MEETINGS 



A MEETING of the Rubber Reclaimers' Division of the Asso- 

 ciation was held in New York City on November 9, at 

 which prevailing trade conditions were discussed in a 

 general way, as a result of which a joint conference of scrap 

 rubber dealers and reclaimers was held in New York on 

 November 19. 



A meeting of the Hard Rubber Division was held in New 

 York City on the 24th instant. 



The next meeting of the Board of Directors is scheduled for 

 November 30 at New York City. 



The November regular meeting of the Mechanical Goods 

 Executive Committee was held in New York on Tuesday, 

 November 23. 



The November regular meeting of the Executive Committee 

 of the Tire Manufacturers' Division, scheduled for Wednesday, 

 November 17, was omitted. The next meeting of this Committee 

 will be the December regular meeting on December 15. 



GENERAL 



The Association has undertaken the gathering of statistics on 

 a monthly basis from individual tire manufacturers who are 

 members of the Tire Manufacturers Division, relative to the in- 

 ventory, production and shipments of pneumatic and solid tires 

 and inner tubes and the amount of cotton fabric and crude rubber 

 consumed in that production, the Association in turn to furnish 

 the totals compiled from the individual returns to each member 

 participating in the arrangement. This work is progressing as 

 rapidly as possible, and it is expected that, early in December, 

 a report of total inventory, production and shipments as of 

 November 30 will be available. 



ANNUAL MEETING AND BANQUET 



The regular annual meeting of The Rubber Association will 

 be held at the Waldorf-Astoria Hotel, New York City, on the 

 afternoon of Monday, January 10, 1921. On the evening of 

 that day, the twenty-tirst annual dinner of the .'\ssociation will 

 be held in the grand ball-room at the Waldorf-Astoria. Informa- 

 tion will soon be transmitted to members of the Association con- 

 cerning the price of the dinner tickets, the names of the 

 speakers, etc. 



RECOMMENDED SPECIFICATIONS FOR PNEUMATIC CORD TIRES 



The following is a reproduction of a resolution adopted by a 

 majority vote of the Executive Committee of the Tire Manu- 

 facturers' Division on July 29, 1920, concerning minimum and 

 maximum cross section widths of pneumatic cord tires, with an 

 amplification of the resolution in the form of a detailed list of 

 minimum and maximum cross section widths of tires, rim sizes 

 and widths, and standard S. A. E. inflation pressures : 



RESOLUTION 



In view of the well-recognized economic advantages which 

 have been derived by the public and by the individual tire manu- 

 facturers as a result of the adoption by those manufacturers of 

 the standardization program recommended by the War Service 

 Committee, which program restricted the number of tire sizes, and 

 with a view to retaining and extending these advantages by 

 standardizing, as far as practicable, the actual sizes of tires made 

 in accordance with that program ; 



Now Therefore, it is resolved that the Executive Committee of 

 the Tire Manufacturers' Division recommends to the individual 

 tire manufacturers w'ho are members of that division that the 

 actual cross-sectional width of pneumatic cord tires when inflated 

 in accordance with the S. A. E. standards be not less than the 

 nominal width marked thereon or greater than ten per cent in 

 excess of such nominal width ; it being understood, however, that 

 the nominal width of the so-called 5-inch tire shall, in accordance 

 with custom, be considered as 5% inches.

The cross-section dimensions referred to are those of the finished 

 tires and not the tire molds. 



The cross-section dimensions referred to are to be determined by 

 measuring new. unused tires not sooner than a half hour and not 

 later than one hour after mounting on the rim and inflating to the 

 -5. A. E. standard pressure. 



In determining the cross-section dimensions each tire is to be 

 mounted on a wide standard rim of the same nominal size as the 

 S'/^' J^c c t'"^^!"'"" °f fhe •^l " 4 CI., the 33 x 5 S. S., and the 

 ,^1^1 ■,^- . "^" ^'■'^ '° ^^ measured, respectively, on the 30 x S'A 

 CI the 32 X 4/. S. S., and the 34 x 4'/, S. S. rim. 



Ihe only sizes to be affected by the recommended cross-section 

 widths m the table are those perpetuated sizes which are now or 

 which may be recognized as such by The Rubber Association of 



"37u-*'j "'^•' f°'' original equipment by vehicle manufacturers, 

 and this does not affect those other sizes which are to be produced 

 to provide for replacements. 



GUARANTY AGAINST PRICE DECLINE 



New York, November 13, 1920. 

 fo the wcmbc-s of the Tire Manufacturers' Division and the 

 Footwear Diinsion: 



There is enclosed a copy of the brief filed by counsel for this 

 Association with the Federal Trade Commission in connection 

 with Its inquiry into the practice by manufacturers of guarantee- 

 ing to the distributer or dealer protection against loss in the 

 event of a decline in prices. 



Previous communications from this office have informed you 

 concernmg t',c part taken by this Association in the investigation 

 by the Commission, beginning with the development of informa- 

 tion in detail concerning the exact practices and views of tire 

 and rubber footwear manufacturers with respect to the subject 

 and the presentation „f an expression of opinion from the tire 

 and rubber footwear industry to the Commission by a committee 

 representing this Association at the "Trade Practice Submittal" 

 or informal hearing, held by the Commission in Washington on 

 October 5. 



It is not expected that the Commission will issue any formal 

 announcement as a result of its inquiry and the representations 

 made to it by the various interested industries and it is thought 

 that it will simply use the information obtained in disposing 

 of such specific complaints as may come before it. ' 



.\t the close of the informal hearing on October 5 the Com- 

 mission announced that it would accept briefs from those who 

 might wish to file them and counsel for this .Association con- 

 cluded that it would be advisable for us to take that action, and 

 the enclosed copy is sent you as a matter of information.
