is there much gain by nitrogen in tyres
Discussion
Gday
I just read a article in a car mag ..
Stating that drivers have been using nitrogen in their tyres for a while.
There have been pros and cons to this
a Tyre retailer stated
"nitrogen keeps a tyre inflated longer .thereby enhancing tyre life,reducing fuel bills and helping with vehicle handling"
"nitogen lasts about 3 times longer than air in tyres...."
"Nitrogen doesn't expand like air does and provides a better footprint on the road as temperatures increase"
The Cons were pretty simple
"you can improve fuel consumption and tyre life by checking tyre pressures"
What are the forums view?
Also they charge $A 7-50 or £3-00 a tyre
My view is ... "pretty daft" (using Pats jargon)
Most Esprit owners love their cars and there for keep a good check on their tyre pressures,the same as they do keep a "eye or 2" looking at the gauges on the dashboard

Sounds like a load of rubbish to me ! Most likey an idea by someone who sells nitrogen for a living !!

Nitrogen is used in race car tires for none of the reasons you listed. It is used because it has no water vapor in it. When "air" which is mostly nitrogen mixed with some oxygen, CO2, water vapor (humidity) and a lot of other stuff heats up, it expands at a different (higher) rate because of the water vapor. This will give you different tire pressures at temp depending on the water content of the air when you filled up the tire. If you use nitrogen from a tank, then there is no water and you know that when the tire warms up X degrees, the air pressure in it will be Y. Smith had a good discussion on it in one of his Tune To books.

All NASCAR tires in the USA are pressurized with Nitrogen in order to reduce the amount of tire pressure increase from temperature (remember Ideal Gas Law PV=nRT). Increase temp, increases Pressure. The stability of pressure is extremely critical in racing. For civilian use...it maybe a waste of money.
Hi,
Nitrogen has been used in racing and Aircraft tires for decades.
Lack of moisture is a big factor in it's use. In Aircraft operating at altitude, any moisture in the tire turns to ice, either causing serious imbalances upon touch down, or contributing to a tire's brittleness raising the possibility of a blow out.
Also, it works in a high heat environment much better and expands at a lesser and more predictable rate.
When I was a Fleet Aviator, all our aircrafts' tires were Nitrogen filled for the reasons stated above as well as one other. Namely to reduce the risk of fire should the aircraft sustain a blowout upon recovery. With a lack of O², the tires were much less likely to cause a fire if they burst during the trap (pretty common, maybe 15% of the time).
Also, Museums often fill their display cars' tires with Nitrogen to significantly delay the onset of Dry Rot. This may be the only beneficial characteristic for an Esprit owner who's storing their car for long periods of time, but I doubt the tire life would be extended enough to justify the hassle and expense involved.
