Excerpt from Report on British Standard Dimensions of Wheel Rims and Tyre Bands for Solid Rubber Tyres for Automobiles: Revised, September, 1917 In July, 1916, the Committee were asked by the Society of Motor Manufacturers and Traders Ltd. To standardise Solid Tyre Band Circumferences. The Committee agreed to undertake the work, and for this purpose some representatives of the Society's Solid Tyre Committee were nominated by the Society to confer with sub-committee H. As a preliminary to standardising the internal circumferences of the Solid Tyre Bands, it was found essential to reduce the manufacturing tolerances allowed on the circumferences of the Standard Wheel Rims so as to ensure a satisfactory metal to metal fit between the Wheels and Tyres. The sub-committee was consequently enlarged to include representatives of the Auto mobile Wheel Makers, and a representative of the Commercial Vehicle Committee of the Society of Motor Manufacturers and Traders Ltd. Having agreed on a reduction in the manufacturing tolerances to be allowed on the Standard wheel rim circumferences, some tentative tolerances for the internal circumferences of the tyre bands, based on a metal to metal fit between the tyre band and wheel rim, were drawn up and the proposed limits were submitted to a number of the leading wheel makers and tyre manufacturers in this country for criticism, and after due consideration of the replies received the limits given in the following Report were agreed to. It is confidently hoped that when these revised limits are worked to in practice the trouble that has been experienced through the want of fit between the wheel rims and tyres, often necessitating the use of loose packing pieces, will be eliminated and the use of raised flanges rendered entirely unnecessary.
