15k miles on 7+ year old tires - replace or ok for now?

I'm purchasing a 2011 328i coupe that has ~15k miles on it. It literally looks brand new inside and out, not a speck of surface rust anywhere. The tires are original, although there's no signs of dry rotting or anything, and there's still a lot of tread left. The PO purchased it mid 2010, so they've been on the car for over 7 years now. I've read that some manufacturers say tires are good up to 10 years provided you get yearly inspections after the fifth year, but I'm not sure if run-flats are any different. Any insight would be greatly appreciated.

Also, I am planning on eventually ditching the run flats, but I feel like it's a waste to get rid of them immediately considering the tires at least look nearly brand new despite their age.

You'll be fine.

Personally I would drive on them, especially considering that they are run flats.

7 years is fine. 10 years is when it gets iffy.

The 10 years figure is probably taking into account proper storage of the tires while they were on the car. Even parking the car outside in cold temps for the winters will reduce the life of the tires.

If you're buying from a private party, maybe ask them to knock a few hundred off? I would replace the tires ASAP, 7 years is a while especially if you can't account for where the car was for those 7 years. Why risk it?

Michelin and conti directly say 10 year use and hotter climates are worse so being in the north actually helps.

Inspect the tires...if they don't look chewed up, drive on them until their visual condition warrants otherwise.

The only time I've ever been worried about driving on old tires was ~4 years ago. A friend of the family had just bought an '82 911 and threw me the keys to take it for a spin. Before taking off, he told me it was completely original, down to the tires....I threw the keys right back and said "no thanks" lol

If there is no dry rot you should be fine.

I'd consider getting new. The depth of tread may be good; but the compound can age, affecting the stickiness of the tire. This is more pronounced on higher performance tires.
