My 5 series Touring is now nearly six years old, but has done a low mileage. I am following the BMW service plan and obviously the car has been MOT'd and as part of this tyre tread has been checked and signed off. However obviously weathering must impact the life of the tyres. As the car is six years, how much longer should I keep them?
Any thoughts appreciated

U/V radiation seems to be the problem. Related discussion here:-

Not 100% relevant to your question but of interest, I hope!

Personally as it has just had an mot and tester if he did his job right will have inspected tyres for cuts abrassions and cracking failed to see anything, then i would carry on using them with no worries.
Make sure they have correct pressure in though.

"in June 2005, Ford and GM admitted that tyres older than 6 years posed a hazard (whether used or not) and from their 2006 model year onwards, started printing warnings to this effect in their drivers handbooks for all their vehicles."
US has a D.O.T. number on tyres giving date of manufacture - don't know if there is an EU equivalent.

I found this on the AA website:-
Is there an age limit on tyres?
Tyre age is a factor that must be considered independently of tread depth. Tyres do degrade naturally over time with the rate and severity of degradation depending on the weather, particularly heat/sunlight and rain, and the amount of exposure to the weather.
This is a more common problem on caravans and other occasionally used vehicles than it is on cars though you will still see UV cracking of the sidewalls on a low mileage car, particularly if parked outside all year round.
The British Rubber Manufacturer's Association advises that 10 years should be the age limit on tyres in service, though that will be if stored in ideal conditions - off the vehicle, at even temperature and out of direct sunlight. Expect to see UV cracking start to appear on tyres at four to five years if parked outside. As the cracking becomes more severe, tyres should be renewed irrespective of how much tread remains.
It sounds like my question is timely. My car will shortly be service with BMW. Presumably it would be insane to have them change the tyres. Any advice on places with best prices
Thanks

Ask the BMW dealer anyway. I've had some very competitive quotes from main dealers for tyre changes, exhaust replacements as well for that matter. OK, I've also had some "you must be joking" quotes as well...

Don`t know about any other Costco depots but at the one in Leeds, although they sell Michelin, they will if asked obtain any make of tyre you ask for as long as you don`t mind waiting a few days for delivery.

Surely the tyres are not in service if the are in storage and not fitted.

My understanding was about 10 years max and mainly because of UV.
That is why the SUV's have tyre covers when the spare is on the back - to protect it from UV rays.

My brother runs a chemical plant that produces the anti-oxidants that go into (a significant proportion of the world's) car tyres. He refuses to drive on tyres over six years old.
I am inclined to be somewhat more cavalier.

Also, Caveat emptor when buying 'new' tyres. Check the dates - some of those 'specials' may just be specials because they are old stock which has been sitting on the shelves for 18 months or longer...
