Boring question: winter tire pressures
Just mounted my snows and am unsure of the optimal tire pressures for an E90 335i with ZSP. I'm running square set of 18" 193M reps with 225/40/18 Michelin Pilot Alpin PA3s.
I typically run 36 F / 39 R in the summer on 245/35/19 F and 275/30/19 Bridgestone RE11s but given the square setup I have no idea what the right pressure is on the winter set. I'm in the GTA so I don't expect to actually ever see any snow, just cold dry pavement.
Thanks in advance,
