I am going to have my snow tires mounted soon, but the wheels need to get cleaned up before mounting them. I'd like to dismount the junk tires I currently have on and sand and re-paint the bead area as the factory paint along the bead is chipping. I am getting slow leaks in cold weather from the bead area as the tires don't want to seat well. I'd rather not have to make two trips to the tire store.

Here is my plan. Does this sound like it will work?

1) Break the bead with a hi-lift jack under the trailer hitch on my wife's minivan and the base on the sidewall.

2) Use Sawzall to cut a few inches through the bead into the sidewall

3) Pry the tire off with miscellaneous pry bars I have around at home.
