thoughts on tire pressure?

redline2 · 10-27-2013, 10:36 PM

I just made the plunge to regular (non run flat) snow tires. Running the Yokohama IG52C with 34psi in front and 39psi in back on a 335i coupe. Any thoughts or recommendations on pressure for this tire size? Door sticker is for the OEM 18" so I'm going by the car manual for the 225/45/17 size (<160kph) but the fronts look incredibly flat and slightly bulging. Doesn't look right!

My SA suggested 36 psi all four. Sport package setup.

I always go with 33 front and 41 rear. Though I do usually bump up the fronts to about 35 instead.
