Riding in new orleans through all the detritus on the streets, I constantly have objects cut through the tread and puncture the tube, usually every 250 miles or so.
When properly inflated they roll pretty well, though not nearly as smoothly as my newer conti gatorskins. The contacts seem to have good traction, especially over the wet metal bridge gratings and trolley tracks I have to ride over. I haven't tried them in snow.
That's very interesting to know. The German website says they were developed with a silica and carbon compound for 'factory environments' ie rolling safely over wet metal or concrete surfaces, rails, oil spills etc , apart from not getting punctures. They also warn it isn't a 'comfortable' touring tire.
1-hr on them is no big deal - provided they don't get flats !!. But now you raise doubts.
As the fine quartz and limestone gravel I ride over for 30% of the journey will grind anything down, add that to the rest of the debris on city roads and only time will tell.
The ambient temperature and UV exposure in The Big Easy is much higher than 55 deg north, so their 'non-touring' compound will be somewhat softer. But I don't know if that would affect the wearing quality much.
Take a look at how the Marathon Plus 700 x 35c is holding up after 3,500 miles on the back and 700 on the front.
I don't know how people get 10,000 miles out of any bike tire. I got 5,500 from a Schwalbe Marathon (over London roads) without a puncture, then suddenly it started (like this Marathon Plus is now) getting tons of nicks, cuts and debris stuck in the compound - and flats.
