PROGRESS REPORT ON TIRE WEAR INVESTIGATION

RESEARCH IS SUMMARIZED ON A STUDY DEALING WITH THE WEAR OF BALLOON TIRES. THE EFFECT OF TEMPERATURE ON THE TREAD WEAR OF BALLON TIRES SEEMS TO BE SO GREAT THAT AN ATTEMPT WAS MADE TO REDUCE ALL TIRE WEAR INDICES TO THE SAME TEMPERATURE BASIS. THE GENERAL CONCLUSIONS ARE THAT: (1) BALLOON TIRES ARE LESS AFFECTED BY DIFFERENCES THAN ARE HIGH PRESSURE TIRES, (2) THE FIRM SURFACE ROADS SUCH AS BRICK, PORTLAND CEMENT CONCRETE, AND ASPHALTIC CONCRETE, HAVE NEARLY THE SAME EFFECT UPON TREAD WEAR OF BALLOON TIRES, (3) DIFFERENT TYPES OF SURFACE, SUCH AS SAND-CLAY, GRAVEL OF GLACIAL ORIGIN, AND PROBABLY EARTH, ALL DRY AND IN GOOD SURFACE CONDITION, CAUSE LESS TREAD WEAR ON BALLOON TIRES THAN DO THE FIRM SURFACE TYPES, AND (4) FRONT TIRE TREAD WEAR IS GREATER THAN REAR TIRE TREAD WEAR ON FIRM SURFACE ROADS AND IS LESS THAN REAR TIRE TREAD WEAR ON LOOSE SURFACE ROADS MADE UP OF SAND OR GRAVEL WITH SMOOTH ROUNDED PARTICLES.
