Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.


Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)


Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)


Bolt Pattern - Side

Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Dexter hubs are a perfect fit to Dexter brake assemblies. Perfect fit and brake good. Self adjustors keep the trailer brakes always adjusted correctly.

by:

Perfect product



by:

new dexter wheel hubs, delivered on time, new dust caps, new seals (2 1/4") , new lugs and nuts , new bearings. one bearing is the wrong size, but I dont care will pick up locally. these were backordered for most places in western NY, got em just as fast and far better price. will be ordering more soon. currently servicing 6 trailers with this or similar hub.



by:

Received three out of four in great shape. The fourth had damaged parts inside but etrailer sent me new parts. Used these to change from UTG to regular rims. Tire changes so much easier. I always recommend etrailer.



by:

What can I say name brand quality never need to adjust trailer brakes why would you buy anything else. Braking is much more balanced and dependable.

not only am i happy with the product purchased but with the service from etrailer i had to return some parts and they were fantastic to deal with. I would purchase from them again for sure

  • Will Hub with 25580 and 14125A Bearings Fit in Place of a Hub with 25580 and LM67048 Bearings

  • Solution for Replacing Dexter 8-222 Trailer Hubs and Bearings
