ran them 1500miles on a tour with no flats and there is barely any wear showing. Here's the bad news though: These two tires went on identical Sun CR18 rims. One of the tires seats perfectly, but one never seats properly. It's high in some places and low in others. Several people have tried mounting this tire on multiple occasions, always with the same result. I found it scary at first, but it eventually lured me into a sense of complacency. On a smooth road where you'd like to really enjoy the ride, you can feel the tire's 'whumpy' spot. Nevertheless, due to the extraordinary wear characteristics, I plan to buy more of these. I'm going to mount them before I leave the shop, though.
