Confusing tire pressure advice on 2024 Performance Z

[bpeckham]

Your search string seems to have shown the results for the Sport, citing Michelin and Toyo. Anyone with a Sport care to share a photo of the door jamb sticker?

If you use the tire pressure monitor when putting air in the tires the horn honks (vehicle must have the engine running) to indicate that you have reached the correct pressure. I have checked all my Nissans and the pressure indicated is 38psi. Hmmmm???

Set the tires cold to what the doorjamb sticker says.

From the internet :

Optimal Tire Pressures
General Guidelines

• Standard Road Tires: Follow manufacturer recommendations or adjust to 40-45 psi if experiencing excessive edge wear.
• Track Day Tires: Use manufacturer-recommended hot pressures. For example:
  • Yokohama A050: 29-31 psi hot
  • Toyo R888: 28-40 psi hot

Pressure Adjustments Based on Vehicle Weight

Vehicle Weight	Cold Pressure	Hot Pressure
Very Light (<800kg)	17-22 psi	22-29 psi
Light (800-1400kg)	22-27 psi	30-35 psi
Heavy (>1400kg)	27-35 psi	37-40 psi

I guess I know better, running 34 f / 32 r cold and I like how it rides better.

So it looks like Google got it wrong for the Sport, suggesting 35, but the actual is 33. Only the NISMO gets 35 and only for the rear tires.

Any members care to share their door jamb stickers? @yellowz6mt already shared their Performance sticker. @50thZ, you have a Sport, right? Care to share your sticker? Any NISMO owner out there care to share?

We can see if they match the data from the owner's manual.

Assuming the OP was asking about their Performance model, it seems like the only correct answer can be 32 front and 29 rear.

Giving the answer for a Sport to somebody asking about Performance seems like bad advice.

If your preference is to run something other than recommended, that also seems like the wrong answer for somebody who's confused about what the right answer is. The right answer is from the door jamb sticker or the owners manual. Hopefully they at least agree with each other.

If OP had asked "I feel like running at different than the recommended pressures, what should I run?" Well then, one might expect this thread to go every which direction.

Quoting "the Internet" or "Google" or "ChatGPT", as demonstrated by this thread, isn't a great idea as it resulted in mostly wrong answers. Don't believe everything you read on the Internet. In fact, don't believe me. I'm just some idiot on the Internet. Go out to your car, pull out the manual, read the door jamb.

I would follow the posted tire pressure on the door Jam cold 29/32 psi for performance trim. ChatGPT is limited as of now.

This.

A.I. is nice for some things but nothing beats what the mfg prints on a sticker.

It's literally on the current tire pressure screen on the dash, they even used blue numbers to tell you it's cold pressure. For the performance it is 32 front 29 rear COLD.

Stock wheels and stock tires? Use the sticker cold pressure, 32 front and 29 rear. Pressure will change based upon ambient temperature and driving.

Here's another example of robots answering questions. I used this when I changed my wheels and tires trying to figure out cold pressure:
Here's a quick summary of how to determine the correct tire pressure when changing wheel and tire sizes.
The process isn't a simple mathematical formula like A+B=C. Instead, it's a load-matching calculation based on official industry standards. The core principle is to find the new pressure that allows your new tires to carry the same weight as the original tires did at the factory-recommended pressure.
The 3-Step "Formula"
* Find the Original Load: Look at the tire inflation placard on your vehicle's door jamb. Find the recommended pressure for your original tires. Then, use a Tire Load/Inflation Table (available online) to find the exact load capacity in pounds (lbs) that your original tires could carry at that specific pressure. This is your target load value.
* Identify the New Tire's Specs: Find the Load Index on the sidewall of your new tires. This number represents its maximum load-carrying potential.
* Match the Load: Using the same Load/Inflation Table, find your new tire's size and load index. Look across the pressure settings until you find the psi that meets or slightly exceeds your target load value from Step 1. That is your new recommended cold tire pressure.
In short, the "formula" is: Original Tire Load Capacity @ Factory PSI = New Tire Load Capacity @ New PSI. You are solving for the "New PSI".
