Dave Swrote a review of Michelin Pro4 Endurance Tire - Clincher on January 1, 2016
Familiarity: I've put it through the wringer
I had some bad experiences before with Michelin. (It was one set, but for what I had paid it was enough to turn me off to them). I've slowly been coming back around. 2 years ago I discovered the Lithion 2's. I liked that the wore well, and could pick them up for about 1/3 of the price of gatorskins.
I found a deal on Pro4 Endurance earlier this year and figured I'd give them another shot. I'm a big guy riding on average to downright lousy roads in New England and I managed to put 2100+ miles on them before flatting. The flat was from overall wear, more than a failure.
I'm no pro, so I can't speak to the nuances of performance. But to me the felt responsive, they cornered well, and felt like they took some of the edge of the choppy roads. When the Christmas deal came up, it was a no brainer to stock up for this year.
