Just read in manufacturer's website. Why rely on third party information?

I have a KIA Rio that came with Continental CSC5. Made in 2014, still using today. Forget about those bullshit about 5 years old tyres. Yes, I used to believe this shit too. However Continental state in their website that their tyres would stand up to 10 years. Going to try and use it for as long as I could and see if their claim is true.
