I just picked up a new to me Black Sapphire Metallic 2015 650 GC. I put the M5 wheels and tires (that I had pulled off my 550) and it changes the look completely, I've got a pair of M6 grills coming. Later I'm going to change out the mufflers and ditch the trapezoidal exhaust outlets to M6 mufflers with the M6 rear diffuser, then lower it just a taste, probably with ACS springs as I want to preserve the ride quality and don't want to feel every irregularity in the road.

But getting back to my original query, on my 550 I was running 36psi all the way around. Looking at the tire card on the GC it calls for 42 in the front and 39 in the rears, but that's for the 245/275 20" set-up, I'm running 255/35's in front and 285/30's in back on the 343 wheels. Right now I've got 38psi all the way around. You guys with M5 wheels, what are you running tire pressure-wise?
