My design is floating for some reason

[mngld75]

The car's shadow isn't connected to the bottom of the wheels for some reason. Does anyone know how to solve this? I'm trying to render it but because of this, the car keeps looking like it's floating. Thanks.

Never mind, I could just move the background directly in render

Hi , 

from scene settings check flatten ground

I don't think "floating" is totally inappropriate!
