Do I Need Hub Centric Wheel Spacers?

Do wheel spacers need to be hubcentric? Yes, you absolutely need to ensure any spacers mate with the wheel center bore and wheel hub precisely, either by being the correct diameter themselves or with hubcentric rings to make up the difference in size.

Is it safe to drive without hub centric rings?

If you don't use hub centric rings, you transfer the weight of the vehicle to the lug hardware, and the wheel studs will break. Fact is, the hub centric rings do not bear a load. The weight of the vehicle is actually supported by the friction between the wheel and its mounting surface on the axle.

How do I know if I need hub centric spacers?

The easiest way to tell the difference between the two designs is to look at the hub of a hub and wheel assembly. If the hole in the center of the wheel fits snugly against the hub, then it is hub-centric. If there is a gap between the center hole of the wheel and the hub, then it is lug-centric.
