I've been riding the Continental 5000's and 4000's. New purchase change due to how hard it is to install a Continental tubeless 5000. The ride is much smoother and so is the handling. Wasn't looking to change but the installation on the Continental was nearly impossible.

Just wanted to give anyone a heads up if you are buying these for hookless rims. It specifically states on the side of the tire that it's not compatible with hookless rims. I was originally told they would work. Ended up returning them.

I've put a couple hundred sporadic miles on these before I put them through a long, continuous haul in a 630 mile race in MN. The terrain was quite mixed. Trails had a lot of bumps and cracks and there were many miles of nasty pavement. These tires aren't supple or very comfy but they did the job well running them tubeless. It is important to note that the pressure recommendations vary between tubeless and tubed configurations. On the sidewall for mine says, "Min. 72 psi - Max 101 psi with Inner tube. Min. 58 psi - Max 87 psi tubeless. I ran 28c on Hunt Aero Wide 34's. The inner rim width is 20 mm. The overall tire width on this combo comes to 30 mm. I had no issues with the bead seating or sealant leakage. Psi was 74 on both tires for the race. They rolled, cornered and brake nice in dry and when I was caught in a thunder storm, they did not disappoint. These rolled and turned with no loss in confidence. I did, however suffer an inescapable puncture at mile 220 in the middle of the night and in the rain. I hit a small, sharp rock on a descent and buy the sound of it I knew it was bad. I had a nice 7 mm slice on the sidewall along with a dinged rim. I threw in an Aerothan tube, booted it with a $1 bill, the bead seated, inflated to 60 psi and it held pressure & integrity for 410 more miles. I am, indeed a fan of these tires. I will continue to run these on my work commutes, city rides and long distance road adventures.

Excellent tire, Tubeless setup and easy install on my Campagnolo WTO wheels. Great handling tire and very puncture resistant due to the kevlar belt. A little heavier than some but works great for a training tire and so far holding up on my glass/debris covered roads.

This wasn't my first wreck. When you cycle you expect there will be hazards that happen or errors made that cause one. I keep my bikes in good shape and follow the recommended tire pressure guidelines. In this case I filled to 80 psi (73-87 recommended) prior to the ride. This bike has Shimano Ultegra RS500 Wheels.
The tires were about a year old but only 2000 or so mile on them. I had about 150 mile since the last sealant topping off.
I was on a familiar route and making a sharp turn that started at about 20 mph and historically would have ended at 17 or so, but instead left me banging into and sliding across concrete.
5 days later I sit all bandaged up waiting to get back on a bike, except I'm going back to tubes with other tires. There is no reason I can think of that they should have failed.
Maybe the tire/wheel tolerances didn't match up well. My life is too important to experiment with that issue. I loved the miles I got but, under the circumstances, convincing me to go tubeless again will take some herculaneum effort.

I bought these last year to upgrade from the stock Mavic tubeless tires because I read online that they have decent puncture protection. They are so tough to mount, that I thought I was going to snap my carbon rim just getting both beads onto the rim. I've rode on it for about 500-800 miles now, and it's been punctured twice already. Once from a random metal wire about the same size as a paperclip and the second from an industrial staple. If it weren't for the sealant in my wheels, I would have easily had a bad day and ruined rims.

All the people complaining about these tires have one thing in common - they attempted to mount them tubeless. Themselves. My experience has been the opposite (I mounted them with tubes; I still don’t understand why someone would mount a road tire tubeless). I rode continental Grand Prix four seasons for the past four years until discovering these babies. They’re every bit as fast (possibly faster?) and have even better puncture protection. They’re also super grippy around corners, even on frozen pavement. I ride around 1500 miles/month (you read that right) around nyc & the surrounding area, and haven’t had a flat yet since installing them on my surly midnight special a year ago. I use the 700x35 version and can’t remember the last time I swerved to miss a field or broken glass, a pothole, or any of the other rotten objects that I encounter several hundred times a day on the streets of nyc. These tires are simply as good as it gets. They are nuke-proof, fast and supple. I cannot recommend them highly enough.

I rode these for 2k mi after a series of flats with my conti 4000 II made my decision to go tubeless. They rode OK, but were not as smooth or grippy as the conti's they replaced. They certainly fixed the flat issue 100%. OTH, I was not thrilled with the advanced wear on the rear tire. I would guess I have maybe another 1k mi before it's used up.... That is if it could be mounted again. After a long winter of no use(MTB time) , both tires were flat. No problem, I'll just pull them off, and I clean out the old dry sealant as best as possible and reinstall. That worked fine for the front tire, but not at all for the rear. The tire refuses to latch. I tried heating it, doing the tube trick and even going to a shop that had a more powerful compressor than I have (forget using a hand pump). The issue appears to be that the side walls have stiffened and possibly the tire bead has loosened so that no matter how much pressure is applied, the tire leaks all the pressure without moving toward the side of the rim. After dozens of attempts using a lot of soapy water, sealant, different air caps, 2 different compressors I have given up and ordered a pair of conti 5000's which were the tires I wanted in the first place but were unavailable in 700 x 28 at the time I was dealing with that in rash (5x in 2 days) of flats. These are very easy to install on my Reynolds Assault LE rims, easier than the tubed conti 4000's they replaced which might be the problem. If this issue hadn't occurred, l would have bought another tire in a couple of months and moved the front to the rear. Instead I'm forced to spend twice as much, junk both perelli's and move on. A wasteful choice.

Mounted the 32's on a set of Stans Grails with no issuesI run between 40-60 psi and I'm 190 lb (I inflate to 60 psi and by the end of the week they are down to around 40). I've commuted on them for the last 6 months (~3k miles) through Baltimore MD industrial areas; LOTS of glass and debris. No flats that the sealant didn't handle and they have worn very well. They are a great training/commute/every day tire that will see you through thousands of miles. I haven't had to take them off the rim so I can't comment on bead stretch but I could see issues if you try to mount them on a different rim with a smaller effective bead diameter.

I have concerns about the safety of your Cinturato tires. I recently purchased a Pirelli Cinturato Velo 700*26 tire that can be set up tubeless. I read several reviews on this tire before purchasing and the only consistent comment was that they tend to run oversized, i.e. the 700*26 is closer to a 700*28. I set the tire up on a DT RR440 rim with no problems, and checked to see if it was indeed oversized. I measured the tire width at 25.7mm, which seems spot on for a 26. Fast forward a bit and I’ve done a few rides and put a little over 100 miles on the tire, when I notice it is starting to rub against the top of the wishbone brake bridge on my Time RXRS. The tire looked noticeably larger so I measured the width and it came in a 27.6mm, the only two reasons I can think of for this is maybe the casing stretched or the bead stretched. Anyways being I can’t use it on the rear I decide to try the front so I mount it on a Stans Alpha ZTR 340 fill it up to 100psi when the tire explodes off the rim. Yes, I now realize that Pirelli has two maximum psi ratings on the tire, one for tubeless one for tubed. I looked at the tire before mounting and saw max psi 116, and assumed 100 psi was safe, they list a max 87 psi for tubeless, the fact it blew off at 13 psi over is still scary. (Quick note: I have been running tubeless road almost since they first came out with no issues other than the occasion flat that sealant could not plug, I’ve put over 10,000 miles on this ZTR 340 rim mostly tubeless without an issue. However I’ve always stuck with Hutchinson tires in the past, with the exception of one IRC (it worked fine also)) The only reason I can think of for the Pirelli exploding off the rim is that the tire bead must have stretched, which I think would also explain the increase in width of the tire. If that is the case, and with the amount of comments on the Pirellis being oversize, it seems this could be an issue with all Pirelli Cinturato tires, maybe all Pirelli tires. In my opinion this is not a safe tire to run tubeless. I’m quite disappointed as I’ve had to purchase a new tire to replace it, and have a almost new Pirelli that I don’t feel safe using.

Mounted and held tubeless as expected. A bit shy of the claimed size and the power meter suggests they're pretty inefficient compared to others in the same size, but the bigger problem was bead stretch. I was shocked when I removed the tire to move to another wheel how loose it was on the rim compared to when I installed it. After removing I couldn't get it to mount on any tubeless rim that I own, and would have been pretty dang nervous if I had. Decided to just scrap it and get different tires. This is with the 32mm tire, 165 pound rider, toward the low end of the acceptable pressure range, and no more than 500 miles of riding.

I installed these tires tubeless on a set of DT Swiss PRC 1400 wheels. I mentally prepared for an epic failure, but both tires inflated on the first try with just a regular air pump. They have held pressure for a week and i have no issues so far.

I was excited for a good quality tire to use for my commute. I've been using Continental's and Zipp. They did mount easily, good on the road, the issue.......They will not hold air! They go flat within a week if not pumped up. My other tires on these same wheels I only ever topped them off with air, never needed to fill them up due to being flat. These must be inflated fully every week.
I will not buy these again and I would not want a friend to buy them.....

I know there is a lot of people saying road tubeless isn't the way to go, or that they have a lot of improvements to make to be good. Well, Pirelli did it, these tires are amazing, roll well, grip well, and honestly, for the weight are pretty fast once you do go tubeless. I got the 28mm for a disc road bike and i'd never use regular tires again. I've used many vittoria's and GP 4000 II and the Prilli's are hands down a more well rounded tire than the others. If you've been on the tubeless fence, these will bring you to the tubeless side for sure! and not a bad cost for tubeless tires.

Gravitated to these tires for its durability and tubeless ability. So far, they've held up quite well! Maybe not as supple or fast rolling as some, but for an all-weather, 4-season tire it's not too bad and it beats changing a flat on the side of the road with frozen hands. Sets up tubeless easy and I would definitely buy them again.

I have had 0 issues with flats with this tire but just got it. In many reviews online, tests indicate this is one of the most puncture resistant tubeless tires. You do compromise a bit of rolling resistance but who cares, i'm not on the side of the road changing a flat.

Got these to mount tubeless on my road bike. Got 28s. They were difficult to mount. Went on the rim easily, without tools, but that's when the 'fun' started. Couldn't get the bead pre-seated for the life of me. Had to remove valve stem and pray before the beads finally seated. Compressor mandatory! On the road, they are not as supple as the S-works tubeless I've been using. The ride is a bit harsher. But, and here's the real reason I tried these tires, they seem to be much more resistant to rock cuts than the other tubeless tires I've used. The cross-linked carbon in the tread seems to do what Pirelli claimed it would -- prevents cuts. I'm looking forward to seeing how these fair long term. At any rate, my confidence in them is growing with every ride, upon getting home and finding no cuts in the skin of the tires. So be patient mounting them (you'll really have no choice) and see if you don't think they're about the most evolved tubeless road tire available in terms of durability and resistance to cuts. Oh, almost forgot, the 28s sized up to 30.5 mm on my 21mm internal width rims. I'm running them at 90 psi, but am thinking about dropping down 5 psi, then 10 to see if the ride improves.
