Tyres query

[funboxster]

I had my front tyres replaced on my 2016 DB11 recently, as there was cracking in the treads and one of the tyres was an original.

I decided to check over my rears, which were replaced by my local AM dealer in November 2018 and still have 5mm of tread on them. I was surprised to see the date stamp of 0317, which, as I understand it, indicates they were manufactured wk 3 of 2017? I fully appreciate tyres aren't made one day and fitted the next and they can be stored, but 22 months seems excessive, especially, as I understand it, they should be replaced after five years, based on manufacture?

I have queried this with the dealer who is going to investigate, but I would be interested in feedback please.

According to Michelin tyres should be inspected after 5 years of use and replaced 10 years after manufacture.

According to blackcircles tyres are considered new up to 5 years from date of manufacture:

Not sure I would be happy with new tyres manufactured 5 years previously.

Thanks Scrump for your input and the links. I've emailed Bridgestone for their input as well.

If a tyre has been stored on a shelf at a dealership for a year or two prior to being fitted, would this be a problem?

If it's outside storage in all weathers then I see a problem however, in a dealership, undercover in ambient conditions ... I don't see a problem.

Having said this, I would expect a tyre to be reasonably new as in close to date of manufacture when spending several hundred quid on them.

I agree, somewhere in the chain, there has to be an element of storage. The dealer has confirmed to me they buy from a group supplier, who then purchases direct from Bridgestone. So, either the supplier has them in storage, or Bridgestone.

My key point is while stored, surely the clock is ticking on their useful life? Anyway, I'll be interested to see what Bridgestone CS has to say.

I wouldn’t say it’s abnormal that

You are worrying for nothing.

They would needed to have been rotated whilst in storage, or the plasticisers etc would have started migrate to the lowest points over time under gravity.

Continental also have a 10 year maximum tyre age from manufacture.

Personally, I would kick up a fuss if my situation demanded it. ie. I hardly use my car, its likely I would replace them at the 10 year mark with half the tread remaining. Then I’ve missed out on almost 2 years worth of use. However, If I was doing 15k miles a year and would likely wear them to their legal indicators after a couple of years, I wouldn’t bother moaning.
