Simple - kneel on the tube - if your knee makes a big dent it's too soft!!!

The leafield A6 pressure relief values hold pressure up to 2.4 PSI. I presume these were set at a point to suit most tube operating and safety needs?

My current tubes (hypalon) are rated to max 0.2 bar which is 2.9 PSI.

what goes up must come down....

my tube is usually fairly hard in the morning so I have yet to check the pressure...

leafield A6 &A10 have a range from 0.73 psi to 4.98psi with an upper limit of10.54psi for the A3 valve . it depends what pressure valve is fitted to your tube . we normally use orange spring 3.25psi relief pressure

There you go, the dangers of a quick google. Thanks Paul for the clarification. So can we come up with a rule of thumb? My effort... (a bit of care but no responsibility)

- codders knee test if you've got no equipment (pump it up until you can't make a dint in the tube) or
- a pressure gauge set to something your tube manufacturer recommends, or 1.5 to follow the Tilley guideline or between, say 2-2.5 if no other information or
-a pressure gauge set to 2-5 - 3.5 if you like it hard or a mate advised otherwise and
-a hand on your tube while you sort it all out

That should cover the bases!

Remember on a RIB tube pressure isn't as crucial as it is on a SIB. As long as the tubes are hard enough not to flop around unneccessarily then you will be ok - too hard and they are more liable to burst on impact etc.

Because of this and because I have great tubes made by Tilley with pressure relief valves fitted I am not really that bothered by tube pressure. As long as they "feel" ok then they are fine. Only had to put air in them once in the last year - obviously it had vented off last summer and by the winter they were definitely a bit saggy........
