When you talk about business,i believe you need to do a SWOT analysis,to see if its viable. Are kenyans ready to leave free air and come and buy your nitrogen for their tires. Even the president's cars are inflated with air not Nitrogen

Don't sit and wait - look for the next opportunity

@ pm,

the advantages are many but the real reason why nitrogen gas is still not available in our filling stations is the cost factor.....the cost of its manufacture and packaging is astronomical by the standards of an ordinary kenyan...and air is free...


NEVER TALK OF A RHINO IF THERE IS NO TREE NEAREBY - ZULU PROVERB

Personally i'll need more convincing to use the Nitrogen because i think i'm ok checking my tires fortnightly and filling up with the free air. Nevertheless i dont dispute that Nitrogen might be superior.

Becoming number one is easier than remaining number one

@Djinn,first,a bit of correction from my previous post - air consists of - about 1% of water in form of vapor plus other gases, about 21% oxygen which escapes about 4 times more than nitrogen,and 78% nitrogen which is non-flamable and dry ...

That said,nitrogen filled tyres are most suitable for tropical climates because it does not make tyres expand due to varying temparatures,nitrogen is a poor heat conductor,safety is another added plus for nitrogen inflated tyres due to stable tyres and less prone to expansion & therefore blown tyres ... nasgar,airlines,military (us and others) use nitrogen in tyres ... tires will run cooler and at a more consistent pressure than if they were filled with air.

I have a few problems with this:

First it sounds like a 'Mouse-Milk' kind of product. They say that mouse milk is very similar to human mother's milk. Thus if the mother of a child dies,you can feed the infant on mouse milk and s/he will grow normally. The only problem is that it is very difficult to catch one mouse...and you need thousands to feed a human baby....and also you need to make sure that your 1,000 mice are all female and have recently given birth!!!

Of course,it will be easier to look for another breast-feeding human mother and she will only be too glad to feed the extra child....or if in town,buy formula!!!!

Now,the science is not convincing. @pm says that Nitrogen is a poorer conductor of heat than air. This is not true. Thermal conductivity of air is 0.024 W/(mK)....and that of Nitrogen is 0.024W/(mK). They are identical!!!!!!

Their thermal expansions coefficients are also identical; that is,they expand at the same rate as the temperature is increased.

The slower deflation is due to the fact that air has a higher moisture content. This moisture condenses under pressure thus causing the deflation.

Finally,@pm writes ... in most gas stations these days you have to pay about $.75 to inflate tyres,to fill your tyres with nitrogen is about $10.00 and you'll not need to be checking air for a while ... .....

Now in Kenya,air pressure is completely free of charge and you can fill up as many times as you wish as frequently as you need. Many times I have gone with a 'slow puncture' for weeks,just topping-up every two or three days.

Thus,this will only work if petrol stations start charging for pressure.....now that will be the day!!!!

@wachiras;

All tyres deteriorate very fast if used on lower pressure than that recommended by manufacturer.

Low profiles used on proper pressure wear out in about a quarter the time it takes standard profiles.

Now,@200-bob per tyre,how frequently do you re-fill? How will that compare with filling with free airon a weekly basis?

I still think this is another mouse-milk!!

@ wendz. low profile tires are more expensive than your regular tires. they are meant to be used with big rims to pimp your ride. but on the other hand,they are more prone to punctures especially if you drive on very rough roads or over potholes due to the small distance between the road surface and the rim. you may even end up breaking the rim itself. @mukiha. nitrogen solves these problems and you only need to do it once every 3 months or so. plus you could still use regular air to top-up as and when need arises.

...but,come to think of it,a few years ago you could walk into any restaurant/hotel and ask for water...they'd give you as much as you want for free...

Today,you ask for water,the waiter will ask you which brand...and charge you at least 50-bob!!!

So,I guess it's only a mater of time before we start paying for AIR,isn't it?

@pm

This is good information and by the way the nitrogen thing has been around coz in 2006 i went for rim straightening at ..??not sure whether they are called mitchellin kingsway - near Jeevanjey and they were giving out brouchures to that effect but the cost was about KES 1200 for 4 tyres.

They also claimed aircraft tyres are only filled with nitrogen etc - Change management is not easy,but in most cases change is the only constant.

Mukiha,roughly they give 14-17km/l on highway and 10-12km/l town running!!!!

The chief value of money lies in the fact that one lives in a world in which it is overestimated.
