Tyre Pressures and off road vehicles

[Ruby]

Hi Evil Twin, well picked up, my mistake, I got it twisted around when I was typing it up. Good to see someone caught it

I did a little research to see where I originally found the rule and found this review. (http://www.aawen4x4.com.au/index.php...rrent&Itemid=7). Read a little further into it and it looks like they are advocating a 6psi rule for 4wd due to the tire construction. Once again well picked up ET and Tony

Nice tips thanks guys for your input.

Here in the desert in Qatar we had those big old balloon tyres. Sometimes if the sand was particularly soft we took the pressure right down to 12-14 psi.

... You spotted the discussions we were having over in the Auto Tranny thread eh...

What Auto Tranny thread?

Hi all,

After hearing many a theory from many people who all have their own take I spoke to an army driving instructor. His advice to me was whatever your tyres are at height wise from road to rim take 1/3 off for example my tyres on my gq are at about 150 mm if I bring them to 100 and drive sensibly ill go anywhere. HOWEVER if you do choose to run your pressures at this you may need to change your driving style. At that pressure you run a risk of damaging tyres as aforementioned, so you need to keep it steady and controlled. I've never torn a tyre off and my pressure generally on almost all sand is down at 12 pound and I've seen many people rip tyres to shreds at 16 to20 pounds because they drove too hard or just in an ineffective way.

This is only my advice, so take it all in because there may be a better way out there, but give it a go. Experiment and keep changing and see what works for your truck in each terrain.


Happy drivin

Thanks to the OP for this one, Cheers. would have liked to see a bit more on sand techniques.
