出廠後放在架上完全未使用過的輪胎，

只要出廠超過6年以上，都可能帶來致命性的危險。

購買輪胎時，

請特別要注意檢視輪胎內徑邊緣上橢圓形小圓內的數字，

即代表該輪胎的出廠日期，例如：

231 - 23th week of year 1991
459 - 45th week of 1999
1301 - 13th week of 2001
4202 - 42nd week of 2002
 
另外，在駕車過程中，千萬不要單手駕車耍帥！

雙手應隨時掌握方向盤，以避免車輛突然爆胎時，

失控翻滾，危及自身及家人等的生命安全。

Most of the time this does not happen,

but it certainly can happen.
 
Those who drive trucks as I did probably learned this

a long time ago.

I have known about the age or tires for a long time..

I just did not tell anyone.

I just considered it common knowledge.

Apparently not.
 
Please do watch this video. It is very informative.
