Goodrich Outlines Abuse And Care Of
 Solid Truck Tires

Proper care of solid truck tires means more to the truck owner than increased tire mileage and lessened tire expense. It means greater eff ciency on the part of the truck, fewer mechanical breakdowns and less time in waiting for repairs.
 The importance of eliminating tire abuses is so generally recognized at preSens that many truck owners go to great pains to point out to the drivers the damaging effect of various abuses and show how they can be avoided. Some even offer bonuses and show how they can be avoided. Some even offer bonuses to the drivers attaining the greatest tire mileage.
 The following summary of tire abuses. prepared by the B. F. Goodrich Rubber company, shows the things that a truck driver should avoid to get maximum tire service. Although brief, it covers the ground thoroughly. It may well serve as the drivers pri- mary text book on tire care.
 Overloading-Of all possible abuses to solid motor truck tires, overlooking is the most disastrous. Tires should be large enough to take care of the greatest load the truck carries. not the average load.
 In loading the truck. care should he taken to distribute the weight carefully so that crushing leverage, which is ruinous to the tires, will not be eX- erted
 Speeding-Heat destroys solid tires, just like it does pneuna1ics, taking the life out of the rubber. Heat is gen erated in the tires by pounding of the load and friction against the roadbed when a truck is driven at an excess speed even if the highway is smooth. Consequently the truck should be driven sanely to avoid permanent tire l injury.
 Cs,,fe fN.rfs f,1 sol; should not be neglected any more than cut in the tread of a pneumatic Cuts near the edge of the tire tend to en- | large. especially in a circumferential direction. If not properly trimmed. the i torn rubber of flag catches as the wheel revolves and the injury becomes worse. Neglected cuts have often de veloped to such an extent that they l have caught in frogs in car tracks and torn off practically the whole 1 tread. To prevent the continuation of 1 a cut on the edge of a tire, bevel it of with a sharp knife.
 ! Skidding-Skidding or locking the i brakes and sliding the wheels causes serious damage both to the trucks mechanism and the treads of the tires Drivers should be taught that thei1 trucks will stop quicker if brakes are applied gradually and firmer than witt i a jerk.
 Improperly adjusted brakes vii i sometimes cause one wheel to lock resulting in section of the tire being ground or torn off.
 As soon as a truck starts to skid i should be steered. if possible, in tn, direction of the skid. Abrupt turning of corners has the same effect as skid
 ding, increasing the strain and wear or
 the tires.
 Car Track Abuse-Injuries resultin,
 from running solid tires in car track
 are serious and readily apparent. Tn

 major portion is carried upon the sec
 ton running on the car rail, with tn | result that it is quickly worn an, , broken away. The injury is not con , fined to one or two spots on the tire ! but extends around the entire circum
 ference. eventually leaving the tire re dueed by one-half to carry the ful
 load.
