also the inverse problem, the braking force/torque is also reduced by the

I don't understand the reduction in braking force, can you elaborate?

If the tires get bigger but the brakes don't the tires will have more
leverage. Imagine shrinking your existing brakes down to the size of a
quarter -- you'd have no trouble turning the wheels by hand, the
leverage would be so great.<br>
