Basically is 5 years, Michelin, I read somewhere they mention 6 years, but also got to see where. Hot climate like ours I doubt can go 6 years unless like you keep wira locked up in garage.....lolP
Normally regardless of what tyres, 5 years is usually the limit isn't it? Best not to push it longer than that as the rubber compound will harden.
Well, they removed the cracked putty away and I saw the bare metal area inside where it was grinded and welded before previously. No rust at all. Likely putty issue in this case.
My Goodyear Asy2 from EU, about 5 years, my GT Radial from Indonesia I would say 4 years they start to crack.
