前一阵子有人转寄了ABC News的这个report给我。这对我和许\多人都是新的知识，但
是是很重要的知识。跟大家分享一下。
原始email的内容如下∶
You must watch this video http://abcnews.go.com/Video/playerIndex?id=4826897, and go check your tire's age, It doesn't matter if you have just changed them this year. It is very scary if you have no knowledge about the tire fact. Check Your Tires! Take the time to watch this 9 minute video on tires and share with others.
