Initial speed for a vehicle

Hi all!
I need to set initial speed value for my AWheeledVehicle pawn with UWheeledVehicleMovementComponent4W component.

I tried to set impulse with disabled friction on tires. After some ticks, I am enabling friction on tires. Everything works fine but the vehicle continues to move like it hasn’t any friction.

Also, I tried to set initial speed with SetAllPhysicsLinearSpeed. The same effect as above.
