HF portable tire changer

HF one works ok on radial car tires as long as they are not low profile. My buddy used it to mount 16" E rated trailer tire with high pressure stems. He is in much better physical shape than me as I have had several back surgery's. He worked his *** off with with the stiff sidewall. He did a couple and said he was going to the tire store up the street and have them do the other four. This thing will give you a real workout thats for damn sure lol!
