On our caravan (see Rig Photo) an old Viscount which has had a
suspension up grade, two inch solid axle, leaf springs and shocks, we are running (on it when I brought it) a set of Nankang Supper Tripper HTs, 215/70R 15C, 109/107P, load range D. Max load single is 2271 lbs @ 65 psi cold. Side walls 2 ply poly tread 2 ply poly, 2 steal and 1 nylon...OK....the van probably weights around 1200 KGs loaded So my question is are they ok on the gibber roads going into
Innamincka from
Thargomindah? and what pressure should I run them?
They are near new so really would not want to get new ones. And that size finding an LT 3 ply side wall is a little hard to find so far.
Thanks for an help
Cheers Bruce

The tyres themselves should be OK for towing Bruce, but how
well do you know Murphy and his bloody law.
In "normal" circumstances you will be OK and could probably do the trip 10 times without issues. At 1200kg the van is not particularly heavy.
The one time you encounter a problem, you will have one spare and depending on the condition of the punctured tyre, you then need to assess if it can be fixed and how. (tyre plugs, tube patches, etc)
Are they tubeless tyres, or do they have tubes?
Perhaps a tyre repair kit, (plugs & patches) and one or two spare tubes will give you that extra confidence.
As for tyre pressure, I would start at 28psi for dirt roads and adjust as required after measuring the pressures when hot and applying the 4psi rule.
If they increase more than 4psi when hot, they are running hot and need more air. Increase by a couple of psi and try again.
If they don't show any noticeable difference when hot, there may be too much pressure and you can drop the pressure by a couple of psi to compensate.

Hi Bill, yep I know that guy Murphy, only to
well hahahaha. They are tubeless and I have tyre plug kit. 28 to 30 psi sounds the go, I will be taking it very easy have plenty of time to get out there.
Thanks for your input to Kev.
Gee just watching the price of diesel going up, might not make it to the dirt.
Cheers Bruce
