Krawlers are worth the $$ in my opinion
They dont have a great sidewall either though but by far have the best traction. I was pretty dissapointed in iroks though. For a multi purpose DOT Approved tire i would run either Bfg Krawlers, Great traction but wear kinda fast, or creepy crawlers because they stick pretty well for a DOT tire and the sidewalls are tough as nails, but they run small so if your replacing 37" mtrs i would go with 38" creepys. And they are made for a 15" rim and lasted 2 years on a buddys truck who drove his on the street freqently. Or Bfg km2's work pretty well too. All 3 tires are some what pricey though.
