Show FLEET OF TRUCKS HIE TESTING OUT TIRES i U. S. Company Is Staging Efficiency Runs Over 310-Mile 310-Mile Course. A rigorous test of automobile truck efficiency ef-ficiency in long hauls is being made by the United States Tire company, which is using its test fleet of trucks for transporting trans-porting from its Detroit factory to its Indianapolis plant large quantities of machinery, removal of which to Indianapolis Indianap-olis has been made necessary by factory economies, according to Sid Theobald, local lo-cal branch manager. The two factories are 310 miles apart and the fleet of three trucks has already made several trips in each direction. All of the trucks are equipped with Targe pneumatic tires and the records which have been kept demonstrate that the com-t com-t pany's claims that pneumatic tires make greater speed possible, while saving not less than S3 1-3 per cent in gasoline and great wear and tear on the engines, as compared with trucks equipped with solid tires, are not exaggerated. On one of the recent trips from Detroit De-troit to Indianapolis the trucks covered the distance in 17 hours actual running time, an average of IS. 9 miles an hour, and tha return trip was made at the rate of 17 miles an hour. One of the trucks is a one and one-half one-half -ton car, which already has covered 40,000 miles. The rear tires on this truck are 3Sx7 in size, and before they gave the slightest indication of trouble had achieved a mileage of more than 9-U00 miles each. Each of these rear tires carries car-ries a weight of 3327 pounds when the truck is loaded. The two other machines are a one-ton and a three and one-half-ton. Full loads are carried in both directions, direc-tions, machinery being carried on the trip south and inner tubes on the return. There is no delay at either end, as the loads are planjjed in advance. |
