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"

After shopping around a lot for wheels to upgrade my trailer looks I was happy to find eTrailer. The website is very helpful and informative and the wheels I received were exactly what I had hoped for. A big bonus was how helpful the eTrailer customer service people were...not common today! I've since bought several other items that have all been top shelf. 874490

The wheel that I ordered was of excellent quality, delivered as promised, and at a very good price! Thank you! 782035

Excellent heavy duty 13" trailer wheel. The galvy finish will last forever. Problem with the wheel is that because the galvy finish is so thick, it must be sanded and smoothed along the inside of the wheel where the tire bead mounts in order to get the tire to seal and stop leaking. Had to mount and unmount tires twice in order to get that done. Quality control begins at the factory in this case; etrailer should 'encourage' supplier to make sure this is done before sending out the wheels. 738315

Very pleased with the wheel and tire, great products. And great service. Thanks Brenden 664702

- AM20224

These 13 inch wheels came to me in perfect condition. They are for my boat trailer as my 12 inch wheels are too small for the weight I need to carry. These new galvanized wheels along with my new tires is a beautiful fit on the trailer to carry the weight. Thank You for the wonderful product! Bryan R. Middle Georgia 406970

Great, Thanks!!

Bought these rims to replace painted steel rims on a boat trailer. It was difficult to find the 4 bolt version of this 13" rim. I had bought the 5 bolt style a few years back for another trailer and at that time I noticed that etrailer did not list a 4 bolt. After a phone call with a very pleasant girl, the 4 bolt style was listed on the website. Thanks so much. 207353

- AM20224

These rims were in terrible condition. Talking with a respectable tire business that mounted my tires on these rims I purchased told me that the galvanized was the worst that they have ever seen. I needed 13inch and would have bought from them. Unfortunately they didnt have 13's. The other parts i purchased was ok, but etrailer had to order my rims and delayed shipping. 160931


Ask the Experts about this Americana Trailer Tires and Wheels

  • Recommended 13 Inch Tire and Galvanized Wheel With 4 on 4" Bolt Pattern for Boat Trailer
    We have a couple of different options for you to increase your tire size and load capacity, although there is not a 14 inch wheel with a 4 on 4" bolt pattern as those size wheels are at least 5 lugs. What you can do is move up to 13 inch wheels and tires, and you have a couple of different options. The one I recommend is the Steel Spoke Trailer Wheel - Galvanized # AM20224 with the Kenda Karrier ST185/80R13 Radial Trailer Tire # AM10208. The reason this is the best option is because...

  • How is Total Trailer Tire Capacity Determined for a Trailer with 2 Axles
    You are correct. To determine the tire capacity that a trailer has you would need to add up the capacity listed for each of the tires. So if you have a 3,000 lb total weight trailer you would need each tire to have at least a 750 lb capacity. For your tire size that wouldn't be a problem at all. For example the part # TR20514 has a capacity of 1,760 lbs at 50 psi so on a tandem axle trailer you would end up with 7,040 lbs of tire capacity. This tire is unique in that it has a speed...

  • Available 10-Inch and 12-Inch Trailer Wheels
    Our entire range of trailer wheels can be seen on the page I linked for you. You can click on the wheel and/or tire size to see just the options in that size. For instance, the Kenda 10-inch wheel/tire # AM3H480 has a 5-on-4-1/2 wheel bolt pattern and a pilot hole diameter of 2.8-inches. Part # AM3H340 has a 4-bolt pattern and a 2.5-inch pilot hole. Many wheels in this size have a larger 4-inch pilot hole diameters, such as # AM3H454. You can find the pilot hole diameter in the specs...

  • Availability of a 13 inch Wheel With a 4 on 4-1/2 Bolt Pattern
    I might have a solution for you, but we do not carry any wheels that have a 4 on 4-1/2 bolt pattern. We do offer 13 inch wheels with the very common 4 on 4 bolt pattern which may be what you are measuring. Since your wheel has an even bolt pattern you will want to measure the bolts that are directly across from each other center-on-center. I have attached a helpful article demonstrating this. If your bolt pattern does turn out to be 4 on 4 then we have a variety of wheels for you...

  • Will Americana 13" Spoke Trailer Wheel Fit 4 on 3-1/8" Bolt Pattern
    I believe you are referring to the 13" Steel Spoke Trailer Wheel # AM20224 that has the 4 on 4" bolt pattern. From what you said I'm guessing that you measured inside to inside for the bolt holes because I've never heard of a 4 on 3-1/8" bolt pattern. Since you have a 4-bolt pattern you need to measure from the center of one bolt hole directly across to the center of the bolt hole across from it. This should measure 4" which would mean that you have a 4 on 4" bolt pattern. Attached is...

  • Westlake ST175/80R13 Radial Trailer Tire With 4 on 4 Bolt Galvanized Wheel
    It is possible to get the Westlake ST175/80R13 Radial Trailer Tire part # LHWL101 mounted on a 4 on 4 galvanized bolt pattern wheel. For that I recommend Steel Spoke Trailer Wheel - 13" x 4-1/2" Rim - 4 on 4 - Galvanized part # AM20224. The tire and wheel would come separately so you would need to take them to a tire shop to have them mounted. We currently do not carry the Westlake ST175/80R13 tire pre-mounted on a 4 on 4 wheel.

  • Tracker Pontoon 13 inch Trailer Wheel Recommendation
    The rivets you described are just for looks and do not serve an actual purpose. For a 13 inch wheel with a 5 on 4-1/2 inch bolt pattern in a galvanized finish the part # AM20234 would work for you. Or if you have a 4 on 4 inch bolt pattern the # AM20224 would work. Galvanized wheels are great for boat trailers since they do a great job fighting corrosion. Or for a wheel and tire the part # AM31994 for a 5 lug wheel and part # AM3S040 for a 4 lug.

  • Largest Trailer Rim Available with 4 Bolt Pattern
    Nothing we offer in the 15 inch rim size comes with a 4 bolt pattern. The largest diameter rim we have that will fit a 4 bolt pattern is a 13 inch rim like the # AM20224 that is a silver rim. The largest tire size would then be a 185/80-13 that would fit it like part # AM1ST79.

  • Can 175/80-13 Tires be Used to Replace 185/80-13 Tires in Emergency
    In an emergency situation you can use a ST175/80R13 tire like the Karrier ST175/80R13 Radial Trailer Tire # AM10210 if you have a blowout until you get to a repair shop to get the right size tire, but having different sized tires will lead to suspension problems if you do this permanently. We do have ST185/80-13 tires and wheels such as the Loadstar ST185/80D13 Bias Trailer Tire w/13" White Modular Wheel - 5 on 4-1/2 # AM3S333 and Loadstar ST185/80D13 Bias Trailer Tire with 13" Galvanized...

  • Can 13 Inch Trailer Tires and Wheels be Used in Place of 4.80-12 Tires and Wheels
    In terms of the space you have available between the fenders and the tire tread you could go to a 13 inch tire (there isn't a 4.80-13 so it would have to be an ST175/80R13). But the 13 inch tire will be 2.22 inches wider than what you have now meaning the tire inner sidewall will be 1.11 inches closer to the trailer. If you have more than 1.11 inches between the existing inner sidewall and the trailer frame/body then you can go with a 13 inch tire by also switching to 13 inch wheels. If...

  • Boat Trailer Tire Recommendation for Longer Distance Travel
    For traveling a distance you want to use radial tires, which are going to flex more than a bias tire and give you better traction and tread wear. You said you wanted a larger tire but also mentioned your bolt pattern, so I assume you want to replace both your wheels and tires; the 4-bolt pattern I assume is a 4 on 4" pattern, though if you are unsure please follow the link I've added to a help article detailing how to find your wheel's bolt pattern. The wheel I recommend taking a...

  • Best Tire for 1963 Aristocrat Lo-Liner Camper
    We can get this figured out! What you are looking for I believe is the 4 on 4" bolt pattern which is extremely common on the smaller 13" rims. I've included a FAQ article to show how to measure the bolt spacing. It is something that commonly gets confusing I could be wrong here but please double check. With that said your 1963 Aristocrat Lo-Liner Camper weighs in at about 1300 lbs. with out all your gear in there. Add another 500 lbs. of goodies and we get to about 1800 lbs. With...

  • Rim Recommendation with 4 Lug Bolt Pattern for Fitting Tire Size ST185/80-13
    Your tire size of ST185/80-13 that you have is designed to fit rim widths of between 4-1/2 and 5-1/2 inches so either width you mentioned would work fine. For a white wheel that will fit your tire size and has a 4 on 4 inch bolt pattern we have the part # AM20222DX or for a galvanized steel wheel we have the part # AM20224.

  • Recommendation on a 185/80D13 Tire and a 13 Inch Wheel the has a 4 on 4 Bolt Pattern
    I have a solution for you, but we do not have a tire and wheel combo in 185/80D13 with a 4 on 4 bolt pattern. However, we do have the Kenda Loadstar ST185/80D13 Trailer Tire, # AM1ST79, and the Dexstar Steel Trailer Wheel 13 x 4-1/2 Inches, # AM20222DX. The Kenda Tire is an 8-ply rated tire that has a weight capacity of 1,710 lbs a 65 psi. This tire is also speed rated at 81 mph and includes the 2 year warranty.
