Should I replace tyres that show signs of cracking on the tread?

I bought a 2017 plate BMW Series two years ago. When I bought it, it had 80,000 miles on the clock. After two years of ownership, it now has 86,000 miles on it. The tyres are all Bridgestone and were on when I bought the car. They are all legal regarding tread depth and they passed the MoT in July without any advisories. I have noticed that at least three of the tyres have slight cracking towards the outer edge of the tread. Is it okay to continue using them as they are road legal, or is it an issue that needs addressing?

Cracking typically indicates that a tyre is ageing, or can occur through prolonged exposure to UV from sunlight and extremes of temperature. It represents a significant safety risk as it could result in a blowout, and you should have them replaced as soon as possible.
