Hello,
I'm now running 295/25/22. Now I'm thinking 295/30/22 or 305/30/22 on the rear.

I run 295/35-21 on the back and 275/35/21 on the front of my B7
the 295/35/21 on the 10.5 " rim has a foot print of 11.6 "

295/35-20 rear and 265/40-20 on the front of my 2006 760Li in the summer with Michelin Pilot Sport PS4 S.
Because I like the PS4 S and because the extra 20mm, over the more commonly seen 275 and 245, gives better rim protection to the snowflakes, which are pretty but flat faced.
Winter 265/40-20 front and rear now with Michelin Pilot Alpin PA4 - yet to see any action.
The only issue is that even the 265/40 front won't go in the spare wheel well.
Weird thing is 255/40 PS4 S on 8.5J M167 and 275/35 PS4 S on 9.5J M167 give much better rim protection than said PS4 S on snowflake 9J and 10J
Footnote: PS4 S are available as aftermarket (optimised to look good in official economy, wet and noise tests, though be excellent all-round) and more recently as manufacturer approved.
AO Audi - Not seen these yet
MO Mercedes - not visibly different from aftermarket. Data says something is different, but not noticeable under normal driving.
Ferrari - WHOA big size difference - 295 more like 315 on those I've seen. Lots of these s/h - caution!
There were some early tyres with different tread pattern - Not seen these in the solid.
