SINCE ONLY A FEW WELL CONDUCTED FIELD TESTS HAVE BEEN MADE TO DETERMINE THE RELATIVE TIRE WEAR ON THE VARIOUS TYPES OF SURFACES, THIS INVESTIGATION WAS INSTIGATED PRIMARILY TO OBTAIN INFORMATION ON THE METHODS OF CONDUCTING SUCH TESTS. IN ORDER THAT A REASONABLY WIDE DIVERGENCE IN RESULTS MIGHT SECURED, THE TESTS WERE RUN ON TWO TYPES OF SURFACES WHICH IT WAS FELT WOULD GIVE SUCH RESULTS. PORTLAND CEMENT CONCRETE AND WHAT IS KNOWN AS A NON-SKID TYPE OF ASPHALTIC CONCRETE WERE SELECTED. CONCLUSIONS AND RECOMMENDATIONS ARE MADE ON THE TYPE OF VEHICLE, THE RELATIVE VALUE OF MEASUREMENTS ON FRONT AND REAR TIRES, THE DESIGN OF TIRE BEST ADAPTED TO MEASUREMENT, THE LENGTH AND OTHER DETAILS OF THE TEST ROAD NECESSARY TO SECURE ACCURATE RESULTS, THE EFFECT OF TEMPERATURE ON INFLATION PRESSURES, THE RELATIVE VALUE OF MEASUREMENTS BY DEPTH OF WEAR AND BY LOSS IN WEIGHT, AND THE EQUIPMENT AND PERSONNEL. /AUTHOR/
