Tire Care Tips

Tire Features

In shopping for tires, following your vehicle manufacturer’s recommendations is the failsafe way to the select tires that are best suited for you. 了解轮胎的特性, 要考虑的主要特征包括:轮胎尺寸, tire class, and tread type.

Size -轮胎的尺寸由许多因素决定，包括截面宽度, aspect ratio, and wheel diameter. Abiding by manufacturer specifications will assure the best fit and performance for your vehicle.

Class – The class of tire you chose should be determined by the how you use your vehicle and where you use it. 在经历各种天气条件的地区, an all season tire is a great choice, 但如果你住在冰雪严重的地方, you will need a winter class. 如果你看重舒适性和响应性，一个旅行级轮胎将满足您的需求.

Tread -胎面类型应根据您所行驶的道路类型或地形选择. 胎面花纹包括多向花纹, asymmetric, directional, all-terrain, highway, and more, each offering distinct performance benefits.

Tire Maintenance

保护你的轮胎投资从适当的维护开始. 保养良好的轮胎不仅能延长磨损和胎面寿命, 它们大大提高了车辆的安全性.

• Tire Pressure -正确的胎压对可靠操作至关重要, effective traction, and optimal tire life. Properly inflated tires will assure that the vehicle’s weight is equally distributed, resulting in even wear. Factors such as temperature change and leaks can affect tire pressure so it is important to check it often.
• Tire Rotation -轮胎旋转是确保胎面均匀磨损的关键因素. 取决于车辆的类型和你具体的胎面磨损模式, 不同类型的轮转模式将是最有益的. Having your tires rotated by automotive professionals will provide this service as well as the opportunity to detect other issues before them become serious problems.
• Wheel Alignment – Problems resulting from improper wheel alignment include poor vehicle handling and steering, as well as uneven and rapid tread wear. Many factors can effect alignment, including a minor accident, which may not cause visible body damage. 定期检查你的路线可以防止一系列的问题.

Tires 101

Introduction

On the road, the safety of every driver and passenger depends greatly on the quality of the tires that carry them. Despite that fact, tires are likely something the average person does not give much thought to until they need to be repaired or replaced. 对于每一位车主来说，花一点时间了解一下轮胎是值得的. 虽然韦德1946官方的轮胎101节不会让你成为轮胎专家, it will provide you with a basic tire overview and get you a little better acquainted with your tires.

The technology behind the tires of today combines advances in engineering and chemistry, as well as a solid understanding of physics. The newest designs offer the best performance, ride comfort, fuel efficiency, safety, and reliability. 今天的轮胎也是为了满足特定的车辆需求而开发的, or to perform well in certain climates.

Tires are comprised of many different elements, which are assembled in a TBM, or Tire Building Machine. 组装后，轮胎被固化并完成精确的规格. The basic components of a tire include:

• Bead – the tire gets its strength from the bead, which is a loop of high-strength, rubber coated cable. This strength allows the tire to stay mounted on the wheel rim and enables it to withstand mounting machine pressure when rims are installed.
• Body Ply -轮胎由多层或多层织物组成, 哪些是橡胶涂层密封在空气中，促进轮胎元素粘合. 织物类型可能包括聚酯线和凯夫拉. 胎体的层数反映了它的强度.
• Belt Package – steel belted radial tires incorporate bands of steel, which reinforce the area under the tread. The benefits of steel belts include greater puncture resistance and better road surface contact.
• Sidewall – providing lateral stability, the tire sidewall protects the tire and gives it good resistance to abrasion and environmental factors. Sidewalls also provide a thick rubber area upon which raised identification letters and decorative features are molded.

Tire Specifications

如果你曾经洗过车或检查过胎压, 你可能已经注意到每个轮胎的侧面都有一个代码, which looks something like this: P205/55R16 89H. This seemingly random combination of letters and numbers can tell you a lot about your tires, if you know how to crack the secret code. Actually, 没有什么秘密——这个规范代码是, for the most part, universally the same for all tire manufactures. alpha数字系统显示轮胎类型及其性能特征.

P205/55R16 89H Type of Tire

The kind of tire and the use intended are indicated by the first letter in the code. Letter designations include P primarily for passenger vehicles, T for temporary spare, LT for light truck metric, C for commercial, and ST for special trailer service. 欧制轮胎不包括这个第一个字母描述符.

P205/55R16 89H Section Width

Before the slash mark, and following the first alpha character, 轮胎的截面宽度以毫米为单位列出. This is the widest point from sidewall-to-sidewall, so a larger number indicates a wider tire. In this case, the tire has a width of 205 millimeters.

P205/55R16 89H Aspect Ratio

Following the slash mark is the aspect ratio, which is described as a percentage and gives the height of the tire from the bead to the top of the tread. Here the number is 55, which means the tire height is 55% of the section width of 205 millimeters. The height of this tire would be 133.25 millimeters. A lower number indicates a lower tire profile

P215/70R16 100S Tire Construction

轮胎的结构由长宽比后面的字母表示. The most common designation is R, which stands for radial construction. 其他不太常见的现代乘用车结构类型可能包括 D for bias ply construction and B for belted tires.

P205/55R16 89H Wheel Diameter

The number following the construction code is the size of the wheel that the tire will fit in inches. The example tire would be designed to fit a 16-inch wheel. 现代汽车的轮胎尺寸通常从13英寸到18英寸不等, 但是定制包装车轮可以是22英寸甚至更大.

P205/55R16 89H Performance Index
轮胎的性能指标通常与车轮直径有关, 表示轮胎的载重和速度等级. In this case, the 89 load index represents 1,279 pounds (per tire), and the speed rating of H represents 130 mph. The speed rating tends to be more significant in countries with roadways that are not subject to speed limits.

Common Speed Ratings

Letter	Max. MPH
L	75
M	81
N	87
P	93
Q	99
R	106
S	112
T	118
U	124
H	130
V	149

Measuring Tread Depth

A Penny for Your Treads?

Sufficient tire tread depth is an essential factor in vehicle handling and traction. In fact, tire tread depth is so important, 美国法律要求轮胎有清晰可见的胎面磨损指示条. 然而，这些杠可能很难看到，直到胎面磨损良好. The easiest way to measure tire tread depth, and be assured of the safety of your tires, is with the tried and true penny test.

How to Take the Penny Tire Thread Test:

• 拿起一分钱，让上面出现“韦德1946官方信仰上帝”的字样. 把它放在轮胎凹槽的五个不同部分, taking note of the visibility of Lincoln’s head.
• 如果你能一直看到林肯的头顶, this means that the treads are excessively worn, 是时候去买一套新轮胎了.
• If the top of Lincoln’s head (to about the forehead hairline) is consistently covered throughout the tread grooves, 胎面状况良好，你的轮胎可能不需要更换.

监测胎面深度和磨损是汽车维修中极其重要的一步, 不仅要确保轮胎的胎面形状良好, 还要检查其他问题的症状，例如:

• 轮胎过度膨胀——胎面中心极度磨损
• 轮胎充气不足-轮胎肩过度磨损
• Poor wheel alignment – uneven tread wear

保护你的轮胎投资和保持安全的道路. 记住——省下的一分钱是检查胎面深度的好工具!

Types of Tires

In choosing tires, 重要的是要考虑高质量的品牌和坚实的价值等因素, 但它也是必不可少的选择正确的轮胎为您的车辆类型. It is also imperative that driving conditions be a major consideration in making a tire selection. Several types of tires are available to suit every kind of vehicle and all driving conditions.

All Season Tires

All season tires are a widely used and most popular variety of tire, carrying S and T speed rating. 轿车和小型货车通常标配全季轮胎. All season tires are developed to handle most conditions from dry pavement to wet weather and moderate snow. 全季轮胎的特点包括舒适和安静的驾驶, reliable handling, as well as long tread life. All season tires are a good choice for most drivers, except where winters are severe. 对于在大多数气候下的全年牵引力，全季轮胎是一个很好的选择.

Winter Tires

A tread with gripping edges for better handling on snow and ice distinguishes winter tires from all season tires. Often winter tires are developed with a softer rubber compound that remains flexible in temperatures of extreme cold. Winter tires are not the best performers for driving on cleared roads because they tend to not grip as well as all season tires and tend to wear more quickly. 冬季轮胎应该在极端寒冷的天气下使用. Winter tires should be used in sets of four for balanced handling and optimal grip for braking in snow and icy conditions.

Summer Tires

Drivers looking for the all-around best performing tires in mild climates and seasons will find summer tires offer a performance level above all season tires. Summer tires, as the name implies, 完全不适合在冰雪中驾驶吗, 但在干燥和潮湿的道路上，在温和的温度下，它们的操控性很好. 这是因为夏季轮胎中使用了较软的化合物, unlike those used in winter tires, become harder in colder temperatures. 而夏季轮胎则增强了性能, 他们往往有较短的寿命和更快的胎面磨损.

Run-Flat Tires

Run-flat tires are a self-supporting type of tire that can be used on light trucks and passenger cars. 开发了比传统轮胎更厚的侧壁, run-flat tires are able to support the weight of the vehicle even when entirely deflated. Run-flat tires are capable of operating without air pressure for 50-200 miles at 50-55 MPH (depending on the tire) while maintaining virtually the same level of ride comfort and handling. 因为任何气压损失都不会被驾驶员察觉, vehicles using run-flat tires must be equipped with a tire pressure monitoring system. 如果漏气轮胎在没有适当胎压的情况下行驶时间过长, they may become irreparably damaged.
