Tire Problem

OldGuy · 03-14-2010, 01:53 PM

My tire pressure light went on today. I checked the tires and passenger rear one is all the way down to 25 lbs. I have 720 miles on the car in 3 months. Do I see the Nissan service department about this for possible warranty coverage if the tire is defective or am I to contact the tire manufacturer directly?

You inflate the tire to the specified pressure.

A properly functioning tire can lose a pound of pressure in a week. You have, have, have to check your tire pressures on a routine basis.

Yes, wait till the tires are cold, then inflate them to the right pressure. The cold weather will do that to the tire pressure. You're most likely fine. IF they do it again, then see the dealer, but I don't think they will.

It was only the passenger side rear tire---all other three were fine. A pound a week pressure loss---Wow. Since the car has spent most of the 3 months since delivery parked in a chilly garage, I'll proceed on that theory, inflate and see. If it goes down again, then I take it from the responses that I DO go to the Nissan warranty service department for possible coverage.

They don't always lose pressure evenly, but it's definitely something that you need to keep an eye on. You'd be surprised at how many people are driving on under inflated tires... I bet it's more than 75% of people on the road!

That's the TPM earning it's keep!!

Nissan does not warranty tires. Read you warranty booklet. There is a 90% chance you have a nail in it with the resulting slow leak. This is a job for a tire store, not a dealership service dept. Get the wheel off the ground, rotate and inspect carefully if you want to check it yourself.

BTW, Anytime I've ever gotten a TPMS warning the above situation has been the reason..

Indeed. But if you never check the tire pressure the TPMS will go off eventually.

Pressures need to be checked regularly (cold) with a quality gauge..

Yup. Once a month at minimum, but IMO it should become part of your Saturday morning routine.

At what low tire pressure does the TPMS light come on???
30psi, 25psi, 20psi....etc. Was unable to find this in the manual.

Dude....everyday driving on roads with their cracks, rills, potholes and debris are going to cause the tire to momentarily deform on the rim which causes air loss. Its part of natural physics for tires to loose air. Over time it adds up to a threshold of pressure loss which will trip the low-pressue indicator.

Tire pressure should be checked every week....its a best practice that most folks are too lazy to do...

Between 25 to 27 psi....

There is a 99% chance there is NO nail and that this is due to everyday normal driving.

I've been driving my car daily since late October and my tires are still 1-2 psi off from normal. I drove my Scion tC for almost 3 years and only added air twice to 3 of the tires (1 tire routinely, slowly leaked air, for whatever reason).

Perhaps I'm lucky though.
