Hi NG.

I have a Volvo v40 2002 (purchased medio 2001)

I have summer and winter tyre and have totaly driven 36000 km.

Tyre type, Kleber 185/65x15T is stored in cellar with windows.

Depends, I don't go by age so much as condition. If the tire is well
worn or the sidewall is cracking don't use it, if it looks to be in good
shape, go for it.

Hi James.

Thanks for your advise.
My tyre looks and feels nearly as new, so I will use them this winter too.

You shouldn't use a tyre more than 5 years old. It might look OK, but
rubber is attacked by oxygen, it makes the rubber harder and more
brittle - the same effect as over curing it.

If they look and feel new I wouldn't worry about it, just watch for
cracks forming on the sidewall. If they start to get tired looking
replace them.

I used to work for Michelin and drove on company tyres. All tyres were
changed and scrapped off after 5years, even the unused spare. A tyre
might look good, but the composition of the rubber changes and becomes
brittle with age. The first crack might appear when the tyre is under
stress and cause it to collapse completely.

To my knowledge the tyres do not work after 3 years, where you bought them
for.
After 3 year the rubber gets too hard and the benefit over sommer tyres has
gone.
I drive a V70-II
