Car Hanging in the HDRI background. Unable to ground it in Y Axis

Hi @dubois,

see the below image. I took it from a website using threejs.

The bike is very well grounded on the HDRI image.
But when i tried to implement the same with a car, the Y Aixs seems unreachable. I moved the car in Y Axis direction, the car scaled down to a tiny car and the disappeared at a certain point of calculcation down the Y axis.

My requirement is to ground the wheel on the ground of the HDRI image.

I came across a thread HDRI background position but the solution is unclear for me.

Can anyone brief it with a code or an explanation.
