I'm planning to order a 128i soon, likely with the Lifestyle Edition package (ZED).

I was surprised to see that the ZED package comes with 18x8 front / 18x9 rear wheels because the M-Sport package comes with 17x7 Front / 17x17.5 Rear wheels (128i M-Sport) and 18x7.5 front / 18x8.5 rear wheels (135i M-Sport). The ZED package rims are pretty wide for a factory option, especially on a 128i.

I was hoping to somehow go square with 225/40-18, but I don't think that's likely with 18x8 front / 18x9 rear wheels. Is it possible, or even advisable to go with 235/40-18 all around on 18x8 and 18x9 wheels? Or maybe 245/35-18 (same diameter as stock) or is that too much front tire for a 128i?

I know aftermarket wheels would solve everything, but I like the Style 496 wheels that come with the ZED package, so I'm curious about my options if I want to stick with them and go square.

Thanks in advance!
