I’ve still got the original tires on my ‘92 Miata that I purchased new way back in the Spring of 92. They do show a bit of weather checking, but thus far haven’t failed.
They’ve got about 32K miles on them now, just getting broken in!
Probably should shop for something that will last me until maybe 2025 - then I’ll convert to one of those Mr. Fusion powered devices!!!
Exactly, old tires driven by granny to the market on Sunday is a lot different than tires driven buy the guy who just bought granny’s car and then commutes to Detroit every day to work.
A lot of this depends on proper air and climate also. tires in Fl see a lot more sun than tires in Mi, so the sidewalls by age could be completely different with the same miles and use.
