How Many Tires Does Your Car Need To Go 10,000 Miles? The above question is of direct interest to you. It makes no difference whether you are concerned about motoring economy for personal reasons, or simply as a principle of national conservation. The average car (on the right) either heavy,or rigidly-built,or both - to go 10,000 miles, needs an extra set of tires, or eight tires in all. The Franklin Car (on the left) to go the same distance-and further -needs only the four tires on the car, or half as many as the other. There could be no clearer illustration of the timely economy of the Franklin Car; nor a more direct in dictment of unnecessary motor car weight. For it is excess weight that prevents the average heavy and rigid car from equaling the publicly-known Franklin tire-mileage. The action of the weight of an automobile on the tires is similar to a hammer blow -and the heavier the hammer the harder and more destructive the blow. Heavy weight pounds out tires prematurely. And the heavy car owner, accustomed to paying for tire-mileage he doesn't get, accepts this as a matter of course-until he meets a Franklin owner. For Franklin owners get a consistent delivery of 10,000 miles or more to the set of tires. The reason lies in Scientific Light Weight and Flexible Construction. The Franklin weighs 2445 pounds-the right weight for a full-size five passenger car. It also carries the minimum unsprung weight weight below the springs, that contributes to the pound and shock tires must meet. Franklin Flexible Construction-full elliptic springs, instead of the usual compromise type; chassis frame of tough, resilient ash instead of unyielding steel-is still another reason why tires on the Franklin get every opportunity to deliver the full mileage that is in them. This flexible construction reduces road shocks on the tires. There are no torque bars or strut rods to cause the rigidity that leaves tires unprotected. These are facts of Franklin Construction that affect the whole performance of the car. Because of Scientific Light Weight, because of Flexible Construction, the Franklin is not only economical in tires, but it also gives a day-by-day delivery to its owners of 20 miles to the gallon of gasoline-instead of 10. Think of these things-and decide whether any car that combines fineness with motoring economy such as this, is not worth your immediate inspection; es pecially in these days when waste in motoring is not going to be considered any more legitimate than waste in anything else.
