Fronts: 8.5x19 wheels and 245x35R19 tires
Rears: 9.5x19 wheel and 275x30R19 tires
Not certain of the OEM stock sport wheel offsets?

I just picked up some BC Forged wheels with the following specs:
Fronts: 9x19, +15 offset
Rears: 10x19, +25 offset

Now, my question is: Must I get the same exact size tires or can I possibly fit a larger tire without any rubbing to give it a slightly more aggressive look like an M5?

Please let me know your experience, advise, suggestions and/or opinions. Thanks!!
The 550i sport stock wheels are 18 Front and 32 Rear offsets
so you basically adding half inch of width that will be distributed to 3mm to the inside and 9mm to the outside in the front.

In the rear, you are putting most of the extra half and inch to the outside (about 14mm).

I think you'll be OK, the easiest to try is to put masking tape across the fender well and see how much clearance you have between the wheels to the masking tape on the stock wheels. The question is are you dropping/slamm the car with aftermarket suspension?
