Tire Pressure: Nissan or Tire Spec?

Maybe I dont know much about tire pressures, but isnt 32 to 44 psi a big difference? IMO, if the heavier the car, the more air I would put in the tires(sound right?). Lastly, it would matter more on the type of tire you are using(17-18's)...

Yeah, my Michelin Pilot Sport A/S's claim a maximum pressure of 51psi, Nissan recommends 32... I use 35-38 and the car rides great. The car feels a little "squirmish" in its handling sometimes at <32psi.
Note that I'm also using 235/45-17 on 17x7 wheels, where the wheel width (7") is supposed to be just a little too narrow for these tires...

44psi is maximum COLD pressure...NEVER use that!
I used to run 40-41psi and it was HARSH. I felt every little pebble, crack, hell even ant I ran over.
Then a couple tire gurus on here showed me the extreme science/testing behind those pressures and how running out of spec is DANGEROUS, so I run within 2-3psi of Nissans' recommended 32psi. It made a dramatic difference in ride quality and handling, however tire wear increased somewhat.
Once you vary from OEM brand/size tires, I'd do some research on the "best" pressures to run.

I second Alex's suggestions. I run 34 psi front and 31 in the rear; no need to run same tire pressure on rear if 63% of the weight is carried by the front wheels, eh?
Try some moderate differential pressure...you'll like it

I run 35 F/ 32 R

should never inflate to the max labeled psi. says MAX for a reason, not maxima har har... I think i read 32 was ideal all around but since they say you lose on average 1 psi/month, i just do 35 and be lazy..
