I was running wheels on my car which was universal and had a larger hub, I had no idea I was suppose to use Hubcentric rings to help get the wheel on the car's hub to make it easier to get the lug nuts back on (read: easier, not required.)These rings themselves feel like they would break easy, so I'm curious how long they will last taking wheels on and off the car.Currently I haven't found any flaws in the design or manufacture of the item, the only problem I had was with my wheels and hubs for being off a tiny bit making one of the rings loose (not the ring's fault.)Also as another note, my wheels are lugcentric and not hubcentric, but the hubcentric rings still work good with them.
