How To Keep Center Caps from Falling Off

You’ve probably noticed that a lot of new wheels lately have center caps. These caps, which fit over the center hole on your wheel, help keep dirt, gravel and water out of the hole. But they can also cause problems. Many riders say that the caps keep falling off. So, how do you keep center caps from falling off? 

Fortunately, there are a few things you can do to keep your center caps from falling off. This article will teach you how to keep center caps from falling off your wheels, so keep reading to learn more about it.

What are Center Caps?

Center caps are a type of wheel accessory that adds a decorative accent to the center of your wheel. They usually sit right in the middle of your wheel, blending right into the design. They’re only a few millimeters thick, so they don’t add any extra weight to your wheel.  Center caps look similar to performance wheel covers, but they’re made from different materials. 

Some are made from plastic like anodized aluminum center caps, while others are made from rubber like running shoe covers. Self-aligning caps are just like standard center caps, but they have an internal mechanism that makes it easy to center them on your wheel.

How to Keep Center Caps from Falling Off

Center caps are often blamed for falling off because of the way they fit on your wheel. They’re sometimes too small for the hole in your hub and fall off. You can’t do anything to prevent the center cap from falling off. But, there are things you can do to keep it from falling off.  The first thing you can do is make sure your center cap is centered correctly. 

After you’ve installed your wheel, you should center your cap by hand. If your center cap is too large or too small, it will loosen or tighten up when you torque your wheel. This can loosen or tighten up your lug nuts and make it easier for them to come off.  

There are three main methods to keep your center cap from falling off:

  • Don’t mix and match
  • Install brand name center caps 
  • Install self-aligning centers

Don’t Mix and Match

When mixing and matching different types of wheels, it’s important to keep different types of center caps separate. For example, you wouldn’t combine a running shoe center cap with an anodized aluminum center cap, because they’ll both get loose. It’s also important to keep different types of center caps separate because they sometimes don’t fit together very well. This can cause your center cap to be too loose or too tight.

Install Only Brand-Name Center Caps

A lot of center caps don’t fit very well and can cause problems with your wheel. It’s best to stick with one type of center cap for your wheel. This includes performance and street center caps. But, there are a few specialty center caps that can be used with cars. 

For example, the backflip center cap can be used with disc wheels. And, the disc brake cap can be used with disc wheels. You don’t need to install cap-specific parts. You just need to make sure your wheel and hub fit the specific center caps.

Installing Self-Aligning Centers

Self-aligning centers are like a cap with a built-in mechanism that makes it easy to center on your wheel. This can be helpful when you’re replacing your wheel. If you’re changing your wheel size, you might need to change the axles on your hub.  

Self-aligning centers can help you center your cap because they generally have an axle with a built-in mechanism. After you’ve centered your cap, you just need to snake the axle through your wheel’s axle hole. As long as one end of the axle matches up with the end of the axle hole in your hub, your cap should stay in place.

Why Do Wheel Caps Fall Off?

There are a few things that can cause your cap to fall off. The first is a loose fit. You might have to use a wrench or pliers to make sure the cap fits tightly on the end of your axle. You also might need to make sure it’s centered on your hub before you tighten it down. If you don’t, one side of your cap will tend to be tighter than the other, causing it to eventually fall off.

The second thing that can cause caps to fall off is damage or poor maintenance of your hub and wheel. If there’s too much play in either one, they won’t be able to align with each other correctly. 

This can cause caps and nuts on the end of axles and hubs to loosen up over time. It also makes it more likely that they will come loose while you ride or crash, sending them flying off into traffic or underfoot during a crash landing.

If you’re having trouble with your wheel caps, you should check your hubs and rims for damage and wear. You can also try using a different type of cap. Some companies make caps that screw into the end of your axle instead of using a nut or bolt. You may find that these stay in place better than regular caps, especially if you have to remove them often (like when you’re transporting your vehicle).

Can You Glue Center Caps On?

It’s possible to glue your center cap on if you want to. However, it’s not necessary. If you want to glue your cap on, first use a screwdriver to remove the existing cap. Then, clean the underside of your wheel with rubbing alcohol and let it dry completely.

 Next, mix some epoxy resin and apply it to the underside of your wheel where the center cap will go. Place the center cap on top of this mixture and hold it in place for a few minutes while it dries.


Center caps are easy to install, but some of them can cause problems. If you’re worried about your center cap falling off, you need to make sure that it’s centered correctly. You can also make sure that you’re using a cap that fits well. These tips should help you keep your center cap from falling off.
