I too think that the balance weights are excessive in number; although this can also be caused by tyres that have been made out-of-round.
The fact that your standard rims fit; seems to point to the new rim as the culprit.
An easy check to do is the following:
1. Jack the vehicle and make sure that the bearings are adjusted properly.
2. Place a box, or stand, or sandbag near the rim with a pointer on top of it e.g. Phillips screwdriver. Adjust the pointer so that it is close to, but not touching the rim - at the bottom is a good place. Mark the rim with a chalk mark.
3. Rotate the wheel slowly and note in the vertical plane (ie. looking at the car from the side) if the rim is diametrically round, or not. Record in mm any deviation from prefect concentricity. Note this may involve several revolutions until the pointer is where you want it.
4. Rotate again checking this time for runout i.e. does the rim get close to the pointer and then move away from it - this is viewed in the vertical plane from the front or back of the car. Record the observations.
If the rim appears not be true tell your supplier - a video as evidence might be useful.
The same test can be used for tyres. I once proved to my tyre-fitter that the new tyres for my tractor were 25mm out-of-round! The thing was un-driveable at 20km/h; the replacement was 6mm out-of-round, which still leads to an uncomfortable ride.
Good luck!
Cheers Charlie
