Does anyone know why the 135i all-season tire option differs between Europe and the USA (205/50 17 on 7" wide wheels all round USA; 205/50 17 on 7" wheels front, 225/45 17 on 7.5" wheels rear Europe)? Also, what all-season tires are provided in Europe. The Goodyear LS-2's provided in the USA are only so-so.
I have also posted the same questions on other BMW sites and have not been able to get a response. Why is this information so hard to get?
