I found out many years ago that you can't run tubes in tubeless tires, the tubes will fail every time, usually where the tube intersects with rim.. If you do use tubes in a tubeless tire the tubes must be for tubeless tires.
As a precaution it might be a good idea to seal around the rivets on older wheels if tubeless tires are used. There are stems available that will seal to the rim with rubber gaskets and a locking nut.
It is also not a good idea to use radial tires, mixed with bias ply on a steering axle. Radial tires on the drive axle with bias ply on the steering axle is OK.
