Bought my 4runner with these tires on it already. E rated tire rode super stiff till I dropped the psi to 30-33. Tread blocks are big and grab everything. They haul 20ft boats quite easily. For an all-terrain, it's the 31" tire that doesn't want to stop when you hit the dirt uphill. I read tons of bad reviews on these and wanted to replace them immediately, but drove them till I could find the right tire. Time has proven the tread life is great on these, they wear like rocks. I have rolled through logging fields, no punctures. Traction in snow is fantastic, I can go most places offroad in 2hi. Their biggest weakness is significant squirm in the rain. I take corners slowly anyway in my heavy vehicle, but these RTS like to slip and slide. When it's raining and the roads are curvy, I go five mph under the limit.
