PROPER INFLATION OF TIERS.

"The first and last rulo for the motorist who would get the longest mileage from his tires, is to keep them properly inflated, says the manager of an American rubber company. "There are definite rules covering the proper inflation of tires. When tires are under-inflated and driven in this condition, instead of the resilient action and even distribution of the load, they are cramped between the road and the rim. Any one at all familiar with the construction of tires knows that they are built up of a carcase composed of the finest cotton fibre, impregnated and coated with rubber, to which a heavy troad is vulcanised. They are built so they give resiliency when fully inflated. But when they are run almost flat there is a decided breaking strain thrown upon the fabric. It has a similar effect when the tires are in play to constantly bending wire back and forth in one spot. The wire will break, and likewise the fabric composing the foundation of the tire is destroyed and the tire is worthless. Overinflation is another evil. In the first place, overinflated tires are subjected to undue strain. Then they have not the easy riding qualities in this condition. They are almost liko riding on solid tires."
