EFFECT OF OIL ON TYRES
HAS DETERIORATING EFFECT. In a general sense oil is harmful to tyres, and the importance of not allowing them to stand in pools of oil or grease in garages is now generally recognised. A tyre standing in oil will absorb it, and then a slow but sure deteriorating effect takes place. If' a strip of vulcanised rubber is placed in paraffin, in the course of time it will swell and lose its characteristic toughness. Engine oils and lubricants iD general come from the same base as paraffin, and . their action is the same, though much slower. The fact that after a time oil leaves a permanent atain on rubber - proves the oil is actually absorbed, which da rather contrary to what would be expected from a sup-' posedly impermeable substance. On this reasoning any part of a tyre whieh has absorbed oil will be Ibsb able to resist wear and impact by cutting objects than the rest of the tyre.
