Hey all I have a 2019 m240i on stock suspension with oem wheels/tires and will need to change tires soon. Would 245/35 18 square set up work on my oem wheels. My current is 225/40 front and 245/40 rear atm.

This is an excellent fitment guide, which should answer your question. At least as far as Apex wheels are concerned.

What you'll see in the middle of the image below is that the minimum rim width for a 245/35-18 tire is 8". If your front wheels are 7.5" in width, the tire industry considers them a bit undersized for that size of tire.
