this ***** didnt let any air out for a few days...
if the problem gets too much for you, send them up to me. i will happily take them off your hands...
seriously though, a wheel alignment is probably what you need.. they might be seriously out of whack, which is why you experience wobble at low speeds... and don't worry about the tyre pressures, they change pressure depending on how warm the tyres are and like bigbum said different pumps show different readings by a couple of psi...
