The Nokian Ground Kare is a new tyre that meets the new demands faced by the increased use of wheeled excavators in challenging applications.
Nokian Tyres is aiming to offer a full range of tyres with the emphasis on different surfaces and stability demands. The recent trends in earthmoving include big, multi-function machines with heavy work attachments requiring bigger load-bearing capacity from a tyre. Another change is towards faster and longer road transports, which means the tyres must offer good road handling properties and withstand the wear and tear of paved roads. The third trend is the need to be gentle to the soil and enable accurate working – essential features when excavating city parks and private yards. Nokian Ground Kare tyre was designed from ground up with these requirements in mind.
Excavating sites are different. For applications demanding absolutely the best stability, the block-patterned Nokian Armor Gard 2 tyres can be used in dual configuration. For very soft surfaces, the wide, lug-patterned Nokian Excavator tyre is often preferred for its grip. Striking a good compromise between the two, the all-new block-patterned Nokian Ground Kare tyre has a good grip on soft surfaces, low surface pressure for little impact on soil as well as excellent stability and on-road properties. To bring the important stability for safe and accurate excavating work, the tyres have a special rubber compound that absorbs swings and shocks as well as a very sturdy carcass that allows high operating pressure.
All-round ruggedness is also important on rocky excavation sites. Nokian Ground Kare tyre has steel belts against cuts and cracks. It has a load-bearing capacity of up to 7,500 kg (16,500 lb) per tyre.
The Nokian Ground Kare tyre sizes are selected with both wheeled excavators and backhoe loaders in mind. Nokian Ground Kare tyres will be available from June 2019 onwards in sizes 650/45-22.5 for excavators and 620/60B34 for backhoe loaders. The special railroad variant 620/60B34 Nokian Ground Kare semi-slick tyre will be available from December 2019. Source
