I have to disagree with the ether trick. I used to do it a lot when I had a 4x4 shop in the 70's, until I went on a squad call where a tire blew up. I can tell you it was not pretty, the guy was just about cut in half! I did some research on it and found out it is VERY dangerous. All it takes is one tiny loose piece of rubber, lint, whatever to get partially burned when the ether lights off and then the tire seals and the rest of the oxygen is gone. The hot spot is still there along with any left over ether at a temp plenty high enough for an explosion. All it needs is oxygen. Now when you do this trick most people will leave the valve stem out because as soon as the tire seals there is a vacuum created in the tire due to aforementioned lack of oxygen. If the valve stem is in the tire will usually pull back off of the rim. If the valve stem is out then air can get in to relieve the vacuum. What does air have in it? oxygen. Remember that little hot spot and left over ether? KABOOM! Now I know everybody is going to say well use less ether. How much is enough? how much is too much? I sure as **** will not do it anymore I can tell you that.
