Would you replace all the tires?

Simply email the tyre manufacturer for the answer to this. Fact is no one here knows the answer, tyres dont have a sell by date and their life depends on many things UV etc.
manufacturer knows best :thumbsup:
Very good advice, OP. (And you'll find that tyres do have a sell-by date. It's 6 years.)
 
For areas not including Middle East and Africa , Bridgestone has a maximum service life of 10 years…subject to annual inspections :thumbsup:

Michelin says after 5 years you should have them inspected annually by a professional. Translation: they are potentially dangerous after 5 years but we advised you to get them checked and if you don't it's your fault when it goes wrong. If you did get them checked by a professional, then it's his fault for missing the fault.

After 10 years Michelin says you should replace them. Translation: definitely dangerous, we're so worried about liability that we don't think even having them checked out by a pro will be enough to protect us.
 
Steven, is it assumed or confirmed the tyres are 9-yr old OEs? Did anyone check the manufacturing date on them?

Most things have sell by dates.
I remember when I was in the Royal Navy. I was walking around the dockyard and noticed two enormous stabiliser bearings on palletts outside an engineering shop, about 1.5m in diameter. It had started to rain and as bearing steel rusts quickly I popped in to tell the lads. They said "dont worry mate they are past their sell by date they are going for scrap'!! They told me that the pair of them cost over £25k!!!
Point being that sell by dates are often bollox in regard to many items.
The six years you quote is a general figure - some maufacturers/countries state 4 years for high performance tyres - some state that the 'birth date' is irrelevant because the tyre is stored in a safe environment until dispatched to a vendor which could be months or longer for some tyres.
 
Thanks to all for the advice. I wound up buying the car today and the dealer took money off to cover the cost of new tires. 2014 (edit) with Cold Weather, M Sport, Premium Sound, Technology and Auto High Beam. Black Saphire with Black Kansas leather. 9k miles. Automatic and the 28i engine so did not get everything but this is quicker than I thought. Now just have to figure out which tire to put on. Bridgestone Potenza, Driveguard or the new Michelin Pilot Sport. Experiences and thoughts appreciated.
 
Picking up the car next Saturday. Dealer said it was professionally detailed - yea, right - so the dirt half way into the rim is proper? Don't hold much faith when I pick it up. Will get a proper detail once I make sure the car has no issues.

Maybe they got a solicitor, or accountant to do it! They wouldn't be lying then. :D

My daughter is an accountant and she would be unhappy with that statement - her cars are always spotless

Makes her a professional detailer then Sean. I am also a qualified accountant (a long time ago) but I know nowt about detailing! :D

Her car is typically cleaner than mine, she seems happy to spend 3 or 4 hours detailing it, me, 20 mins and job done but then I do get it done couple of times a year as my mate is a valeter

I guess the default tire on it is the Bridgestone Potenza. I'm in the US - if I wanted to stay with the run flats (I know, I know) is there any other option staying with the same size? Car has the M Sport package.

Thanks....

I'd definitely want new tyres, but would want a discount instead of letting the seller fit any old tat.

You don't say what size wheels you have which may affect your options, but if you want to keep run-flats I'd avoid the Bridgestone Potenzas like the plague!

I had them on two E86 Z4s (18") and an E90 3 Series (17") and they have limited grip in the wet plus appalling ride quality. :(

17" Continental run-flats and 17" Hankook winter run-flats on my E90 3 Series were better all round.

But 17" Pirelli run-flats on my E91 and 4 sets of 17" Pirelli run-flats on my E87 1 Series were the best run-flats I've had.

Although the 18" Kumho Ecsta non-runflats on my MC are better than any of them so if non-runflats are an option that may be the way to go!

But in terms of brand everyone has their own preference.
