Or John...AKA Jwight, we could freely exchange information, technical specs, experience, and experimentation to arrive at the information necessary to make decisions to prevent a motor or wheel bearing failure.
Like the notion that as you plus size the rim diameter and tire width you must do the math to keep the replacement tire diameter close to the original so all the computers are happy and every safety feature works as designed.
Similarly, to get more options for rims we might need to consider various adapters. Obviously they will add width to the hub spacing. If this is understood then we need to do the math to determine the proposed new rim width, the new hub width and mathematically determine what the proper offset is needed to keep the tire inside the wheel arch (fender).
One important consideration is safety. In this case the available adapters have the potential to upset the steering geometry and might have strength or engineering issues.
Knowing that TUV has certified at least one of the series of adapters from a particular company ensures that:
1. The idea of using an adapter is technically sound.
2. There is at least one source for the adapters that passes very strict engineering and testing to gain the certification.
