My current car was new in 2020 and came fitted with Bridgestone Potenzas. At four years old three were suffering from tread cuts and sidewall perishing and cracking, and since my car doesn't have a spare wheel, I opted to change them. To my surprise, when I looked up replacement tyre availability, the Potenzas were listed as "suitable for summer use only" in Britain - I hadn't been warned of that by the dealer supplying the car. They've now been changed for Goodyear all-season tyres, since I don't have space or facilities to keep separate summer and winter sets (in common with about 99% of UK car owners I suspect).
Almost nobody has winter tyres in the UK. 99% of cars have summer tyres. They're just not necessary because there is about a week a year when road conditions and temperatures are such that they might be helpful.
All-season tyres are likely to be a compromise at both - they'll wear faster than summer tyres. (The difference is how hard the rubber is)
