LENGTHY consideration is given to tire overloading, with the understanding that overloading as referred to in tire failures is quite different from the application of the term overload to structural materials which collapse under a reasonably well-defined excess of load.
While this paper deals primarily with overloading, there are so many other aspects relating to the use of truck-bus tires affecting the industry that a discussion is included of various other phases of the tire business intended to be instructive along the line of longer life and greater freedom from trouble.
The increasing varieties of service in which motor-vehicles are being placed demand different types and characteristics of tires, which are outlined. Then there is a discussion of the relative merits of the balloon type versus high-pressure-type tires.
The choice of tires for new trucks and buses is covered in a practical way and also there is a section outlining the variations of the basis for determining loads and air-pressure recommendations.
For the truck operator's benefit, there is included a section as to what the operators should know and practice to get the most out of tires, discussing the importance of inflation, dual mating, wheel alignment, repairs and retreading on both tires and inner tubes.
