Nissan Patrol 4x4 (Africa)

You will have no problems what so ever I did all those places in 2x4 with between .8 and .5 in the tires when you get to real sand like injabane and namib there will be a difference level areas doesn't matter when climbing 80m plus dunes there is a difference
All to do with the amount of throttle at the correct time .....you have a auto remember

I agree with Thinus. Ht tyres work on sand if you deflate them.

Golden rule for sand is momentum and floatation. Too low tyre pressure over prolonged periods will damage the sidewalls.

Also be careful of digging in. There is too much power in a 4.8 auto if you have a heavy foot.
