Nitrogen in Tyres? Do you use it?

[240MPS]

You would be absolutley mad if you don't use nitro in your tyres... FULL STOP... I use to tell people they were mad using it, that's when I should of shut my mouth because I didn't know what I was saying, I have been using it now for 5 years and will never look back..... I get more life out of my tyres and the edges last to the end and I don't check my tyre pressures for 6 months at a time and the top ups are free for the life of the tyres....

i was told u could not check the pressure yourself and obviously if it happens to b low u cant top up yourself. but i spose whenever u put your car in for a balance and allignment u could get it checked and topped up then

Incorrect Phil if you are in a position that you need to top your tyres up you can if you are no where near a Bob Jane store, and next time you go to your installer they will release the air out and top it up for you, providing you haven't driven over a nail like I did down the coast last week. They repaired the tyre and fill it up with Nitro for $35 at Mermaid Waters, I drove from Burleigh Heads to find a Bob Jane store still had some pressure in the tyre if not I would have top it up at a servo if I needed to till I found a Bob Jane Store...

Bob Janes does the N2, and its not very expensive (I think its about $3-5 a tyre), which is not much considering the price of rubber these days (decent STI 245/45/18's are friggin expensive!!)

Depending if you know the guys at Bob Jane normally around $5.00 to $7.50 per tyre but remember they top it up for free for the life of your tyres.. I got mine for nothing because they love my business.... I check mine every 4 to 6 months only out by 1 to 2 PSI each time and I run on 38PSI..

This is a very interesting discussion, I haven't used it and until Wardski's post had not even considered there were genuine benefits. However considering the lack of nitrogen filling stations, do N2 filled tyres lose pressure like regular air filled tyres? ie I have to put air in (not much 1-2psi) about every 1-2 months in some of my tyres?

I only lose 1 to 2 PSI over 4 to 6 months Chris..... This should give you better fuel economy with your tyres keeping even temp all the time. That's why they tell you to pump your tyres when tyres are colder at the servos because tyres fluctuate in temp....

i asked about nitro at bob janes and beaurepaires and both people i talked to basically said not to bother. i was curious as weel but didnt end up getting it due to this fact.

Go back and tell him he's a and to go sell newspapers...



I'M ON FIRE...

[tricache]

Good backing up of facts Rino!! This has me thinking of trying nitro next time I get tyres sorted (I'm due soon)

[YOU LOSE]

Thats the way Rino sort em out mate , us oldish members may know a thing or 2

HOW NITROGEN WORKS & WHAT IT DOES

TYRE SAFETY - EVERYTHING RIDES ON IT

Nitrogen(N2) makes up the majority of the air that we breathe (78%) and is contained in the protein of all life on earth. It is colourless, tasteless and non-toxic. The next most common component of air is oxygen (O2). Together N2 and O2 make up approximately 99% of the air that we breathe and with which we traditionally fill tyres.

N2 IS A LARGER MOLECULE THAN O2

Therefore, it cannot and does not permeate as easily as oxygen through porous material such as a rubber tyre wall. Leaking at a much slower rate than oxygen, a tyre filled with a higher percentage of N2 maintains its proper pressure roughly three to four times longer than air-filled tyres. Proper inflation provides better fuel economy, superior handling, longer tyre life and increased safety by reducing the likelihood of low pressure related loss of control, blowouts and other tyre failures.

N2 IS A DRY INERT GAS
O2 in a tyre provides unwanted oxidation. Over time, this reaction destroys the tyre wall and corrodes wheels. A tyre is prematurely aged by O2 from the inside-out as the pressurized air in the tyre makes the O2 try to escape through the tyre wall, speeding up the damaging oxidation process. N2 on the other hand, is a harmless inert gas that does not react negatively with the tyres and wheels. N2 filled tyres also reduce tyre heat, thereby decreasing rolling resistance and increasing fuel economy.

N2 IS NON-FLAMMABLE
O2 is a flammable gas while N2 is an extinguishing gas. Thus, a large number of mass transportation companies around the world fill their tyres with N2 for added fire and explosion safety. In a vehicle fire, ruptured air-filled tyres fuel the fire. N2 filled tyres slow the fire.
N2 has been used in tyres for many years on aircraft, military vehicles, off-road trucks, race cars and
Tour de France bicycles.

NITROGEN INFLATED TYRES ARE SAFER and LONGER LASTING THAN TYRES INFLATED WITH "WET OXYGEN" in COMPRESSED AIR
Nitrogen inflated tyres do not age as quickly as air inflated tyres.
Nitrogen inflated tyres improve vehicle handling through proper inflation and constantly maintained pressure.
Nitrogen inflated tyres minimize blowouts.
Nitrogen is an inert, non-combustible and non-flammable gas.
Nitrogen is a stable gas providing more constant pressure.

THE EFFECTS of UNDER INFLATION ON TYRE WEAR and FUEL USE
It is also the single most overlooked item recognized by service agents during maintenance visits. It is not uncommon to have to add inflation pressures to all tyres.

Correct inflation is highly significant when considering tyre life and performance. It is not always possible to look at a tyre and detect under-inflation. However, under-inflation can cause many tyre related problems. As inflation pressure largely determines a tyre’s load capacity, under-inflation results in an overloaded tyre. An under-inflated tyre operates at high deflection resulting in decreased fuel economy, sluggish handling and may result in excessive mechanical flexing and heat build up, leading to tyre failure.

Great Thread Wardski . I have all my cars on it and my sister in law who destroyed the front tyres on the edges with still 95% thread in the middle now has new front tyres and Nito in all 4 tyres and in 8 months they still look like new.....

[Brackaus]

When I my new rims I ask for N2 as most of my other friends (rice boys etc) they all use N2.

[Wardski]

Sounds like N2 is the biz. I'm going in on Sat to get me some

This is really good feedback guys, altho I expected a little better from Doc lol

Much better for track use to temp doesn't move anywhere near normally air.... Wow only 10 votes ....

yea i was omly going on what they told me as i was ready to get it put in my tyres but was then discouraged by ppl i talked to so didnt bother. would b worth a run though i spose

[owhat]

everytime i buy tyres i still havent been asked if i wanted it. I thought they would have been up selling it like Mcdonalds (do u want fries with that).

[Doc]

I can get it for free.. and I still dont bother...

It doesn't take long for tires to heat up.. and I don't throw the car about till the oil is at operating temp.

The cold tire pressure stated has taken into account the few (2-3) psi increase which will occur when the tires reach optimum temps.

And for what its worth I check my tyres once a month.. and I don't loose two fifths of stuff all.

Take it for whats its worth.

If you want to give it a shot.. fill your boots.

Enjoy guys

Doc

and remember that air is 78 % nitrogen (i think from memory)

the thermal properties of air vs nitrogen is minimal.


Aircraft wheels still fluctuate in pressure after a landing.. this is not rock sold pressure irregardless of temperature .. it defeats some pretty important gas laws
