https://www.csttires.com/us/tire/wild-thang/I have these on my Pioneer 1000. They will definitely sling mud, and they do self clean very well. Not the best choice for hard packed surfaces, but 80% of the terrain I traverse is red Georgia clay, nasty stuff when wet.
Just be cautious about going oversize on a smaller engine, they rob a lot of torque and you'll be more likely to bog down with a grippy tire like this.
