'ITT 15 LA GRANIJK EVENING UHSKKVER 1 Extra Motor Power with - General Cords Explained Coasting and Running Tests Show Amazing Difference Between Tires H K'tt f i 91 (St ' 5 Pi The marked effect different makni of tire have on motor power waa ihowa in lieiwrml' recent announcn niraU o( coasting and running twit. To understand the reaann for tho" extra motor power demonstrated with the fieiwral Cord it must fir-it be understood that all mnkes of tires absorb a certain amount of motor power. It is internal friction in tirei that ca lines power 1. This varies tremendously according to ttm amount of internal friction in each. This Internal friction in tires uses up motor power in the Bnme way that friction in the working parts of mnchincrj acts as ft drag apiin.it power. Trictioii is overcome by hi brie lion. To prevent friction between metal parts a film of oil is used. In tho fume mnnuer, ruMier of the Hurst grade ami in generous quan tity U uned in the General Cord to kwp the cotton plica separated and rnch cord insulated. Thus, by a proooss equivalent to lubrication, (Jpneral ltas obtained rentor freedom from internal fric tion, and this is the reanon for the extra motor power with the General Cord in comparison with other makes of tires. Longer Mileage and Low Pressure Due to Less , Internal Friction The extra motor power with the General Cord has on oven bigger meaning than the gnsoline saving ,and the longer life of your motor, for that lAiite special feature of con struction that accounts for the extra motor power aUo explains the longer tire mileage General's greater free dom from internal friction. Internal friction is the greatest . known destroyer of tire. Friction always menus wear. . .And tin) tiro with the least internal friction Is naturally the tire that shows the lowest wear, provided this advan tage is gained, as It is in tho Gen eral Cord, without reduction in the number and weight of plies essential to proper construction. Jt was General' mastery of in ternal fricjion that enabled it to produce, Ave years 'ago, the first low pressure tire ever placed on the mnrket, Just as today it his enabled Gen eral to produce the successful fl ply In Moon cord, to replace 4-ply bal loons on all except the smaller cars coinhining nil balloon advantages with the right atrength for tho load, as well as reducing balloon punduru rink to a minimum. Tub lucneiiful urn of low pasture depends upon a ronst ruction t lint is aide to withstand the henting-up and wearing effect of the increased bending and straining under low pressure. This shows why General's leader ship in low-prepauro tires, not only In balloon sire, but. in nil Jugular ires, pnea hand in-hnnd with Gen. eral'i greater freedom from Internal friction. It. shows also why Oenernl has never els ssi lied its Hegulnr size cords as "high-pressure' tires. t General Shows How Internal Friction Is Overcome The process of complete insulation in the General Cord goes beyond the commonly used method of passing cord fabric through a thin solution of gum dissolved in benzol. Gen eral's special process, which can only bo accomplished by putting the cord plies through largo steel cal ender rollers, gives every ply a heavy coating of fluent rubber, uni formly thick, forced liHween the cords so that each cord is completely surrounded end no two cords can louelh Other important factors in Gencrnl's friction-eliminating proc ess lire the special weave nnd high est quality of combed cotton, as well as the development of new principles of tire construction jthroughouU General Cord Users Enjoyed Low Pres sure Before Balloons General Cord users did not have to wait f'r balloons in order to en joy low air pressure. With cxjM'ricnee, in low-pressure construction dating back beyond tint n( any other niamilolurtr, lovr pressure in Kegulnr size General Cords had become a well-known fea ture long before the advent of bal loon tires. ' In fact, the history of General's development of nw pressure is the siory of tho evolution-of the balloon tire. , This is tho background that ex plains General's singular ' success with low pressure, first with Heg ulnr size cords nnd thea with 4-ply end C ply balloons. a en wn a i. atNKRAt 1r k of t ho Urt d i nfl Ti rc; Storo ? Q-PIy Ball oon General's 4-ply Balloon is the practical equipment for the smaller cars. For the heavier cars the 6-ply has greater thick ness to carry the load and still it allows the full flexing action over obstructions. At the same time, it reduces Balloon puncture risk to a minimum. And General's 6-ply Balloon consumes no more power than the average 4-ply bal loon because General's greater freedom from internal friction al ways means power and gasoline saving.
