It rode fine but when I deflated the tires later to the recommended pressure I noticed the tires produced a bit more noise.

Wanted to hear other X3 owner's experience with their PSI

Thanks!
I just picked up my new X35 at the factory (great experience) and checked the tire pressures the next day. Same Pirelli P7 tires as on your vehicle. Found them to be higher than the 32 F, 35 R recommended in the manual for speeds under 100 mph so I reset them to those pressures. Found the handling was not as good, so I contacted my service advisor and he recommended I inflate them to the over 100 mph pressures, 38 F and 44 R. I did that and handling has improved, but I can now feel the imperfections in the road more, unless I am on a smooth surface.
