OPEN COUNTRY W/T - winter tyre off. Recommended for winter operation in the city. Three longitudinal grooves to boost water and snow pouring from the patch. Special silicone components in the bus attached bus softness at low temperatures(up to 23 degrees C), which reduces wear on tires and increases the lifetime of the wheel. Special additives in the rubber mixture remove water from the tread blocks, effectively sweeping tread on the water and snowy porridge.
