Dead-cat hole refers to the space between the top of a car tire and the body of the car, in other words, the space between a car's tire and the wheel well.
Dead-cat hole(死貓洞)指汽車輪胎上部與車體之間的空隙,也就是汽車輪胎和輪倉之間的那個空隙。
For example:
US models will have larger dead-cat holes than European ones.
美國版的車上車輪和輪倉之間的空隙要比歐洲版的大一些。
