There was a column in today's Hindu. Here are some quotes from that article.

Quote:
Generally those going on long drives can fill nitrogen for a smooth ride. Some people use it because it is a light element and it makes handling the vehicle much easier
Hmm. Maybe we should try filling tyres with Helium.
Quote:
Also, with most of the cars using alloy wheels, the radials are filled with nitrogen when one buys the wheels. "Since it is a non corrosive element, dry nitrogen doesn’t react with alloy wheels and rusting of rims is less likely"
Aren't alloys supposed to be more resistant to corrosion?

Run for a couple of days and check.

Just use the N2 pressure reader on all tires.
Nobody is arguing the fact that filling N2 will reduce the amount of air lost over a period of time. It is just that this is the only significant advantage over normal air and all other advantages are only applicable in high stress conditions (F1, Space shuttle etc..).

The only question is - Are you willing to spend Rs 100/150 so that you don't have to check your tyre pressure and top-up every 15 days?

I know one person who would not do it. ME

At least till I see some actual science explaining the advantages.
and not just some feel good factor.

Easy way to Take Off too, imagine one of those wacky tail wings with the turbine thingy and under it written "this is not it! my tires have helium"

Yeah! Pretty common now, but used to be something of a conversation starter when they first came out.

If I had helium in my tyres, I'd be sniffing the stuff all day just for the laughs.

Depends. Did you happen to install a Boeing turbo in your engine?

I think you mean N2O (nitrous oxide). Helium is inert at best.

Since we are talking Helium, Nitrogen and Air. There was a study made in US to see whether a football filled with Helium can be kicked further then one filled with air. The helium filled one went about 1.3 meters(average over different players) further then a air filled one.

So if you fill helium in your tyres then for 4 wheelers - you will go 5.2 meters further for each kick on every tyre and 2.6 meters further on each kick on every tyres of a two wheeler. Note no need to kick the spare tyres.

Now with Nitrogen the only perceived advantage could be it would hold its pressure no matter how many times you kicked it. But you would have to pay about 100 times more for it.

LOL, Spitfire, does it also mean that for each pothole the car will jump 2.6 times higher than if there was air in the tyres?!
And what about the Scorpio's famous sway & body roll? Would that be delightfully enhanced to such a level than right upon ingress a passenger would need a sickness bag?!!

Helium for kicks and laughs?

Whilst people have been known to misuse "laughing gas", the helium means laughs for everybody else, as it makes the deapest voice come out as a squeak. Something to do with sound travelling at a different speed in it, I think?

Oh no. I meant helium all right. Inhale some of the stuff and try talking. But not from your neighbourhood balloonwalla.
I have seen this done in my chemistry lab in school. The results were hilarious.

From Wikipedia:
Helium alone is less dense than atmospheric air, so it will change the timbre (not pitch) of a person's voice when inhaled. However, inhaling it from a typical commercial source, such as that used to fill balloons, can be dangerous due to the risk of asphyxiation from lack of oxygen, and the number of contaminants that may be present. These could include trace amounts of other gases, in addition to aerosolized lubricating oil.

@Thad, @Roy, thanks for the clarification! But this certainly deserves some merit. I can also imagine reduction in road rage incidences and noise pollution. Maybe somebody should suggest this to the F1 teams.

the cost of filling nitrogen is rs 20 per tyre = rs 80 for 4
cost of topup is rs 5 per tyre if you check once in 3 months = 20 x 3 =60
80 + 60 = rs 140 is what you spend in 1 year
if you fill normal air and check once in 10 days = 3x5=rs 15 per month(at least thats what i pay rs 5 as tips to the guy who fills air in the bunk)
15 x 12 =rs 180 in 1 year
so nitrogen works out cheaper than normal air
add to that the placebo or real advantages

IOC opened up their "cool your wheels" at their company outlet near technopark (tvm) There was a huge rush to cross over to nitro in the wheels
