18" staggered 255/35 R18 all season tyres

[SoupAnxiety]

Has anybody found an all season tyre in 255/35 18"? Googling finds 19" all seasons but for some reason 18" is unloved. My summer wheels for the E92 daily car need new tyres soon and it would be nice to be able to go down to one set of wheels. Thanks!

Seems as though you're having the same trouble as I did on my E91 with 225/40/R18 fronts and 255/35/R18 rears.
A few manufacturers do the fronts but frustratingly, not the rears.
I wrote to Michelin about their Cross Climates last year, and they replied saying that they had no plans to do the rear sizes either.

Thanks for the heads up about your letter and the response. It's frustrating that the 255/35 R18 size isn't available, I understand that all season tyres are a compromise but for the journeys I make an all season tyre would be more than enough. Swapping wheels over in the rain in October will continue!
