Just to add a tiny bit to the anal uber alles vibe, IIRC in Germany just replacing the illegal pair (optimally putting the new tyres on the rear) wont do, you are compelled to replace all four tyres as a set.

Logically that should imply there is some standard for relative tread level difference between axles in service, though I dont know if that is the case, and it would be complicated to administer.

All OK by me, though since it contributes to the UK supply of cheap part-worns. though I probably wont again have a car in the UK.

We will indeed be in France as well, but we''re used to driving in France so have the stuff. This year however the greater Nancy area has from 1 Jan 25 a low emissions zone, so I have had to apply for a Crit Air sticker otherwise we wouldn't be allowed to enter. No pay x amount to flout the rules there. Fortunately the requirement for a passenget diesel car is only Euro 3. My car is Euro 5 so no issues, but you must have the sticker.

After a bit of reading, it seems the new Italian rule is not that draconian - what are banned are winter tyres in summer with a speed rating less than that required for the car. A set of all seasons would therefore probably not be affected.

Thanks for the update - it is true that winter tyre speed ratings can be lower that the car's design speed but summer and all-season tyres can't.
