Oh we like a good debate here. Where's Pete Lewis LOL

p.rite.sh

Stopping distances taking bends - I used to throw the beamer about a fair bit and when I moved to nitrogen I could push it a bit further - not massive amounts being a rear wheeler, but noticable enough. Only noticable when the traction control was turned FULLY off...not just pressing the button, I mean holding it down for 10 seconds waiting for the warning & handbrake lights to go yellow.

Nope!

This is what im guessing what happens on the country lanes, after a full day of hammering it in the heat it was noticable with hot tyres.

Thanks

10% extra nitrogen in your tyres? I very much doubt it.

Placebo effect, very likely.

Only those with a CockLink need apply ..... everyone else simply won't be gullible enough - surely to god?

Costco fill your tyres with nitrogen for free if your a member. The guys at my local (rochdale) branch are really good guys. I leave them with my keys and tell them what pressures I would like, get a giant slice of pizza, and come back to freshly filled nitrogen.
The difference the first time was huge, but then I don't what pressures the tires had previously.

pslewis

What difference??

Please explain .....

Rubber used tyres are not impermeable, which means pressure loss can be expected over short or long durations of time. Nitrogen has an extremely lower rate of pressure loss, and will lower the need to frequently add additional air pressure in your tyres. You should regularly check your pressure regardless of whether your tyres have been inflated with nitrogen or air, but nitrogen will definitely have less pressure loss over time.

Nitrogen stays cooler, so your tyres achieve much cooler running temperatures. I would like to elaborate more on this benefit, but since it has little impact to an average driver I will only say this: Almost every race car and airplanes runs on nitrogen inflated tyres. The cooler temperature can sometimes mean the difference between a blow out, and just getting a flat. This also means that reduced temperature equals fewer incidents due to excessive expansion of rubber due to higher heat levels.

Pressure build up: The racing circuit has been using nitrogen to fill up tyres for many years now due to this benefit. Running tyres at higher temperatures also means that pressure begins to well up within the tyre, and once again nitrogen is less likely to increase in temperature opposed to oxygen. Pressure build up again is not a cause of worry for most drivers, but on the race track or drag strip, where tyres reach almost melting point temperatures, nitrogen is almost imperative.


Once you use nitrogen, you have to continue using nitrogen to extract any benefit that nitrogen exhibits. Once you introduce any amount of compressed air into a nitrogen environment, it negates any properties or benefits that nitrogen has to offer.

But usually the ultimate decision we all choose to make, Air is free and it is just too easy to use, so really will anyone actually notice a considerable difference when using nitrogen. So really it is a choice between apples and oranges, or pounds and pence.

Aircraft tyres are filled with nitrogen to help negate any explosive risk due to rapid temperature changes from -50 degrees c at altitude to the +200 degrees c (or whatever the brakes generate) on landing. Nothing to do with the stability of the pressure to within 1 psi. Remember these tyres tend to be inflated to around 200 psi, not 30 IIRC from working on these things 2 decades ago.

Dedrater

The theory is most likely correct. F1 cars probably do gain a few hundredths of a second per lap.

You claim that nitrogen tyres feel so much better going from motorway to country roads and you probably only have an extra 10% nitrogen in them.

It's nothing more that a placebo effect, any thing else is just laughable.

Like all things nowadays when one Genius is "for" some thing there is always another equally respected Genius to be against it

so here is the negative flip to the coin

Thread resurrection!

It's a gimmick for road use, but my road/track Evo I noticed the difference when on track.
Before the Nitrogen fill; after every session on a trackday I was having to let air out the tyres due to the thermal expansion. I'd head out on track with ~25psi and come back 15 mins later with ~35psi. That 35psi did not drop back down to my desired 25psi in time for the next outing - so each time more air was released.
When I got home (car was trailered) they had to be pumped back up, because they cooled down again.

So the logic would say, that with the tyres being over inflated, they are not performing as they should. Nitrogen (nice dry nitrogen ~98%) should help things out!

[QUOTE=his-n-her-scoobs;9454293]Isn't air 78% Nitrogen?




Funny just reading a back issue off " Total Impreza " earlier on tonight regards this very subject and they claimed that you would struggle to notice any difference in a normal road going car as they pointed out that air is 80% Nitrogen anyway- cant argue as not sure myself but having been available for a few years now dont see everyone rushing to pay the extra £4 to have them filled.. !!

During my aircraft days I was taught the main reason A/C used nitrogen is that whilst more stable, it's inert. Much nice having a fair amount of inert gas in a potential firebomb than a load of oxygen.

Exactly how much of a difference this would have made in a fire / crash etc is anyone's guess.

As usual, those who have not tried Nitrogen think it’s a great laugh to have a dig at those who do use it and, in my case, would recommend it to anyone. So, dig away.

I have had Nitrogen in my various tyres for approx. 8 years and 160k miles now and have NEVER had to top up owing to loss of pressure. What I have done, is gone back to my supplier and asked them to increase the pressures for when I go on holiday fully loaded. For those doubters among you this service is free once you have had Nitrogen in the first place and which I normally get thrown in for nothing when buying my tyres. So, a Win Win situation as far as I’m concerned.

Another Win is that properly inflated tyres use less fuel. Apparently, tyres with air in will lose approx 1.5psi per month.

Another Win is that your tyres will last longer because they are running at the correct pressure and wear less.

Another Win is improved safety in that the sidewalls suffer less from flexing and so there is less chance of failure.

Another Win is the time saved in not having to regularly top up your pressures.

Another Win is that who actually checks their tyre pressures every week because I don’t believe you???

Another Win is that Nitrogen is more “Green” as less fuel means less greenhouse gases – OK, Ok, that’s taking it a bit far!!!!

The key here is that Nitrogen is not a magic gas but the fact that it is retained by the rubber much better than Oxygen and Water Vapour. Also, for those of you who say air is 79% Nitrogen anyway, that 79% has Water Vapour mixed in with it along with the water vapour in the remaining constituents and it is the Water Vapour in tyres which can cause significant pressure variations.

PS I find it better to increase normal pressures from cold by 3 or 4 psi when using Nitrogen to compensate for reduced fluctuations when warm.

Over to the doubters.......

come on guy,s who you trying to kid.....
I dare say Alan McNish, Lewis Hamilton maybe even Jason Plato might notice a difference but not Mr Average nipping to Tesco or wherever.
Yes if your running on track you might want to reduce the pressure fluctuation, but even then you should still be checking pressures in between sessions. No hardship letting a few psi out lol.
For all those who say it,s a very noticable difference on the public highway, your kidding yourselves.

Cheers, thought i could hear a sloshing noise on the way to work. It,s that water in the tyres.

Ive run Nitrogen for years. In my Fiesta, My works van and now the scoob.

I evacuate the tyres using a vacumm pump then refill using OFN (oxygen free nitrogen)

I had my fiesta and work van for 3 years and havent touched the tyres apart from when i have new ones fitted of which i repeat the above procedure.

Nitrogen has a less reactive pressure-temperature relationship so there isnt a big noticeable difference between hot and cold tyre pressures, thus improving the grip and withstanding more tyre roll/squash during harsh acceleration, braking and cornering.

OFN is definately the way to go in my opinion
