Anyone seen this before?

[brythered92]

Hi all,

My front tyres on my e class Mercedes are appearing to be worn and cut along the outer edge of the tyre. Does anyone know if this is where the rubber is old or if it’s something like tracking / balance that could be causing this?

They're 11 years old?

Defiantly due to age

The cars 2018 how can you tell the age of the rubber?

Oh just saw the 2012 number! Is that the year of manufacture. Weird that they would put that on a 2018 car?

I don’t think that’s the date of manufacture, it’s usually a six digit number?

I don't think 2012 is the date of manufacture:

I was told by a tyre fitter that Avon/Cooper tyres are well known for age related cracking before other brands. What brand are these?

[brythered92]

These are Michelin

Aren't modern Mercedes cars notorious for tyre 'scrubbing'? Could be the result of unusual loads that process is putting on the tyres...

4 digit i thought (week/year e.g made today would have 1423 on them)
OP, could be tracking, what pressure are they? Or do you just rely on TPMS readings?
Are the rears same age but fine?

It is a 4 digit number.

First 2 digits represents the week built. Second 2 digits represent the year.

[Philvrs]

If you have any doubts, just buy a new pair.
Keep the old ones and list them on ebay, an amateur drifter could use them if they’re a popular size.

.. and it’s usually in its own ‘box’ not with another number. Re-check OP, and put an image up.

Probably a patent or regulatory number for that tyre design.

And possibly sun damage ,is the car parked in a garage or open air ?

Unless you're looking at classic cars at auctions where people never change them. 3 digits and a small triangle is the 1990s and I've seen just 3 digits, i.e. 1980s. In those cases, the year of the decade is the single digit at the end.

Yep, I doubt that they are 2012 tyres.

You are indeed correct.

Looks like an old tyre to me too. That said neither of those pictures show the age stamp. Look for something that says something like DOT XXXX XXXX 2517. As other have said, that would be 25th week of 2017
