'DOC GATES' TALKS
 TIRE CONSERVATION

Secretary McAdoo in his speech. here m Phoenix. said in part; half-sole brooches and half-sole shoes, are badges of honor. l wear them myself and am glad to recommend them. like 10 think, that am releasing leather for soldiers feet and clothing for sol dier's body.
 The natural inference would be. ap- ply the same idea to your tires and have them half soled By doing so, you are helping conserve the rubber for govern ment use in tires and hundreds of other necessary articles.
 Although the automobile is more or less a necessity. yet it's manufacture has been considerably curtailed and it's use somewhat limited by no Sunday driving east of the Mississippi. In this section. less drastic steps have been taken by closing all oil and gas stations on Sunday except one for emergency purposes. later ruling is reported, in closing supply stations at 6 p. m. These measures are. as everyone understands. for the purpose of conserving material and the gasoline supply. If these meas ures of strict economy are good and necessary. surely conservation of your tires ought Co he in keeping with the Win the War Spirit
 There are a few pointers of the many that might help local motorists to not only do their bit' but more, cut down their tire expense and thus have more money to help the big fourth Liberty bond drive to a 100 per cent finish.
 Keep your tires up to full inflation A tire in fairly good shape should be inflated on an average of 20 pounds per square inch of tire diameter. Example, S-inch tire, 50 pounds, 315 inch, 70 pounds, etc. Do not depend on others io inflate your tires, or if you do get ont of the car and see that it is done properly and tested with a standard gauge. Tires should be tested. every morning if possible or sometime during tho day at least This will detect slow leaks which are so destructive to tire fife. Examine your casing from time to time for cuts. nails and small particles of glass. Tread cuts, if deep enough, soon cause loose tread, fabric separa- ton and rot. Watch your front wheels as well as tires. More tires are ruined by front wheels being out of alignment than probably any other cause and you have no adjustment coming in such cases. Applying brakes suddenly is hard on tires. especially If the wheels skid. Letting in the clutch suddenly also causes undue wear. Standing tires in oil or oil dripping from leaky bearings un to the tires. causes the rubber to dcterioratel. Careless driving. hitting unnecessary bumps, rocks. etc. soon knocks the life out of the best tire
 Another, and possibly one of the greatest contributing causes to tire trouble. low mileage and discomfort, is poor tube. Under this classification would be included. cheap new tubes good standard tubes carried around in differently under the seat, second hand tubes that have been frequently vul- eanzied or dry patched. Leaky valves arc also contributing causes to low mileage.
 The answer to tube troubles and how
 O greatly increase tire mileage is; very time you buy a new tire, buy a new tube. buy new good tube. Tube: wear out quicker. carrying them around m the car than in the tire.
 Our last thought is. to remember that poor or cheap tubes, wear out nor, tires than rough roads.
