The demands placed upon tractor tyres are evolving. In addition to field work, the volume of transport tasks and time spent on the road has increased significantly in recent years. This trend presents a challenge for tyre designers as field and road applications are very different by nature. Nokian Tyres approached this challenge with a new kind of hybrid pattern technology that aims to offer the best of both worlds, combining a field-ready lug pattern with a block pattern to improve on-road properties. But does it work in practice? The Faculty of Agriculture, Department of Agricultural Engineering at Germany’s Kiel University put the Nokian Ground King tyre through its paces to find out.
