LIKE THE BODY IS THE AUTOMOBILE TYRE.

It Has Bones and Skin, But It Needs Only Air to Keep It In Good Health.

That there is a close analogy between an automobile tyre and the human body is the statement of one of the technical experts on the staff of the United States Tyre Company. The carcass of a tyre may be compared to the bones.; the tread and side walls to the skin, while inflation pressure is to a tyre what food is to the body. • * . * When you cut yourself you are careful to wash out the injury and to protect it from infection until it heals. A cut in a tyre should be just as carefully looked after because neglect will be followed by "infection" in the form of sand blisters, loading to separation and finally "death" in the form of a blow-out. * * « Breaks in the carcass of a tyre require the same attention as a broken bone. The breaks must be repaired and "splints," in the form of a sectional vulcanised inset, applied in order to reinforce the broken part.

If you did not continually furnish your body with food to replace that used up by the digestive processes you would s<K»n die. A tyre requires a certain inflation pressure to enable it to carry its load. "Digestion," in the form of a leaky valve, diffusion through the inner tube, etc., slowly uses up this pressure, and if it is not continually replaced the tyre soon breaks along the flexing lines and "dies" through a blow-out.
