Changing the air in your tyres

[mccool]

Agree with all the stuff in the other thread about how important the right tyre pressure is. But how often do you change the air in them completely? I reckon air thats stuck in a tyre for a long time gets over-compressed and looses its pnumatic qualities. I'm gonna let the air out of my tyres and pump them up again and I'll report back on the difference. Or maybe I'll wait til I'm tuning the hydrocilator and do it then.

Personally - I wouldn't bother and IMHO you would be wasting your time.

Just make sure the pressures are constant and ride it. I don't think you would notice ANY material difference whatsoever in replacing the air entirely.

Each to their own tho - and if you have the time go for your life.

good 1 wkid don't spose you have tried putting helium in yours by any chance, better power-weight ratio and all that

I thunk that once, but found that just turning it over works well. This is best achieved by spinning the wheels at high speed for a few hours. This can be done by riding the bike, and is less energetic than doing it in the garage.

it's actually the oxygen in the air that lets you (and your tyre) down. the oxygen molecules are smaller than the nitrogen ones, and they escape through the imperfect rubberised container that is your tyre, leaving you with a nitrogen/co2 rich mix (so don't go using it for breathing now

[pete376403]

Filling tyres with nitrogen is a recognised method of reducing tyre temperatures. Maybe not what bikes want, but certainly used in trucking applications.

Also, I have often wondered if there would be a market for importing cans of compressed Milwaukee air (complete with smog) for those Harley riders who want to keep their bikes absolutely 100% genuine. (Must be a bummer having to import oil and gas from the US, though )

Nitrogen is also less affected by heat,therefore doesn't alter the pressure(as much) when the tyre heats up/cools down....
There's a couple of places offering it for cages now....

Have a look at Mangell's Wellington Ride report to see my mate Snuffles "unique" attempt at replacing the air in his front tyre.

In the 1970's it was all the rage and a lot of "gargres" had nitrogen filling facilities, I guess Joe Slobb don't give a fat rats arse if his tyre are over/under inflated, as long as they ain't flat and he don't have to pump them up/change them he's happy. :spudwhat:

I still have the original factory air in my tyres.

It's expensive to get it shipped in from Italy and getting harder to find NOS air but worth it for originality I reckon!

Please tell me you're not serious??!! Keep that hydrocilator securely locked in your gargre. [Will now mop up spilt coffee]

And that's the *Whoosh* Prize of the year going to wkid_one.

Speech! Speech!

We've just received a shipment of 'Race Air', from the Beehive. Guaranteed to inflate anything beyond reason and being hot it doubles as a tyre warmer.

Typical of an Aucklander to play the race card....



I'm just trying to get my head around a city that has John Banks as Mayor needing to import hot air???

I'm lucky enough to have a freind that imports air from the various ractracks arount the world.
A particular favorite seems to be IOM air -distinctive because of the hint of four leaf clovers and recycled irish beer.
Another favorite is Monaco air but some people can't get over the hint of old money and expensive wine it leaves if you overfill
