Automotive Tyres, Tubes and Rims Sectional Committee, TED 7

FOREWORD

This Indian Standard (Part 3) (Second Revision) was adopted by the Bureau of Indian Standards, after thedraft finalized by the Automotive Tyres, Tubes and Rims Sectional Committee had been approved by theTransport Engineering Division Council.

This standard was first published in 1983 and revised in 1991. The second revision is being based on theexperience gained after publication of the standard and availability of new designs. This standard has beenrevised to keep pace with the latest technological advancement in the field of wheels/rims for commercialvehicles.

This standard aims at uniform rims profiles that will match the tyres in obtaining proper fitment. The sizes,designations and markings have also been standardized to facilitate uniform adoption during manufacture.

This standard is one of the parts pertaining to rims for various types of automotive vehicles. The other partsin this series are:

(Part 1) : 2009 Nomenclature, designation, marking and measurement (second revision)(Part 2) : 2009 Passenger car (second revision)(Part 4) : 2009 Scooter and scooter derivative rims (first revision)(Part 5) : 2009 Moped, motorcycle and motorcycle derivative rims (second revision)(Part 6) : 2009 Rims for agricultural tractors, tillers and implements (second revision)(Part 7) : 2009 Industrial truck rims (first revision)(Part 8) : 2009 Earthmoving machine rims (first revision)

These parts do not lay down methods of testing and performance requirements for wheels/rims pertaining tothe respective tyres of automotive vehicles but lay down only the profiles and other general requirements.For passenger car wheels and truck and bus wheels/rims reference may be made to the following standardsfor methods of testing performance requirements:

IS No. Title9436 : 1980 Performance requirements and method of tests for wheels for passenger cars9438 : 1980 Performance requirements and method of tests for wheels/rims for trucks and buses

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance withIS 2 : 1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retained inthe rounded off value should be the same as that of the specified value in this standard.

GENERAL REQUIREMENTSPART 3 COMMERCIAL VEHICLE RIMS

( Second Revision )

1 SCOPE

This standard (Part 3) covers contours and othergeneral requirements for commercial vehicle rims.

2 REFERENCE

IS 10694 (Part 1) : 2009 ‘Automotive vehicles — Rims —General requirements: Part 1 Nomenclature,designation, marking and measurement (secondrevision)’ is a necessary adjunct to this standard.

3 DIMENSIONS

Dimensions of contour for light and commercialvehicles shall be as given in Fig. 1 to Fig. 5.

3.1 Valve apertures for semi-drop centre, wide baseand flat base rims shall be as given in Fig. 21G and21H of IS 10694 (Part 1).

3.2 For valve hole aperture of other types, see A, B,C, D, E and F of Fig. 21 of IS 10694 (Part 1).

3.3 For details of diameter, circumference andmandrel dimensions, refer Fig. 22 to 24 and Tables 1to 4 of IS 10694 (Part 1).

4 DESIGNATION

The size designation of wheel/rims shall includefigures and alphabets representing the following inthe order given:

a) Nominal rim width code,b) Rim flange profile designation, andc) Nominal rim diameter code.

Alphabet signifies the tyre side profile of the rimflange. Usually the profile designation follows thenominal rim width code. It may, however, precede orinclude the nominal width code.

Example:

4.50 E × 16B 7.0 × 20B 6.5 × 20

5 GENERAL REQUIREMENTS

5.1 The rims shall have a smooth contour free fromsharp edges on the tyre side.

5.2 The valve hole slot edges on the rims shall befree from burrs.

5.3 Starting with the highest point of the flange ofwell base or drop centre rims, the shaping of theflange contour towards the outer part of the rim isleft to the manufacturers, but any increase in widthof the rim flanges above the minimum width shall belocated lower than the highest point of the flange inorder to facilitate tyre mounting.
