Pneumatic jockey wheel

[vernon]

Does anyone know what tyre pressure should be in a pneumatic jockey wheel, please?

 

[WatsonJohnG]

If its a plastic wheel 30psi

If its a steel wheel you can go higher.

My steel wheel tyre had max 4 bar on it.

When I tried this with the plastic wheel the wheel (not the tyre)exploded !!

stick to about 25psi we use lots of 10" pneumatics at work and this pressure allows give in tyre so as not to puncture easily.

There's no point in having a very high tyre pressure in a pneumatic jockey wheel because if you have it really hard, you loose the advantage of compliance of the rubber and you have, in effect, a solid wheel.

hi replaced my hard jockey wheel with an alko pneumatic jockey wheel instruction's quoted 30lb psi cheers peter

There may be no point in having high pressure but when its embossed on the tyre it tends to suggest that is what you should use.

The pressure embossed on the sidewall is the maximimum pressure for the tyre - ideal operating pressure may be much lower than that.

Very true Roger that's why it says "max pressure"

Sorry everyone! - but I only started this thread because there is nothing on the side of my tyre!!!!!!!!

The same thing happened to me Roger and I checked my old steel wheel tyre only to see " Max 4 bar"

When I foolishly tried to put this into the plastic wheel it exploded at just over 3bar

It is ridiculous that the plastic wheel tyre is not marked as well in these litigious times

So you were wise to ask !!
