According to BMW CANADA the following, is the actual dimensions of the 19" alloy wheels and they do not recommend a aspect ratio higher than 45 for the 19" wheel. BMW CANADA will probably not support a higher aspect ratio than the original 18" tires on your vehicle.
The dimensions of the 19 inch double spoke alloy wheels are as follows: 8,5Jx19 EH2+ with an offset of 38mm. We do not recommend any tires with an aspect ratio higher than 45 for the 19inch wheel base. This is a result of extensive testing by BMW AG. Any non approved changes to the tire or wheel package would make the vehicle unpredictable and could cause issues with the suspension/steering.
Do you really believe BMW CANADA on this issue?
