Should I replace my tyres on my car after seven years?

I have a 2015 Honda CR-V, which has done almost 36,000 miles. It still has the original tyres which were manufactured in Dec 2014. The car was sold in January 2015, so the tyres have been in use for about 7.5 years. They all have between 3.5mm - 4mm tread left. I have heard that you should replace tyres when they are this old. Is this correct or just an old tale? What would you advise?

There is no actual age limit for car tyres but they are made from organic material and (like all things organic) have a limited lifespan.

Most manufacturers recommend tyres at 10 years, regardless of condition or tread. This is because the rubber polymers weaken over time and the chemicals dry out, which makes the tyre hard and liable to cracking.

The tyres are inspected as part of the annual MoT and service, which will give you a good idea of their condition. If these reports are fine then you may have a year to two of life left in your car's tyres. But I would suggest that you keep an eye on their condition and inspect them regularly for signs of damage.
