One sign that a wheel has been overtensioned is when the wheel performs a slight s-wave wobble when the tire is inflated. If DEFLATING the tire results in the wheel returning to true or very close to it - then the wheel is overtensioned.
I would have questioned whether the rim is fatigued or not - but the note that it's a new wheel negates that possibility unless by "new" you mean "new" in terms of your ownership.
Since this is radial laced wheel, having a tensionmeter is more important...
Do you have one, and if so, what were your readings translated into KGF?
