2) roll from the tow vehicle is only seen as a change in Direction not a steering input such as in the y-axis lockout causing the tire to roll up on its side / lift one corner of the tire by changing the amount of weight on that section of the tire it changes the diameter / circumference from one side to the other. Somebody correct me if I'm wrong but I think that's why aircraft tires are so balloony, so that when the plane lands with excessive yaw the tires physically getting smaller where it wants to grow and the tires getting physically larger where it wants to shrink the circumference counteracting the tendency to Be a steering input.
The effect should be minimal and only a consideration. Motorcycles do not have to lean but 5° or less to change lanes no steering inputs involved.
