Things Every Motorist
 Should Know
By R. C. SAUFLEY,

~ NE might almost say that tires ' have life, just as plants, trees or
 animals have life; they must be cared for just as such things that real ly have life, must be cared for. The time and trouble expended in caring for your tires will repay you twice over. You can get the maximum mile age and life from your tires by being careful and observing the few pointers given here.
 Imitation is the most important point in getting full life from your tires. Lack of sufficient air causes more tire trouble than all other causes combined. The sidewalks of a tire are the thinnest part of pneumatic tire and it is here that most of the bending action takes place. If tire is run insufficiently inflated this kneading and bending is increased as the tire bends sharply at every revolution of the wheel and each time it strikes an obstruction. On the other hand, if the tire is properly inflated, it may hit the obstruction but bounds off without materially affecting the flexing mo- ton. In initiating your tires do not try to judge the proper imitation by kick ing with your foot or pressing with your hand but use a reliable tire gauge.
 Punctures
 If tire is punctured the car should be stopped immediately. Riding on a deflated tire will ruin the fabric and loosen the tread very quickly. Prob ably the defects caused by riding on a tire flat or under low pressure will not be noticed at once, but may re- suit in sudden blow out due to the inner weakening of the structure of the casing.
 Stone Bruises
 If tire hits an obstruction, such as car tracks or a large stone, the inner fabric may be bruised and weakened or perhaps torn. The damage to the tire may not show at all on the out side, but after a time, sooner or later the chances are the casing will blow out prematurely. Small bruises often grow into serious injuries. Even the most careful driver can not avoid bruises altogether, but generally | speaking, properly inflated tires are l better able to resist the impact of a blow when the tire strikes an obstruc- | tion.
 Wheel Alignment
 Wheels out of true will grind the tread off tire in an unbelievably short time. I have seen a tire com pletely worn out within fifty miles or a wheel out of line a little over three inches. When wheels are not in proper alignment they run at an angle to the direction in which the car is | travelling. This produces a severe l grinding between the tread and the road and wear the tread down at the | point of contact in a very short time To determine whether or not you wheels are out of line, the following is a good method
 Get a straight edge measure be. | tween the felloes of the wheel or the dogs of the rims on the wheels at the point directly in front of the from axle. Mark this distance carefully and measure in the same way across the wheels directly back of the front axle or opposite where the first mea- surements were taken. If any differ ence is found it should be corrected | immediately.
 Overlooking
 Excessive weight on a tire will breal down the fabric in the side walls. caus. ing the casing to give way. When thi. happens the tire generally is not ii for repairing.
 Damaged Tires
 Damaged tires should be taken to { competent repair man and repaired a once. A tire properly repaired vii last as well as if never damaged.
