xscreamsuk Posted August 2, 2006 Report Share Posted August 2, 2006 Just picked up a curry, and parked in ATS. I saw an advert for filling your tyres with nitrogen, 5% increase in fuel economy, extended life of tyre, and other extravagent claims made on the advert. Any info?

garcon magnifique Posted August 2, 2006 Report Share Posted August 2, 2006 As long as you don't combine the nitrogen with your curry... Link to comment Share on other sites More sharing options...
NeilB Posted August 2, 2006 Report Share Posted August 2, 2006 Load of cobblers, for normal road use it's useless as the tyres do not generate enough heat for you to notice the benefits. As you top the tyre up it will become normal air anyway, and 78% of the air is nitrogen anyway. Link to comment Share on other sites More sharing options...
xscreamsuk Posted August 2, 2006 Author Report Share Posted August 2, 2006 To answer my own question, a quick google found this. Why fill my tyres with Nitrogen? Why would you want to do this? The benefits of Nitrogen filling are as follows: * Improved comfort of ride * Improved safety * Increased fuel savings * Improved life of tyre Nitrogen has long been the accepted gas medium for filling aircraft tyres, racing tyres and heavy mining and construction vehicle tyres. Nitrogen is used for safety reasons and to ensure that tyres are always at a constant pressure. Compressed air, the traditional medium for inflating car tyres, contains both oxygen (21%) and nitrogen (78%). The rubber tyre is like a membrane, through which oxygen permeates three times faster than the nitrogen. The result is that the oxygen slowly leaks out through the rubber walls, and the under-inflation leads to higher tyre wear with a consequent decrease in safety and comfort, and higher fuel costs. Got the above from black circles, my question now would have to be how do they get the air out before putting in the nitrogen? Do they have a vacuum pump?

R32North Posted August 2, 2006 Report Share Posted August 2, 2006 Nitrogen is more stable than Oxygen when heated and hence a better choice for putting in your tyres, however due to the condition that many poeple let their tyres get into, the less than perfect suspension found on mass produced cars, the state of our roads and the fact that Mr Joe Bloggs wouldn't know the difference or give a toss, its not likely that mass nitrogen tyre filing will come along any time soon. PS - I use Nitrogen in my MX shock for that very reason! Link to comment Share on other sites More sharing options...

Rustynuts Posted August 2, 2006 Report Share Posted August 2, 2006 Just a point of interest, if I went into Kwikfit and asked for nitrogen to be put in my tyres how would I know it was nitrogen they put in there and not just normal compressed air?

Milo Posted August 2, 2006 Report Share Posted August 2, 2006 If you let it all out and breathe it in, you'll speak in a very deep voice. You'll then know that they had used nitrogen Link to comment Share on other sites More sharing options...

Milo Posted August 2, 2006 Report Share Posted August 2, 2006 That's helium. That makes your car lighter hence the claimed bhp increases of 6-9 bhp. More if you also buy the £29.99 beaded cushion upgrade. Link to comment Share on other sites More sharing options...
