Kelly-Springfield Tires Now Sold On New Adjustment Basis Hereafter when adjustments are necessary they will be made on the following basis: Plain tread, 5,000 miles; Kant-Slip tread, 6,000 miles. In Ford sizes, plain tread, 6,000 miles; Kant-Slip tread, 7,500 miles. The word "adjustment," however, rarely figures in Kelly-Springfield speech or correspondence. In 1914 the total adjustments on Kelly-Springfield Tires for the whole United States were less than one per cent of sales. You get your tire service in uninterrupted mileage-not in adjustments. That's because Kelly-Springfield tires are made slowly and carefully by hand from the kind of real rubber that gives real mileage.
