Did the manufacturer consider the tropical climate and heat in Thailand? I've had my michelins on my crv for close to 4 years and 50K kms. They have surface fine cracks on the outer edge of each tire. They may be good for another 10-20K kms, probably no more. But 10 years? I don't think they'd last that long as the rubber hardens over time and dry grip reduces. I'd rather follow my observations of the tire quality and performance (braking, noise), rather than what is stated on the box. I've also replaced some tires as 40K kms when it was obvious they were becoming noisy and hard.
