PENNSYLVANIA -©I r "o Question: Do They Actually Prevent Skidding? Answer: For three years now we have sold these tires on our widely advertised guarantee that they will not skid on wet or greasy pavements, else returnable at full purchase price Never a challenge of this guaranteefrom a user. There's no limit to their skid-resistance-the heavier the slewing force, the stronger grows the multiple suction hold of the heavy-walled Vacuum Cups. The rolling tire lifts and releases the cups edgewise without drag on the forward speed. And what tires can match their service? Guaranteed for 4,500 actual miles-with many records of 12,000 to 15,000 on heavy cars and great excess mileage always the rule. Absolutely oilproof. PENNSYLVANIA RUBBER CO. Jeannette, Pa.
