Conti GP5000 clinchers

My first pair of Conti 5000's lasted 2000 miles and I was sold. Then I got a sidewall flat, so I ordered another. Sidewall flat, ordered another. Third side wall flat within two months and I'm done with the clincher version. I'm onto the tubeless version and I hope I have better luck.

Regular pricing seems rather steep but I was wondering what is a good sale price for these and would you recommend running them tubeless? Probably going with 28mm for mostly road and some hard pack gravel. TIA...

I was seeing $75 for a pair and $90/pair tubeless on the British website.

Just purchase a set of 25mm from PBK. $75.00 plus shipping.
I have just as much trouble mounting these as I did the 4000sII's.
I felt like the 5000's had higher rolling resistance than 4000's at first. Later, after a couple rides I was unsure of that. Maybe I had higher than fair expectations, and that squewed my perception.
They also seemed to inflate to whatever the 4000's were size wise. My brake calipers would have told me if they were larger.

Here's a warning with the GP5000. I've already had 2 flats on mine since September, and I usually don't get flats on my road bike which has always had GP4000 on them.

Punctures? I haven't had any punctures on two sets of GP5Ks, only flats were pinch flats from nailing potholes at speed in a group. As always, ymmv. But I don't think the GP5Ks are any more puncture prone than GP4Ks (BRR rates them a 10 vs 11 for the 4K for puncture resistance).

I have some 2800km on my 23/25 combination set of GP5000 clinchers, one puncture so far (picked up this huge nail in the middle of an intersection, was over three inches long, luckily I put frame saver tape on the back of the downtube or it would have gouged it pretty badly), my impressions are very good. They still look like they're in very good shape, too.

Could not mount new Continental GP5000 on new carbon wheels; not even with tire levers. So I had to use my old GP4000 II using the tire lever. Have you guys had any issues? Any tips for mounting GP5000.

Make sure the tires are not cold. IN the winter put them on a warm spot in the house.

They mounted the same for me as the 4000SII, so it’s puzzling you couldn’t get it on. Maybe even a little easier.

Now have @ 800 miles on my first set. No flats or cuts so far. Ride quality is good I can't tell the difference between these and the 4000s they feel the same. Hard to tell what the longevity will be- typical for me the rear is worn a little and the front looks almost new. Re. the problems people are having mounting them they went on my Boyd 44s very easy just keep the beads in the center groove as much as possible & put a little air in the tube to give it some shape.

I used GP4000 and later GP4000s-II for years. I used them in 23mm, 25mm, and later 28mm sizes. The 28mm tires measured 31mm on my bike, and barely cleared the chainstays. GP4000sII tires have been great though, and I could continue using them happily.
However, when I wore out my most recent set I went to GP5000 tires instead. I got them in the 28mm size and was pleased to discover they do run truer to size. They measure 27-28mm on my wheelset (Fulcrum Racing Quattro 4).
Any evidence about flats / puncture resistance would be anecdotal at best. But for me, I've only had one flat with my GP5000s in about a thousand miles. On the other hand I seemed to average one flat every 300-400 miles on my GP4000sII tires. I'm a sample size of one, so it's not really a good metric. But they do seem pretty reliable to me. I doubt that I could judge accurately whether they roll better than the GP4000sII. Data on websites says they do. But again despite me being a sample size of one, and despite the confirmation bias implicit in wanting to like the thing you spent money on, I am happy with them, and find them to handle very well.
So I do consider them to be a great replacement for, and even upgrade to the GP4000sII. I'm happy to run them on my road bike.
(On my hybrid/commuter I'm pretty happy with GP4Season 32mm tires)

I have been using GPs since, well, there was only one version. Contis' have always mounted easier than any other tire that I have used. And after they have been on for any time, if you have to remove and remount (flats), they mount even easier once stretched out.

Interesting - for me they're the tightest tire by far. The Michelin P4E and Hutchinson 11Storm are both laughably easy by comparison.

I liked mine at first, but not so much now. Maybe it is bad luck, but I have had several flats now in only 1k miles. They are also wearing as fast as the Vittoria Corsa G+ they replaced, which never flatted and cornered better. The rear is cut up quite a bit through the cords and I need to replace it already. I ride the same roads regularly, and these have been the least durable tire I have used so far.

There is in fact substantial evidence that roller testing is inadequate, or just inaccurate to real riding. Specifically, it fails to match Josh Poertner's real-world testing, in which increasing pressure does not result in a monotonic reduction in RR. In fact, the linear nature of the BRR testing makes me question the overall validity. It's a prime example of a system that generates a number being taken as gospel, despite shaky evidence for it.
That said I've never liked Rubinos, but whatevs. They just give me way too many flats.
