Quick Question on PSI inflation vs Tire Setup brands

MagmaRed370z · 03-01-2016, 11:23 AM

Quick question guys,

On the door Jam, it says 35 PSI on four corners on stock tires.

1) Does it need other PSI settings when you change to a different tire set, lets say Potenza's S04s?

2) Is the PSI tire specific?

I recently got them installed and they put 38 PSI on the rear and wanted to check with you guys if that's OK or should I decrease the PSI to 35 as stated in the Manual?

typically tire shops just throw air in to get you out. mine were anywhere frome 32-39 last time i got my tires swapped lol

Eh, so many factors. Do it if it gives you peace of mind. I wouldn't care, unless that was my ' I just woke up in freezing weather and measured psi in my tires' setting.

35 is just a baseline setting. if ure not picky just use 35. if u are picky u will know how to adjust the psi front/rear to ur liking.

MagmaRed370z · 03-01-2016, 12:51 PM

Adjust as desire is what I am taking from the responses. So basically >35 <40.

the tires should show you the MAX pressure. so yea don't go over that cold...

on another note find what works for you. each tire will handle differently under different settings/set ups. brands/makes/sizing...

just feeeel it.

mishuko · 03-01-2016, 12:59 PM

heres what you do. set your pressure. drive a tank. change said pressure and then figure out if you notice anything... you'll know what you want.

mishuko · 03-01-2016, 12:59 PM

i do 36 in my fronts and 38 in the rear.

less pressure = more grip for the most part.

i run 32 in the rears and 32-34 in the fronts.

kenchan · 03-01-2016, 01:33 PM

yep, i recommend a lower psi for the rear on a RWD car.. if u want more grip.

kenchan · 03-01-2016, 01:34 PM

on my DW tires i run 37-38 on the front as they are so soft..

but that makes it more fun around corners!

on another note, higher PSI has relatively less resistance = better fuel economy which would be better for long distance highway driving. up to a point.

then again with gas being so cheap... if you cant' afford an extra buck then go drive a prius.

its all give and take. ends up just being up to your driving style and preferences.

As others have said, the ideal pressure depends on which tires you have, how you drive, temperature, &c. For tires that are similar to the OEM ones, what's on the sticker is a good place to start but may not be exactly what you want. Get a good tire pressure gauge and play around until you find your sweet spot.
