GB/T 2981-2014Technical specification of pneumatic tyres for industrial vehicles (English PDF)

Foreword

This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This Standard replaces GB/T 2981-2001 Technical specification of pneumatic tyres for industrial vehicles. Compared with GB/T 2981-2001, the main technical differences are as follows.

- adjusted the indicators of physical and mechanical properties of tyre; deleted the physical and mechanical properties of pad (3.2 of Edition 2001, 3.2 of this Edition);

- added the requirements for pad (4.5 of this Edition);

- added the requirements for defects that a variety of tires do not allow to have serious impact on the service life (4.4 of this Edition);
