Shinko 540 Series Knobby Soft terrain
The Shinko 540 rear tyre looks like the old Yokohama Dirt Digger tyre from the 80,s. It has well spaced tall knobs and a paddle like knob pattern. These are a great performance soft terrain tyres but will work OK in most conditions. The tyre compound is hard and reasonably durable if you stay out of the rocks. These should be more popular.
