Note that they are thin stamped metal, so don't hammer on them, & remove them yourself before taking the car to a tire shop, mechanic, etc., & many have cut a short section of PVC pipe to fit over/around the raised portion & land on the outer lip to tap them into the wheel, & a smaller pipe to fit inside the wheel from the back to pop them out safely (remember to smooth & deburr the cut edges of the PVC).
You can find a PVC pipe coupler at Lowes/Home Depot that, with a little sanding, will work for both removal and installation. You have to sand the outside of the flange down to fit snugly into the center of the wheel, and you have to take 1/8 inch off the inside to make it fit over the cap and touch the flange for installation.
And if you use it a lot, it will shave off the remover side on the sharp edge of the cap.
But it beats the tire monkeys using an hammer handle to bash your pristine center cap out of the wheel.
