When I bought my DHSE the previous owner had put a new set of Goodyear Wrangler tyres on its 18 inch wheels. They were inflated with nitro(?). My question to you knowledgeable chaps is is it better to leave them with the nitro or get it changed to air. I am told by 2 of our local tyre dealers that if they need topping up you have to use nitro.
 
Nitrogen? I think it is more pressure stable with temperature than air. Pretty pointless on the P38 and how are you supposed to keep the pressures right if you don't have access to Nitrogen?
Personally I would replace it with air the first time the pressure needs topping up, although I can see no reason why you shouldn't top up with air as Nitrogen is a component of the air we all breath.
 
Nitrogen is used because it has no moisture content and no oxygen is presesnt to cause corrosion of the inner wheel beads causing leaks as with air. Also as Data says it is more stable than air when heated. You do not get the same amount of pressure change you get with air, as the gas heats. Aircraft use Nitrogen in their tyres. Can't see it being required in a P38 though, you can top up with air without a problem.
 
Yeah if you get too much Nitrogen in your blood stream it's a bit like smoking a good joint. If your Rangie laughs a lot put some air in the tyres.

Laughing is Nitrous Oxide, laughing gas:hysterically_laughi:hysterically_laughiNitrogen bubbles in the blood stream is the bends, divers disease:eek: As for joints, thats a mugs game.

Nop sorry not so. Narks or Nitrogen narcosis makes you giddy like you've smoked pot. The bends is totally different. That is bubbles of high pressure air in the capillary blood vessels that can't get out if you come up quick, that's why you need to decompress. Used to be a professional diver by the way.

Some of the smart arses with deep pockets used to use it on their race cars, I could still beat them running mine on free air:car:

My little Lotus has got nitrogen in it's tyres...
Plus it's not that expensive and a bottle lasts for ages.
I'll give you a race! I'll even give you a head start!

Bends is Nitrogen bubbles in the blood stream, look it up. As I said, no idea about drug or Nitrogen induced highs that's something I leave to others.
Nitrous Oxide is an anaesthetic also known as laughing gas.

narks happens when ya diving and is like getting ****ed really quickly.The ya buddy comes along and spoils it all by taking you up a fdew metres and sobering you up.BOOOOOOOO!!!!!
 
They tyre place I went to last week had posters up about this claiming that nitrogen molecules were larger than air molecules so they wouldn't leak through the material of the tyre so quickly (ie tyres stay up longer).

Didn't occur to me what bollox that was until now!

Don't need to look it up Nitrogen narcosis and bends are NOT the same thing. Told you i used to be a professional diver. Bends is high pressure gas getting into very small capillary blood vessels. If you come up without bleeding them off by decompressing they expand and do damage. Nitrogen Narcosis is very simular to being drunk. It occurs at depths usually below 100 metres for most people but can effect different people at different depths. Move to a shallower level and it goes away without ill effect. Corsicans for some reason are more tolerant than most to it.

OK well I'm not a proffesional, but my SCUBA course described bends as Nitrogen bubbles that couldn't be re-absorbed if you de-compress too quickly. It said the same when I googled it. Was not a lot of interest to me as I wasn't going deep, just round the rocks and coral:D

Definitions:- Nitrogen narcosis •confused or stuporous state caused by high levels of dissolved nitrogen in the blood; "deep-sea divers can suffer nitrogen narcosis from breathing air under high pressure"

Bends:-
The bends, or Decompression Sickness, occurs when nitrogen bubbles in the blood lodge in certain parts of the body. A bubble caught in a vital organ can be fatal. Before much was known about decompression sickness, divers got bubbles lodged in their joints forcing them to “bend” over in pain.

Nitrogen In the Blood
A diver breathes air from the scuba tank that contains approximately 79 % nitrogen and 21 % oxygen. The pressure of being underwater forces the nitrogen into the body’s fatty tissues. The longer and deeper the dive, the more nitrogen is forced into the tissues. For example, at 10 metres the partial pressure of each gas is doubled, so twice as much nitrogen is absorbed into the tissues as on the surface. At 30 metres, four times as much nitrogen is absorbed.

When the diver comes to the surface; that is, moves from a greater pressure to lesser pressure, the nitrogen comes out of the tissues back into the blood stream. This is like a bottle of beer being opened. The gas is kept in solution by the pressure under the cap; when this is removed the gas bubbles out.


Note that both are caused by Nitrogen.

So all the people that breath Heli/Ox at depth will be happy to know they don't need to decompress because there is no Nitrogen in the mix, so they cannot get the bends, according to your Scooby Do instructor. Well they have to, because ANY gas in the small capillaries will hurt you, or in the lungs cause an embolism that will kill you. Not just Nitrogen. One of the reasons Heli/Ox is used is to get rid of Nitrogen the other is to control the Oxygen content because if you breath more than two atmospheres of that you die. That is why Oxygen rebreathers cannot be used below 60 feet. 30 feet one atm 60 feet two and so on and so forth.:):)

Who mention HeliOX? I haven't a fecking clue about that. I was talking about Nitrogen, the major cause of decompression sickness in SCUBA diving.
You can kill yourself by injecting air into a vein (artery?) no need to go diving.

You should take note. It is things like this you need to know if you reverse off a deep water dock. Never come up faster than the smallest bubble. That's if you can manage to get out of the submerged Rangie that is.
:D:D:D
