Dr_evil Posted March 8, 2012 Report Share Posted March 8, 2012 Nissan do it on the GTR to keep pressure uniform apparently as they say normal air is too unstable Quote Link to comment Share on other sites More sharing options...

Kes Posted March 8, 2012 Report Share Posted March 8, 2012 (edited) I'm staggered air is free, air is also 4/5 nitrogen - what are you guys thinking about - is this the car equivalent of the Iphone 4? It will take a while before we all realise these are ideas merely to get us to spend more. Come on guys get real.

webber Posted March 8, 2012 Report Share Posted March 8, 2012 Its not a gimmik. The tyres on aircraft and racing cars have been inflated with Nitrogen for decades. Compressed air contains water which condenses and expands with changes in tyre temperature, this obviously will affect the tyre pressure, and under freezing conditions affect the balance of the tyre. The benefits of Nitrogen filled tyres on the average joes car will not be great. You pays your money, and make your choice. webber Quote Link to comment Share on other sites More sharing options...

Bloggs Posted March 8, 2012 Report Share Posted March 8, 2012 There's nothing to be gained by putting nitrogen in 'standard' car tyres. Aircraft however have their tyres inflated with nitrogen (so there in no oxygen) to stop them exploding if damaged, plus there is no moisture in nitrogen (unlike compressed air) plus it is less susceptible to temp/pressure variations. :blink: Ouch, that hurt :wacko: Quote Link to comment Share on other sites More sharing options...
Dr_evil Posted March 8, 2012 Report Share Posted March 8, 2012 Even if its not a gimmick as you say its not worth it for the average person, not that I'd consider it anyway but as I let 12 psi out of the tyres each time I go offroad the nitrogen refills might start to add up to quite a bit!

hushpower Posted March 8, 2012 Report Share Posted March 8, 2012 Best thing i have had done to my vehicle for a very long time ,and i thouroughly recomend it. I go over afew speed bumps some severe to and from work every day and were always inflating my tyres to the correct pressure, NOT ANY MORE. Jolts from the humps could be felt up ones back,NOT ANY MORE. I now bounce to work its such asmooth journey,all for £4. Quote Link to comment Share on other sites More sharing options...
Kes Posted March 8, 2012 Report Share Posted March 8, 2012 The title says it all for me. On aircraft fine - there's a logical reason. Since most tyres will be inflated where they are to run the atmospheric variation will be limited but dont take my view - pay you £4 each time you check your tyre pressures, no more stirrup pumps etc you pay to go to a 'specialist'. Its a fantasy for the average guy - I have an old but poky porche and compared to an extra 1/8 inch on the loud pedal this is just not on the radar. I've had this car for 24 years, capable of 160 MPH, 0-60 in 5.3 and just air in its tyres and, amazingly, still here and no major, serious or even noticeable tyre pressure fluctuations. An absolutely amazing concept. Quote Link to comment Share on other sites More sharing options...

mikky Posted March 8, 2012 Author Report Share Posted March 8, 2012 i thought for a quid a tyre it was worth ago....most of the air pumps around here you have to pay for the air,, mikky Quote Link to comment Share on other sites More sharing options...
StuC Posted March 8, 2012 Report Share Posted March 8, 2012 If it's free, take it. Don't pay for it. 'Air' is 79% nitrogen. A good fill with nitrogen from a garage will get you to 95%, the only way to get a 100% fill would be to vacuum the tyre against the rim and then refill. The vacuum would knacker the tyre. All decent garages will have a compressed air system with an air dryer, so no risk of moisture. Air and nitrogen react in the same way to changes in temperature. In a tubeless tyre nitrogen will permeate rubber at the same rate as air, so no better or worse at holding tyre pressure. Pressure is normally lost through poor bead to rim seating. Corrosion to rims /steel is caused by moisture, air dryer solves this. For earthmover tyres with a tube and a long life expetancy of carcass, 'every little helps' so they are filled with nitrogen. I'm not a huge fan of paying for it (as you can tell), but if it's free, take it Quote Link to comment Share on other sites More sharing options...

Diceman Posted March 8, 2012 Report Share Posted March 8, 2012 Ok, I'll try again.... Do you do discount for PW members???? Jeez, you don't want much do you? OK then, buy one get one free, but I will have to charge a £1 per pair admin fee. I can also lend you a sire bean so you can try & breed your own but there will be a £5 stud fee, regardless of results. Happy now? Quote Link to comment Share on other sites More sharing options...
Bloggs Posted March 8, 2012 Report Share Posted March 8, 2012 I might be interested in a sire bean :unsure: Do you do discount on multiple sire beans? Thanks for being v. patient with me, I'm just off to see if there is enough money in my wallet Quote Link to comment Share on other sites More sharing options...
Diceman Posted March 8, 2012 Report Share Posted March 8, 2012 (edited) Multiple sire beans? Steady on, you'll only need one mate, they are horny little beasts. You have to hobble them and use a nose ring to have any hope of controlling them once the smell of in-season young female beans gets in their nostrils. I think with your obvious lack of experience you'd be better off with AI. I have good quality bean juice for only £1 per straw, plus a small fee for refrigerated shipping of course. Full instructions available from my ebay shop. EDIT - you weren't thinking of breeding them for sale in competition with me were you? I know where you live....

Catweazle Posted March 9, 2012 Report Share Posted March 9, 2012 I've had bikes where I could tell the difference when the front tyre was 2psi low or high, so maybe it would be worth it then, but I've never been able to tell a couple of psi difference in a car.
