PROGRESS IN TIRE MAKING. 



WIv decline to record a prophecy as to whether auto- 

 mobiles will ever be run very generally without 

 rubber tires. Bui it is a safe assertion that, without 

 elastic rims for wheels, the automobile as we now know 

 it would never have been developed. Progress in auto- 

 mobile buildiiiK— as relates to .size, the speed attained, and 

 the s.ifety of automobiling— h:is been made only .so fast 

 as tlie riil)ljer manufacturer has succeeded in producing 

 tires capable of withstanding the increasingly heavy 

 .strains placed u])oii them. We believe that the rubber 

 men have more than kept pace with the car constructors 

 in their .share iu the evolution of the automobile. 



Ill the first recorded automobile race, no competing 

 l)uilder was willing to have his car equipped with rub- 

 ber. But a rubber manufacturer who was determined to 

 have elastic tires tested built a car himself for which his 

 factory supplied the tires. No less than 26 tires were 

 burst in running that car 621 miles, and the result dis- 

 couraged the use of rubber for a considerable time. But 

 the automobiles of that period were all un.satisfactory, 

 for reasons wliich disappeared only when, through the 

 incessant efforts of the rubber men, resilient tires were 

 produced that could be depended on. 



Now that the automobiles in use are numbered by the 

 hundred thousand, who sees one without rubber tires? 

 Thev are used as a matter of course, bought as an every 

 day commodity, without a further guarantee than ap- 

 plies to the sale of goods generally. Tire punctures 

 happen every day, of course, but considering the great 

 number in use, the percentage is surprisingly small. 

 And by no means all the accidents in motoring are due 

 to tires. A contestant in a recent great automobile meet 

 in luirope, returning from the course with honors, 

 ditched his machine iu trying to avoid running down a 

 drunken peasant's cart, and the automobile was rendered 

 useless. But there is no record that tlie tires w'ere dam- 

 aged. 



Incidents can be multiplied indefinitely to show that 

 pneumatic tires withstand hard treatment and accidents 

 quite as well, if not better, than the remainder of the 

 vehicle. A tire goes bounding over a stone in the road, 

 unharmed, 1)ut if a crankshaft strikes it, it may be bent 

 and rendered useless. The rubber is elastic ; the steel 

 isn't. As far as strength is concerned, the tire maker 

 has only to put in the proper materials, in connection 

 with good workmanship, and the .same applies to dura- 

 l.)ility. 



Cood roads are desirable for automobiling, but not so 

 much for rubber tires as for the re.st of the machine ; in 

 fact, the great merit of the rubber equipment is that it 

 supplies a good road wherever it is carried, and without 

 which, in very many places, the automobile would be 

 unavailable. The best rubber tires made yet may not 

 be perfect ; the maximum severity of requirement on 

 the part of the motorists has not been reached. Even
