The Phoenix USA Baby Moon Hub Cover part # PXQ1401B fits a 221mm hub bore which is 8-7/8" in diameter. Since the baby moon is designed to cover the hub bore then it most likely is not going to fit a smaller 8 inch wheel. You would need to measure the hub bore of the wheel to see what size baby moon you need to fit.

The correct way to measure for baby moons is to take two measurements. You need the measurement from the outer diameter of the inner ring and outer diameter of the inner ring with tab. I have attached a diagram of what that will look like. The inner diameter of the ring with the tab needs to be 8-7/8" diameter to fit PXQ1401B.
