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 - 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 - 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 - Side

Measuring the distance 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"

Video Transcript for All About the Steel Trailer Wheel

Today we're going to take a look at the Americana 8" x 3-3/4" Galvanized Steel Trailer Wheel with the four on four-inch bolt pattern. Now this wheel is a nice sturdy steel construction. It does have the galvanized finish to provide superior protection from rust and corrosion, and the galvanized finish wheels are usually used in marine application where you're going to be around freshwater or saltwater. This is a high-quality wheel. It does meet the DOT Department of Transportation specifications.A few specs on this. We're going to measure the diameter which is eight inches.

And when we measure that, it's not going to be edge to edge, it's going to be inside to inside. So if we take our tape measure, go inside to inside, there is your eight-inch diameter. The width on it is the same way. It'll be inside to inside or bead seat to bead seat. There's your 3-3/4 inches wide.The bolt pattern on this wheel is going to be a four on four- inch bolt pattern.

If you want to measure that on a wheel that's an even number of lugs, in this case four, all you have to do is pick one of the holes, measure from the center of that hole directly across to the center of the hole right across from it. That'll be four inches, so four-lug four-inch bolt pattern. This wheel does use the wheel lug size of 1/2" by 20. And the pilot hole diameter, which is the large hole here in the center of the wheel that goes over the hub on your trailer. The diameter of that opening is 2.5 inches.

And the weight capacity on this wheel is 910 pounds.But that should do it for the review on the Americana 8" x 3-3/4" Galvanized Steel Trailer Wheel with the four on four-inch bolt pattern.

  • What Degree Lug Nut Fits 8" Americana Steel Trailer Wheel
    Thanks for reaching out again, Emil! The Steel Trailer Wheel # AM20003 is also compatible with a lug nut that uses a 60-Degree cone like the Taskmaster # TA66QR. Is there something specific I can help you find to make sure we get your trailer back up and running?

  • Replacement 8 x 3-3/4 inch Trailer Wheel for 4.80-8 Sized Tires
    I won't say you can find an 8 x 3-3/4 inch rim just anywhere but you've come to the right place. We carry two of them; parts # AM20001 which is white and # AM20003 which is galvanized. They're both a 4 on 4 and have a maximum weight capacity of 910 pounds. These are the correct size wheels for 4.80-8 sized tires like you have. We also carry a 4.80-8 tire mounted on a white wheel with a 4 on 4 bolt pattern, part # AM30000 which has a weight capacity of 590 pounds at 60 psi.

    You will need to order the Kenda K353 Bias Trailer Tire # AM10013 and Galvanized Steel Trailer Wheel # AM20003 separately. You can either mount them yourself using the Americana Metal, Bolt-In Valve Stem # AM20906 or choose to have them installed at your local tire shop. The Kenda 5.70-8 Bias Trailer Tire with 8" White Wheel # AM30153 is currently the only wheel and tire combo with a load range D tire and 4 lug wheel in the 5.7-8" size.

  • Comparing Design of Galvanized 8 Inch Trailer Wheel vs White Powder Coated Steel Wheel for Capacity
    The Steel Trailer Wheel - 8" x 3-3/4" Rim - 4 on 4 - Galvanized Finish # AM20003 has a center pilot hole that is 2.5 inches diameter. The Steel Trailer Wheel - 8" x 3-3/4" Rim - 4 on 4 - White # AM20001 has a pilot hole that is 2.5 inches diameter as well. We will update our page and the capacity of the two are both already 910 lbs each. The only differences are one is galvanized steel and the other is regular steel with white powder coat.
