What's the situation on the rims and tires? I would recommend having them balanced on a machine that checks "road force variation" and rim runout. I've seen new tires that will balance, but have excessive road force which still gives you a vibration. I would recommend anyone that's going to get tires balanced find a shop that has this newer machine. Like this-- Hunter And go here to find a shop that has one... Locator Just for the record I don't work for Hunter or get a kick back . Good luck
