This summer I purchased a pair of 25c Michelin Pro 4 endurance tires. I am very disappointed in these tires and miss my 2005 25c Michelin Pro 2 tires that preceded them. Right out of the box, they failed to measure up in width to the Pro 2 tires. These Michelin Pro 4s matched the width of other 25c tires, but I was hoping they would be oversized like the notoriously wide Pro 2s. The first, but not only, disappointment for me.
The tires rode harsher than the Pro 2s. The tires did feel faster rolling but did not feel any better in turns leaned over or not. I did not put many miles in these tires in the last year, sticking mainly to my mountain bike. Well, while just riding along and not hitting anything, the rear totally failed on me. Split right along some of the visible bands of the casting.
I assume I might be able to get a warranty replacement, but why. I did not like the tires and just purchased a set of Bonti armoured 28c tires. I am hopeful they will be much better.
