It follows that what really injures the canvas In pneumatic tires Is CONTINUED CON-TINUED dampness. If water Is allowed al-lowed to get Into cms which extend through the tread to the fabric, some such condition of continued dampness will be brought about, for once tho moisture enters a cut It has but little lit-tle chance to evaporate.
