| 中文摘要: |
| 通过减小BR用量以及改变炭黑品种和用量，改进半钢雪地轮胎胎面胶配方设计。改进后，胶料在保持良好物理性能的基础上，滞后损失增大，抗湿滑性能提高。成品轮胎试验表明，试验配方轮胎的耐久性能良好，高速和强度性能提高，冰雪路面上的制动距离缩短14%～35%。 |
| 英文摘要: |
| The tread formula of snow steel-belted tire was modified by reducing the BR proportion in NR/BR blend and changing the type and addition level of carbon black.The results showed that the hysteresis of tread compound increased and the wet traction improved by the modification without any adverse effect on physical properties.The test results of finished tire showed that the endurance of test tire was similar to that of production tire，but the speed performance and strength improved，and the braking distance on ice/snow road reduced by 14%～35%. |
