Never used 4000's but currently have 5's and won't be buying again. Shocking to fit due to the snakeskin sidewall stuff they have, they have little give in them. As mentioned earlier they are not supple compared to a Vittoria corsa or similarly known race tyre. In terms of feel they ride similar to something like a Schwable Durano IMO. I've never bought Conti's before in about 10 years of road riding and given what I've previously read what expecting a fair bit different.
I changed one bike from Durano's to 5000's and I can tell you there is absolutely no comparison. 5000's are way more supple. Also I had no problems fitting mine, whereas duranos were a pig.
I'm wondering do you have the tubeless 5000 version by any chance? They have a much thicker sidewall construction than the non tubeless
Certain wheels make getting the tyres on tricky as well, my Fulcrum Racing Zero Competizione wheels are nasty for that until you learn the right way to fit the tyre, it's still a bit of a pain though. They are really great wheels though.

I thought the same when I fitted them and went and checked the box, they are the clinchers. I can fit Corsa's without a tyre lever, no chance with 5000's.

Yes, that is definitely the case, and not necessarily predictable. I have had tyres that are almost impossible to get on certain rims, but pop onto other rims easily. Yet a different tyre goes on both easily.

Recently swapped over to GP5s, previous set were Vittoria Coras, before that were the veloflex masters, all 25c.
Can confirm they were easily hand installed onto my Zipp 404s.

Someone's gotta say it. They went on my prime rr v3 wheels, by hand, pretty easily

I swear by GP clinchers and have yet to see much difference between 4000 and 5000.
Grip is amazing. They saved me from a 35kph face plant in the middle of the New England highway.
Took a new turn fast-ish and didnt see loose gravel. My front wheel went and i was gone for all money until it bit again at some crazy angle and i pulled upright.
Only caveat is riding nasty metal - the 4000 sidewalls are a little soft.

I've been rotating through all of the decent 25mm road tyres out of interest, and to be honest I can't really see much of a difference between any of them!
Have been through a fair few sets of Pirelli P Zeros, which seem fine. Though I have destroyed four rear tyres through a combination of mishaps and bad luck, and the GP5000 on as a replacement currently also seems fine. Hard to fit; but that may be my girly hands.
Have gone with Goodyear Eagle F1s on the new bike but mainly because they look cool. Will report back. I am suspicious that all modern decent road tyres are equally excellent and your user experience will come down to luck.

Please do report back on these, am very interested. Want to try a set out (mainly because they do look so cool..)

Used Cont4000's and now 5000's, both good tyres with minimal problems and
the 28mm's on my roadie get over some rough stuff (rail trails) etc at times.

I still like my Rubino Pros, good grip in the wet and roll okay, I didn't notice any difference between these and the Conti GP4000's, except in the wallet. Two for the price of one Conti.

Tried the 4000's and whilst they gripped, sidewalls were like paper.
Also dabbled with the GP 4Season's, and they were OK, but the really tough sidewalls made them 'firm.
Best compromise to date has been the Conti GrandPrix

That's been my experience as well with Conti GP4 etc.
Am a Vittoria Rubino fan for general road use, and they come in different flavours as well (Speed, Endurance and Control).

I like this site;
https://www.bicyclerollingresistance.co ... bike-tires
They seem a fan of Conti's and they certainly see a few different tyres.
Hope there isn't any cash inducement behind the results.
Done plenty of k's on gp contis from 3000 up to the current 5k tubeless I am running now.
Yeah they are pretty durable given the speed and grip available imo
Rubino pros were also good just wore quickly. Given the price you can get em for, that trade off in wear is worth it

I too have gone with Eagle F1s, going from GP4000s, and have found them a fantastic tyre. Roll well, fast, and so far no punctures or indeed much wear.

My only feedback so far is that the Eagle F1s were a little tricky to put on.
Though that could be my weak hands. Has anyone got any tricks or tools? I'm a bit worried that I'll have a flat at some stage and have to call for a lift because I can't fit the tyre.

FWIW, Bicycle Rolling Resistance review of the tubeless version:
https://www.bicyclerollingresistance.co ... 1-tubeless
We had high hopes the Goodyear Eagle F1 would be something special, but the reality is it doesn't stand a chance against the competition in our tests. Rolling resistance is quite high, tread puncture resistance slightly below the all-round average, weight isn't spectacular, tread width is also borderline for an all-round tire. The good parts are that it is very easy to inflate, holds air well, and the sidewalls are quite tough.
We rate this tire 3.0 out of 5 which is still recommended. We do think the Eagle F1 can be a good tire as long as you don't buy it with the expectation that this is one of the fastest road bike tires out there. The easy inflation with a floor pump is also something some manufacturers should look into.

^ Interesting. Coming from GP4000s I feel the F1s were definitely an improvement

Whilst it's all good to compare crr etc and great stats and info from sites like BRR, but my question is "can the average cycling enthusiast really tell the difference ?
Or is it the classic 'lebel influence' ?

For some reason every new set of tyres I get is much better than the old 'down to canvas' set I had before.
Strange that.
Honestly, I don't think there's going to be a huge amount of difference between GP5000/Pirelli P Zero/Goodyear Eagle or any of the other top line contenders.

I see the BRR reviews as a fairly objective review of some of the components that matter.
As mentioned here most top line tyres are fairly good.
I find it useful to see how durable, in terms of puncture resistance, various fast tyres are.
In terms of rolling resistance yeah I agree it is going to be pretty hard to pick 2-5 watts of resistance, when the overall drag at your limit may be 250 or 300 watts, or around whatever your ftp is.
I dislike getting punctures so don't want a tyre that is fast but not resistant to punctures.
I see it as a more objective measure than user opinion.

Are those tubeless or just normal clincher tyres?
I used to have difficulty putting S-Works Turbo (non cotton) tyres on the Fulcrum Racing Zero Competizione wheels. They were %^*#%^ things to put on. The trick was to keep the tyre seated as much as possible in the middle of the rim and to always seat the tyre around the valve area as the last step. Sometimes it would be tricky to get them to fit properly on the rim when inflating the tube as well. It would take a bit for them to lock in place.

Just the normal clinchers. I do tend to have problems anyway - I think my hands are actually pretty weak!
Needed two tyre levers, which I hate doing. Particularly on carbon rims. Did have one of these which helped:

It's just my nightmare to have a flat that I can't change. My wife will kill me when she has to pick me up.
