Foreword
This Standard is not equivalent to ETRTO-2007 “The European Tyre and Rim Technical
Organisation Standards Manual” (English Edition).
This Standard replaces GB/T 2978-1997 "Series of Passenger Car Tyres".
Compared with GB/T 2978-1997, this Standard has the main changes as follows.
— The expression "speed step " in GB/T 2978-1997 is changed to "speed symbol"
(Chapters 3, 4 and 5 of the 1997 edition; Chapters 4 and 5, Tables 1~19 and Appendix
B of this edition; )
— The expression "standard rim" is changed to ""measuring rim" (Tables 2~9 of the 1997
edition; Tables 1~15 of this edition);
— Radial tyre series 40, 35, 30, and 25 as well as Type T temporary-use spare tyre for
passenger cars are added in this Standard (Tables 9~13 of this edition);
— The inflation pressure table for enhanced radial tyres for passenger cars is added in this
Standard (Table 17 of this edition);
— The basic inflation pressures for enhanced tyres of each series are adjusted in this
Standard (Tables 2~9 of the 1997 edition; Tables 1~14 of this edition);
— Requirements for enhanced radial tyres for passenger cars and the designation "ZR" are
added in this Standard (Chapter 4 of this edition);
— The requirements for maximum pressure of use for radial tyres for passenger cars are
added in this Standard (5.6 of this edition);
— Recommendatory requirements for the use of inflating valves of radial tyres for
passenger cars are added in this Standard (Chapter 6 of this edition);
— Requirements for the corresponding relations between speeds and basic inflation
pressures of tyres with speed over 160 km/h under the maximum load are added in this
Standard (refer to Table 18);
— Requirements for the load variation for tyres with speed over 210 km/h are added in
this Standard (Table 19 of this edition); and
— Requirements for the deviation of section width and overall diameter of passenger car
tyres are adjusted in this Standard (Table 2 of the 1997 edition; Table 1 of this edition).
Appendixes A and B of this Standard are normative.
This Standard was proposed by China Petroleum and Chemical Industry Association.
This Standard shall be under the jurisdiction of National Technical Committee 19 on Tyres
and Rims of Standardization Administration of China (SAC/TC 19).

Size Designation, Dimensions, Inflation Pressure
and Load Capacity for Passenger Car Tyres
1 Scope
This Standard specifies the terms and definitions of passenger car tyres, the size designation
methods, and the dimensions, inflation pressures and loads corresponding to size designation
etc.
This Standard is applicable to new pneumatic tyres of passenger cars.
2 Normative References
The following documents contain provisions which, through reference in this Standard,
constitute provisions of this Standard. For dated reference, subsequent amendments
(excluding corrections) or revisions of these publications do not apply. However, parties
coming to agreements based on this Standard are encouraged to investigate the possibility of
applying the most recent editions of the standards. For undated references, the latest edition of
the normative document referred to applies.

3 Terms and Definitions
For the purposes of this Standard, the terms and definitions established in GB/T 6326 apply.
4 Size Designation Method
The tyres for passenger cars are defined and represented with their size designations and
directions for use.
Example 1.
measuring rim, new tyre dimensions, maximum dimensions in service, static loaded radius,
rolling radius and approved rims.
5.2 As for standard and enhanced radial tyre for passenger cars with speed of 160 km/h or
below, the corresponding relations between their load capacities and different inflation
pressures shall meet the requirements specified in Tables 16 and 17 respectively.
5.4 The corresponding relations between load indexes and load capacities shall meet the
requirements specified in Appendix A.
5.5 The corresponding relations between speed symbols and maximum speeds shall meet
the requirements specified in Appendix B.
5.6 The "inflation pressure" mentioned in this Standard refers only to the inflation pressure
of tyres under cold state at normal temperature, excluding the pressure in...
