[135i_Mevoila]

I am looking at getting either 18's or 19's on my white 135i.

I am looking at the TSW Nurburgring Gunmetal Matte (Graphite)
The 18's have the following specs: Size: Front 18x8.5, Rear 18x9.5; Tires: 225/40/18, 255/35/18
The 19's have the following specs: Size: Front 19x8.5, Rear 19x9.5; Tires: 235/35/19, 265/30/19

I am concerned that the 19's might be too big..Would I have to make any adjustments?Also having 8.5 in the front and 9.5 in the rear, would the wheels/tires stick out or would they still be flush with the car?

thanks for any insight.
