On a recent trip to Las Vegas, Sailun Tire got Tire Review behind the wheel of a Jeep Wrangler to put its rugged-terrain tires, the TerraMax RT, through their paces. On both the highway roads of Las Vegas and the tough, rocky terrain from Red Rock Canyon, I was able to see how these tires perform in various conditions. I took these TerraMax RTs through the wringer - including sharp turns on steep canyon cliffs, cage-rattling rocks, high-speed merging, you name it.
