25mm on wider rims hold up under poor conditions, clean design, mounting is tight but that is wheel-specific, not as bad as others. Retail price is in-line with other "armored" tires, but look for sales.

Like many tires, test carefully when new, otherwise nothing so far after "break-in."

My benchmark for flat-free road riding is the Schwalbe Durano series in 25mm, never having had a puncture flat in over 6,000 miles. However, both the weight and ride of the Duranos is “heavy.” Rolling resistance is high. That said, I will always ride a pair because of the confidence I have in them. But when Michelin announced the “revised” Endurance Pro4 model, I thought a test was in order, having years ago commuted happily (on ideal conditions) on Michelin Lith-ions. When conditions became less than ideal, I had to test other tires, and went through several before settling on Duranos since about 2013.

Initially I mounted the Pro4s on my 24-28 spoke RoL Alpe D'uez wide rims to “weight-balance” with heavier Duranos on slightly lighter 20-22 spoke wide-rim Neuvation wheels, but I later switched them. Until winter, I swap wheels out on a monthly basis since my rides are fairly routine, from 24 to 52 miles, more “Belgian” than mountainous. Most of my rides are three quarters in country and one quarter distance in city conditions, including a paved trail with predictable puddles under a bridge. Variable road surfaces and plenty of construction and auto debris and glass.

I weigh 160lb and ride pressures between 75-85 psi. But I will usually test tires at nearer max pressure for a couple of (slightly more jolting) rides.

I managed about 600 miles on these before winter conditions set in, when I generally ride my sturdier set of wheels with the Duranos, but I can report a smooth and trouble-free experience. My ride-out requires a choice of hills from the get-go, and the Pro4s were are sprightlier on the steeper climb. Cornering is very good, the rubber formulation seems to have the right balance for grip but with a smooth roll-out. But I did come a cropper when they were bran-new, trying to turn from a stand while on grass-clippings, they came out from under me. Nothing like that has happened since. I will admit that I have not ridden in any deep rain or up any mountains.

The tires are physically similar to Ritchey Race Slick, with no sipes. The appearance is clutter-free and they clean up beautifully. I have seen no sidewall problems that plagued every Continental tire that I ever rode. It remains to be seen if these tires will match the sterling endurance level of the Schwalbe Duranos, but for performance in the conditions most road riders face, they are a definite thumb's up so far. I give the highest rating with the caveat that I have not put 1000 miles on mine.

Grip in wet and dry, resistant to cuts, long lasting, seem to roll fast, decent to mount

I can't think of any weakness off handed. At least I've not encountered any so far.

I've got the 25mm version. Mounted on a Velocity A23 rim gives me a tire that measures over 27mm wide. Ride quality is very nice. Handling is equally nice, with no surprises when turning into corners. The tires grip well in the wet and in the dry (much better than the Krylions, the most comparable tire of the recent Michelin past). The tread seems to be holding up well with no cuts. I've had no flats, but I can't say whether that's the result of clean roads, good puncture protection, or luck. On the road these feel no different than the Pro Race 3s I had before and feel equivalent to Continental's GP4000S tires. The tires are holding up better than Schwalbe DD Ultremos.

Ride, longevity, grip, value

Not easy to mount, I still get flats

I've tried many tires and many brands, and I keep coming back to Michelin. I've had other tires that do 1 thing really well, and are not good at the rest. These Pro4 Endurance do everything well. They're quick, ride nicely, corner well, and seem to be pretty tough. Although these to have a puncture resistant layer in them, it appears that it's not on the sidewalls since I have had a flat or two due to cuts in the sidewall. I've had the Pro3's before, and the 4 is better in every way. I'm very impressed w/these, and would certainly recommend them to anyone.
1 word of warning, though. Corner slowly for the first 50 miles or so. They do have a slick release compound on them when new, and could cause you to crash if you corner too hard too early in their life. I forgot about this fact, and learned the hard way not to corner hard on these when they're new. That being said, I still think they're great tires.

good handling, high mileage, excellent flat protection, smooth feel

the 23mm can be hard to get on rim if you don't stretch tire before installing, this is a training tire not race

let me first address the clown in the above review...he opens his review with a plug for his website, which i made the mistake clicking. It is all advertisements with no real content. I question his motives for even writing a review other than to plug his site. "guru my ass" .....anyway i ride 10-12,000miles a year. I've been racing for a couple decades. I use these as my training tires. On average I get 2500miles on a rear tire. I ride rough roads in the middle of no where with lots of debris. These tires aren't perfect, there is no perfect tire, but they do a fantastic job of high mileage with excellent flat protection while still having most the characteristics of a high performance race tire. I used the older krylion version and got more miles out of them but less performance. I like the pro4 endurance better because of the improved handling over the krylion. If i really wanted i could get 3000 or more miles on tires but i'd rather swap to a new one than run the risks old tires present to get that extra 500 miles....i have had a few flats but no tire on the planet would done protected me from some of the debris which caused them (like wire from a radial tire...good luck stopping that) i have also gone over 6000miles on a couple sets with no flats and have ridden though lots of glass without a problem...i have ridden every tire made and for training these best suit my needs (reliable, high mileage, good performance) as for racing tires, that's another story and doesn't apply to this review

Good Rolling Tire, Sheds Death Pebbles in DRY conditions-- WET-NOT SO MUCH

Seem to attract Pebbles in wet and holds and seems to cut easy

See my review ongoing review http://www.thebikinguru.com/

Michelin's new Pro4 had peaked my interest from the early reviews, albeit from Michelin itself. Michelin’s own page has the moniker “A Better Way Forward-Longer Tire Life and Enhanced Protection”. My response is; well maybe not on VT rain soaked roads with variable road debris. ( aka death pebbles )

Michelin has revamped their line of tires a bit. Their previous famed Michelin Krylion Carbon 3 was pretty good, had a pair and flatted one of the tires after only 200miles in dry weather. They had the same bead to bead protection and supple casing that the new tire line from Michelin is boasting. Fast forward, Michelin brings out the new set of tires. In the order of puncture protection, they are the Pro4 Endurance, Pro4 Service Course,Pro4 Comp Service Course and Pro4 Limited Service Course, all in clinchers and foldable. The Pro4 Service course offers a nylon breaker for puncture protection, the Pro4 comp service course and the Pro4 limited service course do continue along the lines of the Pro4 service course but it is unclear from Michelin's own website what type of puncture protection is being offered. Michelin does say " Its dual-compound technology employs new silica-based compounds and elastomers ". So, how do the the Michelin Pro4 Endurance measure up to the Gartorskin? Read on!
