SCOPE 适用围This Regulation covers new pneumatic tyres designed primarily, but not only, for vehicles in categories M 2 , M 3 , N and O 3 and O 4 . / However, it does not apply to tyre types identified by speed category symbols corresponding to speeds below 80 km/h. 本条例适用于主要为 M 2,M 3, N 和O 3以及O 4 车型设计，而不仅限于这些车型使用的新充气轮胎。但是，它不适用于由 80 公里以下时速对应的。2. DEFINITIONS 定义For the purposes of this Regulation: 实施本条例的目的：2.1. Type of pneumatic tyre means a category of pneumatic tyres which do not differ in such essential respects as: “ 充气轮胎类型 ” 是指在以下几个基本方面相同的充气轮胎类别：2.1.1. The manufacturer; 制造商；2.1.2. Tyre-size designation; 轮胎规格；2.1.3. Category of use; 使用类别；2.1.4. Structure (diagonal (bias-ply); radial); 结构( 斜交；子午线 ) ；2.1.5. Speed category; 速度级别；2.1.6. Load-capacity indices; and 负荷指数；与2.1.7. Cross-section; 断面；2.2 . Category of use: 使用类别：2.2.1. Normal tyre means a tyre intended for normal, everyday, on-road use; “ 普通胎 ” 是指为普通路面日常使用设计的轮胎；2.2.2. Snow tyre means a tyre whose tread pattern, tread compound or structure are primarily designed to achieve in snow conditions a performance better than that of a normal tyre with regard to its ability to initiate or maintain vehicle motion. “ 雪地胎 ” 是指胎面花纹、胎面胶或胎面结构专为雪地行驶设计的轮胎，在启动或保持车辆运行能力方面，它比普通轮胎的性能更为优越。2.2.3. Special use tyre means a tyre intended for mixed use both on- and off-road or for other special duty.These tyres are primarily designed to initiate and maintain the vehicle in motion in off-road conditions;这些轮胎的设计主要是启动和维持在越野条件下运动中的车辆， “ 特胎 ” 是指为路用和越野多用途使用或其他特殊用途设计的轮胎。2.2.3.1 porfessionail off-road tyre is a special use tyre primarily used for service in severe off-road conditions.( porfessionail越野轮胎是一种特殊的主要用于在越野条件下使用的轮胎。)2.3. Structure of a pneumatic tyre means the technical characteristics of the tyres carcass. A distinction is made between the following structures in particular: 充气轮胎的 “ 结构 ” 是指轮胎胎体的技术特征。尤其是对以下结构进行区分：2.3.1. Diagonal or bias-ply describes a pneumatic-tyre structure in which the ply cords extend to the beads and are laid at alternate angles substantially less than 90 to the centreline of the tread; “ 斜交 ” 是指胎体帘线延伸至胎圈，并以与胎面中心线呈小于 90 的错角排列的充气轮胎结构；2.3.2. Radial describes a pneumatic-tyre structure in which the ply cords extend to the beads and are laid substantially at 90 to the centreline of the tread, the carcass being stabilized by an essentially inextensible circumferential be
