I personally would follow the 6 year recommendation for more rigorous inspections of the tires and aim to replace the tires within a year or two (waiting for a good deal, for example).
On the other hand, if one believes rubber does not deteriorate with time, I wish them the best with their BMW coolant hoses.

You didn't mention how frequently you replace your BMW (if that really matters) coolant hoses just because you believe. I believe
tyres are made of a lot sturdier rubber than hoses and yes, I do care to warm up my engine carefully (to prevent any extreme temperature burden on that rubber) as I know cooling is my BMW engine's weak point, in particular (many complained).
So far (almost 12 years) so good. No leaks.
And I am not a fan of wheelspin, drifting/sliding or hard braking either.
