up railroad traffic, so the defective tion.
 Years ago when the motor truck as vehicle of transportation was still in its infancy, Firestone built the first solid truck tire.
 The most careful thought of the country's best tire engineers was put into the design and construction of this tire, and it became standard the country over.
 Since the advent of that first truck tire, Firestone has kept pace with every step forward of the motor truck industry, building a tire for every road, load and type of service.
 Great Responsibility
 As transportation demands grew and as the scope of the motor truck developed, greater responsibilities were placed on rubber tired transport vehicles. and with the demand of heavy hauling came a demand for varied types of tires to meet varied conditions of service.
 In every case Firestone supplied the answer.
 The giant tire with the deep grooved tread is today recognized as the most efficient heavy service tire in existence. It was given to trans portation by Firestone. Over three and a half years ago the first Fire stone Giant was placed on the market For over year previously many Firestone Giants had been used on test trucks and in all kinds of ser vice throughout the country under the careful surveillance of Firestone engineers. Like all Firestone pro- 1r sl service before it was offered to truck operators That is a Firestone char acteristic. Firestone never places an untried product on the market. Firestone Giants
 Success of the Firestone Giant tire among truck operators was instant aneous and while some experts were saying It couldn't be done,' Fire stone Giants were yielding mileage in a measure never before thought pos sible.
 The Firestone organization has grown so accustomed to doing the best thing, and doing it first, in the | truck tire field, that the successful | development of the Giant tire was | taken as a matter of course; also, has been taken as a matter of course its remarkable efficiency in all kinds oi | heavy hauling.
 For over three years and half now Firestone Giants have demonstrated their worth in every kind of heavy | hauling service. From the lumber camps of Oregon and Washington tC | the forests of Maine in every sectior of this country and abroad, Fire stone Giant tires have built them. selves an enviable prestige. The bif massive tires with their deep groove. have attracted spread atten tion, as they rolled over the paved streets of the city and rough road. of the country. Today, as three anC half years ago, there is but on' real proven Giant truck tire.
 The knottiest problems of transpor tation are being solved with Fire. stone Giant tires. In their fourtl year of service. war demands mak their leadership unusually conspic uous.
 Over sixty-five per cent of all tn trucks in the country are equippe' with Firestone Solid tires. For ovel fifteen years this Firestone leader ship has existed.
 Other tires will continue to imitat the Firestone design, but they canno initiate Firestone quality. The opera tor who wants the big mileage, tn efficiency and the satisfaction c Giant tire performance should loo for and demand the Firestone trade mark.
 Whatever imitation is made c Firestone design nothing can sup plant the Firestone name and tn quality it stands for-that is tn truck operators guarantee of Mos Miles per Dollar"
