Show HOW TO OBTAIN LARGE MILEAGE FROM TIRES about three out of every four tires that pass on to the crap heap are prematurely and needlessly worn out through says a fisk rubber company expert in an un der denn inflated condition the tire is more susceptible to cuts and bruises rim cuts and fabric blow cuts outs develop because of the tremendous number of different positions the tire assumes tend to create internal heat and destroy adhesive qualities of the rubberized fabric the motomu who is careful as to the pressure will surely surel ly obtain tire mileage at small cost at the best the tire is a container of ah air on which the car rolls the amount of air nce necessary essary to carry will depend absolutely upon the amount of work that is to be done and the load carried the motorist should determine the load for each tire and regulate his air air pressure so as to carry that load without injury to the tire to do this weigh front and rear of car separately and divide by two which will give the weight pa earned carried on each now that the weight of load as carried by each cach wheel is known determine the air pressure by using the factor given opposite tire lire size to divide the amount of the load the result being the pressure required 3 inch tire ire divide weight 0 of load by 8 3 10 4 1 12 1 11 5 1 54 is 18 example on a 4 inch tiro tire you find the load to be ibs lbs refer to above table and note that on a 4 inch tire 12 is the factor lbs 1 divided by 12 equals 60 therefore innate inflate the tire to 60 ibs lbs air pressure As the load carried by the front fr nt ti tres ties es is usually less than on the rear by using the method as suggested it will be determined that less air u sure is needed the ideal load for the best beat all around results under average conditions is as follows S 3 inch 1 ires ibs 3 4 4 73 W a am 4 eco ow 4 6 5 1210 5 1485 A load heavier than these figures my may be carried but the rebul resulting ting pressure necessary to get let good tire mileage is unusually very bard haw on ca the ca and its occupants to obtain best results weigh car as suggested divide any load by b figure given and inflate to that amount test air air pressure at least once a week |
