I typically don't use my aero wheel covers unless I am going on a road trip. The problem is that it can be difficult to remove the center caps and the covers will not go on while the caps are in place.
To make things easier on myself, I designed this simple suction cup holding ring. It is small, stores easily in the glovebox and makes short work of getting the center caps pulled out. Just make certain that the center cap is clean and this tool will pop the cap off with a little tug.
Besides the printed ring, you just need an appropriately sized suction cup. I found one that is the perfect size for the job in [this assortment pack available on Amazon](https://amzn.to/39hMKPZ).
