Show WATER INJURY TO TIRES IS SMALL Running Through Stream Is Not Injurious. Now and then In the course of aa automobile trip a car bat to paas through a stream, and the qnestlon la sometimes discussed whether the action ac-tion of tb water Is harmful to the Urea. The tame question arises when the cur la out In a heavy rain. Such a wetting la practically nothing noth-ing at All olrhn. trtm A a m a irm - In,. Ing at all, either for damage or Improvement Im-provement At any rate, the effect on the tire la not harmful. Two chief constituent! of a tire are rubber and cotton, both vegetable substances, and at a rule water does not Injure vegetable vege-table mutter. At Illustrative of thlt point, there It the old but true story of the farmer who, when one of bis rubber boots fell Into a well, placed the other on a nhelf In a closet. Twelve years later when the well was cleaned the lost boot was found to be In excellent ex-cellent condition, but the boot on the shelf had fallen Into ruin. If running through a brook resulted In cooling tire the effect would be decidedly beneficial, but a quick dash through the water hat little effect on the heated air within the tire and consequently the temperature change In the tire after Its bath la negligible. Water Itself apparently doet no harm to tlret, but the combination of air and moisture commonly known at humidity It very destructive, especially especial-ly on the cotton In ordinary fabric tires. The moist air works In between the layers of the fabric and rots them out, sometimes even before the tires leave the dealer's storeroom. Cord tires stand humidity better. The harmful effect of moist air Is the chief reason why, when tires are stored, they thould be kept In a dry atmosphere. As sunlight Is also harm- ful, the storage place thould be darkened. |
