FAQ

How do I know my center cap size?

Place a tape measure or tape ruler across the opening on the center cap. Measure the inner diameter of the center cap. The inner diameter is the distance between the two inner walls of the center cap, measured in a straight line across the center cap.

What is the difference between hub caps and wheel covers?

A wheel cover covers the whole diameter of the wheel. Central caps cover just the absolute center of the wheel, where the lug nuts and other connective wheel assembly parts are located. Hub caps protect the area of the center cap but typically cover more area.

What do center caps on wheels do?

A wheel center cap covers the center bore. This prevents the impurities from contaminating these parts. Some wheel center caps are big enough to cover all the lug nuts, too. This keeps the lug nuts safe from the elements.

Why do hub caps pop off?

Hubcaps are designed to stay on a vehicle's wheels without falling off; however, they can pop off if the metal grooves on the hub caps wear out and the edges can no longer hold on tight. A vehicle's hub caps may also pop off due to flaws in the manufacturing design.

Can hub caps fall off while driving?

Here are three common reasons hub caps fall off: You hit a pothole or curb – longer and deeper potholes do the most damage, particularly if you are driving fast when you hit and exit them. Hitting or scraping a curb can also cause the hub cap to come off.

Are all rim center caps the same size?

Many people think that center caps are "universal fit" but this is definitely not true. One wheel can have over 30 different center caps.

Can you drive without a center cap?

Yes, you can drive a car without a hub cap, which is used to cover those lug nuts for a decorative purpose only. You can remove all of them if you don't want to have them on your vehicles.

What do you do if your hub cap falls off?

Remove a hub cap (if necessary). If you are replacing a set of hub caps, not just the missing one, use your flat-head screwdriver to loosen the hub cap ring from the tire. Attach the ring to the hub cap. Most come with a metal ring that has a groove in it which will fit around the tire valve.

What is the difference between rims and hubcaps?

Rims are always going to be on the outer edge of the wheel, meeting the tire. Hub caps are added to the wheel. A hub cap by definition covers the hub or center of the wheel, but it can cover the entire wheel. Rims and hubcaps have very different functions. The rim is there to support the tire and hold it firmly to the wheel. The hubcap at best protects the lug nuts from rust or captures them when they fall out.
