Show II H PURPOSE OF AUTOMOBILE TIDE "The purposo of a tire is to pro iile j'! traction, to prevent noise, to cushion : -i tli car and occnptuits from road in- ; ! equalities, nna to prevent crvstnlliza-. ! .( tion of the delicate parts of the meeh- , I anism, bv eliminating jar and vibra-J i! tion,, fdye K. K. Kanty.er, local man- 'i ' npor. yir. Kautzer added: i' There has arisen a new need for f ' tires, due perhaps to tho tendenev to drivo car5 the voar round. With j the coining of fall and winter ' weather, with their dangerous street , i conditions, the dancer from skid ding is increased. So tho problem of safe traction has become upper most in the minds of motorists, and ,l has brought out much constructive thought along line of tiro design- Ij ing. " j Innumerable nonskids havo been 1 placed on tho market, somo good ; I and some bad. Somo had irregular lj projections which caused the eutiro ' weight of the car to center upon ' ) certain points of the fabric. , As a (' result, the fabric weakened5 pro- ' maturely at these points. Somo had harp projections which quickly tore, and showed wear after being i worn a short while Then these ji harp'cut crevices filled with dirt. These wore styled "mud slingers" because tho centrifugal action of the tire caused it to throw dirt. You probably have experienced such a ' tire yourself. ' Then, others increased tho vibra- , tion of tho tire by placing tho pro jections too far apart. To over-i over-i , c.omo this tho projections were brought close together, so close in fact that tho do?ircd traction became be-came uo moro certain than with a smooth trend. Consequently, no single factor in the tire industry has boon given so t much thought as the idea of safo traction. Wo. ourselves, hnvo tried out innumerable devices, aud found them wanting. 3ror years we . Hearchcd for a tire that would rpn-1 rpn-1 dcr motoring safo, and still give long mileage. |
