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 Americana Tires and Wheels - Wheel Only - AM20001 Review

Today were going to review part number AM20001. This is the Americana Steel Trailer Wheel in white and this is in the size eight inch by 3-3/4. This wheel is made of a sturdy steel construction. Has a nice white paint finish, which is a powdered coat finish that will help resist corrosion. This is a high quality wheel which will meet the DOT specifications. The few specs on this wheel, the rim dimension is eight inch diameter by 3-3/4 wide.

Basically, when we go to measure that, the diameter is actually not measured end to end, its measured beat sit to bead sit. In other words, where the tire would sit on this wheel, youll measure bead sit to beat sit to get the diameter. If we do bead sit to bead sit, it will be eight inches. To get the width, it will be the same way, we dont measure end to end, edge to edge, we measure bead sit to beat sit again where the tire would sit. Getting this would be 3-3/4 inches.

This wheel would be eight inch diameter by 3-3/4 inches wide. Has a bolt pattern of four on four inches and the way that is measured is first of all, the four means four lugs, as you can see the four lug holes. The four inch pattern would mean that if you drew a circle between all four those lugs, the center of all four those lugs the diameter of that circle would be four inches. The best way to measure the bolt pattern on a wheel that has even number of lugs like in this case four, just go center to center, as you can see four inches. This tire use a wheel bolt size of inch by 20.

The weight capacity on this wheel is 910 pounds. The pilot diameter which is the large hole here in the middle that goes over the hub on your trailer will be 2-1/2 inches. This wheel does come with a limited one-year warranty. That should do it, for the review on part number AM20001, the Americana Steel Trailer Wheel in white and in eight inch by 3-3/4 inch diameter. .

This is not the first time I have purchased from etrailer, every time I've always gotten exactly what I ordered at the best price. The shipping has always been prompt, usually right on the promised date and sometimes sooner. All of the parts on my order are to re-equip a small boat trailer. The AM20001 wheel was exactly what I ordered, quality and finish is excellent. The Kenda Loadstar tires I also purchased also appear to be excellent quality, no pictures yet to share. Thank you again for your great service. 601559

I have yet used the wheel rim products only because I need time to reinvent the use of these items. But I have to commend the service and personal touch I believe Lisa helped. An absolute doll and I thank you. Still going to work with the wheels. Will definitely recommend this company. 569417

This rim is made of very strong steel and the finish is impeccable. It is smooth on both sides and there are no rough edges anywhere. The white paint held up to the mounting of a new tire and did not scratch. I am very impressed with the quality, fit, and finish of this rim. I mounted the spare tire on my boat trailer as one did not come with the trailer when I purchased it. This is an outstanding product and I highly recommend's products for all trailer needs. 468609

These rims are outstanding quality. I give them 5 stars, but mine came with a few chips in the powder coat. I'm painting them a different color, so I didn't mind. 304478

The wheels that i ordered were exactly what i needed to get my troybilt tiller up to speed with new tires, since the original wheels were no longer available for my model i had to make a hub to attach to the axle shaft on the tiller and then bolt the wheels and tires to the hub. 241945

Great Rim after the measure instructions, and it made a perfect fit. I am not sure why they no longer just list the tires that fit rims to make ordering easier. Just measure with the measuring instructions on their page. But this works great and is a very strong rim . Fast service as usual. 123526

  • Is there a Limit to How Long Trailer Tires can be Driven at Maximum Speed Rating
  • Most trailer tires do indeed have a speed rating of 65 mph, although there are exceptions. There is not a particular amount of time that you are limited to when traveling at this speed, so long as you do not exceed the 65 mph limit. You should also make sure that the tires are always inflated to the maximum psi as listed on their sidewall, and that you do not exceed the combined load capacity of your tires with the loaded weight of your trailer.

  • Can 8 inch Trailer Rim AM20001 be Used with Higher Capacity Tire that Needs 100 PSI
  • The Steel Trailer Wheel # AM20001 that you referenced has a weight capacity of 910 lbs and would only be limited by the valve stem for PSI. You can use the tire you mentioned on this rim but you'd be limited to 910 lbs capacity. For a valve stem to use with this wheel that is rated for up to 200 psi you'd want the part # AM20906.
