The difference between 275/40 and 295/40 equals out to 18 full rotations per mile!!! I have personally seen and had to fix the problems created by this, namely... transfer case. In 2000 - 2003 X5s it usually strips the splines at the front output shaft of the case costing you a front driveshaft and a transfer case. In 2004 - 2006 X5s it causes substantial wear to the clutches in the case where it transfers torque split to the front wheels, causing once again the transfer case to need replacement.
It would be like having different gear ratios front and rear of your 4 wheel drive... you just don't do that.
