After approx. 200 miles these tires are working as expected. Traction seems fine, seem to be durable, resistance is minimal.
I purchased 2 of the Michelin Pro4's and one of the tires is GREAT...the other has gone through 3 Tubes already 2 tubes while just standing on its own and not riding, the other while riding. For some reason the tire does not clinch to the rim by the stem and lifts when inflated...this causes the tube to be exposed and eventually a blow out. I am looking to give it another try...but my cheap Serfas tires survived 2000 miles without any issues at all and I am thinking I should just return to those.
Great tires have a couple thousand KM on them no flats which is great on the lousy road conditions in Quebec. Good grip in the corners and all in all I am very satisfied.
I have used Michelin Carbon Kyrlons for the past couple of years and these tire feel much better (comfortable). Part of that might be that I have also switched to a 25mm width. This last winter I used Gator Skins but unfortunately I ordered the wire bead. So the Pro4s appear to take less effort.
I have on hill I descend hit 40 mph into a smooth 90 degree turn. These tires give a lot of confidence under that circumstance.
I only have used them a couple of hundred miles so I have no idea on the wear.
These tires have a very good life with little sacrifice in performance. I ride year round putting on about 8,000 miles. I am pretty rough on tires and I am impressed that these last a full year of riding. These tires even with several cuts from metal and glass last and wont leave you road side because of a tire failure. I give my highest recommendation to these tires as a training tire.
Running the 25c on our tandem at 120 psi. We are always looking for a better tire. This is the best so far. Very resistant to cutting, yet holds well in the wet and rolls fast. That's a tough combination to find. Would make a very good distance tire on a single at a lower pressure.
If you need a tough training tire that rolls fast enough, handles well, and gives you 1500 miles of uninterrupted use, grab these tires (Background I'm 180 lbs, average 4-500 miles a month in Eastern Pennsylvania, and ride fast enough, with some hills, sprints, and hard TT efforts. I don't race anymore but if I did I'd leave these tires on for training races).
I've been a Vredestein snob, but the Michelin Pro4 Endurance has won me over. While it doesn't quite match the Vred's slick feel, it still handles and rolls well. It's a solid, fast tire. It even mounts easily. I can wholeheartedly recommend these tires to any road cyclist.
No flats so far (300 miles) at 205 lbs. I would buy again at the discounted price. Look sweet. Handles well, grippy. Not the fastest tire, but decent. It's fast though if you consider no flats.
I have been using the Michelin Pro4 and its predecessor for over seven years now, and love the durablity, handling and even the red stripe that matches my bike. Training in any conditions and triathlons are all within my range of activities. My annual fall tire change has become somewhat of a ritual, in with the new tire and out with the old! It would be nice if there were a way to recycle bike tires, because I hate to toss these things in the trash.
long time road rider and have learned over the miles and years you don't cheese out on buying good tires
Great tires, I pump it up to 115psi and go.
I have already put 500 miles on my 2 Michelin PRO4 Endurance tires. I haven't had any problems with the tires. Rather, compared to my old Hutchinson Equinox tires, they give me a smoother ride, and since the recommended tire pressure (114 psi) for my weight is higher than the Hutchinson tires I had (105 psi), there is less rolling resistance and, therefore, adds a bit more to the speed with the same effort. Now, the only thing I'm waiting to see with the Michelin tires is whether they last as long as my old Hutchinson Equinox tires which have approximately 3000 miles on them and are still good to be used as spares. The Michelins are installed on my Tommaso Velocita road bike, and I use my bike as a workout tool putting from 20 - 30 miles per ride, 5 to 6 times per week on the average.
I use this tire on the mountain roads of Colorado. I wanted a tire that can handle the harsh road conditions typical of this area. After 400 miles, the Pro4 Endurance has been a great wearing and riding tire. Michelin continues to make a quality product.
I ride 100 miles per week in the Burbank, Glendale, Montrose area of California.
I am glad to see this replacement to the Krylion back from Michelin. The Pro 4 endurance has the puncture resistance I need for long distance tandem racing, equal to the gators, but with a better rolling feel for speed. The tread surface is not as durable to cuts and they wear more quickly compared to the Gators. Requiring me to replace them a bit more frequently. But for me, a racing tire that I don't need to worry about flats mid-event, makes the pro 4 endurance a great option.
This particular tire has held up extremely well within the city for a regular 3x week commute of 30 miles. I do not sacrifice great feel for the road and get great puncture resistance compared to less expensive tires. Since going to the Michelin 4, I have not experienced a flat in the last year.
I go through two or three of these every year... they wear out because I put A LOT of miles on them. Other tires seem to flat more and can't handle the sharp basalt gravel we get from chip-seal and paving operations. The rubber compound is softer than most durable tires which makes them feel supple and they grip really well in the wet.... I have ridden them in ice which I do not recommend even though they performed remarkably well! They wear a bit quicker because of the soft compound but for my money it is worth it for the supple ride and the amazing grip in wet. The other soft compound tires I have tried seem to flat constantly. They found that sweet spot of soft, supple ride, good grip, durability and fairly low weight. I run them until most of the rubber is gone, have virtually no flats and happily buy another set....
I ride most of my miles on chip sealed roads. I'm getting 2500-3000 miles on my rear tires and more on the front. I have had zero flats or problems with these tires. I ride around 7000 miles a year.
I had the predecessor Krylon and got about 2500 to 3000 miles on those tires. I now have about 600 miles on the new tire and it apears to be working just as well as the predecessor. Saw no issues with flats or cuts. New tire is lighter so don't expect to get quite as many miles on these. Use tires for training and road racing, ride just over 6000 miles a year.
Use the tires for long training rides over many rough road conditions.
Sounds like the base of the valve is getting underneath the tire and pushing the bead out of place. One thing to try is seating that portion of the tire first to help get the base of the valve to sit inside the tire, rather than under the bead.
We've been in touch with you about this issue and, in addition to our troubleshooting tips, it might be a good idea to visit a local shop to ensure that your rim is in good shape and that you are seating the bead properly.
Thanks,
