I'm happy doing it the way I was taught and the reasons why. normal pressures, high revs, low box works fine

Have you ever driven in proper sand? ie Morocco / Tunisia |

I just find it hard to understand your views against lower tyre pressures when it's well proved that it works  The larger you can make your foot print the better the vehicle will travel High tyre pressures make your foot print smaller. |

There's no appreciable difference. its one of those things that found its way in to offroad driving myth. You get a marginally longer footprint, yes, but its very marginal. that's far outweighed by the risk of popping a bead or multiple beads all at once. The guys I work with who train several forces who operate in the desert are unanimous in this, "dont lower your pressures". each to their own, whatever people want to do is cool, i just wont be lowering pressures, and so far, and after thousands of desert miles, many of which in soft sand I've never had an issue. Give it a go.
a far bigger issue in sand is the weight of the vehicle. a fully laden expedition vehicle will definitely find it tougher going. |

Wouldn't call it a myth as it does work
I ran Staun alloys with the bead locks and dropped my pressures down to 10psi and it made a huge difference. As you say weight is a problem |

My man, you are sorely mistaken. Weight is a factor, but dropping your tyre pressure is a must when going offroad, esp in sand. The rule some people use in SA is as follows: When you go offroad, halve the current tyre pressure. This works brilliantly on gravel. For sand, drop to 1.0 bar, and if need be, 0.8 for very soft sand. |

I know the Dutch army isn't lowering tyre pressure but we had a lot off laughs when they were digging there Merc out when we were driving around them at around 1 bar.
The army does it because the drivers forget that low tyre pressures on the road are dangerous. That 10 times hitting the brake to stop TC working, is that not cancelled when you go over 7 or 10 km/hr like with the Td5's?

the army (various special forces included) doesnt do it because can you imagine a team of guys in a truck racing away from an engagement and being chased? "hold on a minute lads, we need to stop and lower the tyre pressures before we get into the sand"
as I said, each to their own, but I've never had a problem and am happy doing it this way. |

LOL! If in doubt, use the Forces (especially Special Forces) to prove a point...
They aren't always right and have to make do with what they are supplied with. Not always the best kit for the job. I'd sooner take advice from a reputable exploration team/company than the Forces. Defender 110XS SW gone... now VW California 180 4 Motion. |

And again, each to their own. It works fine for me, I'm not sure why thats something to find amusing

How does 1 remove the ABS fuse, is it under the seat or in the engine?

under the steering column, two plastic screws that you can undo with a R2 coin. |
