Tire Pressure Monitoring System

[Clue]

Short question, but I know the 2009 Rogue comes standard with the Tire Pressure Monitoring System and was wondering where is it located in the trip computer? Picture would be nice. Thanks.Anybody else get there tires filled with nitrogen? It's a good thing my dealer gave it to me for free, very useful than regular air.

The TPMS system used on the Rogue does not display air pressures... unfortunately. All you get is a warning light on the dash when the pressure drops below 26.5psi.

There is lots of more information, read the TPMS System FAQ for all the details.

Nitrogen is OK, but personally I would not go out of my way to pay for it. You should be checking your tire pressures on a regular basis (ie. every week) anyway.

You just have a light which will be bothering you during winter, either because it is cold outside and the pressure will artificially drop in your tires triggering the light, or because you did not have the sensors on your winter tires therefore...light on.

From what I gathered is good to use (not mandatory) nitrogen for SUV (heavier vehicles) and for those who are doing a lot of mileage.It is Yes for me for both questions so I put nitrogen in my tires and I am very happy of my investment (one big $20 bill): After a winter storage, there was still air (nitrogen) in my tires when I put them back and lost only 6-7 psi... of air since they did not want to put more than 35psi in them and I filled them up to 42 with air.

I couldn't not do it on my wife's huge odyssey van as we only have one set of rims (it is a lease) and we did not want to pay the extra $ twice a year for that. So I check her tires pressure regularly.

It is one way or the other, it is your choice.

Here is an interesting link regarding the use of Nitrogen in long haul transport trucks:

http://www.tc.gc.ca/programs/e...g.pdf

It was a project partly funded by Transport Canada. Although some of it does not apply to passenger vehicles, it does demonstrate the benefits of nitrogen use.

Passenger car tires are not built to the same specs as transport trucks and generally do not last as long. I feel the issues surrounding tire degradation specifically may not make much a difference over the short lifespan of a passenger car tire... typically 3-4 years or 48,000mi (80,000km). Perhaps those who drive very little could reap some benefits as they may keep their tires much longer (time-wise).

I still strongly feel that proper inflation in general is more important. Using Nitrogen as an excuse not to check your tires as frequently can negate many of it's benefits.

If I got nitrogen free or at minimal cost for the life of the tire, I may consider it. It would also have to be convenient for me to get nitrogen refills when the pressure is low.

Don't forget that after 5-6 years, tires are not good anyway because of the nature changing of the rubber due to the effect of light.There may be a safety issue driving more than 6 years old tires.

Filling tires with nitrogen doesn't mean that I don't check them regularly... that just means that I don't have to fill them up every month

That was my initial complain about it, but as the mechanics said to me (and now, I can see it is true): The pressure will never be low with nitrogen, or it means you have a problem with your tire.Anyway, if you need to fill up your nitrogen tires, remember that air is 78% nitrogen already, so when you fill the tire up, most of the job is done. After a while, the oxygen goes out of the tire and the nitrogen percentage rises.

If you don't want to wait too much to have "naturally" tires with nitrogen, you find a mechanic who have a bottle of compressed nitrogen (not the ones with a machine extracting oxygen from air to get nitrogen: not good enough): it is faster.
