. Now about to do Strezlecki Track, Cameron's Corner etc, and wanting to get new tyres.
I have driven twice over those roads in my Hilux and saw 2wd family sedans on them.
I have also been over the Oodnadatta track twice. I was using standard size Goodyear Wrangler TG tyres on one of them and street tyres on the other. Both were running on hand book pressure's.
The tyres you mentioned should handle those conditions easily. You may get a puncture but that can happen to any tyre, even a 7. 50 x 16 MRF cross ply. They are used extensively on Outback stations and unsealed roads because of their puncture resistance. The sidewalls are about 1 inch thick.
When you get out in those areas, it is not a bad idea to know how to repair punctures properly from the inside. Just about everyone, including me, carries those temporary externally applied plugs but they can not fix every type of puncture and are not legal on the street.
I recently got two punctures from screws in my home town. One was in the centre of the tread so I fixed it from the inside with a Rema Tip Top combination plug which is a round rubber plug with a rubber disc attached to it.
The other one was also through the tread but so close to the edge that I had to use a stem plug due to the angle of the hole. A stem plug is just a round rubber plug with a separate round disc.
I also carry internally applied patches that can fix sidewall tears up to 80 mm long. Holes like that can come from things like consealed sharp tree roots or rocks.
A patch on a hole like that can not be used on the street but it will get you out of the bush.
If the tyre is expensive, not very old and worth saving, you can take it to a company that does major repairs and get it fixed properly. They will remove your patch, install a new one, fill the hole with uncured rubber then vulcanise the whole lot together That should last for the life of the tyre.
Have a look at the tyre section on the Beadell Tours Web site. It takes forever to read through it but you will learn a lot from it.
