I have welded on rims with the tires mounted but never with a tube. I always remove the valve core so the pressure never builds up and have never had a problem. I am not saying it's the right thing to do, but with the valve core removed I have done it with no problems. I know I will catch a lot of grief from all the "experts" on here but I don't really care.
