These revisions have been adopted by the Tire and Rim Asso- 

 ciation and are in accordance with present practice. 



There was considerable discussion in the Standards Committee 

 meeting relative to establishing in the standard a single set of 

 rim and felloe-band dimensions to provide for interchangeability 

 of the 36 by 6, 38 by 7 and 40 by 8-inch pneumatic tire on a 

 single rim, and also the interchangeability of this application on 

 the wheel. This matter is to receive early consideration by the 

 Tire and Rim Division and representatives of other automotive 

 industries who are interested in this matter.
