I've put almost 1K miles on them, including LOTOJA this year. I've been a Cont 5000 GP user, and decided to give these a try. These are easier to mount than the Continentals, but rolling resistance feels a little more tough. There is also no wear indicators so I'll just have to guess when it's time to change.
I was using the lighter Michelin Power Competition for a few years but they were fragile tires. After I got a few sidewall punctures I switch back to Pro4 Service Course-a little heavier tire but much more durable. Even at 219g the Pro4 are still lighter than many of the other tires in the same class. My old Pro4 25mm would inflate to almost 28mm wide. These newer ones are more like 27mm after inflating to 85 psi. I get over 4000 miles for the rear tire and 5500 for the front. The grip and roll resistance are excellent even without the gimmicky tread patterns and fancy compounds.
Have always liked these tires for the type of tires they are. Low resistance and light. They are just a bit more susceptible to flats. Contiï¿½s get less flats but are a stiffer ride.
I have been riding the Michelin Pro 4's for years. In my mind they are the best value for the dollar out there. They hold up well and handle great. I have another set of wheels with the Pro 4 Endurance I use on longer rides. Rode across the country on a set several years ago and they did not let me down.
Rear tire lasted 2600 miles and through the winter & spring grit season. I never got a flat, I just noticed a spot where the rubber was gone and the thread was showing. It could have been from a skid but I don't remember ever locking up the wheel I've really never been able to notice any difference on grip or ride quality of any of the tires I've used over the last 30 years of 5,000 miles of riding I do a year. Can't even say I noticed anything when I went to 25mm from 22mm. Miles per tire are about the only way I can judge really a tire. I've used them all Armadillo, Gaterback, hard shell, just about all of them. These tires lasted as long as any tire I've ever used. This is my second pair, I'm very pleased with them.
These have been my goto road tire since the Krylion Carbon vanished - good profile & great value... enough rubber that by the time it's gone the side walls are starting to go. When I get the alert that they are on discount I always buy two for backup.
Nothing I don't like. Absorbs bumps well, smooth, fast, have only ridden in dry conditions, but seem to have good traction. The 700x25c measures 700x27c on Bontrager SSR rims, but enough clearance on the frame's brake arch that it is OK. Like that they are a little wider, running lower pressure than the old 25's I had on there (weren't Michelin). Very pleased with them. Haven't found any drawbacks.
Rode these tires on asphalt road with less than 600 miles and both have 0.25-0.5 inch splits. Outer rubber coating is falling apart. They are comfortable with good rolling properties but will not last long.
These are really fun tires that grip fantastically on corners and best part start to sing around 18mph on a smooth road. I find the 700x25 size I use easier to mount than it's Conti rival, yet just as durable.
