Until recently, I was unable to find the proper paint to refinish curb rashed wheels on on my M235i. However, I found a source: paintscratch.com, that sells the correct paint. On their site, it is listed as a 2017 M2 color- B35. I purchased a spray can ($26.95) and a can of clear coat ($19.95) that were sufficient to refinish all four wheels. The also sell more complete refinishing kits. Caveat Emptor: the prep must be flawless before painting. One great trick I found on a DIY site: buy a deck of Bicycle playing cards to insert between the tire and wheel to mask the tire from the wheel.
