You tighten both sides by hitting them towards the rear and loosen by hitting them forward. The centrifugal force of the wheel going forwards assist in tightening the spinner backwards.

Be careful to always keep the spinners on the same side of the car once removed, do not toss them all together unless you have marked them in some manner. The racers would sometimes paint the spinners red for one side and blue for the other in case they got mixed up.
