专家提醒，在北方的司机朋友冬天最好换上雪地胎。与普通轮胎相比，雪地胎与路面的摩擦力更强，提高了冰雪路面的通过性 和安全性。温度越低的时候，普通轮胎会越硬，而且胎纹宽大，在雪地上附着力小；雪地轮胎胎纹深且细小，与地面的附着力大。 吉林大学白求恩第三医院主任医师 罗民：在温度骤降的时候，第一，外出尽量戴口罩，防止冷空气侵入到呼吸道；第二，尽量 保护好我们的颈部，防止冷空气对我们的皮肤造成过度温度刺激；另外，还有尽量要保护好我们的前胸后背，就是属于神经系统敏 感部位。这些部位（受到气温骤降刺激）容易诱发心脑血管疾病。 央视网消息：低温雨雪冰冻天气来袭，户外出行时，我们既要防范路面湿滑带来的行车风险，又要警惕严寒刺激诱发的心脑血 管疾病。寒冷天气下，我们该如何做好防护、平安出行呢？ 北京警察学院教授 柳实：冬季昼短夜长，所以要打开日间行车灯，甚至要打开前后照灯，也就是我们俗话说的近光灯。冰雪路 面的摩擦系数下降，所以我们的车速也相应应当下降。在没有出现轮胎打滑和方向失控，平稳制动是最好的制动方式，做到轻踩慢 抬，打方向的时候也要做到柔缓。点刹车是当我们轮胎打滑、方向失灵，这种危险情况发生的时候，一种行之有效的方法。 ...

冬季雨雪天气下 路面积雪结冰易导致车辆打滑 车辆也"怕冷" 部件低温易"罢工" 普通四季胎在7℃以下会硬化 抓地能力下降 低温还会导致胎压降低 制动稳定性变差 冬季气温低 传统燃油车的 机油、变速箱油黏稠 发动机皮带、橡胶油封硬化 行驶时熄火重启难度大 容易导致车辆停滞 诱发追尾、剐蹭等事故 电动车续航 可能衰减20%~30% 开暖风则会进一步消耗电量 若遇到交通拥堵 冬季出行时 则需要长时间等待 可能出现电量耗尽的情况 雪花+反光双重干扰 当心视线受阻 降雪时飞舞的雪花 会阻碍驾驶人视线 而强光在积雪反射下 易导致驾驶人目眩 减弱驾驶人对交通状况的观察能力 构成安全隐患 给车子"做个检查" 湿滑脚垫"卡踏板" 脚下细节别忽视 雪天上车时 鞋子带入的冰雪会浸湿脚垫 湿滑脚垫易在刹车和 油门踏板下滑动移位 甚至卡住踏板 导致车辆失控 @司机朋友们 雪天开车要牢记这些注意事项 做好行前准备 途中把控和停车收尾 安全应对冰雪天气 出发前花5分钟 出行前检查车辆灯光 刹车、雨刮器等部件是否正常工作 清除车身积雪时 可以用60℃以下温水或除雪铲 避免用开水和雨刮器除冰 若长时间在冰雪路面行驶 建议安装雪地胎、防滑链 提 ...

新华社太原12月2日电（记者许雄）随着气温降低，许多地方最低气温已经降至零摄氏度以下，雨雪天气和道路结冰给交通安全带来挑战。受访 人士提醒，无论是驾车、骑车还是步行，都可通过提高防范意识，减少交通和出行意外事故的发生。 看不见的冰才危险 山西高速交警三支队四大队大队长赵树玉表示，道路上不易察觉的暗冰是冬季交通事故的重要诱因之一。以冬季高速公路行车为例，降雪后即便 路面积雪已清理完毕，但护坡等处积雪融化，易在背阴路段、桥梁或隧道出入口形成暗冰，导致行驶中的车辆轮胎摩擦力骤减。如果此时速度过 高或操作不当，存在车辆失控风险。交警部门建议，冬季驾车行驶在高速公路或快速路上，可根据道路情况，合理控制车速。一旦发现车轮打 滑，千万不要紧张，在没有其他因素影响的情况下，可尝试保持正常驾驶节奏，切勿大幅增减速，也不要急打方向盘。如果车辆已经失控，在系 好安全带的前提下，驾驶员要抓紧方向盘，乘车人要双手护住头部，优先确保人员安全。 可按需使用雪地胎 对于有需求的地区，雪地胎也开始成为部分消费者的新选择。山西太原的贺先生曾使用过雪地胎。他表示，使用雪地胎后，虽然油耗会小幅上 升，但能明显感受到车辆抓地力增强。在有积雪的路面上， ...

Report Industry Investment Rating - RU and NR are rated neutral. BR is also rated neutral [4] Core Viewpoints - The demand for winter tires is concentrated, and the tire operating rate continues to rise. The inventory of natural rubber in China has decreased, with the cost - end support for natural rubber remaining strong, but the supply is expected to increase in the peak season. For butadiene rubber, the supply - side support remains, and the price is likely to rise but the high inventory may limit the rebound space [3][4] Summary by Directory 1.

Market Analysis - Natural Rubber: Rainfall in major domestic and overseas production areas is expected to decrease. Since early October, China's inventory has decreased due to the slowdown in arrivals and the increase in tire operating rates. The demand for winter tires in northern China has boosted the operating rate of steel tires. With less rain later, focus on the price trend of cup rubber in Thailand. The cost - end support for natural rubber remains strong, but the supply is expected to increase in the peak season [3] - Butadiene Rubber: Many butadiene rubber plants are under maintenance, and more plants have maintenance plans. The supply - side support remains. The demand for winter tires in northern China has boosted the operating rate of steel tires [3] 3. Strategy - RU and NR: Neutral. China's overall supply and demand may show a prosperous pattern. If the arrival volume rebounds, the depletion of social inventory will slow down or accumulate again. Currently, the valuations of RU and NR are low, and the price is expected to move within a range. Pay attention to reverse spread opportunities [4] - BR: Neutral. Supply and demand may improve. The price of upstream butadiene raw materials is expected to be stable, and the surrounding natural rubber price provides bottom support for butadiene rubber. The price of butadiene rubber is likely to rise, but the high inventory may limit the rebound space. Pay attention to positive spread opportunities between months [4]
