The forum appears to be struggling again, I was able to rt click and open the image in a different tab before it disappeared and the wheel looked very similar to the set I had on my little sports car. A search confirmed that they are very likely to be HP Design wheels and I had the same problem as a result of a tire installer using the wheel balancer to punch the center caps out which snapped the retaining tabs off. The center cap is not cheap either and will probably be difficult to find at a reasonable price if at all as I'm not sure they're still in business. I purchased my HP wheels back around 2010. ASA and TSW are possibilities also, but HP is the closest resemblance I have found.
