When you ride in mountains, you can just put reTyre over your base tyres. Its just like how we put on different clothes depending on the weather.

这里的how的意思是啊，在我看来更像是无语义。

When you ride in mountains, you can just put reTyre over your base tyres. Its just like how we put on different clothes depending on the weather.

从语法上讲，like 是介词，介词后面不可以跟陈述事实的 that 从句，但可以跟 wh-word 引导的从句。所以，用连接副词 how （也含有w和h）引导从句，符合语法。至于句意，how 表示方法的意思，可以无需翻译出来。又如：

Its so beautiful how the water reflects the sky.

本句，how the water reflects the sky 是主语从句。

how 等于 that。可以代入句中替换。

又如，以下两句意思相同：

It was boringhowhe kept complaining to his wife.

It was boringthathe kept complaining to his wife.

【翻译】当你在山中骑行时，你可以在你的基础汽车轮胎上加上reTyre。这就像大家（怎么样）依据天气穿不一样的衣服一样。
