car sliding

[_MAID]

hello all,

I try to create a vehicle, I use it for functions 'CustomDGRayCastCar'.
It works well, only my car slides on the ground, making it totally uncontrollable.
Apparently it is not possible to assign a material to the wheels, so I do not know
how to control the slippage between my wheels and my ground.

I searched the forum but I have found answers that I can understand.
how to make sure my wheel grip on my land ?

thank you .

No answer to this? A little glimpse on the problem at least? Some speculation what's causing the slippage? I'll try and fix it.
