And the measurement device for finding the "bar" on your "tyre" ... do you keep it in the boot?

Well, after spotting a couple of XK's over obstacles one guy had a bunch of trouble making it and I was confused at to what the problem was. Then it hit me he said earlier he didn't air down what a difference it makes uh. During the first day we headed down some long rocky service roads. About an hour into it I got fed up and air downed to 25PSI and instantly my ride smoothed right out and the family was happy again and the wife just wanted to know why I didn't do it an hour ago.
1.5 barrs = 21.7 lbs/in^2
1 barr = 14.5 lbs/in^2
Arrie is our friend in South Africa, so I guess they use barr as their unit of pressure over there. Actually, I wonder why they don't use kilopascals, but it's just a factor of 10.

I air down to lower than 15 psi when driving on soft dry sand ,, I also put it on around 10 psi when going to extreme soft sand and tough areas, and even with such pressure we sometimes get stuck

Don't you risk breaking the bead at such low pressures...?
