I've reported the first post to the powers that be to get it moved to Trials Chat.
Bit more on pressure while I'm here- If I run my tires just hard enough not to get punctures, I find the tyres still bounce me around a bit too much, especially on cambered sections, so I tend to run them with a bit more air to keep the tyre more stable. Just preference really- I know people who have run their tyres so low that you can rim out just by compressing the bike with your body weight but that's just too low for me.
