Hello fellow X1 drivers;

I'm here to find out, who has different tire size than the factory one, or for those that have wider tires.

Well My X1 came with:
(Pirelli P Zero Run Flat)[220 AA A]
225/40R19 in the front {26.1" overall diameter}
255/35R19 in the rear {26" overall diameter}

I want to put wider tires on those (8" front and 9" rear wheels) but so far, I am interested in:
(Bridgestone Turanza ER 300 RFT)[320 A A]
245/40R19 in the front {26.7" overall diameter}
275/35R19 in the rear {26.5" overall diameter}

So I was told by a tire expert that the "overall diameter" is a factor and in this case. That the difference between from and rear height can't be much (in this case is (0.2 on the possible new ones). Now

Now being that they are wider (20mm added), I wonder if someone has 245 in the front and 275 in the back? Please share specs and pictures if possible.

Also, if someone has 20" wheels please share specs and pictures if possible
