Other than visible tyre damage like sidewall punctures and metal/nylon plies exposed to ambient, according to tyre manufacturers across the world ONLY 10 year tyre age AND tyre wear touching ' tyre wear indicator of standard 1.6 mm height' are (mainly) the criteria of discontinuing service of said tyres.
Other incidences like loud tyre noise/hardened rubber compound/so-called slippery/so-called handling/tyre botak/so-called scratches and roughened patches/rubber compound surface cracks etc etc does not fall under the criteria of tyre manufacturer requiring service termination/replacement of tyres.
My tires was >8 years old (due to long storage on rim, but off the car), when finally install on the car, had loud tire noise and can feel hardened rubber.Other incidences like loud tyre noise/hardened rubber compound/so-called slippery/so-called handling/tyre botak/so-called scratches and roughened patches/rubber compound surface cracks etc etc does not fall under the criteria of tyre manufacturer requiring service termination/replacement of tyres.
Of course tire shops wanna make $$$, keep asking to change, but just kept using it.
But it did exhibit accelerated wear and was worn out within 3k-4k km.... worn so fast until inner nylon/fibres visible.
