Zilla toughness

So i have looked at the Zillas now for a bit and read reviews and posts. I’m thinking on changing out tires to ones that can handle the Oklahoma clay mud a little better than the Artrax tires I have on there now. The Artrax have done well in everything else I put them in but can ball up in sticky mud, which is to be expected. My concern with the Zillas is that they are way lighter than every 6 ply tire I have looked at which concerns me. I do ride trails with jagged rocks and roots and down on the river, and who knows what’s under the water. My thought is it is either that the plys are thinner or they are making the sidewalls way thinner to save the weight. I’ve heard complaints of people not liking how they tend to roll in cornering at higher speeds. I take this as thinner sidewalls. I don’t want to get these tires and the terrain here end up chewing them up. We are also looking to get out to Arkansas and SE Oklahoma to do some riding there as well. Right now we ride on the Canadian river (sand and mud), Cross Bar Ranch (lots of rocks) and Hynretta (rocks and roots) out in Eastern OK just for an idea of the types of riding.

Few others I’ve had my eye on as well if I do switch. Won’t do Bighorns or any variation, since it’s not much difference in the type of tire I run now.
