[quote=Diego Mamani][quote=flu]I was looking up the DOT manufacturing number, and it ends up the ones I got were made back in 2010… Great. So I contact tirerack, who basically told me that the tires were stored properly in their warehouse, rotated, correctly, and that all the other kumho tires they had of the exact same type were made roughly with the same date. They offered to give me a $40 credit total. I am a little annoyed, because tires have a shelf life, but then I already had them mounted and didn’t want to go through the hassle again…and realistically I go through tires in about 2 years anyway…[/quote]
Back in Nov ’06 I also bought Kumho tires from tirerack.com for my ’01 ‘Stang. But they were new tires, made earlier that same year. I’m glad you brought up the issue of tires’ age (in years). There’s agreement that tires can go bad just from the passing of time, even if miles are low. But no one knows how old is too old. Some people say 6 years, others say 10, still others say don’t worry if you keep your car garaged and your weather isn’t extreme. I don’t drive my Mustang much, so the Kumho tires only have 20K miles, but almost six years… I’ll probably change them by year end, just to be safe.[/quote]

6 years is about what I tell people with a low mileage car. Just to be safe. I never make it past 3 for it to matter.
