Toyo & Michelin warranty period = 6 years
Other brand = 5 years
So any tyre after the period not able to made warranty claim, but doesn't mean the tyre cannot use.
It depend on tyre condition, imagine why some car their tyre still have so many RTD(remain tread depth) after 5 year, because they selfdom use on the road. That the main reason why tyre rubber crack on tread/sidewall.
So after 5 years and tyre got crack lines you will still use?:hmmmm:





No wonder some people can use tyre until 10 years also don't change
