THE CARE OF TYRES.

PRECAUT10NS TO TAKE. Consider the pneumatic tyre from the human standpoint. Air is the "soul" of the tyro, and its vitaJity is dependent upon the pressure. Any tyre that is under-inflated or overinflated cannot b© expected to give the same servic© or "life" as one that is properly inflated according to the schedule laid down by its manufacturers. Tyres that are underinflated. are starved, and tyres that are over-inflated are overfed. pneumatic tyres need only one diet. and that is air and all users should see that their tyres are properly fed, No satisfactory substitute for air has b,een discovered sinoe tlie pneumatic tyre was invented. There is no better cushion than air, because air will "flow" with the shap© of the tyre in motion, and the pressure will remain equal at all points at all times. The inner tube is merely an air container, and any special tvpe of tube that is thiclor at any one point will hinder the oo'mfortable running of the car. Test your air pa'essure regularly and at frequent intervals, and see that even pressure is maintained. No one can accurately test the air pressure of any tyro by mere guess work; this can only he done by using a proper tyre-gauge. The air pressure in rear tyres must be equal, the same with the pressure in front tyres, although the pressure in front tyres can often he slightly lower than the rear. Rear tyres with unequal pressure will cause disoomfort to passengers, and give the car a tendeney to skid in one direction. Flront tyres with unequal pressure will interfere with tlie proper steering of the car, In testing the air pressure in your tyres, he sure to see that your valve is not leaking. If it is fit a new "valve inside," and see that your dust cap is properly screwed down. No taxi or car can run properly on deflated tyres, and trouble' caused by negligence always occurs at the most inopportune moment, causing extreme annoyance to everyone. With proper and daily attention to your tyres, every driver should he practically, immune from tyro trouble. Tyre cost is one of the most iinportant items in the upkeep of any car or taxi, and a very great saving in the tyre bill can he effected by proper oaro. In inflating your tyres to the schedule recommended by tlie 'tyrie manufacturers rememher that tiie schedule for tlhe variouis sizes and types was finally agreed upon only after years of actual experienca under all sorts and conditions of road and driving conditions. S'ee that your spare is always inflarted to the maximnm pressure you require for your back wheels. If a change is reqnired for the rear, then your spare is ready to' fit immediateJy, but if you are using a slightly lower inflation on front wheels and a change of front tyre is necessary, i ust deflate the spare tio the required pressure to ensure even running of the car. Far too little attention is paid by car owners to their tyres, and if tyres were only treated as they should be, car owners would save huiidreds of tliousands of pouuds the world over.
