Depending on the climate you live in, season changes can be slight or they can be extreme. Some areas of the United States have very temperate climates with a rainy season and a hot season. Others have a short, hot summer followed by a long, very cold and snowy winter. The climate you live in determines your relation to all-season tires.
全季轮胎是指在整体条件下发挥最佳功能的轮胎。与冬季轮胎或专用的夏季轮胎相比，全季轮胎的处理能力比其他轮胎更好。
全季轮胎如何设计？
当轮胎制造商设计全季轮胎时，他们考虑的主要因素是：
- 胎面磨损的寿命
- Ability to channel water away in wet conditions
- 道路噪音
- 舒适的骑行
其他因素（例如寒冷的天气表现）也有一个因素，但程度较小。
如果您曾经看过轮胎广告或小册子，您会注意到许多人对有用生活有评级（例如，60,000英里）。胎面磨损的寿命是根据不同类型车辆的正常工作条件下的平均使用来估算的。它主要考虑轮胎的成分和密度。它具有保持牵引力的能力，同时最大程度地减少磨损量。较硬的橡胶化合物将具有更长的胎面寿命，但会更容易失去牵引力，而较软的橡胶化合物在不同的条件下会更好地吸引牵引力，但更容易磨损。
轮胎驱散水的能力可防止一种称为水流的疾病。水力平球是指轮胎的接触贴片无法足够快地在道路上切入水以获得牵引力，并且基本上骑在水面的顶部。轮胎制造商设计其胎面块，以漏水，从胎面的中间和向外漏水。切入胎面块的通道和线称为sipes。这些饮食散布并抓住路面。
A tire’s tread pattern also plays a factor in the amount of noise transmitted into the vehicle’s cabin. Tire designs incorporate alternating or staggered tread blocks to minimize the droning noise from contact with the road. Road noise is mostly an issue at highway speeds, and poorly designed tires are noticeably louder than higher quality tires.
The rubber used in an all-season tire is firm, and can create a harsh ride that transmits the vibration from bumps into the passenger compartment. To improve the comfort of ride, tire manufacturers strategically design the sidewall to be softer and allow more cushion over bumps.
Are all-season tires really good for all seasons?
全季轮胎是围绕驾驶条件的最佳选择，但是它们在44度以上的条件下表现最好。在该温度以下，轮胎中的橡胶化合物变得更加困难，这增加了停止距离并使牵引力更大的可能性更大。
如果您只偶尔在寒冷和下雪的情况下开车，all-season tires may be the best choice for you. If you live and drive in a climate that experiences several months of cold weather and snow, consider a separate set of winter or snow tires for temperatures below 44 degrees. They will improve traction in cold weather and slippery conditions.
