So you're more knowledgeable than tyre manufacturers and their Associations from Europe, Japan, UK ?
Btw, I'd previously replaced two Michelin XM2 tyres after 115,000 km usage at 6.5 years post manufacturing date.
Currently running another pair of XM2 with 55,000 km usage with 4 years post manufacturing date.
Are you more competent than Michelin in advising a user like me to condemn the current pair of XM2 tyres, according to your '4 year' myth/blufff ?
after years of playing with cars, learning cars, working car, modifying cars
i learn not to believe everything that car manufacturer tells u, they're there to earn money from u
give u some example...never believe a car manufacturer telling u to pump 250kpa into a perodua axia, it's at the side plate, u can check
it's basically over inflating the tyre
also never believe authorized service center tell u u need engine flush or radiator flush or transmission flush
those thing basically destroy the part that it flush
now, since u told me me your tyre has been driven so long
when you're driving faster and faster, did u hear a noise that is getting louder and louder as u go faster?...the sound is very rough
if u drive cheap car like a saga/axia(no soundproof), u barely even hear the radio...u need to turn up your volume
u realize it's not as quiet as when the tyre is brand new anymore
that is your tyre rubber harden already...and due for replacement
if u go inspect your tyre, you'll see alot of wrinkle/crack..that is another sign of your tyre rubber harden already
