the tread suffers cut, so much of the protector is removed and sand. mud, water and other inimical agents are able to reach the carcass of the cas- ing instead of being fenced off by the resilient rubber outer covering. While the dirt and sand and mud work their wa along, separating the rubber from the fabric. the water rots the cotton and the result Is ruined cas- ing within measurable tfff1e.
 The owner who desires to reduce his tire expenditure to the reasonable minimum, will make a point of giving all his tires a weekly inspection. He will repair all cuts, even small ones, within a day or two of theiR appear ance. For small cuts, those up to half an inch say. a tread sfiller of some sort may be used. For the longer cuts. especially when the fab ric is laid bare. vulcanization is es- sential.
 Every cut in the tread should be thoroughly cleaned out before being repaired. A cloth soaked in gasoline may be used for wiping out the cut, then a bit of cloth on the end of a screwdriver may be used for remov- ing any dirt lurking inside Next . coat of cement should be applied to the sides and bottom of the cut After this has dried a second coat should be applied and when this is thoroughly dry. tire filler should be inserted. A piece of the filler may be
 worked into the cut with the blade of a knife, the mass being leveled off
 with the surface of the cut. If the tire has to be used immediately. a small piece of cloth or paper should
 be cemented over the filler so that
 it will not pick up dirt from the road. It Is now possible to get tire repair kits from various manufacturers. in cluded in which are tire ganEe. ce- ment patches. filler. inside and out side blowout boots. tale, etc Every car should carry one of these kits as regular equipment. Constant care is the price of tire efficiency
 In addition to underinflation, mis- alignment of wheels causes excessive tire wear When the wheels are not
 running true, a scraping motion Is set up, which quickly tears the tread and
 ruins the easing. The harsh applica- l ton of brakes is a potent source oi
 wear in the rear tires. Jamming or | the brakes locks the wheels and the
 tires are dragged over the surface o1 the road instead of rolling over it. Care should be taken to use enough l tale on the inner tube to keep it from I sticking to the casing but, too mucf

 It often happens that a hurriedl, inserted flap folds and extends under the bead. which, being strained causes the side wall to break, giving every appearance of a rim cut. 4 flap which is creased or folded in thu casing will result iE a pinched tube.
