You could do like my Snowmobile does and just have 4 invisible wheels, but you should put the wheels where it would keep the vehicle balanced out and where you would want the tire particles to come from, like this

And if you want your vehicle to be closer to the ground, just make the wheels smaller
is it possible to have a face on a model only render on one side? for example a window that is opaque on one side but not the other
By default, any faces you make are one-sided, so if you made a windshield, it would just be opaque on one end, but completely transparent on the other
But if it's opaque on the wrong side, you can flip the normals of the face to fix that
