Why not take it to your trusted tyre fitting establishment and ask them to check it.
Many years ago when I was still very inexperienced at this car maintenance stuff I had a vibration issue. A tyre fitter eventually traced the sojrce of the vibration. One of the road wheels was very slightly out of true. Not obvious when being spun whilst on the car but could be seen when spun on the wheel balance rig. The structure of the wheel was found to be sound but it was definitely not true.
On the other hand, last year I left two of my 940’s original steel road wheels to be blasted clean and powder coated prior to having new tyres fitted. Once blasted it was obvious that one of them was so badly corroded around the rim that it was scrap. The other was quite acceptable and re-useable.
