So that means that if the supposedly uniform new rules (NCOPS ?) are strictly applied and 235/85's are taken as approximately somewhere in the 800-810mm overall diameter range new (approx. 31.5-31.7") the tallest tyre you can legally fit is something like a 255/85 at 846mm/33.3" tall or the 285/75 at around the same height.
Has anyone tested that yet ?
