Hi, I'm in process of switching out the OEM 19" staggered summer wheels/tires on my 2019 430i x-drive Gran Coupe to 18" square setup.
Decided to go with Enkei Raijin 18x8.5 et38 wheels (ordered today). Likely putting 225/45R18 rubber on them, something all season, likely from Costco or Belle Tire. Open to suggestions.
The wheels:

From my perspective a relatively classic look, good quality product at a reasonable price. And they fit. That helps a lot.
