Show CARE OF TIKES VERY MBTANT Pressures Maintained Must Conform to Loads Carried. In the course of tire development, tire experiments have proven . that among the most important factors in the proper treatment of tires is the .adjustment of the ratio between the air pressure of the tire and the load to he carried. Engineers have made long and comprehensive studies of the proper amount of nir to be used with certain loads. The life of the tires is actually lengthened and the service given is improved if these observations observa-tions of the engineers are regarded. Overloading Is Fault. Overloading is a common fault and the disregard for careful adjustment of air pressure in the tires caused all sorts of tire troubles, which are not attributable to the construction of the tire but to their use. The engineers and chemists are nt work constantly improving the materials from which tires are made and the machinery for their production but all of the principles prin-ciples back of the construction of the tire are based on maintaining an air pressure commensurate with the load to be carried and the design of the ' tire. If the loads are increased the nir pressure must be made to conform )therwise tere is an insullicient ' amount of air in the tires for the load carried and this produces unnatural Inflation which causes an unnatural wear cn the tires, if the load is too light for the air pressure carried there Is not the resiliency or buoyancy to the tires that there should be. This is particularly true of balloon tires in which the variation of the air pressure Is a matter to be most carefully at tended. Ergine Irr.proves. Tires like the motor of the automobile automo-bile respond to good treatment and the good motorist is the one who will heed the best advice as to the care of the engine. lie will us? his automobile for years and the engine will actually improve in bis hands while In the hands of the poor motorist the engine will develop a multitude of troubles So it is with tires. Proper care actually actual-ly will give maximum mileage. Considering Con-sidering that the tires carry tiie load of the car and the contents, as well as protecting the whole mechanism of the car against the road blows, there are no more important elements in the operation of the car than proper tire adjustment, inflation and load. |
