Nitrogen In tyres

[Driver]

Morning,

The Guy at Bob Jane rang me today and asked if i wanted to try out his new service of putting nitrogen my tyres. And I wouldnt have a clue of what it does..

Are there any real benefits from doing this?

LAter.

[gtrken]

if it's free , yes .

If they want money , no.

Minimises tyre pressure build up and lets tyres run slightly cooler.

Keep your tyre pressures up with regular checks and will last just as long

besides , every time you have to put air in , are you going to go back to them ?

Mix air and nitrogen in the tyre and it will lose the effect

Cheers

[surreal]

gtrken has got in one.

If it is Bob asking bet they will want money....

[Birty]

i thought the idea behind nitrogen was that you didn't need to top up the tyres.

[gtrken]

Nitrogen is a gas and leaks out just like air.

hah!

they want $5.50 a wheel

And its free refills after that every 3months - thats how long its ment to keep its pressure

[lowlux]

i couldnt do that as i change the rear tyres once every month

[MIKGTR]

Fhuck thats a load of crap.....they really are running out of ways to make money aren't they!!!!! next thing it'll be 50cents a tyre to peel off the stickers and screw on the valve caps....this sort of crap shiits me coz they pray on people with no idea and give them the old "is your safety worth an extra $5 a wheel" .......wankers

Isn't air mostly nitrogen anyway???

I am no scientist but I am sure air is something like 60-70% nitrogen, 20-25% oxygen, plus other crap.

Yeh but nitrogen is fairly inert.

It will leak out just like air.

Imagine a drink, 80% coke, 20% rum. Mostly coke, but it'll affect you, wherease 100% coke is totally different.

My Bob Jane guy gives free top ups after you use nitrogen.

Im going to try it, you never know if you never go.

It does not leak, if it leaks you have a valve issue.

My mum (driving instructor) has been using nitrogen now for about 3mths. It has not changed in pressure at all since day 1. Previously she had to check her tyres fortnightly because they would loose pressure.

The tyres are much cooler after long drives and the ride is slightly smoother.

When I get new tyres i will deffinetly be doing it.

[MoonButt]

I believe they use nitrogen in aircraft tires. Prolly because they dont expand like air and the pressure in the tires stays constant.

What about Helium? Might make the car lighter!

then you could have a chuff of it & do the chipmunks.

[skyzerr33]

and then turn into the hindenberg with a stray spark

[Munro]

Would add new meaning to the terms -

took off with the tyres on fire &

go for a burn up the track

[Munro]

Actually, Helium is not flammable.

the Hindenberg was full of Hydrogen.

...which is why after the Hinderburg diaster they went to Helium "Oh the Humanity!"

I was offered it for free, so what the heck I did it. Heres a couple of things i've noticed on the GTR over the past week or so. -->NB: I'm no expert

1. Even in a straigt line, the torque split gauge rises about a qtr under throttle. Where this never happened, with air in the tyre, unless it was wet.

2. The ride seems a little harder

3. With the air in the tyres, the tyres felt a little doughy & soft "yes they were pumped, pressure was ~36psi", & the steering a little heavier. Now, the steering is lighter & feels more like pin sharp steering.

4. The rear tyres grip level may have been sacrificed ???

Overall, Im happy to keep using it

As far as helium goes, I know just the song... I think Engleburt Humpington sang it.. "up, up & away in my beautiful, my beautiful gaaaattttrrrrr"

The main points of nitrogen is that it doesn't leak unless you have a puncture or faulty valve, and the pressure doesn't go up as much with heat.

If I can find a place to do it for $5 a wheel when I buy my new tyres, I will definitely be getting it. Mainly for the convenience of never having to top up my tyres.

Meh i just got sik of it.

It juts seems a hassle that every time u gota get them pumped up again u gota go bak to them, and im lazy.

Ild rather just do it when im getting fuel
