The e46 m3 csl (the only S54 car that runs 235 & 265 widths) uses 235/35 & 265/30 19" from the factory. The 18" option for an e46M3 is the same as our cars 225/45 & 255/40.
If I was running 19s and wanted to increase width I would go with BMW's choice above. If I didn't want to increase the width I would go with the 19" spec for a normal e46 m3 which is 225/40 & 255/35. Worth noting though that a standard 19" m3 wheel is an 8j and the CSL wheel is 8.5j.
