gumdrop Posted November 21, 2016 Share Posted November 21, 2016 I know pure nitrogen stops my binoculars from steaming up but what does it do to tyres, am I even going to get nitrogen put in them or is it a scam? Quote Link to comment Share on other sites More sharing options...
WispMan Posted November 21, 2016 Share Posted November 21, 2016 I put 80% nitrogen in my tyres and it seems to work very well. I have no complaints. I have a special arrangement for it with my local petrol forecourt. 4 Quote Graham Unless otherwise stated all posts are my personal opinion Link to comment Share on other sites More sharing options...
Tin_Snail Posted November 21, 2016 Share Posted November 21, 2016 A tyre dealer local to us used to routinely fill with Nitrogen (or at least that is what the invoices used to say!!) - I noticed they have stopped about a year or so ago.

Black Grouse Posted November 21, 2016 Share Posted November 21, 2016 I use a mixture of 78% Nitrogen, 21% Oxygen and a selection of other gases - just normal air ! Pure nitrogen has good reason to be used in race cars and specialist application - but little or none for road cars - also makes it difficult to increase pressure for towing or even small increases to maintain standard pressure as ambient temperature drops 5 Quote 2015 VW Touareg 3. 0 V6 TDI + 2013 Lunar Clubman ES Link to comment Share on other sites More sharing options...
Keefmac Posted November 21, 2016 Share Posted November 21, 2016 I'm in the scam camp, unless you can say 1 psi or so makes any perceivable difference. Fair enough for Formula 1 where every hundredth of a second counts but not for a road car, caravan. . As said above 78% of "normal" air is nitrogen anyway. . 1 Quote Link to comment Share on other sites More sharing options...

CommanderDave Posted November 21, 2016 Share Posted November 21, 2016 It's a scam . The loss of air through the rubber is minimal and research has shown that a number of garages rip people off with just plain air . If you want to give money away give it to charity .

Guest Posted November 21, 2016 Share Posted November 21, 2016 Cumbrian air is fresher with additional oxygen! Still only 20. 946% though Graham. I'm happy rounding up to 21%. Quote Link to comment Share on other sites More sharing options...
Coriolis Posted November 21, 2016 Share Posted November 21, 2016 It's not the pure nitrogen stopping the condensation in you binos. ....it's the absence of moisture, which comes about after 'purifying' the nitrogen of the other components of regular atmospheric air. Nitrogen is used for inflating heavy transport aircraft because the absence of oxygen reduces the risk of explosion if something goes wrong. ...it's got nothing to do with how much it stays inside the tyre (although there may be theoretical reasons why it might). For as car tyre it's a complete waste of time - if there are any differences by using pure N then they will be irrelevant in the real everyday world outside the laboratory. Save your money.

micktheshed Posted November 21, 2016 Share Posted November 21, 2016 As already said : it's a misguided scam. The main constituent 'lossed' through the tyre rubber is oxygen anyway I . If nitrogen was so good what happens if one tyre needs re-inflating from, say, a puncture. If inflated with 'normal' air, it would surely show different pressure characteristics. This doesn't happen (believe me) which is just as well for safety reasons! In any case the % in a newly fitted tyre inflated with %100 nitrogen is still likely to be less than %100 as it will not displace all the existing air without attention to detail; something most fitters are lacking in LOL. The use of dry air would presumably have some beneficial effect but I don't see that on offer. Any thoughts on this? Quote 3L auto Nissan Terrano, 2004 & Swift Elegance 530, 2018.

Paul_B Posted November 21, 2016 Share Posted November 21, 2016 If what they say is true, when we blow up with air the oxygen migrates through the rubber so we top up with air a couple of times until only nitrogen is left Quote Paul B . .......Mondeo Estate & Elddis Avanté 505 (Tobago) Link to comment Share on other sites More sharing options...

PandR Posted November 22, 2016 Share Posted November 22, 2016 Costco use Nitrogen as standard and their tyres (installed) are some of the best value I've ever bought. Usually if you buy all 4 you get up to £100 off when on offer. .. Just had 4 fitted to the Sorento for just over £400. Michelins and some of our local tyre dealers who are renowned for their low prices wanted nearly £140 per tyre. Quote Spanish Trip 2020 - - Time to bailout...

Coriolis Posted November 22, 2016 Share Posted November 22, 2016 Hmmm, strictly speaking it wouldn't change the MTPLM. ....but would allow a little more payload. I think we'd gain more payload by having a pee before setting off, but. ...any port in a storm, if you're that desperate for weight 1 Quote Link to comment Share on other sites More sharing options...

Tuningdrew Posted November 22, 2016 Share Posted November 22, 2016 In a previous life when I worked for Laker Airways we filled all aircraft tyres with Nitrogen purely because in the event of a fire an exploding tyre would not aid combustion. When you take the volume of gas in a DC10-30 main undercarriage (that's 10 tyres) its a huge amount. 2 Quote Link to comment Share on other sites More sharing options...

Assuming you've reached the happy state of retirement (mentioning Laker hints at dates).... all aeroplanes over 5700kg MTOM should be using pure N now, for exactly the reason you state. ..may have been only a good idea back then but it stuck 1 Quote Link to comment Share on other sites More sharing options...

PaulJohn Posted November 23, 2016 Share Posted November 23, 2016 . ..but what about helium? It would give us an increase in MTPLM! Now He really would diffuse through the tyre. He is monatomic whilst nitrogen (N2) is diatomic.
