For my E53 summer Michelin Latitude Sport 3, 19”; winter Nokian Weatherproof SUV (which are actually all-season tyres) 17”.
For the F15 summer Continental Sport Contact 5, 19”; winter Pirelli Scorpion Winter, 18”.
I need to replace the F15 summers and will stick to the Contis.
If I were to change to none run flat (insurance currently forbids) I’d definitely go to Latitude Sport 3 - in my experience it’s a really good tyre.
As TriX5 says, it’s a very personal choice.
