I had a nail in my tyre and went to a local tyre place to get it fixed. They charged me £1.50 (plus VAT) for Nitrogen, probably because I picked up a leaflet about it. It claimed to not loose as much pressure, but 2 weeks later checked and pressure was down as it was pre-punture.

 

Good vid. I'll stick to 78% Nitrogen that's FREE.

Middle aged Aussie male - don't trust him :p

 

Sent my Sister off to my favourite tyre place for some new Michelins.  She came back with Nitrogen & a wheel alignment as well.  I was spewing as they aren't very good at alignments and I'm not sold on Nitrogen.  She was happy as they'd quoted the cheapest price (AUD1200) in a 50km radius and when she arrived the price had dropped to AUD1100 and the nitrogen & alignment were only AUD80 so she was $20 in front.

 

What can you do?

The presenter did not have a white coat, you have to have a white coat.  In the bit I watched until I could see he was intellectually challenged and had not mentioned water vapour etc then his credibility had sunk to such a low level I discontinued watching.

 

If someone in Oz just drives within the speed limiits stick with normal air, if you like to occasionally take your car up to 200 or 300 kph across the Nullarbor plain or the like and/or the ambient temperature is 40-45 C then nitrogen might be a good idea.  Having seen cars that hit kangaroos at speed it is a lottery but we do the best to reduce risk hence nitrogen/dry air etc.    

 

  

if my hair spontaneously combusts and my pet cactus dies, I'm blaming you! Stop taking all our Nitrogen

 

 

The elephant in the room is Nitrogen oxides and not Nitrogen.  A little nitrogen leaking from a tyre is no big deal, the nitrogen oxides coming from car's tailpipes shortening the lives of over one million people is much more of an issue. 

 

The US has finally caught on to the particular problem with some imported diesels, particularly VW-Audi, who have tried to evade emission controls to save the expense of the SCR / AD Blu system.

With a Fabia 1 VRS 1 would probably still with plain air.  I had a Fabia 1 VRS Special edition and with a 9 second 0-60, only 130 hp it is not a hot enough car to warrant nitrogen fillls.

 

When I changed to the Mk2 fabia VRS with 180 hp, 0-60 in 7 seconds I noticed that the front tyres got very hot, too hot to touch.

 

Only used nitrogen fills in the petrol VRSs where the performance of the car was of a level to substantial heat its substantially beyond ambient.  

Okay... in some specialised areas such as drag racing circuit and the like where the tyres aint normal road tyres and things need to be very consistent at all times i can maybe see the point re nitrogen.

but for 99% of normal day to day driving imthe effect is goig to be non existent.

lol lol, say in your last post about having a tyre going pop due to over pressurising due to normal air but said previously you inflate your tyres to a level which, when they get hot, will have that much close to blowing due to the pressure ?????

 

I do not know if you have ever measured your tyre pressures when hot but it will be a few PSI higher than ambient.  

The adding of a couple of PSI when you do a journey with high loads or high speeds or both is to reduce the heat generated by tyre hysteresis during the journey and therefore the running hot temperature could be similar, or even lower, of a tyre that started at a lower pressure.

So are you saying that by me fitting my bigger MP Exhaust I'm really saving the planet because I am feeding more plants. Although fat plants are not a good idea imho or are you saying Elephants are causing pollution in our cities?

Of course Nitrogen is a scam the F1 people use it & they know F all when it comes to car design...................

Quote:- "Formula One tyres are normally filled with a special, nitrogen-rich air mixture, designed to minimise variations in tyre pressure with temperature. The mixture also retains the pressure longer than normal air would.

 

 

I remember talking to a mate I knew back in 1994 who used to go rallying & was a test driver for Mitsubishi & then went to Ford, & talking about the advantages of "dry air" & Nitrogen.

 

Same old "it must be snake oil lot"...................

Or just that many are not Servicing Jets, Top Fuel Dragsters or F1 Car Tyres.

Agreed, but to state it is a scam is false, the science proves it works & has benefits in the extreme.................

 

 

Do I use it?.........no, do I deflate my tyres & reflate them on a hot dry sunny day?.............yes...............

How do they fill the tyres? Is the normal air removed and then 100% Nitrogen filled or is it filled from atmospheric pressure?

The Elephant sucks all the air out and then does a special sort of sneeze and inflates the tyre with nitrogen oxides which is the kissing cousin of normal British nitrogen.

 

 

hth

A nice experimental comparison of thermal expansion N₂ versus air versus CO_2.. (Scroll down to "The gas test", subtitle "Ideal Gas Law Formula Shmormula" )

Just in case anyone believes that nitrogen has some physics-defying thermal stability.

Free at Costco so ill get them to fill it so i don't get my hands dirty... and use my membership

They stick all four tyres onto a little pump machine, whilst still on the car, which has nitrogen bottles in and basically they deflate all 4 tyres and re-inflate with nitrogen

They will then tell you to pop in once a month or so and they will check your tyre pressures and re-inflate as required "free" or that's what my tyre place offer. I know tyre pressures should be checked more often but who does in the real world, so once a month is better than virtually never!

Simples just pull up let the nice man or lady plug all four tyres on, they set pressures and it checks them and they do a tyre inspection and off you go again!

My place when you get new tyres insist on a full clean of the wheels with soapy suds/fresh water, remove all excess soap from fitting and even dress the tyre with some the black

Nice where you can get great service like that and still purchase tyres at reasonable prices.

Most places i know are very busy working and earning and offering a good service, but you need to wait to get Tyres fitted or repaired unless booked in as the operatives are knocking their pan in from doors open until closed.

Very true George, I have 4 tyre fitting places near me (most likely within a square mile), 2 of the big players and 2 small and they are always banged out and rushed off their feet.

 

Good for competitive pricing though!

I wonder if I filled tyres with 'Helium' that car would be lighter and go faster...LOL

FTFY

I wonder if I filled tyres with 'Neon' that car wouldn't need lights...LOL

A completely deflated tyre (1 bar absolute, 0 bar gauge) still contains almost a third of the gas that it will when inflated to 2.2 bar (gauge) or whatever. So your lovely pure nitrogen is contaminated from the get-go by the residual air, isn't it?

I was amazed at an American Ford/Hyundai dealer the other month to see all the new delivery of cars have the air sucked out of the tyres to total deflation and then replaced with Nitrogen.

 

Why bother, it's not like we're racing with the tyres at critical temps is it?

I am amused by the nitrogen defenders here. The guy isn't saying most of what they say is not true, he is just, using basic physics and mathematics repeatable and provable by anyone (unlike people's impressions/speculation), saying that the gains are so miniscule that for the road its not worth spending money on. His final point about idiots thinking that because they have 'pure' nitrogen they don't need to check tyre pressures is the most important one, I think. Its your money, fill them with nitrogen, carbon dioxide (even better than nitrogen!) or whatever. But still check your bloody pressures!

 

Regarding aircraft tyres, they are not so much filled with nitrogen as emptied of oxygen (the regulations state a maximum allowable concentration of O2) to reduce the chance of the tyre exploding from the sudden forces on touchdown when the plane lands.

 

And F1 teams, well they have millions to spend on making the perfect rivet, so filling the tyres with nitrogen for the small gains is peanuts.

I really couldn't give a monkies about this nitrogen thing I was saying what my local garage/tyre place do to fill your tyres with nitrogen in reply to the quote in my post and the after service if you want them to check your tyre pressures, I did not say I have my tyres full of nitrogen, although it seems I have

Life is full of so many things and nitrogen in tyres and the air I breathe is one of them, life's too short to worry about how contaminated my tyres may or may not be

Every day, people do things which are pointless and a waste of money. Like people paying £1.50 for a bottle of water when there's a much cheaper option in every kitchen. Okay, so most of the cost is paying someones wages to transport the product, or to have it on their shelf in the shop, and the purchaser thinks that they're getting something spectacular in return for their money, but it's still an extravagance that could be saved. If people are happy to do that, and also want to fill their tyres with nitrogen, then let 'em get on with it. Yes there are benefits, mostly for the person selling the water / nitrogen, but let's face it, the bloke in the vid doesn't half love the sound of his own voice...

That is his job / profession and if he was not a Journalist and Presenter he might need to go get another job to earn a living,

Tyre Fitter , Car Salesman , Delivery driver type work comes to mind.
