You know, since it's reopened and all...
Basically do your homework on your particular tire design series. It varies IMO based upon that.
My trucks run Michelin LTX series. My M/S2 will be replaced by defenders it appears when time comes- size restrictions, also happens to be whats on the gbodies in a 205/70/14. Never wear a set out before getting old and everything is great. Best rain and snow tires overall without going extreme one end of spectrum or another. I used to be a Cooper discoverer fan but these are much better.
My clk benz has always run on Pilot Sport series tires while I had it... They've always been great. Again, age gets them before mileage, even though they're a lower life rated performance tire (compararively).
My '14 mustangs ride on factory pirelli p zero neros, an intended summer only tire. I've noticed grip fades with age before lifespan wears out. Rated a 30k tire, one car is at 21k and has 3/4 treadlife left as an example. Not dried or rock hard/cracking, but, much easier to get squirrely when your 4-5 years in than new. I've got another set of these as new takeoffs on the rims to go on, but, I definitely wouldn't pay sticker for them, they're serviceable but not worth the price IMO due to fade and low mileage rating.
Wife's 2016 mustang came with the Hankook. Ventus noble s2 series. They're "ok". I can definitely tell the speed of the car based on noise and vibration. Up above 70 mph and you start to really notice it, and increases as speed does. Below that, not so much, more likely every other basic tire. I rate it as a does its job tire, OK rain but again, not great. I've gotten as much as 102k miles on one tire from the original set, the others suffered punctures (nails/screws) outside the pluggable surface in the 60-90k mile range. It's rated for much less life, but these were driven lots when relatively new. Can't speak to aging and how that would affect it. We got additional as "new take off" wheel/tire/lug combos complete down to TPMS. Hard to argue with $400 complete off a new car.
