6. Dimensions
No provisions were established for the dimensions of valve attaching portions. Such dimensions, however, must be determined in sufficient consideration of the matching with applicable valves, as the portions are very important. Concerning the above, JIS D 4207 (Tire Valves for Automobiles), JIS D 4208 (Tire Valve Stems for Grommets for Automobiles), JIS D 4210 (Tire Valve Nuts for Automobiles) and JIS D 4215 (Rims for Motorcycles and Scooters) are available.
6.3 Deflections
The measurement of deflections of light alloy wheels is desirable to be determined under the agreement between the persons concerned, in consideration of the attachment dimensions of the hubs, and on the basis of the measuring methods prescribed in JASO C 603
