Yeh, sorry, couldn't resist the great tyre pressure debate.
Firstly, my experience is as follows.
Been 4WD ing for 25 years. Started when I was 17 in a subaru wagon travelling the
Oodnadatta (when it was graded once a year). Since done it in the Prado 3 times, been to Dalhousie up through to Mt Dare, Finke etc.
Now in the Prado. 2009 took it up the Cape via the OTL loaded with the missus and 3 kids.
Done the
Birdsville (yes it's a highway),
Lawn Hill, flinders countless times, High Country several times,
Robe etc.
So a bit of experience.
I run BFG's all terains. Up the Cape fully loaded on rough roads ran them at about 28 PSI. No punctures.
The mindset of the side walls not coping with the stones is from when side walls were made weak. They now have extra belts and can cope, as long as you adjust your speed.
If you load your vehicle up, have 40 PSI in your tyres and travel rough stoney roads they'll chip out and you'll destroy them. How do I know, because I have done it.
Think of your tyres as a balloon, lower the pressure and they're a lot harder to
puncture because they give.
In relation to the on road van Michael, i've travelled the tracks you will be going on. I wouldn't up grade to an off road model. They're not that much different to the on road model and they still aren't built for badly corrugated roads. If you are going to do a lot of this type of travel, i'd be getting a trailer with independent
suspension. If you won't be doing a lot more of this type of work, stick some good tyres on your van, the bigger the better, stone guards, lower your tyre pressure and travel to the conditions, you won't have a problem.
