Just to let you know, this is not a safe combination for xDrive vehicles and can damage your transfer cases. BMW says not to deviate more than 1% in diameter between axles/tires, the 35's are 3.4% smaller in diameter.
Are the tire sizes you listed accurate?
EDIT: Saw the post above, 255/35 is the OE spec and only .4% smaller in diameter than the 225/40. Perfectly safe.

& no worries, xDrive is nit picky & these are expensive cars, it's always best to take your time & ask any questions you have so you don't mess up & regret it all later!
cheers!
