Nitro tyres

Got a pile of junk mail yesterday but one bit stood out. :o

If you like the idea of hassle free, more efficient and longer lasting tyres, think about inflating them with nitrogen. The big differance with inflating your tyres with nitrogen, rather than compressed air, is that they will stay inflated at their optimal level for far longer. Using nitrogen in your tyres will have the following benefits.

*Better fuel economy as there is less tyre drag.
*Increased tyre life by as much as 30% as your tyres will suffer less wear and tear.
*Provide your vehicle with a more responsive handling.
*An estimated 5% annual saving on fuel consumption.
* Safer motering as nitrogen inflated tyres have a far less frequent incidence of blowouts.

It is because of these superior qualities that formula 1 vehicles and aircraft use nitrogen to inflate their tyres- now its time for you to benefit too.

Any way I was just wondering if this is a good idea or is it just some thing else that will turn out to be a passing idea and a waste of money

good for a drag or race car, not worth in for a 4b or normal car. the claims sound very dubious.

no point puting it in the 4by unless u want to carry a can of nitrogen around with u when u air up after a trip in ur every day car don't see a prob with if it does what it says as a passing fad only time will tell that bob jane has had it for about 6 months now

Recently, I bought 2K of tyres from Bob Janes, a set of muddies for the cruiser & a set of Bridgestone Potenza G3s for my daily Driver.
I was aked if I wanted to fill them with Nitrogen, to which I said, the car tyres yes, but would be pointless on the muddies as I will be letting them down as soon as I get off the roads.

What I have found is this,
Yes they do hold their pressure for longer, they are due for a check again now, but last week were still 32psi
Fuel economy...... I have found no difference, as I always had a weekly ritual at the petrol station, fill the tank, check the tyres.
As for extending the life of the tyre, I would guess they are going to be pretty damn good to get more than 80,000km on a front drive hatch, but we will see how they go. (I also believe that wear is due to not getting tyres checked regularly)

My tip. If you are not going to vary your tyre pressures (like a DD), do it, but if you are changing pressures, it is a waste.

How does it work???

Does give the tyre less flex or somthing?

Just as I was thinking, bit hard to refill after a weekend trip. Got to admit but it sounds like a good idea for the onroad people.

Dont know for sure, try the site but what I put in the first part of this is all they had written about it.

Nitrogen is inert, therefore should react less with the rubber.
It also doesn't expand like air does & it doesn't leak out like air does over time.
Probably the reason I don't get the claimed variation in fuel economy, as I checked my tyres weekly anyway.

Planes run nitrogen as it is inert, so a tyre folded up in the plane doesnt become a bomb from oxygen and flammable fumes from a burning tyre.

V8 Supercars run it because it transfers heat better, so allows a more even spread of heat, as well as getting to and from operating temp better.

It also does not leak as easily as air from tyres [rubber will leak air through the rubber, thats why you need to check tyres regularly] as nitrogen is a different molecular structure to air, and will not expell from the rubber as easily.

I paid 5 bucks a tyre at Bob Jane to get mine done when new and yes they do hold they're pressure better but so what, you check them regularly anyway.
As for the other claims, they must have some sort of proof from testing but I honestly noticed no difference whatsoever with fuel consumption or tyre wear in any way.
As already stated, it is not much good for 4wds as you adjust your pressure often and would usually refill at a servo will normal air.
I think one of the main things is the Nitrogen they use has no moisture in it.
Remember normal air is around 70% Nitrogen anyway.
One thing here got me thinking. What if you filled the tyres with Helium? I reckon being small atoms they would expel quite quickly but if that didn't happen the lighter than air effect and inert nature would be much better than Nitrogen?

The car I used at the time was a Hyundai Excel therefore all road work.

[BigBugga]

Helium? :o

Balloon tyres and an exhaust note that sounds like mickey mouse.
