The 420/85R30 (16.9R30) agricultural tyre category in Kenya includes heavy-duty tractor tyres designed for strong traction, stability, and consistent performance during demanding farming operations. This size is commonly used on medium to large tractors because it provides reliable grip, efficient power transfer, and excellent balance across different soil conditions such as cultivated land, loose soil, and firm terrain.

Agricultural tyres in the 420/85R30 (16.9R30) size are manufactured using reinforced radial or bias construction with durable rubber compounds engineered for agricultural use. They are built to perform consistently under heavy workloads, extended operating hours, and varying field conditions. Their deep lug tread patterns enhance traction, reduce wheel slip, and improve fuel efficiency by transferring engine power efficiently to the ground.

Farmers and agricultural contractors prefer this tyre size because it supports stable load handling, enhances tractor control, and delivers long service life even during peak farming seasons. Strong sidewalls resist cuts, impacts, and abrasions caused by stones, stubble, and rough terrain. Whether used for ploughing, planting, hauling, or tillage work, 420/85R30 (16.9R30) agricultural tyres provide the durability and performance required for professional farm operations.
