Weird Stuff, I was home last month and went for a quick ride in my woods and pulled one of my valve stems out of my tire,( good year raw hides)...I tried to break the bead to fix and i could not, I used a 2X6 on the tire and drove my SxS on it and the bead would not break, the side walls were to soft IMO.....I will have to take it to a shop too get fixed now..errrrrrr
