Also thanks all for the suggestions and suggestions to come...
559mm is the tire bead diameter. Its for 26 tires. If you do the math, 559mm isnt 26, its actually 22. The 26 refers to the outside diameter of the tire when mounted. But, to be even more confusing, the whole system isnt actually 26 unless the tire is 2 tall. Bicycle tires and wheels are a truly confusing system.

As for the wheel, the reason a unwelded joint works is because the rim is held in place by the tension of the spokes. The spoke are trying to pull the round rim in on itself and the rim resists that. Under tension, the joint wont fail even if it looks slightly separated.
