What tire pressure do you run on your daily Z?

madmike23

Yes, they do. But I would recommend the pumps you step on. Easier to pump.

On 35 I've noticed around some corners i get a little slidey I've always ran a few PSI higher just in-case for this issue.. Its so far helped so 37-38 for myself

Automatic cool points to the first one to install Presta valves on a 370z.

I run 40 psi and no wear issues so far on my 14 nismo at 6k miles. Actually, my tire pressure light on the dash went on the other week and when I checked all my tires they were all at like 33psi. Not sure what the trigger is set to for the light to come on but it did... thought I had 1 tire that was lower pressure then the others but that wasn't the case.

For those that don't know...Tire pressures should be taken/filled when the tire is cold.

is your pressure gauge off by any chance? i would compare it with at least another one or a few.
i have 3 trusted gauges i use to verify caliberation from time to time. (one digital, two analog..?)

johnxxx

Yeah Kenchan... good point. After I saw your post I was able to verify with other gauges I have that the calibration is spot on. Haven't checked this in a while but I feel better now that I did and it's in spec.

I use a Milton pressure gauge ( picture shown ).

Still seems weird why at like 33 psi the TPMS kicked on. Once I filled it the light has been off ever since.

Ah, I move on.

Nice little digital tire pressure gauge I picked up off Amazon for $11. Rated #1 and a best buy from Consumer Reports.

BTW - I learned that your tire gauge should be kept inside (not in a hot or cold car) to give you the best precision and accuracy.

I'm running 35 all around but was wondering if I should run a little higher on the Michelin PSS since they're softwall?

It really depends on what tires you have on your Nissan 370Z. I run 34 psi. all around.

littlejuanito

I have PSS.. can/should these be run at higher psi?

Hot pressure should be around 37-39 psi. 33-36 is about optimal cold temp (lower if hotter ambient temps)

If you're not reaching 37psi hot, you should raise the cold pressure until you can. 42psi hot is about the highest you should go in the rear. With the G we have a bit more weight so it can handle up to 46psi before things start to get squirrelly. From experience i wouldn't recommend that 😁. I dont know if the Z would handle that well since it has about 200ibs less weight. Larger tires could handle it, i wouldn't try it with 245's.

Cold temperature is room temperature to freezing. Good luck driving summer tires in freezing conditions
