Abstract:

From the experience to date it can be stated that the test equipment, particularly the single-wheel test carriage, has made it possible to conduct rapidly a large number of soil-tire tests under a broad variety of controlled conditions. Some special tests have shown that the single-wheel data can be related readily to the performance of an actual 4x4 vehicle. The results of these tests show that a tires performance varies in a regular and systematic way in response to the three primary independent variables of soil strength, tire load, and tire deflection. In a particular test condition, the amount that a tire sinks and slips is related to the other test variables. However, except in a very general sense of the word, it has not been possible to correlate the performance data for all tire sizes and shapes by means of a single general expression. Author
