PLANS TO SOLVE TRE PROBLENS Company Establishes Tech- nical Service Bureau to Aid Truck Owners. With a'view to enabling truck own- ers to secure greater efficiency from thelr trucks and to lessen their tire bills_a technical service bureau was cstablished a few months as0 by the Un..:d" States Tire ¢ompar ‘olve any .tire problems su {ruch own s In anncu. i the burc.u h: com the fear that nearly of the country were Op.ra.ng _on tires nol best suited to-them. The avidity with which ruck owners In all parts of the country have availed themselves of the offe: of this free tire advice has demonstrated that nearly every owner has some apecial problem which only a skilled engineer is qualified to pass on. Any truck owner anywhere may address the| technical s-rvice bureau, United States Tire Compgny, 1790 Broadway, New _York city, and get the advice of “fts group of engineers, Specimen Questions Asked. Following are specimen questions and answers recently acted cn by the bureau: uery from a New Orl hard- ware denler: We are not pleased with the service that tires are giv.ng on our three-quarter-ton trucks. We are nsing 35x5 cord tires on both .front and rear and fird that we do vot wear off the treads on the rear wheels but invariably have trouble with terrible snags and peeling off of rubber from 1he side walls of the rear casings. The front casings give good service. Reply: The five-inch tires you are using are passenger-car tires, which re not constructed with the purpose of distaining the side sway result- ing Wom use on rear wheels of trucks that are fitted with overhanging bodies. To withstand this sway pneu- matic tires for trucks need to be built especially heavy in ghe ‘tread and side wall. . § Needs Heavier Conmstruction. The fact that the tires on yout truck are giving. way in the side- walls Is an indication that this truck needs a more heavily constructed tirs. To solve your problem we can offer two recommendations: One is that you use on the rear wheels 86x5 pneumatic truck tires, which will fit Your present rims, or.'that you cut down the rear wheels to accommo- —_— e Henry % Ford plan s ours Pay a.man well and get better work out of him.

The five-inch truck tire with its heavier construction will give much better service than passenger tires of the same size, although there will overload of 375 pounds per tire. The six-inch tire, however, has a carrylng capacity of 2,200 pounds and would more than pay for itself in service under the conditions under which you operate. Rear Tires ‘Not Holding Up. From a firm of general contractors in Kentucky: We operate a truck rated two to three tons hauling two cublc yards of gravel weighing 5400 pounds a distance-of ten miles. Part of the road Is rutted macadam with many small pot holes. and the rest is well packed gravel road and good dirt road. We have 36x6 pneumatics gn the front wheels and 38x7 pneu- ‘matics on the rear. We are having no trouble with front tires, but the rear ones are nat holding up. Are we using the correct sizes omr this truck, and which type would you recommend for rear wheels, pneu- matics or solids? Reply: The weight carried on each of your rear tires is 4,025 pounds. and on each of the front tires 1725 pounds. The maximum carrying capacity of six-inch pneumatic truck tires is 2.200 , pounds. seven-inch pneumatics 3,000 pounds. eight-inch pneumatics 4,000 pounds and seven- inch solids 4.500 pounds. It appears that the sevem-inch pneumatic tires now on you | speed. wheels are overloaded approximately 1.000 pounds each. We believe that this is the main cause fo: the failure of the seven-inch pneumatics to stand up. To adequately carry the load vou should use eight-inch pneu- maties. Taking into consideration the road conditions, which appear to be hard roads for the full trucking distance, we do not think that pneumatics are as economical as solids for your rear wheels. It would appear that solids would get plenty of traction under the road conditions. If this is true, the remaining advantages which a pneumatic tire would have for rear wheels would be speed and cushion- ing. Part of the roads over which you operate are rough, therefore speed is not possible over a con- siderable part of the distance. The effect of pneumatic tires for cushion- ing the rear end is not as important as for cushioning the front end as far as truck upkeep is concerned, especially when operating at low Our recommendations would be, therefore, that you either change your seven-inch rear pneumatics to eight- inch pneumatics on eight-inch rims, or that you change the rear equip- ment from pneumatics to solids if the truck is not so old that it would not pay to change. A seven-inch solid tire of the mono-twin type is best suited to your road and load con- | ditions. With pneumatics on the front wheels and mono-twins on the rear wheels you should be able to obtain t satisfactory tire results. sity. WATCH YOUR STEP HERE. IT IS ONE OF THE WORST CORNERS IN THE CITY.

A car produces one cublc foot: or more of carbon monoxide per minute, and Prof. iienderson calculates that in a small closed garage (10 by 10 by 20 feet) the car, when warming up, contaminates the air to a deadly con- centration within three or four min- utes. “Many people lose their lives every winter by running their engine with the garage doors and windows clos- ed,” he poins out. “The only safe way is to open the garage doors be- fore starting the engine, or to slip piece of hose over the exhaust and deliver the gas out of doors. “These Investigations were carrled out for the New York and New Jer- sey tunnel commission which is con- structing a vehicular tunnel under the Hudson river.

W. Haggard, working with me, has shown that these symptoms are not due to the gasoline vapor, but to the carbon monoxide gas which re sults when the Tilollne vapor is e: ploded in the cylinders of an engine. “Carbon monoxide combines with the red coloring matter of the blood, and this prevents the blood from car- ing an adequate amount of oxygen from the lungs to the brain, and other parts of the body. But we find that soon after the affected person comes into fresh air again, the carbon mo- noxide begins to leave the blood.

A cold winter is the forecast, but it's a cheerful one for the owners of SyracO. No more “north pole” garages homes and stores, because a heating system is too costly to install. SyracO burns either hard or soft coal. Its pat- ented, trouble-proof temperature control regulates the consumption of coal and eliminates the necessity of constant at- tention.
