It's a bit hard to draw firm conclusions from the amount of experience that most of us are able to gather by ourselves. Everyone knows that retreads are not a good idea in the NT, yet when I did the Oodnadatta Track, the Tanami, the GRR and the Suart Hway in 1999 in the Series III with crossply retreads, I had no problems. I ran 28psi front and back because that is what I always ran. Maybe sitting on 80- 90kph helps.
Maybe the age of the tyre is another factor that needs to be considered when looking at who had tyre failures and who didn't.
My brother in a Ford Patrick had a couple of new tyres on rims ready to fit when he got the last bit of life out of the rears which were legal, but obviously well used.
I think he managed about 5km on the GRR before one old rear was destroyed. He had no further problems after fitting the new rears.
I doubt that the Pink Roadhouse would be looking to give bad advice about pressures. I think that even with modern equipment fitting tyres would be a bit of a PITA. I think they would rather be doing other (possibly more lucrative) things with their time.
