钢帘线结构市场趋势及贝卡尔特的新品开发
- Belts of Passenger Tires 乘用胎带束层
- Belts of Light / Small truck Tires 轻型/小型卡车胎带束层
- Belts of Medium/Heavy Truck Tires 中型/重型卡车胎带束层
- Carcasses of Truck Tires 卡车胎胎体
Why Radials ? 为何用子午胎?Endurance 耐久性
Radial tires run much cooler under all conditions (high speeds , high loads) and show higher pared to bias tires.
子午胎在所有的条件下(高速,重载)服役温度更低,因而较斜胶胎具有更好的耐久性
Why Radials ? 为何用子午胎? Fuel Economy 燃油经济性
Radial tires and especially steel reinforced radials have lower Rolling Resistance leading to better fuel aspect ratio helps further.
子午胎尤其是钢帘线增强的子午胎因其滚动阻力较小而具有较佳的燃油经济性。小的高宽比对此有进一步的贡献。

Why Radials? 为何用子午胎? Retreadibility 可翻性
Radial Truck and bus tires get ,in the average, more than one retreads in USA. As a result , 55-60% of all tires are retreaded ones. 在美均翻修一次以上。因而在所有正在使用的轮胎中大约有55-60%被翻修一次。
