The Rolling Resistance website also concludes that at 80psi 4000’s with latex tubes (which I use) have less RR than the 5000’s, they're also wider, have better puncture resistance (thread and sidewalk) and are lighter.

Ive near 5000km on a set (the back wheel looks to be squaring off now) and I've had 2 punctures (on the front)recently but that could be the surfaces ive been on. I have the GP5000's on the winter bike in a 32mm so not enough done on them to make a call... I was thinking on GP5000 for the summer bike to try it out but a bit more expensive so not sure now.

Bit of a thread resurrect here. I bought one of those GP4000 ten packs and have been steadily working my way through them on various bikes. Finally ran out and 4000's aren't to be had anywhere so I had no choice but to go the 5000.
Wow. All I have here in terms of data is my own perception, but they feel to me like the biggest performance upgrade I've ever done to a bike. They roll absolutely beautifully and feel really smooth and fast. I've a set of 25's on one bike and I've fitted 23's to my S2. They don't look like skinny 23's and they don't ride like I remember 23's to ride. They're really really excellent. Early days yet in terms of wear etc but happy days so far.
They are about as durable as toilet paper and pig tight. I bought a set then gave them away on here for free. I have 2 x €20 tyres on now that roll just as good and are far more durable. Thats my experience of gp 5000s.
Still the best grip I have experienced, I can lean into corners in Corkagh Park like I am a pro moto rider with knee pads. Durability seems to have improved from the first batches but still don't trust them like I did the GP4000s as a commuter / racer tyre but no punctures on my latest set and they have been on the bike for almost two years, albeit a lot less riding than usual as I have been using the CX bike for commuting a lot more.
They don't suit some rims - of course the rim manufacturers won't disclose that perspective at all so it's a bit of trial and error. If you try to put them on rims that don't behave with the GP5000 (Mavic USTs for example) then you'll face the same frustration as byrnem31 and it will probably colour your view of the tyre as a whole.
On a rim they behave with they are a suberb tyre - the pinnacle of Continental tyre development for racing and fast riding.
I wouldn't waste them on a commute or really expose them to year round use on our dirty winter roads - use the 4 Seasons tyre for that instead. Where these come into their own is on clean roads - wet or dry - where absolute progress is the goal.
Good to know. I'm just coming to the end of my stock of Continental Force and Attack pairs of tyres. Was thinking about trying the GP5000's. I see they are 35.99 in Alltricks - good price?
Yes. That's a good price in my experience
Its funny how much of a personal choice tyres are. I used to be a GP4000 man, but they kept on getting punctures and rips so I gave up on them. I don't think they are suited to Irish road. However on reflection it may be that they are just not suited to the heavier rider in conjunction with the average (poor) Irish road surfaces. I have since moved on to Specialized tires and have gone tubeless, and having a much happier experience..
State of the roads around Wicklow the last couple of weeks, I wouldn't want less that 4 seasons at the moment. I don't recall them being quite so bad other years. fwiw I've been lazy other years and left them on well into spring without really noticing.
I did like the 4000's, and only changed the front (after a tear with a puncture) to a 5000 and it seemed nicer rolling and grippy.
Apologies for the slight threadjack, and probably very silly question, but I didn't really think it was worth starting a new thread. For those who bought a 10 pack or a decent supply of tyres, where do you store them ? I've 5 GP 4 Seasons tyres, unopened, still in their little cardboard packages, for about a year now that I've just kept in a little plastic drawer unit in the garden shed. Obviously its dry but would be draughty/cold in winter - presumably there's no issues with tyres being stored like this ? Given tyres actually on a bike would be in the very same shed during the winter ?
I keep em in a press in the house. It's not something I'd be overly concerned about tbh. At the prices Cyclesuperstore charge for GP's I've no doubt but that they stay on their shelves unsold for years too! :).
Thanks for that !
Very true 😀. Although I hope CSS is a little warmer than my shed 😁😁!!
fwiw I hadn't even thought about it, and they stay in the shed! I've a few I swap around that a hung open from the roof, and haven't noticed any issues. I've assumed light would be more an issue that (low) temp.
That's gas. I must have about 15K km or more on my GP4000s (I can't even remember when I put them on) and the rear is only losing its wear indicators now. There's one small 5mm cut on the back, no other damage. Apart from a pinch flat and a few recent punctures caused by the rim hole being exposed by the tape I can't remember when I last punctured on them. And I'm no lightweight. Still a good bit left on the front so I'm going to move the front to the rear and put the GP that just arrived from Mantel (4 days from order to delivery) on the front.
EDIT: just checked my emails and found that I got them in May 2013 😯 I did Vätternrundan the following month so they must have been in use since then!
Yeah, it's amazing how different people can experience the same tyre. I'm like you, I got phenomenal long term use out of any GP4000's I ever fitted. A couple of times I refreshed tyres simply because I thought I should rather than because it was actually needed! I only recently went to do that on a bike and realised one of them was a 23 - it must have been on that front wheel for 7 years!
I've been using GP4000 exclusively since 2015 or so, and have primarily have used them on really poor condition back roads and they have been brilliant.
That's probably circa 40k km or so with typically a puncture a year. Yet in the last two 200 I rode in the last 5 weeks I've had 2 puncture per ride, and I haven't changed a thing. Sometimes your luck is out.
I'll attach some of the surfaces they have dealt with with minimal issues.
I've ridden them in 28mm and when measure on a 17.5mm internal width they measure 31mm. I hear the GP5000 meaure accurate or even small; has anyone experience of 30mm or 32mm Gp5000 clinchers on similar rims?
