Dear all , I'm new in this forum so excuse me if I ask some already answered question or if I?m posting in the wrong area . I have an RV-7 and some time taxing I notice a shimming , a vibration forward and aft of the legs of the main gear , especially when I have to vacate quickly so I need some speed . I have noticed that this happens when I inflate tires at 2,0 - 2,5 bar ( 30 - 40 psi ) ,but if I inflate at 1,6 bar ( 24 psi ) this does not happen ..... can that be true or the pressure of tire does not influence this behavior , is something else ? thanks for answering . Giulio
