wow... lots of bad info in this thread... I've been running the NV desert for...ten years+... sand/dirt is not the evil most claim it to be, like tiger said keep a clean well attached air filter and clean/lube your truck/buggy every outing you'll be fine... no need to clean it every run... hell I'd have given up years ago if that were the case! I run mostly in the desert... dry lakes, the dunes or where ever my Jeep happens to take me for the weekend... never had a problem related to the environment I run in... since your running in the area you pictured you can go with anything you want... me I find MT's or 1/6 gassers suit me best... lot's of power or ground clearance works for me
