Been commuting with the 700x28c(622-28) Marathon plus tyre 4 months/2000km flatless on my city-bike. Every other trip I spot glass and the likes somewhere on my route, but I dont mind very much if I cant avoid running over it. Actually I've been running over large pieces of glass quite a few times while feeling it shatter under me even more, and without a worry in my mind.
As for wear, the front tyre actually still has the thin rubber grate visible all round the tyre on the main contact thread; the one you only see on all-new tyres. On the back tyre, this grate is all gone but no visible thread wear so far.
I expect 5000+ km from these tyres before replacement. And that is the back tyre. Then when times comes, it is just a matter of replacing the rear wheel tyre with the old (but not so worn) front wheel tyre and then mounting all-new tyre to the front wheel. -You want to keep the front wheel safer than the rear.
Some people wear these tyres until the blue smartguard lining becomes visible, but I dont consider it very safe to ride on the anti puncture compound, and the tyre strength/integrity is lost.
5 Stars. Does what it's supposed to.
[Edit] I was wrong about the thread wear. I was just out now checking the wear indicators on the back tyre. They are about half-way worn, leading me to think that there's 2000 kilometers back.
