WEAR ON TIRES

"i. .SOME COMMON FAULTS ,i ' i Many tire troubles arise as the direct result of ''mechanical faults in tho rvehiele. Briefly, any condition which creates, a tendency to move tho wheels in aiiy direction other than that of their.rotation, comes within the scope of misalignment, and is detrimental to tires.. In 'a general way.tho fault first evidences itself, in; irregular or. abnormally rapid, tread' wear, but many motorists of experience will bo sensitive to some i eccentricity in tho steering., Prompt investigation may bring tho* fault to Hght'-bcfbrc serious results ensue... De-.: fects of this nature usually demand the attention of a competent engineer, but will generally be found to bo one or another., of the following: Bent stub? axles,; b'ent-*steering tie-rod, looseness oi" play '.iii steering^ connections, unequal; set iit: springs resulting from malad: justmeiitjior. from a broken spring leaf,, bont t.orque':rod,. wheelout of round or loose ,; ; at, bearings. Occasionally the front :wheel tires will be observed to "have .'.worn..'completely; down on one, side, the. .other- .being almost, untouched. - . The explanation of this lies in the splay, of .the-wheels, .often adopted to promoto easy steering, and where this condition exists the tires should bo changed from side to sido periodically ito ensure uniform wear. A too fierce ; clutch, or ono that is carelessly operated, may produce effects similar to those of unduly harsh brake action by causing the rear wheels to accelerate more rapidly than tho tires can convey the - impulse to the vehicle. In this case, of course, the more effective the nonskid design of tho tread the less damage it sustains, but additional strains are imposed upon the casing, and the tire suffers accordingly.
