However, depending on if you got the sport package, the tires may be rated for 45PSI for normal driving (tread ware). Most vehicle manuals will say 35PSI to be on the safe side (as most tires are rated at 35PSI), but newer tires these days are rated much higher for daily use. For track days, it's good to air them down to about 30PSI. They're perfectly safe (and definitely going to have more life) at 45PSI if you're not tracking the car.

sports package tires here and the tires clearly say DO NOT EXCEDE 40 PSI. i hate to say it but i am going to listen to it.

front tires 37.5, rear 38 and 39. There all set to 35.5 now, it gets cold here lately so tonight they will be at 35, will put them at 35 even in summer time.

Just a quick question to those who had high tire pressure...were your tire pressure sensors going off?

It is always a good idea to check tire pressures immediately after taking delivery of a new car. I buy cars rather frequently and have learned not to trust the dealers and in most cases find the tires to be underinflated even on the high end vehicles like Mercedes. This 370Z is the first auto where I found them all to be overinflated.

As you can see, the tire pressures are tire (19" Sports Package Tires) specific meaning Nissan didn't just put a generic tire pressure for all the Z trims. So, I changed all 4 tires pressure to 35 PSI.

In my case no sensors were going off, no warnings, etc. I was just checking the pressure on my daughter's car and I checked my Z. Wow... 45 psi is high!

Sounds like several had high pressure and several did not. I will check next time I take delivery of a new car.

Just checked it and it was 41psi all around. Would there be any notable damages to my tire if I drove it around at this psi for over 2 months?

no not at all. if it was super over inflated then u will see uneven wear in the tire, plus run the risk of blowing out.

Actually, overpressure tends to not blow a tire - it runs cooler...

Underpressure heats them up more, weakening the tire, eventually causing a failure.

At least, that's the motorcycle knowledge speaking.

My bike recommends 35psi. I run 40. Tires wear longer...in my case.
