关于轮胎修理我需要知道什么?

  1. 驾驶未正确修理的轮胎非常危险。不正确的修理可能不可靠或导致轮胎进一步损坏。轮胎可能突然损坏,造成严重的人身伤害或死亡。应由合格的轮胎服务专业人员按照橡胶制造商协会 (RMA) 程序对轮胎进行全面检查和修理。

  2. 正确的轮胎修理包括以下内容:

  3. 将轮胎从车轮上拆下,进行内部和外部的全面检查。轮胎的一些损坏可能仅在轮胎内部显现出来。
    穿刺损伤应为 ¼ 英寸(6 毫米)或更小,且必须位于胎面区域内。这有助于确保轮胎和修补件的长期耐用性。
    在轮胎内部贴上补片,并用合适的塞子/填充物填充穿刺孔。这有助于确保轮胎内部充分密封,防止充气压力损失,并防止钢带和其他帘布层受到外界元素(如水)的污染。
    关于轮胎修补的附加说明:

  4. 并非所有被刺破或损坏的轮胎都能得到妥善修复;因此,有些轮胎必须更换。切勿在下列情况下修理轮胎:
    磨损至轮胎内置胎面磨损指示器或胎面任何区域的剩余胎面深度为 2/32 英寸(1.6 毫米)。
    穿刺孔大于 ¼ 英寸(6 毫米)。
    可修复胎面区域外有穿孔或其他损坏。
    存在预先存在的不当修复。
    任何未将轮胎从车轮上拆下就进行的轮胎维修都是不恰当的。必须将轮胎从车轮上拆下,然后检查轮胎内部是否有损坏,而这些损坏可能在轮胎外部看不到。
    仅使用塞子/阀杆或仅使用补丁不是安全或正确的修补方法。必须在轮胎内部打补丁,并用合适的塞子/阀杆填充物填充穿刺孔,以防止充气压力损失和钢带和其他帘布层的污染。
    切勿为了进行正确的修理或纠正不正确的修理而更换管子。
    内胎和轮胎一样,只能由合格的轮胎维修专业人员进行修理。
    有些汽车制造商不建议使用修补过的轮胎。在车辆上使用修补过的轮胎之前,请查阅车主手册或联系汽车制造商。
    如果轮胎经过修理、翻新、损坏、滥用或以其他方式改变其原始状态,则轮胎的速度等级将失效。应将其视为非速度等级轮胎。

轮胎换位的正确方法是什么?

  1. 4 轮胎换位
    您是否知道前轮驱动车辆的前轮磨损速度几乎是后轮的两倍?另外请记住,轮胎磨损不均匀可能是由于悬架错位等机械问题造成的。平均而言,轮胎应每行驶 5,000 英里换一次,高性能轮胎的换次频率应更高。

  2. 车轮平衡
    您是否感觉到方向盘在 50 至 70 英里/小时之间振动?车轮不平衡会导致操控性不佳,并显著降低燃油里程。我们建议在每次轮胎旋转时进行车轮平衡。

经常问的问题

  1. When buying just two new tires, should they be put on the front or rear?

    When you select a pair of replacement tires in the same size and construction as those on the car, you must put them on the rear axle. A single new tire must be paired on the rear axle with the tire having the most tread depth of the other three.

  2. How much air should I put in my tires?

    Proper inflation is the single most important part of tire care. The inflation pressure on the side of the tire is the MAXIMUM operating pressure. It is not necessarily the right inflation for your vehicle. Always use the inflation recommended by the vehicle manufacturer. You can find it in your owner's manual, posted on the edge of the driver's door, on a doorpost or on the inside of the glove box door. Always check inflation when tires are COLD: when the vehicle has been driven less than 1.6 km or one hour or more after driving. Use a good quality tire gauge. Note: It is natural for radial tires to have a slight bulge in the sidewall at their proper inflation pressure. Check or adjust inflation every few weeks, before any long trip or if traveling with a heavy load.

  3. What is alignment?

    A vehicle is said to be properly aligned when all suspension and steering components are sound and when the tire and wheel assemblies are running straight and true. Proper alignment is necessary for even tread wear and precise steering. Uneven front- or rear-tire wear, or changes in your vehicle's handling or steering response (i.e. pulling to one side) can indicate misalignment. Many vehicles today are equipped with rear suspensions that can be adjusted for alignment. Your vehicle may need a "front-end" alignment or a "four-wheel" alignment, depending on the symptoms you are experiencing. The moderate cost of having your vehicle aligned can more than pay for itself in tire kilometrage, performance and comfort.

  4. What should I do if I notice a vibration?

    Vibration is an indication that your car has a problem that needs attention. The tires, steering system and suspension system should be checked to help determine the possible cause and correction of the vibration. If left unattended, the vibration could cause excessive tire and suspension wear. It could even be dangerous.

  5. Why do my tires need to be balanced?

    Properly balanced tires are important for driving comfort and long tire life. Unbalanced tires can cause vibration, resulting in driver fatigue, premature tire wear and unnecessary wear to your vehicle's suspension. Tires should be balanced when they are mounted on wheels for the first time or when they are remounted after repair. Tires should be rebalanced at the first sign of vibration or "shimmy." Vibration may also be due to misalignment or mechanical problems.

  6. Do my new tires require any special treatment?

    Your new tires will probably feel different from the tires that were replaced. Drive carefully as you become familiar with their performance and handling. Take special care when braking, accelerating, cornering, or when driving in the rain, because these are the times when the differences will be most noticeable.

  7. How long should my original equipment tires last?

    Due to the variety of styles, construction features, tread compounds, vehicle applications, geographical conditions and driving habits, it is difficult to provide specific kilometrage expectancy. However, any tire wear concern should always be presented to your local Costco Wholesale tire center for further evaluation.

  8. Is it easy to mount a tire on a wheel? Can I do it myself?

    Never try to mount your own tires. Tire mounting is a job for the people who have the proper equipment and experience. If you try to do it yourself, you run the risk of serious injury to yourself as well as possible damage to the tire and rim.

  9. Must I replace my present tires with the same size tires?

    Never choose a smaller size than those that came with the car. Tires should always be replaced with the same size designation -- or approved options -- as recommended by the vehicle manufacturer.

  10. Should I "mix" tire types on my car?

    Tires of different size designations, constructions, and stages of wear may affect vehicle handling and stability. For best all-around performance, it is recommended that all tires be of the same size, construction (radial, non-radial), load capacity and speed rating.

  11. How can I check my tires for wear problems?

    Tires often give their owners signs of problems in plenty of time to have them corrected. Learn to "read" these early warning signs and you can prevent many wear problems that shorten tire life by thousands of kilometres. Consult your Costco Wholesale tire sales associate for further information.

  12. How do I know when I need new tires?

    Many tires have tread wear indicator bars molded into the tread. When the tread is worn down to where you can see a solid bar of rubber across the width of the tread, it is time to replace the tire. Here is another simple test you can perform to measure tread depth on your tires. Place a penny into a tread groove with Lincoln's head upside down and facing you. If you can see the top of the Lincoln's head, it is time to visit Costco Wholesale for a new tire.

  13. Should I rotate my tires?

    Regular and proper tire rotation promotes more uniform wear for all of the tires on a vehicle.
