I was just wondering why the tire pressure that nissan recommends for the 370 is so high? I had a C5 Vett, and have looked at the C6 as well, and the tires were....are of about the same size and profile, and the car weighs about the same as well, and the recommended pressure is 30 all around......although Vetts come with runflats, but I changed mine to non runflats and the 30lbs felt fine! I mean, the pressure should be decided by the size tire and wheel, and the weight of the vehicle, front and rear. If vehicles are basically the same weight and have the same size tires and wheels, the pressure should be about the same or very close, no?
I put 35 in my new tires and it feels way to much pressure for me. Was using 34 in the OEM's. Going down to 33 to check it out.
