So you're trying to stick with >140 treadwear street tires on the stock wheels for the street tire index? I agree, not many good choices.

RS-3 275/ 305, though the larger front diameter may confuse the ABS sensor.
RS-3 235/ 305, better diameters, too much understeer?
ZII- 245/ 275, diameter issue again, and less footprint than you'd like.
AD08- 255/ 295, good diameters, but older/ slower compound than is ideal.

I haven't run the wrong diameters on the 1M, don't know how bad that would be, but if it kicks the ABS into "ice mode" more often it could be a real problem.

I think you're kinda screwed... I understand more Rival sizes are coming, maybe run the AD08s until they get here?
