Hub Bore Diameter Of 8" x 3-3/4" 5 on 4-1/2" Wheel AM20006

Question:

Hey I’m looking for two trailer rims. They are 8 inch 5x4.5 lug. I measured the width of the rim and it’s 4 inches from bead to bead. The part that screws me up is the center hole is 3.25 inches in diameter. I’m having trouble finding a rim with a large enough center hole. I’m going to measure the hub on the trailer on Monday to double check but they are fairly large. Thanks-Dustin

The only 8" wheels with 5 on 4-1/2" bolt pattern close to 4" wide are the following:

White # AM20006

Galvanized # AM20008

Both of these are 3-3/4" wide, which is measured inside to inside of the bead seat so this is likely what your wheel is. However these are only available with a 2.81 hub bore diameter. As long as your hub bore is smaller than this it'll work fine, but if you need larger you'll have to look elsewhere for the wheels.
