Sport Cup shelf life
 

Hi

I can get 2 new rear Cups at a good price but the production date is middle 2003, are they too old?

Ive been looking into this and the top tyre manufacturers say about 6 years is the life of a tyre,after this they start to go hard and brittle and are unsafe.So I would think after 9 years they have had it;)

Hey Neil

how much you want for them, i could be interested provided you are not in johies?

Id guess they would be ok for road use. I ran 2003 ones a couple of years ago and they were fine. If you are going to venture out onto track then id say get fresh ones.

BMW is selling 2003 cups on ebay :wink:

Depends how they've been stored, if they have been away from direct sunlight and extreme temperatures, they will have a better chance of being ok. I'm sure Michelin will have good ozone protectant bulit into their compounds.

Whereabouts? Sorry, tried searching for them but no luck, :bigcry:

I am, where are you from?

I will most probably not use it for track but i might be doing a few higspeed runs, and that worries me more... Half price but maybe not a good idea.

i dont think any issues with safety on older tyres, just that rubber gets a bit hard

if you look at all the supercar owners i bet most have on original tyres as cars do so few miles, and no issues
