Hybrid tires, also known as Rugged Terrain (R/T) or Hybrid Terrain tires, have larger tread voids than all-terrain tires, providing better off-road traction without the road noise of a Mud Terrain tread pattern. In response to the desires of many truck, Jeep and off-road enthusiasts, a few different tire manufacturers decided to produce hybrid tires such as the Toyo Open Country R/T and the Nitto Ridge Grappler which have a quiet and comfortable ride while also maintaining aggressive styling.
