Any help would be greatly appreciated.
Although we technically call this 'plus zero' (plus one goes up one wheel diameter size to 19") you have the right idea. For wider tires on the stock M3 18" wheels you can use 245/40R18 up front and 275/35R18 on the rear. 255/35R18 is pretty short in height for the M3 and not recommended.
