Ah thanks for clearing that up. Any advantages/disadvantages to either setup?
Debating if i should try out the M5 tire size on my 19" M351 (8.5" all around). Oem spec calls for 245 40 19" tire while the M5 front wheel is 19x9 which calls for 255 40 19" tire. I like the fact of having more sidewall for winter roads and i don't think it would cause any issues with the bigger diameter since the front and back will be the same. Another member here is rolling on 7 series size wheels/tires on his F10 without issues. I am just worried that the tire will look really square/chunky on a 8.5" wheel.
