Changing Air In Tyres (1 Viewer)

[landtoy80]

So heat up tyres, do an air exchange and water/moisture will be gone, right?


And you'al thought this was one of my worthless funny threads


Do I do an air exchange or flush?

I go out to AZ every so often to fill up my t*y*res (ain't I sophasticeted too?) with desert air. Prevents rubber rust...!

To do a flush,it would need double valve stems on the rim.
Boy, would that confuse the flunky tire changer boy.

What about toyota OEM Air. I try to keep my Cruiser all toyota.

On a serious note, I was at costco the other day and noticed that they sign says they are filling tires with nitrogen now. So don't laugh, apparently it becoming mainstream now.

Fresh Air

Every time I fiill up.

Interesting. My guess is this is to stop any rusting of steel rims. With tires filled with nitrogen it would stop any rusting wouldn't it? Since rusting is the oxidation of the metal, well, if there is no oxygen...??

So do you guys do a complete air change or do you feel that replacing half the air with new is okay? I'm guessing if I change it on a regular basis, I'd always have semi-fresh air, right?

Somebody should do the math but if you replace 50% of the air at each oil change then after 6 months you'll probably have about 83% new air.

Im headed to Japan next month so maybe we can get a group buy together for OEM air both tires and tyres . Only thing is that it will be marked PS and DS and you will have to remember that in Japan they are right hand drive so you need to put it in the other side then what its marked . Also if theres enough interest I'll also pick up the very rare spare tire air for swing out models so if you now have a custom rear bumper with a swing out this is a "must have" now since the under truck spare air is not suitable for direct sunlight .

Yall have it all wrong as there is a much more simple solution. As old air is laiden with moisture it is much heavier. One needs to deflate tires with the stem at the 6 postition. Then roll forward so the stem is at the 12 position for airing up. The next logical question would be " if they are deflated why does it matter what position the stem is in for inflating?" Well, you truly wont get all the heavy air out and you dont want to mix the two So all the air will be replaced after two times..... but then the first time air is old. Crap

Tires tend to breakdown from the outside before they do from the inside. You want them to last longer? keep the UV rays off of them.

But, YES, if you want only the very best for your tires, you can fill them with 100% moisture-free nitrogen. Race cars often use nitrogen so their tires will be less temperature sensitive. It's the heated moisture that causes the expansion. Air is already something like 80% nitrogen.

You'll see race wheels with two valve stems. One for adding the nitrogen and the second stem to release the displaced air.

Nice Hoser, quite a smart fella. I thought i was the only one who knew that.

Stop it!

I think that helium is almost as good as air from Japan, sure getting mixed up with RH and LH may be a big problem as the side that is lightest tries to turn the truck over but get it right and the sky is the limit. Extra ballast is necessary and an aviators licence may need to be applied for, but hay it would give rock crawling another dimension. Extra care when communicating with other high flyers is needed here, as the Donald Duck voice is likely to cause offence with the aviation authorities so airing down or should I say hiliuming down does need to be don with care . The biggest advantage though is 9000 pound boat haulage becomes a reel possibility for all and not just the bold. Wheel change over is a breeze as the spare just floats on to the wheel studs, ruptured nuts would become a thing of the past, Perhaps the group may get a big discount we purchased in bulk. I there for sugest that this is placed in the wish list.

Anyone tried the synthetic air? I've heard good things about it, but haven't tried it myself. If you are using synth-air -- do you find that it's leaking at all? The one down-side is that some have reported leaks...

Any thoughts or comments?

 

[cary]

The synthetic air is reported to flow better at low tempuratures. I wouldn't bother wasting your money on it, unless you plan to use your truck in temps below 0F.

I read something about this a while back.

If i remember correctly, the idea is that rubber in tires does allow some amount of air to leak through itself. A layer of butyl rubber is used to slow down the movement of air through the tire.

However, different gasses have much different rates of leaking through the tire. So, my guess is that hydrogen would leak through the easiest (being the smallest gas), and with increasing atomic weight, the leak rate would decrease.

All just opinions and faded recolections.

Haha, I know a little about on-road vehicles. But around here, I'm useless.

Has anyone sent their used air to a lab for analysis?

Junk was going to send his air in for testing but since it was declared as Haz-Mat, he couldn't ship it.
