British Standard List of Rubber Tyres for British Standard Rims.' 



THE URGENT NEED for reducing the great number of sizes of 

 rubber tyres in use on automobiles having been recognized 

 by the British Rubber Tyre Manufacturers' Association, a 

 scheme for that purpose was suggested by them and submitted 

 to the British Engineering Standards Association for considera- 

 tion and eventual issue as British Standards. 



The scheme was considered and certain modifications were 

 made to the proposals and these are embodied in the present re- 

 port and have been accepted by the British Rubber Tyre Manu- 

 facturers' Association. 



In consultation with the American Society of Automotive 

 Engineers (one of the sponsor bodies of the American Engineer- 

 ing Standards Committee) the S.A.E. Standard Tyre sizes, both 

 pneumatic and solid, have been included in the list, a further step 

 thus being taken in the direction of Anglo-American co-operation. 



As the standard list of rubber tyres is urgently required by the 

 automobile industry, the present memorandum is issued as an 

 interim measure pending the revision of the British standard re- 

 ports aflfected. 



The dimensions of the tyres given in this memorandum are 

 nominal, whilst those of the rims are actual. The sizes of the 

 tyres are the usual trade description as applied to tyres designed 

 to fit the respective rims. Full size dimensioned drawings of the 

 rim sections are in course of preparation. 



It is to be understood that the British Engineering Standards 

 Association in no case guarantees that the goods bearing its 

 mark are made to the standard sections and specifications issued 

 by it. The mark is to be regarded as no more than prima facie 

 evidence adduced by the manufacturer that the goods are made 

 in accordance with the standard sections issued by the British 

 Engineering Standards Association.

The above range includes all sizes regarded as necessary for the 

 equipment of all types of cycles — juveniles, standard roadsters, 

 and carriers — excepting only racing machines. It is not proposed 

 to standardize either tyres or rims of special racing types.

In view of the unsatisfactory range of light car tyre and rim

 sections of tyre for each rim is adopted.
