If thats the case, would the dealer replace without charges ? do you think ? my car is brand new, not even 1k yet

Yes warranty, they would probably reset the ecu to see if it clears it, if not they'll replace what ever sensor is causing it.....

TPMS sensor on one of the tires may need a re-set.

Yeah, or a simple reset on the sensors as noted above. Dealer, or any tire store can do this for you. It's about a 5 minute job

When I brought my car home from delivery, I checked the pressure and it was 40 PSI and I attributed it to idiots at the dealership not knowing what they were doing when they prepped the car. I immediately had the pressure adjusted to the numbers on the jam and have kept it that way since simply because I assume the Nissan people know best. But now I'm going to say the dealership set those pressures at 40 not out of incompetence but for a reason. I like to give people the benefit of the doubt.

Cause they couldn't read the door Jamb sticker?

Seriously, most car and tire combination's have a sweet spot they work best at. Different tires than engineered and spec'd on the car may have softer or stiffer sidewalls that may require a change in the pressures. IMO the factory recommendation with these tires are pretty spot on. Raising them to 40 will result in a reduced contact patch, sketchier braking and traction, and odd tire wear patterns.

The Tyre Bible is always a good read if you haven't done so:

Wrong, NOT any tire store can reset the TPMS on the Z. The Nissan dealer has to reset it.

You must be hanging out in the wrong tire stores. This is not magical technology available only to Nissan. Others have had this done at (well equipped, up to date) tire service facilities.. In fact there's a friends Z sitting on my garage lift as we speak with new wheels, tires and TPMS sensors assembled at our local tire store and all is working just fine..

Wait, you can turn the tire pressure warning on? I didn't touch anything. It came on one day. I check the pressure and got them up to 35 psi and it's still there. Didn't happen with my TL. I guess I have a bad sensor

i run 37.5psi on my hobby cars. both have recommendation of 35psi but it's too mushy for my motoring needs.

in the winter time when i hiberate the cars, i usually put 40psi or more to compensate for the colder temps inside the garage in the winter. about 1psi per 10F change.

Fine... Be sure to point that out to them next time you're at the dealership...

Folks that don't know much about cars are regularly put at risk by bad set-up practices. 45 psi in the tires, Spring shipping spacers not removed, wrong locking lugs installed....I could go on and on..

gumpy · 03-12-2010, 07:06 AM

I always put an extra 2 psi in for fuel efficiency.

I recently purchased a good tyre pressure gauge... many of our local service station air pumps have wrong readouts... but they're consistent at least... My preferred place always has a 1 psi difference to my gauge... dunno which one's right... =/ don't know if it makes a difference...

I was going to raise an exact same thread on this. The recommended tire pressure is indeed 2.4 bar but somehow I find this abit twitchy on our roads and actually like it when I pump it to 2.6bar. It feels stable and suprisingly planted compared to 2.4, weirdly.. it should have been the other way round I would've thought..
