What tire size do I go on 18x9.5 et38

I have a 07 335xi sedan I was wondering what is the max tire size I can fit on those rims without rub. I got 10mm spacers for the front only.

245/40/18 for the front. And 275/35/18 rear. Others may say 235 front and 265 rear.

Don't do that. You'll have issues with xDrive with the different diameters. Do 245 or 255 square.

Yea. Some come with staggered tire sizes. You need to keep size difference under 3% I believe. You’ll want to search.
