I bought a closeout Novara Randonee in early 2015 with these tires installed (70032).
The rear tire started showing orange wear-through around 3000 miles. In that time, I'd had one flat on it. I replaced it with the same model.
I replaced that tire after 3700 miles. No flats.
I replaced THAT tire after 6300 miles. It was showing quite a lot of orange at that point, but STILL no flats.
I've got about 4000 miles on the current rear tire. I should start keeping an eye on its wear, I guess - I've got a full fender on the back, so I don't see it when I'm riding.
Oh, and the front tire? It's orange all around now - fair enough, since it's got SEVENTEEN THOUSAND MILES on it. With no flats. (Clearly, my weight is mostly over the back, but still.)
Now, I ride on a rail-to-trail that's paved over some of its length, gravel-screened over some, with few road crossings and not a lot of trash. I expect I'd get more flats if I did a lot of road miles. But I've been beyond impressed with these tires, and I'll certainly keep buying them.
To the mounting problems other users have mentioned these are a LITTLE hard to get on, but nothing out of the ordinary in my experience. It may be that my rims are a little looser than some others, or it might be a temperature thing (I've usually changed them in warm weather).
Thank you for your feedback.
