I would stick with the Insa's. I don't see us having to cross much deep sand. From all the pics and video it seems more rock, gravel and just plain dusty dirt. There will be some small dunes and sand areas on my leg, but I am just going to air down. If we were looking at Algeria or Tunisia, I would say go for a better sand tire. Tembo is running his original military Michelin XZLs and I won't be changing. At worst, we have lots of other vehicles to give a pull, so shouldn't be much digging.
