around 70 at normal height,,
I did find left to right required differing pressures for the same height,,
yes I know that sounds stupid,,:angel:

Not at all, my left and right also vary around 5psi.Quote:

A tyre's shape changes on the pressure - the pressure effects it's roundness, as at low pressure the sidewall will bulge out and the contact patch on the ground flattens out and is enlarged, at higher pressures there is less contact patch at the circumference takes a more round shape and the sidewall will straighten up.Quote:

schrader valves in the coin tray:p
I can't take all the credit for it. Phil (DiscoWhite) originally fitted the schrader valves in the engine bay. However, the pipes ran near the exhaust and were eventually burnt through. So I shortened them and remounted them on the side of the air compressor box - much shorter lines so much less change of getting damaged.Quote:

However AFAIK the surface area of the air bag that is in contact with the vehicle does not double, in fact it stays the same. What this means is if the pressure is halved, the bag should only be able to support half the weight.
It appears that this is not the case with your experience, so now I am intrigued as to what is actually going on.
I have a couple of truck valves which I need to manually screw into my air bag lines to manually inflate. A bit of a hassle but it will get me out of trouble.
That probably explains also why so many coil sprung (leaf??) Land Rovers lean to one side as they age.Quote:
