Tyre inflation pressures

JP.

JP, Nose = 70 psi, Mains = 65 psi.

Tyre pressures

I’d have thought that sufficient pressure without undue deflection of the sidewalls – with weekly or monthly checks to keep them that way would suffice – whatever that pressure was.

You probably wouldn’t want full operational pressures in them anyway because you are not moving the aircraft around (much?), there would be less danger of an old tyre going Bang and the tyres, and as a consequence, would probably last longer.

Reduced tyre pressures for static aircraft would seem sensible, for a museum, or, ideally, steel or concrete stands to remove the weight off the tyres altogether. In that case, all you would require would be enough air in the tyres to ensure full inflation – without the risk of ‘orrible bangs and flat tyres every so often.

Yes, absolutely – dont inflate to operational pressure – especially as most of the sidewalls will be cracked to hell.

ISTR Hunter mainwheels were 180psi. Tyres were supposed to be good for 8 landings, but very often did not survive 4.

Hunter tyre pressure

I think I’d be a bit scared to wander round an old static aeroplane if I knew there was 180 psi in the tyres just a few feet away from me.

Thanks you Guy’s 🙂

And for what it’s worth….

Another great reason why you may not want to inflate them to ops levels, is
as tires age, it could be dangerous to inflate them that high while on the aircraft.

I’ve heard of engineers being killed while inflating them without the benefit of a safety cage.

Then dont ask – nothing to do with being a DOUBTER…..! Both of us have been doing this for a very long time!

So have the guy’s at the Aeropark, some post on hear and make you look like you don’t know what you are doing…..

I must say that some on this site just read to much in to things, you ask for some help and all you get is DOUBTERS, like Graham Vale says we only needed to know to check.

We dont intend to inflate to the original pressures as we have always inflated much lower just to keep them looking reasonable, we only needed to know to check. We now have all we required thanks.

Calm down, calm down!

When someone from a museum asks what the tyre pressures should be for their aircraft it is a reasonable assumption that they may wish to inflate them to these pressures.

I, for one, are not doubting that you guys know what you are doing but, there’s always someone out there who may well try, and the consequences can very easily, and quickly, be fatal.

As for doubt. What do we doubt? We are trying to be helpful and give a serious answer to a (presumed) serious question and suggest that some caution should be exercised, just in case you didn’t know what you were dealing with.

If you don’t want a correct answer – or don’t like what you get on an open forum – then don’t ask the question.
