I would like to know what you guys think about filling automobile tires with Nitrogen. Is it beneficial or no, how much do you know about it and has it made to mainstream public in your area?

Just doing a little research.

Thanks,

jay

I fail to see the point. Air is mostly nitrogen anyway (78.1%).

Edit: ah I see now. Supposedly, it seeps out of the tire slower.

We fill the race tires with nitrogen and it works fine. It holds a steady pressure alot better then air.

The advantage of filling tires with nitrogen whether on Race Cars or Aircraft is that it does not expand to heat like air from an air compressor. All Aircraft Tires are filled with dry nitrogen, meaning there should be no moisture in the nitrogen when it is bottled. Race Cars do the same so that each lap is consistant once the tires are at race temp. Unless you have a supply of Dry Nitrogen, it is not beneficial to fill your car tires with it.

Nitrogen Most nice tire places sell nitrogen now. I doubt in a street car your gonna notice a difference but its cool to say you have racing nitrogen in your tires.

okay, I think i may have phrased my question incorrectly. I am familiar with what it is supposed to do and what the benefits are and how it works ( molecule size is bigger, no moisture etc.) but what I really want to know is do you think it is worth the extra expense. I run a car dealership and my sister store is about to start selling this product. I've read all of the literature and had more science thrown at me than I care for. I googled "nitrogen tire" and the results were either a manufacturer of the machine doing advertising or reporters talking about how much of a rip-off it is.

So again I ask the most knowledgable group of consumers on the third rock, What do you think? Is it worth the added expense?

Well from your stand point as a businessman, I say, if they'll buy, sell it. Wouldn't be the first time a dealship sold something completly useless to the ignorant car buyer.

That's exactly the image I would like us to avoid. We sell Quality products at fair pricing and stand behind what we sell. The "car dealer" image is hard enough to overcome as it is.

Well good for your. If you're near DFW, I'd buy a car from you anyday.

Any chance of a RR discount?

edit: in that case, I'd stick with plain ole air if I was you.

i could be wrong...but isn't filling the tire with 100% inert gas like nitrogen supposed to stop the tire from rotting and rim from corroding from the inside and therefore prevent leaks?

dont they also fill aircraft tires with nitrogen?

i know 21% O2 doesn't sound like a lot...but its also double the atmospheric pressure, so there is a lot more O2 to burn off.

The spike in popularity

The real reason nitrogen is becoming popular is tire pressure monitoring systems. All new vehicles will have these systems on board starting I believe this model year. With that said the reason is so the system does not trigger a warning when there is a temperature change. My new car has it and I can watch the pressures change 2-3 pounds as they warm up. It seems that any idiot will look at a tire that is near flat and drive on it anyway but if you put an idiot light on the dash that same idiot is at the dealer screaming because he has to put air in his tires and thinks there is something defective with his car. Nitrogen reduces these issue as the pressure does not change as much with temperature.

So if you are not a used car lot but a full blown dealership then you may reduce your customer headaches. In Texas it is not as drastic as it is further north so it is only an advantage if you can sell it and make a profit. You will only sell it to the really safety conscious at this point. I would probaly wait and see before investing in the equipment right now. This MAY just be a fad for the service business. As you know any company will sell a dealership any gizmo if they can convince the dealer that it will make them an extra nickel per car.

On top of this you will only get the tire to atmospheric pressure anyway. You will not get all the air out.

PV = nRT

Pressure proportional to number of molecules, temperature. Not gas identity. N2 O2 H2, and He all behave very simular and are approximated well (for our purposes)by the equation at 32 PSI / ambient temp. R is the gas constant and can be ignored for this discussion. Its a shame more students don't stay awake in Chem 101.

Think about it.

My bro has nitrogen in his high performance car tyres for the reason that you mentioned - it doesn't attract the moisture and corrode the belts in the tyre.

I would have thought on the cars that seem to wear these swanky nitrogen tyres that the rubber would not be lasting long enough to find out if there was a corrosion factor!!!!!

nit will not absorb moisture which can cause corrosion not affected by temp change,so tire presure remains the same and wheels and tire monitors will not corrode.inthe long run tires and monitors will last longer and one more + you should get better or more constant mpg.

A positive outlook is all that is required

Excuse my ignorance but is Tire pressure really that big of an issue that the gov't has to step in to mandate tire pressure monitors ? Does this not sound Rigoshdamdiculous to anyone else?
Its almost as bad as those commercials a few years ago on television. The ones that explained what you needed to do in the event you are involved in a car crash and are underwater. How to break the window and cut your belt & get out. I mean really. How many accidents invlove being in the water?

If you are driving your car hard enough to warrant nitrogen use from pressure increases from heat buildup then you ought to take your car to the track and get off the road.

The problem with low tire pressure is the chance of roll over,especially with SUV's. A lot of high end cars now have tire pressure monirors to alert the driver of a hazarous condition.
I guess you wouldn't have have a problem riding behind a plate glass windshield instead of safety glass.

so big brother thinks they need to mandate that people don't have to monitor tire pressure on their own? the car should do it for them? Sheesh, people need to take responsibility for their actions or inactions. If you choose to own a car, you need to take care of the safety systems. That includes monitoring tire pressure.
