Out of the box they ride nicer than GP4000Ss, since that seems to be the main comparison point. But they're no better in that regard than Bontrager R3s or R4s let alone Vittoria Corsas. My set of Pro4s lasted 3500 miles before I lost confidence and relegated them to the indoor trainer, at which they're doing a fine job. They only flatted a couple times over their lifespan and that was towards the end. I won't be buying another set because they're just not fast enough. Their rolling resistance is high compared to similarly priced tires, both in numerous tests you can find online and what I felt on the roads. Gp4000Ss, GP Supersonics, Vittoria Corsa CX and SL, Veloflex Corsa, and Bontrager R3 and R4 are all noticeably faster tires that don't give up much, or anything, in flat prevention or handling to the Pro4s. If you can get them for a really good price and your intent is to use them as a training or bad weather tire then they could be useful. Otherwise there are better tires out there.
Every person I know riding these tires flatted frequently and often last year. Probably 10 times the flat frequency of Schwalbe One, Vittoria Corsa, and Conti Grand Prix on the same roads at the same time.
I just bought a set and never had so many flats in one day, I had the PR04 Endurance and never had to worry about a flat. they roll fast but punctures spoil your ride, never buy them again. Lasted less that 200 miles
These tires handles the road very well, good tractions and rides very smooth. not very reliable. i did a century on them with no problem. The next day I wanted to do a short ride, i realized that i had a flat and a huge gash on the side. i only put about 200 miles on them before i retired them. the worse tires i have ever owned
Very nice tires as far as rolling resistance but if you are like me and ride 5,000 miles per year, they just don't last very long. So you can buy more durable tires or buy many of these and replace them often.
I bought these tires 3 weeks ago and have had 3 flats. Everything sticks to them- It's as if they're made of glue. They hug the road and ride like a dream but I've been riding for decades and never had this many flats with a set of tires.
I ride a lot of chip seal as well as come across gravel roads and gravel debris and I've been surprised at how well these tires have held up. I went with the 25s and run 80psi in front and 90 in the back (165lbs). They're grippy, comfortable and so far, I've been able to load up the miles with confidence..
Last season, I was disappointed with the Conti Grand Prix's I purchased (I tore them open in short order) so this year, I went with these along with the $5 Road Hazard. Knock on wood - I'm sticking with this set up.
These tires ride smooth and sticky. I put 2400 miles on them before the rear got so square that it started to show bare threads. I use them pretty hard too lots of long rides on Dirty 30, occasional gravel, and unforgiving commuting.
The only complaints I have are really compromises that Michelin made. These tires have great traction because the compound is pretty soft. While my tires lasted 2k miles, there were LOTS of deep gashes that exposedcut through threads - I probably should have replaced the rear sooner. Likewise the tire rides so smooth because the 25s actually measure 27.5mm 100psi. As long as you know what you're buying they're fantastic.
Fast, durable, great tire for the money
These tires are amazing, only have about 100 miles on them, but from day one I was shocked. The smoothest tire I have ridden on, the best grip I have experienced! Not sure what the longevity of the tire will be, but at this point I could care less, the ride is sublime and they spin very fast, the same or faster then GP4000's, but much better ride, just a much better tire overall!! Some streets in Portland are pretty messed up, to the point where I was literally being bumped all over the place, loosing grip on the hoods even, now my bike rolls over all of it like I have huge cruiser tires on my race bike, its that much of a difference. The last comparison was against my winter tires (Conti Ultra 2's) This tire is a winner and will be sporting these through winters from now on!
I decided to give these a try after riding Conti 4000s last season. I really like this tire. Durable, light, and rides really nice. I like the Conti's, but I think this is a better value.
I have used Michelin Pro4 Service Course for 2 years now and love them! Smooth ride and very few flats. Pro 4's handles well in the rain. Very dependable tires.
I use the Tires to train for Triathlon. Their soft, corner great and last.
Anyone who knows much about tires is aware of the fact that one can't have it all. Individual riders have to make choices about what characteristics they most value and which are less important. If, like me, you value traction and ride quality over longevity and puncture resistance, this may well be the tire for you. I definitely get more rear flats with this when compared to the GP4000sii. I'm willing to take that trade, as the ride is far superior to the Conti. I do a lot of VERY steep climbing and VERY fast descending on very smooth, clean roads. For me, this is the best tire for these purposes. I do sometimes run this tire up front and the Endurance version on the rear. It still feels nicer than the Conti and resists flats compared to the Service Course. I ran the GP for many years, switched to this for a couple years, and just recently tried the Schwalbe One and GP4000sii again to remind myself why I left it. I'm back to the Pro4sc in a 25mm (which is 28 on my slightly wide rims.) I also think it's one of the best looking tires out there, as it's very subtle. I hate the tread on the GP4000, which, in my opinion, serves only to collect dirt.
After years of using Conti GP 4000 S and then the new version GP 4000 S2, I have converted to the Mich Pro4 SC. These are a great value. They are light enough. They feel nice. They come in 25 mm (Why don't more tires come in the new industry standard??) I can afford three sets every season.
Training and racing because there's a lot riding on my tires!
Just a great tire I've been using many years. Tried others and end up with problems.
Great tires for race and everyday riding. I now only use the black as I've found in the past that the color sidewalls sometimes get soft and gummy, and mess up the rims.
Great tire, expect a full season from a set, the sidewalks will crack, use them as a race tire.
When these tires go on sale they are second to none in the marketplace for performance tires and I always find it amusing that those die hards on Continentals are blind to the fact and in doing so miss out on a great tire and great savings. Oh well, yet another case of pearls before the swine. Great riding, as puncture resistant as any other tire can claim to be in our abysmal Oregon road/roadside conditions and long lasting with me more often than not getting 2-3000 miles out of a pair barring some major debris catastrophe ....a very good thing as the sales seem widely spaced on these tires vs other brands.
