Kranky, you're dead right about the deflating worries. My father used to run 12-15psi in his series 2A landie, never had a problem (mind you, with a top speed of 80km/h on a flat road there was hardly an issue with overpowering the wheels!) and had to go to 8psi a few times on the north western beaches of Fraser which have now been closed for many many years. It's really that simple, and until you've done it you won't realize how much difference every 2psi makes. It's a question of heat build up and how far and fast you intend to drive. A 12v portable air compressor should be as mandatory as a bull bar (or any other accessory all the popular 4wd mags tell you that you need) when driving on sand, and then it's not really an issue. Which would you rather do - spend 10mins deflating your tyres the extra 4-6psi, then 20 mins re-imflating, or ???hrs digging yourself ( and others if you're in the mood) out of a preventable situation in the heat. I'd choose the first option and enjoy a few coldies in the mean time....
