BMW recently switched from PS2 to ContiSportContact 3 as OE tires for the M3. But load rating is the same - 93Y/98Y.
Do "find OE tires" after you select your model year and this is what you get:
2011 E92 M3 DCT
1991 Spec Miata
2008 E92 M3 DCT - KW Competition 2-way / Brembo 365 BBK / OMP ARS racing seats / rear seats delete / GT4 aero / AiM EVO4 data logger / SmartyCam racing camera
2008 E92 M3 6MT
2008 E92 335xi
