Bearing buddie size

[acdc96]

I want to replace the dust caps on my trailer with bearing buddies. But I'm having a hard time determining the size I need. I don't know exactly where to measure? Or which one to get?

It's a 1991 Load Rite lil rider bunk trailer with 4.80-8 tires and a 5 lug rim.
I've got calipers and all that stuff.
Thanks in advance

This is straight off the bearing buddy website.

Pop a dust cap and measure the diameter. Buy matching diameter BBs.
