When you ride in mountains, you can just put reTyre (a new kind of tyre) over your base tyres. It's just like how we put on different clothes depending on the weather.

从语法上讲，like 是介词，介词后面不能跟陈述事实的 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 表示方式的含义，可以不需要翻译出来。又如：

It's 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 boring how he kept complaining to his wife.

It was boring that he kept complaining to his wife.

【翻译】当你在山中骑行时，你可以在你的基础轮胎上加上reTyre(一种新的轮胎)。这就像我们（如何）根据天气穿不同的衣服一样。
