Question:

will these caps typically fit a boat trailer with Bearing Buddies. Concened they may not be deep enough. Thanks!

The inner depth of the Trailer Wheel Center Cap, part # 319EZ is 3-1/8 inches to the tabs on the removable plug on the end of the cap. I am including a picture of the measurement.

To be able to determine if the # 319EZ center cap will fit a boat trailer with Bearing Buddies is to take a measurement on your trailer. You will want to measure on your trailer the length of the spindle that sticks through the center hole of your wheel, from the face of the wheel to the end of the Bearing Buddy cap. If it measures less than 3-1/8 inches then it will fit over the Bearing Buddy caps on your boat trailer.

A bearing buddys outside diameter is slightly larger than 2-1/8. Is the hole in this cap larger than this so the bearing buddy can fit through if needed?

Yes, it could technically protrude through the center cap opening if needed - although I think that would defeat the primary purpose of the unit which is to provide a sleek, streamlined appearance on the wheels.
