Tyres Ageing - When are they too old
Discussion
Is it for racing or for fun?
I have run through several sets of Pilot sport cup 1 in an odd dimension 205/50 15", i bought a big pile of used ones from a racing team. They were both old and heat cycled. They worked well anyway, be very careful the first laps if they are second hand as you need to rub of the surface rubber (They were slippery as hell for the first lap). But after the first session they worked well. I later got a fresh set of the same tyres, they were maybe a bit faster with a bit more grip but for a track day it wouldnt matter. Those tyres were several years old.
Only risk I see is if they had been stored in a cold place, then you can get cracks and other nasty stuff. Rcomps should always be stored at + degrees.

Thanks for the reply's, yes they are brand new still in the wrapper and never fitted.
and no budding F1 team here, just looking for a capable wet weather tyre for a 7 type hayabusa powered kitcar for our glorious Scottish summers.
Polley Motorsport and the likes of Demon Tweeks want £180 each
This guy on eBay wants £200 for set of 4

I've got a set of 10 year old tyres for my road legal track car;
they only get used very sporadically (annual MOT etc.) and so look excellent.
I tried them last year on a very wet trackday when I thought that they might cope
better with standing water than my semi-slicks; they were absolutely hopeless.

I'm a fan of the RS3 but is this for use on trackdays that are wet? For trackdays that might turn wet? For only road use? For all three?
Have you considered the Nankang NS-2R? Great tyre in the dry, even better when you consider their cost. Full 7mm tread depth. Plus a B rating for wet weather. I've used them on my TVRs in very wet / monsoon type weather and they have performed great.

The issue with old tyres is degradation of the casing caused by exposure to UV radiation (sunlight). Therefore where the vehicle is used and stored has a major effect on what age is acceptable. If kept outside in a hot climate the life will be a lot less than in a cooler climate and kept in a dark garage.

A 10yo tyre is like a 60yo man. Yes, they work, but not very well.
According to this news article some 80 year old men work like some 20 year olds.http://www.bbc.co.uk/news/health-43308729
Michelin state that 10 years is the limit as far as age goes

Road tyres should not be on a car for more than 6 years owing to sun/cold degradation
If sat on a car they can also flat spot if not over inflated or turned on a regular basis if car not used often
All tyres now have a small oval window on the side wall with 4 numbers in it.
If it says 2315 that would mean the tyre was made in the 23rd week of 2015......If I was buying a car second hand it is one of the first things you should look for as you could negotiate that into your buying price if all are over 6 years old. They would also be starting to crack.
I wouldn't buy a car with less than 3mm tread across the whole width....cause you will need new ones soon, and they provide less grip (road tyres...not track tyres)
You have 4 corners of your car in contact with the road, with the footprint of about a large envelope, so not a lot down there......between you and a wall/tree etc... buy the best you can afford......do you know the history of the tyre...person you are buying from? has any had a puncture? if so how many? my local tyre place will not repair a 3rd puncture and tells you to buy a new one
I don't know about track tyres....but I know what I will not put on a road car....hope this helps?
