Show Changing Tires on Car Will Increase Mileage Changing truck or passenger car tires at regular Intervals ,'roiu one wheel to another will Increuse the mileage of a set of tires to a greater degree than the average owner realizes. real-izes. Tire companies havu done a great deal of experimental 'vork along these lines dining the pat.f few years "Engineers," says a r, esentutive of u tire concern, "have ade exhaustive exhaus-tive tests relative to cooiporatlve wear on tires lu vurious positions. They have learned that those on the right wheels. are subjected to greattr wear than those on tbe left, and those on the rear wheels to more than those on the front. "Thus It readily can be seen that occasional changes will effect more equal distribution of wear with a consequent con-sequent increase in mileage. "Itecofds have been kept at a certain cer-tain factory on a large number of tires, which have run in the aggregate aggre-gate more than 8,000,000 miles. Some of these tires have been run continuously continu-ously in the same positions. The records rec-ords show that the average tire on the left front wheel will give nearly twice as much mileage as the oue on the right rear wheel. "The mileage In the various positions, posi-tions, therefore, will be approximately the following proportions: To one mile of service on the right rear wheel tires will average 11-10 miles on the left rear, 1V4 miles on the right front and li miles on the left front. In other words, the average tire that would run 6,000 miles on the right rear wheel would run about 7,000 miles on the left rear, 9.000 on the right front and 11,000 on the left front wheel." |
