Series of motorcycle tyres
1997-10 - 14 Issued on April 1, 1998 Implementation National Technical Supervision Bureau CB/T2983-1997 This standard is based on the standards IS4291:1985 Trailer tyres and wheel tyre codes - Part 1: Wheel series - Part 1: Wheel size designation IS0422100 Trailer tyres and wheel tyre codes - Part 2: Tire rating IS05751-1994 Motorcycle tyres and wheel tyres (metric series) - Part 1: Design criteria 3.1505751-2.2004 Wheel tyres (metric series) - Part 2: Wheel size designation Part 2: Tire size and load capacity 3, ISO575]3:1591 motorcycle wheel inspection and rims (metric system 5) - Part 3: Alignment of wheels 3, 1559U51.19824 lightweight heavy-duty motorcycle tires and rims - Part 1: Tires 3.1S () C54-1994 motorcycle tires and rims (diameter code 4 to 12) small wheel diameter - Part 1: Tires 2 can be repaired according to JISD42U3-1991 motorcycle tires list $ standard focus, the type of technical requirements. The equivalent of the IS0 standard is adopted. The main differences between this standard and the energy version standard are as follows. This standard combines the use condition characteristics with the tread type of the metric series motorcycle tires as an appendix. The specifications of the metric series motorcycle tires are supplemented according to the IS standard, and the provisions of the nominal width of the wheel series of 50.55.60.70 are added, making the specification series more complete, which is conducive to the integration with the upper and lower countries and promoting the development of my country's light truck and road truck industry.
This standard will replace GB29B3S1 from the time of entry into force. This standard compiles the use condition characteristics into Appendix A (standard reference), and the tread type of the metric series motorcycle tires into Appendix B (reference reference) This standard was proposed by the Ministry of Chemical Industry of the People's Republic of China. This standard was organized by the National Technical Committee for Standardization of Tires and Wheels: Drafting unit of this standard: Beidao Tongdong Rubber! Drafting persons of this standard: Su Hongpin. Pan Juze, Chen Qiufa, Xiao Chuhua, Yang Haiying: This standard was first issued in March 1962 and revised for the first time in October 1951. This standard is interpreted by the National Technical Committee for Standardization of Motorcycle and Bicycle Tires. 1 Scope

Nominal width
This series of tires is named by the ratio of its section height H to section width S multiplied by 1, which is the tyre width ratio. There should be a grade mark. The standard series specifies tyres with a nominal height-to-width ratio of 50, 55, 60.70.8C.91.100, and uses the relatively variable type and 5-angle bottom type tyres as the standard! 3.3 Lightweight wheel
