Can you say front and rear lockers? No tire will do that without them.
I've had to pull guys out of the snow when they thought that's all they needed was their lockers: Too bad they had chitty tires. It doesn't just take lockers to get you where you want to go. Sometimes they are even a detriment. I'll give you credit for maybe knowing what you are talking about since you live in the same high desert conditions I grew up in and I know tires are a huge deal there. I've seen sagebrush go right through sidewalls and rocks just slice a tire like a hot knife though butter. When we were way out in BFE (black rock desert for example) we'd carry 4 spares..
