I ride on the roughest, most crap strewn road in America. I tried Continental Gatorskins, Specalized Armadillos, and Schwalbe Marathon Pluses.

The Gatorskins, as another poster noted, were nothing special, had a few flats, etc. They were slightly better than the Continental Contacts that I had before which in turn were better than the crap Kendas that came with the bike.

Then I tried Specialized Armadillos. I had VERY bad luck - several flats, a gash in the front tire - and worst of all, tread delamination after about 1,000 miles,
maybe a bit less.

Switched to Schwalbe Marathon Pluses a year ago or so (about 1,200 miles). Zero flats or problems thus far.

This is the 21st century, as far as I'm concerned, flats are unacceptable. I haven't had a flat tire on a car in almost 30 years, I
expect the same from my bicycle. I was so mad after the Armadillo experience, that I was ready to switch to solid tires - but
gave the Marathons a try. Definitely far better than anything else I've tried to date. Still, I run heavy duty tubes with slime as
a precaution - they saved my bacon on more than one occasion with the lesser tires, and got me home without the need to
resort to a roadside repair.

I haven't tried the Michelins - with that storied name, I'd expect something good.
