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"

  • Replacement Trailer Hub Assembly for Dexter 8-248 Hubs
    The Dexter "8-248" is a hub assembly for 3,500 lb axles that uses an L68149 inner bearing and a L44649 outer bearing. This hub assembly was offered in both 5 on 4-1/2" and 5 on 4-3/4" bolt patterns therefore you would need to confirm your bolt pattern in order to choose the correct hub. I have attached a help article to help you find this as well. I have also attached my recommendations on each hub for you below. Dexter: 5 on 4-1/2" - part # 84545BX 5 on 4-3/4" - part # 845475UC1

  • How to Determine Hub and Spindle Size
    The spindle dimensions are as follows: A is the mounting dimension, B is the seal dimension, C is the inner bearing surface, D is the outer bearing surface and E is the diameter of the threaded portion of the spindle for spindle nut selection. Say you need a spindle and hub for a wheel with 5 on 4-1/2 inch bolt pattern and an axle that is 3500 lbs. For a single axle trailer you can use two of either the item # TRU64FR, if your axle is round or item # TRU47FR if your axle is square. Then...

  • How to Determine the Correct Hub for My MacGregor Sailboat Trailer
    Determining the correct wheel bearings, seals or hubs for a trailer is normally done by using the existing inner and outer wheel bearing part numbers and grease seal part number. This is the only way to be sure that the correct parts are ordered. The bearing part numbers will ensure that you get the proper size and weight capacity parts for your application. When replacing the hub you will also need to be sure that you measure the wheel bolt pattern (see link) and, if the axle capacity...

  • What Wheel Backspacing Is Needed To Use Timbren Axle-Less Suspension ASR3500S06?
    Trailer axles like the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle - Regular Tires - 3,500 lbs # ASR3500S06 you were looking at are designed to work with trailer wheels that have 0 offset, so you will want to make sure the wheel you use has 0 offset.

  • Looking For Replacement Idler Hub For Old Farm Trailer
    Hey Steve, thanks for reaching out. We currently offer only one hub that uses the # LM67048 outer bearing and # L68149 inner bearing, and that is the Dexter # 8-407-5UC3-EZ which is a hub and drum assembly. It has the 6 on 5-1/2" bolt pattern which is standard. We do not offer a non-braking hub that uses this bearing combination so the only way to use this hub would be if you installed brakes. A lot of older trailers use spindle sizes or bearing combinations that are not standard anymore...
