The compaction capacity rating of tires (further CC rating) is a numerical index expressing the risk of soft soil compaction by loaded wheels with tires and reflecting the tire parameters such as the size, load and inflation pressure. The compaction is defined in terms of soil dry bulk density. The CC rating is based on processed laboratory measurements of soil compaction by pressure plates and thus avoids dealing directly with complicated stress field in the ground. A tire itself is represented by a substituting plate of the same footprint area and mean contact pressure. CC rating compares the average soil compaction by an examined tire in layers between 20 and 50 cm under the ground surface with critical soil compaction. The paper informs about principals and use of the CC evaluation technique. The CC tire rating is apparently the only existing numerical assessment of the risk of soil compaction damage, which reflects tire design and loading state. In the mild climatic conditions and on loam soil, the compaction risk can be qualified as follows (CC rating/risk): 0 and less/no, tire soil-friendly; 50/small; 100/considerable; 150/great; 200/very great; above 200/extreme. The CC rating has the character of trademark meaning that it is attached to the defined soil type, soil status and described procedure. For tires operating in regions with distinctly different soil type, for instance high percentage of clay (sand), the CC rating would be respectively adjusted, in this case reduced (increased). The values of CC rating application have to be considered as preliminary as they are based on computed tire footprints. To issue exact CC ratings, it is necessary to use measured footprints, which can be produced on the laboratory stand by contract. The exact ratings will be regarded as confidential. The authors do not expect that tire manufacturers will be keen to publish the CC ratings of their products, because the rating may limit the range of loading conditions of any tire listed in a catalogue. The CC rating may be applied to a complete vehicle or machines; the product with lower total rating can be in general more expensive, however may improve the economy of operation and production.
