Are original general grabber tires suitable for Simpson xing

I agree with Numpty on the pressures, I haven't had the chance to run the 130 on sand since I've had the 255s on it but have crossed the French Line on 235s running tubeless on the original 6.5" rims and the Hay track on 7.50s with tubes. I think when tubeless I ran 20 front and 24 rear. With tubes however I had to run 33 in the rear due to tube problems. At no time did I get stuck (except for a brain fade in Lake Poeppel) and only needed to reverse down a hill on the one occasion trying to get up the northernmost climb on Big Red (got up every other one okay). Had to drop the rear to 26 before it would climb it.
Also I think a lot of people confuse momentum with speed.

looking at reports of road conditions in the Simpson at the moment, I'd be running mud tyres....it's pretty wet :wasntme:

When letting tyres down for sand driving, I usually start at 22 and so far, have not had to go lower.

Keep in mind we were towing a trailer which is a huge dead weight

We also went QAA, french line, down to the K1 line then the rig road

None the less, I'll stand by my comments, tyre pressures need to be LOW, my old boy was worried wehn I insisted we keep so low, up to mount dare, then all the way to oodnadatta, without a puncture on 285 pro comp X terrains...and he's travelled the simpson before, Kimberely, Cape york and the Canning

That's much the same pressure as I ran on the Madigan, Hay River and QAA Line - we didn't have permission to traverse the Qld SD NP so finished along the QAA.
No trouble cresting the sand ridges (not dunes) and negligable wheel spin.
Tyres were 235x85x16 BFG AT's.
