"In the standard version, the cast 18" 'M' double spoke wheel (style 260) is available for the E92 M3, with the forged and polished 19" 'M' double-spoke wheel (style 220) available as an option. These are weight-optimized M3
light alloy wheels.
The tyres are also specifically selected for the M3. The Michelin Pilot Sport (PS2*) is currently fitted."

So, yes, it is likely they weigh about the same, with the forged probably being stronger.
