I have put the 18” wheels from TSportline on my 3 performance; with the EPrimacy the rim is recessed by about 5mm from the tyre.Good Question, I was looking on the photos but could not find any M3 R18 with E.Primacy fitted. From photos they looks very similar to PS4 T0 when it comes to rim protection.
Now, I thought it was due to the shape of the wheel and not the tyre itself.
It isn’t flushed like it was with the PS4 and the Tesla wheels
