Sledge Hammer Blows!, TMHE biggest hammer that ever a blacksmith swung does not deliver a blow as heavy as those your tires get hundreds of times in a few miles of travel. That cotton fabric and rub ber can stand up under such punish ment is remarkable when you think of it. A blacksmith will tell you that the temper of steel can be spoiled by too much heat. Little wonder then that even a few degrees too much in the vulcanizing pits will ruin a tire by carbonizing the cotton. This re sults in a tire that cannot stand the pounding 9 f daily service. By the exclusive Miller method of vulcanization all the essen tial oils and Wax are retained in the cotton fabric. The native toughness and resiliency of the rubber are kept intact. Both cotton and rubber are welded into a rugged mileage unit. GEARED-TO-THE-ROAD TIRES are never Spoiled in the making. They come to you brimful of mile muscle andl with 100o power to resist and endure. The blows of the road affect them almost as little as the hammer affects the anvil. Hundreds of thousands of motorists found Miller Tires to be faithful long-distance performers in 1916.
