thumbtack

Also there is a more sarcastic way, which is not recommended, that is, put a thumbtack into the tire.

还有一种更损的方式，不值得推荐，那就是在车胎上按上个图钉。

"It was my big hope that people would get [the message] right away and at least put a thumbtack on the map as far as our location, " Buck said.

“我最大的愿望是希望人们能够立即收到（这条信息），哪怕在我们所处地方的地图上钉一枚图钉也好。” Buck说。

Someone pulls the thumbtack out of the tire, which makes it hard for the owner to find where the hole is.

有人按了图钉再拔下来，这样车主找不到窟窿在哪儿，补胎时更困难。
