Sorry. I'm only running 18" on track (which, presumably, is not an option in street tire class).

For the record: the 1M MotoGP Safety Car featured a 255/35R19 (front) + 285/30R19 (rear) setup (fitted on the E92 M3 GTS wheels), though with a modified suspension system.

"In the interests of weight optimisation, the BMW Safety Car comes with a carbon fibre-reinforced bonnet featuring additional large air vents, as well as polycarbonate side and rear windows. A special lightweight titanium race exhaust system not only saves weight but also delivers a captivating sound for the benefit of the spectators. Complementing the discreet spoiler lip on the boot lid there is now an adjustable rear wing to provide the requisite downforce. On the Safety Car the aerodynamically honed front apron with its precisely defined air ducting, including Air Curtains, features an additional splitter integrated on the underside of the apron.
The interior of the BMW Safety Car is a model of uncompromising purism. A rollover cage bolted behind the B-pillar, the absence of rear seats, two racing bucket seats with 6-point safety belts, an M steering wheel in alcantara and a fire extinguisher are all standard in the Safety Car.
The suspension technology of the BMW 1 Series M Coupe was specially adapted for the Safety Car. Its high-performance suspension system boasts an adjustable race track set-up that includes a sports-tuned chassis in which the dampers are independently adjustable for bump and rebound. The BMW Safety Car runs on 19-inch mixed tyres measuring 255/35 at the front and 285/30 at the rear. Vehicle height is variably selectable and the camber of the front and rear axle can be altered to suit the circuit topography. The braking system of the BMW 1 Series M Coupe, already designed for extremely high demands, is replaced in the Safety Car with a six-piston fixed-calliper racing brake system."

I see that the Safety Car runs Pirelli PZero Corsa tyres. Anyone got experience with them? Namely comparing to Michelin PSS? Thanks
