Filled Nitrogen in my Opel Astra Tyres. Improvement was very marginal if any...Tyre noise seems a little less and a very little difference in ride quality which could be a mental thing.... Nothing else. Just that I hope they dont leak like normal air.

I'm afraid you will find only a marginal improvement, if any. Normal air is 78% nitrogen and what they give you at these bunks is more like 90% nitrogen! Nobody has even got 98% nitrogen.

I was anyway prepared for this gamble. Wanted to try it out to satisfy my curiosity and if it doesnt work...I would be happier...because I dont have to take the pain to drive all that far..pay 150 bucks and get my tyre pressure checked and levelled .

Why don't you try this out?

Hmmm Nitrogen, heard ferrari F1 cars use Carbon Di oxide, but from where to fill the tyres ??

Home SodaMaker cylinders??

[nithinnarayanan]

Can someone help me with these ?

What will be the reasonable cost of filling nitrogen in the tyres in Bangalore ?

My car being an indica, I drive long distences at the average speed 100~130. My major concern is what will be the consequences if I get a puncture or an air loss amid these long drives ?

[Nikhilb2008]

30/- per tyre.

At such high speeds, Nitrogen will heat up less. If you get a puncture or an air loss during these drives, you can always fill normal air.

It wont make any difference. Just because you have nitrogen in your tyres doesnt mean you will have to fill Nitrogen always. You can mix normal air too, but the point of filling Nitrogen is wasted.

[nithinnarayanan]

Thanks Nikhil for the info.
Can you suggest good places where I can fill nitrogen from

[Nikhilb2008]

Our tyre shop, Madhus Enterprises on Double Road (below the flyover) fills Nitrogen at the aforementioned price of 30/- per tyre.

Due to both, the trye pressure remains constant over larger periods (one needs to check pressure only after 6 months).

Any opinions would be welcome. Chennai has at least one such outlet.

Yeah, Tyrestore on GReams Road has dry nitrogen. Have been using it since 2000 in my old M800, Zen, Ezen, Indica, Indigo, Accent and a lot of other cars

I guess the main advantage of nitrogen in tires is that it does not permeate through the tire as easily as the other gasses in air, hence you tire pressure doesnt drop as quickly as it might normally.
(This can be said to provide better milage, handling, treadware since tire pressure is more likely to be set right for a longer duration)

In addition to that, nitrogen doesnt combine with the metal rims or rubber tire easily. Which could be said to resist corrosion better. (Along with the fact that compress nitrogen wont contain as much water vapour).

Chances are that when you fill compressed nitrogen its actually 90-95% nitrogen, since making it pure 100% nitrogen would be a difficult and more expensive process.

I have never tried this, nor do i know anyone who has... but i see that it is becoming mainstream in some places, including the fact that some tire companies are researching and pushing this concept.

Hope that helps,
cya

yes sir, i use nitrogen regularly! thats once in 6 months i get my tyres checked and the change is PSI is hardly 1 pound or so.

My 02 Indica DLX ran 60K odd kms before being sold off and i ran the car 100% on Michelin TL tyres with nitrogen. I had no punctures!

At Rs 30 per tyre, is it really worth it? What happens to the moisture already inside the tyre? Even deflating completely is not going to get rid of that.

Also, when AIR is free, what is exactly the advantage of getting DRY Nitrogen filled? Is the charge Rs 30 per tyre even for top up? As headers put it, even if one checks only once in 6 months, but spends Rs. 150, isn't filling normal Air economical, even if you have to Tip the attendant Rs. 5 and check fortnight, it still costs only Rs.60.

What I want to know is what is the VFM by filling DRY Nitrogen?
Cheers,

Nothing much

For some people, it is worth it to avoid the hassle of getting the pressure checked frequently. If you fill Nitrogen, once in 10 months or so is enough.

There is moisture in the old tyres. True. But, hat may be 1-2%. Rest 99% is Pure nitrogen.

If you fill normal air, 78% is nitrogen and rest is oxygen, etc...

Some people can find a difference with Nitrogen. Some people cant. This is very subjective. Ride quality is one thing which is very subjective as well. SOme people find the ride to have improved after Nitrogen. I dont know if this is just a psychological effect or whether it really has. Since you cant really determine ride quality in figures, it's very difficult to completely conclude this argument.

See, for marketing purposes, these are supposed to be there selling points of Nitrogen

1). Nitrogen lasts long. This is proven and 100% true. It doesnt deflate as easily and as quickly as normal air. Please dont ask me why! I dont know. But I do know it does.

2). Corrosion -- Since inflating your tyres with dry nitrogen minimises the water vapour present, lesser chances of corrosion on the insides of your wheels. Of course, with alloy wheels, this is reduced to a large extent anyway. And people with steel wheels generally dont use Tubeless tyres.

3). Nitrogen heats up less --- Again true. However, this wont have much of an effect on the day to day use of your car. One good thing is that if you are driving fast, your tyres will heat up less from the inside. Because of that, the pressure builds up lesser. So, if you have filled 33psi(on cold tyres), it will be 33 only even after running at high speeds or while you are running at high speeds. Risks of a blowout are much lesser.

Useful only if you do long distance driving. In city driving, hardly makes a difference.

4). Oxygen can also corrode the rubber over a long time. Using dry nitrogen prevents this.

These are the main advantages. It's upto the customer whether he thinks it's worth it or not

Well said.

I found Dry Nitrogen in Kalpetta (Wayanad) during the last trip home and filled up all 4 tyres for Rs.200. One thing is for sure - my tyres run much cooler, and this helps because I'm mostly doing high speed highway runs.

The dry Nitrogen absorbs the moisture. One need not check air every month or so.

The ride becomes marginally smoother as absorption of the bumps is better. But some cant feel the difference.

It is VFM as the tyre life improves, run cooler and avoids moisture! And does not BURST in case of a puncture!
