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"

These were an excellent, inexpensive and no-maintenance replacement for the standard white painted wheels on my aluminum utility trailer. Like all such wheels, mine started to rust after a year or so and I just put up with them for at least five years. Who has time to refinish and paint utility trailer wheels? I did not want the extra cost or look of aluminum wheels on a basic, well-used trailer. These galvanized wheels, along with the E-rated tires and stainless wheel nuts I bought with them, were the perfect solution for my application. As usual, etailer had the right products at a good price, and with timely delivery. (My only suggestion to etrailer was to offer these wheels and E-rated tires as a package with the tire already mounted, as I believe it is a logical offering for folks with utility trailers.) 319377

Thanks for your purchase and your feedback, Chris. Great news! We offer many E-rated tire and wheel combos at the following link:
-- Laura E - 11/30/2016

A year later the wheels, tires and whee4l nuts still look new. Every time I see them Im glad I spent the small extra amount they cost compared to the basic painted wheels. I feel the same way about the e-rated tires. After 7000 plus miles, they look like new and I know that they can handle the maximum load rating of the axle. I would also note that I had the wheels and tires balanced, which is add that having the wheels and tires balanced is key to their long-term performance.

Received rim in 2 days. Great price and well packaged. Quality of rim looks great! I also bought the high pressure valve stems since the rim comes without stems. Would recommend to a friend and would purchase again if needed. 715783

Ask the Experts about this Americana Trailer Tires and Wheels

  • Should Tires Be Balanced When Installed on Dexstar Galvanized Wheel # AM20134
    If the wheels on your boat trailer are galvanized and are not bent, and seem to be in good condition, you could be having problems with the finish of your wheels. Since the finish of a galvanized wheel is done by applying zinc to the wheel through an electrical charge, you could have a wheel that might not have the zinc applied evenly. This could cause the wheel to have heavy spots. It is not a common problem with a good, quality galvanized wheel. The Dexstar Galvanized Wheel, part #...

  • Lug Seat Angle of Dexstar Galvanized Steel Spoke Trailer Wheel # AM20134
    The Dextar Galvanized 12" Steel Wheel you mentioned, part # AM20134 uses a standard lug bolt or nut with a 60 degree lug seat.

  • Can Wheel # AM20134 Be Used With Appropriate Tires And Valve Stems At 80 PSI
    Yes with some restrictions. The Americana Steel Spoke Trailer Wheel, Item # AM20134, can be used with tires at 80 psi so long as the tires fit the wheel and you do not exceed the wheel's maximum capacity of 1,250-lbs. No matter what tire you use, the maximum capacity will be determined by the lesser capacity of either the wheel or the tire. If you need tires, I recommend the Kenda Karrier S-Trail Radial Tire, Item # AM10140, which has a maximum capacity of 1,520-lbs at 80 psi (greater...

  • Valve Stem and Tire Recommendation for a Americana Steel Wheel # AM20134
    The correct valve stems to be used with your Americana Steel Wheel # AM20134 is the part # AM20903. The Kenda K353 Bias Trailer Tire # AM10068 would be a great choice for a tire for that wheel as well. I attached an FAQ article on trailer tires for you to check out as well.

  • Max Highway Speed Rating for 4.80-12 Tires
    The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel - 5 on 4-1/2 - Load Range B # AM30590 have a max speed of 65 mph. When trailer tires are not speed rated with a letter, the default is 65 mph max. I've attached an article to assist. If you want a speed rating higher, then for that tire size I recommend the Taskmaster 4.80R12 Radial Trailer Tire w/ 12" Silver Mod Wheel - 5 on 4-1/2 - Load Range C # AT12R45SM or # AT12R45WS. These are rated for speeds up to 81 mph. If...

  • Replacement High-Speed Tires for 4.80-12 Tires on Boat Trailer
    The term "high-speed" tires on the sidewall really isn't a good indicator of the speed rating for your current tires because manufacturers have been changing (increasing) the safe speed for tires in the recent past. So if your tires are old enough then they could be rated for 65 mph which used to be known as fast. Since you are looking to replace your current tires and you are looking into options that are rated for higher speeds I recommend using the Taskmaster 4.80-12 Bias Trailer...

  • Comparing The Aluminum Hi-Spec With Steel Spoke Galvanized Finish Wheels
    The Steel Spoke Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - Galvanized Finish # AM20134 has a zero offset. The Aluminum Hi-Spec Series 04 Star Mag Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 # AM20163 also has the zero offset, so there is no difference between the two wheels in how far they sit from the axle hub face. The biggest difference between these wheels other than the aesthetic appeal is the load capacity. The Aluminum Hi-spec has a 270 lb higher load capacity. Both of these...

  • Upgraded 13 Inch Wheels/Tires for a Pontoon Boat Trailer
    The new 175/80-13 tire will be 3-1/2" larger in diameter than the old 205/65-10 tire you have now. This means you will lose around 1-3/4" of clearance. I recommend that you have at least 3" so you will be close but ultimately the choice is up to you. The next size down would be a 145/80-12 (Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire part # AM10140 with Steel Spoke Trailer Wheel part # AM20134) and you will only loose around 1/2" with this size.

  • Recommended 12-Inch Wheel With 5-Bolt Pattern To Be Used As Spare For Trailer
    We do have 12-inch wheels that can be used as a spare for your trailer, but they have a 5 on 4-1/2 wheel bolt pattern. I have attached a helpful article that explains how to measure the bolt pattern to make sure you get the right one. I have also attached a link to the 12-inch wheels with a 5 on 4-1/2 bolt pattern. There are several different styles of wheels. For a steel wheel with a Black powder coat I recommend part # AM20153. for a wheel with a galvanized finish I recommend...

  • Are 12-Inch, 5 on 4-1/2 Wheels With 8 Spokes Available?
    We can check off nearly all of those requirements for you with the Taskmaster Steel 8-Spoke Trailer Wheel # TTW240545WS1 which is a white wheel. Similarly, there is an option in black which meets all but one of your requirements. The Dexstar Steel Mini Mod Trailer Wheel, # AM20153, has everything you want, minus the eight spokes. You may also want to take a look at the Aluminum HWT Series S5 Split Spoke Trailer Wheel - Black, # AM22319HWTB, which has five spokes and black highlights.

  • Recommended Wheels for ST145/R12 Tires On Boat Trailer
    I wish I could help but all of our 12" diameter trailer wheels are 4" wide. If you can give me your bolt pattern and tire size I can then see if we have other options.
