to stick a tyre in the ground = to put a tyre in the ground, and then a car would grow from that. Like planting a seed in the ground and watching a plant grow.

It’s saying that she could plant absolutely anything. Even a car! It’s an exaggeration, of course.

大概是把车子停得深深陷进地里（ '▿ ' ）

couch是沙发的意思，与sofa相同。laugh有名词笑的意思，同时也有动词发出笑声的意思。talent是天才、天资、天赋的意思。chewing的原型是chew，意思是咀嚼。paw名词是动物前爪的意思，也可以形容人的手，但都是用于生气时，算是贬义词。动词有用爪子刨的意思。希望可以帮到你。（ '▿ ' ）
