Continental GP 5000 is here

Initial European pricing is 75euro for the tubeless GP5000-TL and 63euro for the clincher, so not a cheap tyre. Comes in 23mm > 32mm.

Should be some good end-of-stock sales around the place soon then..."As a running change, Continental has ended production of the GP 4000 for several months, and you will only find the new GP 5000 once existing stock in the market is exhausted..."

Tubeless in 25, 28 and 32mm.
20% improved puncture protection and 12% less rolling resistance compared to GP4000 are the official claims.

Car tyres have a lifespan and if you get new car tyres that have already been sitting in the racks for 1 or 2 years, that's not the best (as I understand). So how many GP 4000's can I buy and stockpile for how long?

I've always been led to believe that if stored in a dry, dark place then 3-4 years.AUbicycles wrote:Speculating on the GP 4000's - how long will they keep?

I still have a 23mm first generation GP4000 that's probably about five years old.AUbicycles wrote:Speculating on the GP 4000's - how long will they keep?
Still in it's box but wrapped in a ziplock plastic bag and stored in the dark.
I fitted one of a pair of the above 18 months ago, no problems. The rubber is still supple and no sign of perishing. Remains to be seen if i get my typical 7000-8000km mileage from them.
I mentioned in a different thread my impressive 12,000km mileage from a pair of 28mm GP4000 II's. I fitted them to a new bike in April 2015. They've just about had the gong.

I would add, in a sealed bag or box with minimal airspace. I used to do this for R/C model car tyres and it makes a massive difference to keeping them fresh, which was immediately noticeable on the stopwatch. So I do the same with my bike tyres.10speedsemiracer wrote:I've always been led to believe that if stored in a dry, dark place then 3-4 years.AUbicycles wrote:Speculating on the GP 4000's - how long will they keep?

Same base theory.

Bike tyres are not generating the heat to require warmers, they just need a very soft compound from the get go to generate grip.

Generally car tyres have a life span of 10yrs + if they being used or around 7yrs if just sitting on the shelf,AUbicycles wrote:Speculating on the GP 4000's - how long will they keep?

Car tyres are supposed to be fitted within 5 years. Personally I'd be happy to store tyres (cool and dark environment) for a few years.AUbicycles wrote:Speculating on the GP 4000's - how long will they keep?

The main problem with car tyres is the compound hardens slowly with age, which reduces grip especially in the wet. It is not really a big problem for road cars, but can make a huge difference in race cars. There is a separate problem of rubber cracking, particularly on sidewalls, as tyres age. However, this is more related to environmental exposure in use, and does not really occur in well stored unused tyres.
Relevance to bike tyres? I don't know. However, I don't think there are any markers indicating date of manufacture? So if you buy tyres, you don't know if they have been sitting around on the shelf already for several years.
I wouldn't have any qualms using bike tyres that had been well stored for a few years, ie out of the sun, and not exposed to extreme temperatures

On the topic of old car tyres.
I had a set of very aggressive off-road tyres (not the best in the wet as new) that got to about 10 years old.
They became so hard they didn't seem to wear anymore, and were absolutely dangerous in the wet. Still ok in the dry though.
Bike tyres I imagine would be similar, all may seem ok on an older tyre until you meet that white line while cornering in the wet one day.
I had an accident after cutting the sidewall of my front GP4000, in the interest of time I quickly chucked on an old original giant tyre I had lying around for the next ride. Happened to be wet and I went dont like a sack of potatos!
