The reason it's easier to Skid a smaller tyre isn't because of a change in surface friction, but because sideways force is spread over the contact point. Smaller contact point = much greater concentration of force.
But there is more to 'control' than merely surface friction. There is also balance, which is greatly effected by how big your contact point is and how it moves underneath you.
Max, I had no idea you weren't British.
