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"

showing rust already.. salt exposure minimal ... less than 20 total days and always washed carefully after each use ... trailer stored in garage between uses




These are a great product. The quality of the galvanization is better than I expected. These will work well for my application.


Excellent customer service. Exactly how described. Very fast shipping.



Excellent product


Nice wheel. Two things from being 5 star. One, it would be good if they buffed it out after the zinc platting (galvanizing process). There are a few rough spots where the tire needs to seal. Second, the add indicates that there is a valve stem included with the wheel. I wasn't. As a suggestion, it would be good to make it easier to find the weight capacity and match it to the tire capacity. For example, If this wheel is only rated for up to a load range D tire, then say so in the specs. Not a big issue but this would make it easier to match wheels and tires. I was using this with load range E tires I already had, but the wheel, based on the weight numbers is really only a D.



Just fine. No issues at all.


Better than the stock wheel! Perfectly balanced. Great price.


Always fast delivery. Great service. I love ordering from this company





I recieved a four lug wheel instead of the 5 on 4.5 lug wheel that I ordered. I now have a wheel that is useless to me and not to mention the lost time that this has caused. I am very disappointed. Please rectify this issue immediately.

I apologize for any inconvenience that this has caused you. I see that our customer service department has sent you the correct wheels. We would appreciate updated information on the wheels after you receive it.


Arrived quick and tire mounted fine. Using it for a spare boat trailer tire. Have not had to put it on the trailer yet.


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.)

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



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.


I purchased 2 galvanized wheels and 2 galvanized hubs. The box they shipped the items in was sealed well with staples and was robust, but the items weren't separate well at all. Whomever packaged the order placed a few pieces of packing paper inside. All the items were tossed around and dinged up. The threaded wheel lugs on the hub were dented and needed to be filed and thread chased. Other than that, the products seem nice, but time will tell.


I did get the wheel balanced when I had the tire mounted (which is an extra expense). But I drove 5,000 miles mostly over 70 mph and they were great.


Be careful ordering tires and rims from this company, I received my order as three separate pieces, the tire was not mounted to the rim. If there was a place to specify that I wanted them pre-mounted it was not easy to find on their website. Next time I am going to my local [farm store].

Thank you for your review. We do not mount any tires but we do have options available that come pre-mounted. I have attached some of your size:


Each of the three 12×4 galvanized wheels that I ordered and received was in deplorable condition. The galvanized process left a mess of excess material on the wheel. Each wheel appeared as if it had melted in the same spot. Very disappointed in the lack of workmanship and quality control.

Etrailer Expert

Jenny N.


I will have our customer service team reach out to you. The manufacturer dips the wheels in a galvanizing solution and allows the wheels to drip dry. The finish of the wheels will be a rough finish versus a smooth one.


Galvanized rim for trailer spare. We live near salt water, and I only buy galvanized rims. Had to buy the tire, valve stem, and rim separately as this size radial tire is not sold as a combo-package, only sell bias ply tires on painted rims as combo package. If there was an option to have etrailer mount the tire, I didn’t see it. Fortunately, some of us old guys still know how to put a tire on a rim. The tire, rim & high pressure valve stem are all excellent quality (you always have to smooth the galvanized “barnacles” on a new rim in the seal area). Shipping & delivery was fast, and the tire mounted and inflated easily.


Always a pleasure doing business with etrailer. Good prices on good products and shipped fast.


I ordered this wheel to use on a utility trailer. It looks great and the tire mounted great as well. Pricing was good and delivery was timely and to my front door.


Top quality tire rim / part - always pleased with the super customer service I receive from etrailer; Thanks - Josh. etrailer is always my go to store for trailer parts - I don't even need to save it as a web Favorite - it already is!


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.


The wheels arrived and are the brightest galvanized wheels I've seen, better than expected. The ordering and shipping were simple and all arrived a day early. Can't beat that at any price!


Excellent service, great product. And a great price. I will definitely be buying from this company again.


Both the tires and rim I ordered was as I expected! they arrived promptly they are all ready on my trailer!!


Great customer service. UPS had problems with my delivery and retailer was quick to replace my order. Very pleased!!!


Great rim for a jet ski trailer. It's holding up to the saltwater well.


I got 1 wrong rim and sent 3 emails with no response

  • Lug Seat Angle of Dexstar Galvanized Steel Spoke Trailer Wheel # AM20134

  • 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 # AM20134,...

  • What 12 5-Lug Replacement Aluminum Wheels do You Recommend for My Trailer?
    I have an answer for you. There are many different 5-lug bolt patterns for trailer wheels. For example, there are 5 on 4-1/2, 5 on 4-3/4, 5 on 5, and 5 on 5-1/2. The 5 on 4-1/2 is the most common pattern. In order to know for sure what bolt pattern you have, I recommend measuring your wheels to confirm the pattern. I went ahead and attached a helpful FAQ article to help you with this process. I also attached a template you can print off to use. With that being said, we only carry replacement...

  • Smaller Tire & Wheel For 13 Scamp Trailer to Move Into Garage
    So it is actually the hub that determines the wheel fit, so I did some research on your 13' Scamp trailer and found it has a 2,200 lb axle. Hubs for that size axle do fit 12 inch wheels, so you can absolutely use a 12 inch wheel like the Steel Spoke Trailer Wheel # AM20134. It will fit right on your hub, but with that said, your current 13 inch tires won't fit that wheel, so you will need a wheel and tire combo. Your Scamp uses 175/80R13 size tires, which measure 24" in diameter, and to...

  • 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.

  • Recommended Trailer Wheel With 3.19 Diameter Hub Bore
    I have another option for you, but we do not have a 10" diameter wheel that has the 5 on 4-1/2" bolt pattern and a pilot hole of 3.19". The two 10" wheels that we offer with the 5 on 4-1/2" bolt pattern both have a 2.80" diameter pilot hole, and a 3.19" diameter hub bore is not standard with this size wheel. As long as the center of your hub is 2.80" or smaller you would have no issue using the Steel Trailer Wheel - 10" x 6" Rim - 5 on 4-1/2 - White # AM20046, as trailer wheels center...

  • 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.

  • Replacement 12 Inch Wheel Recommendation for Jet Ski Trailer
    For your application it sounds like you need a 12" wheel with the standard 5on 4-1/2" bolt pattern. Since this is for a water trailer I recommend using a wheel with either a galvanized finish like the Americana # AM20134 or with an aluminum construction like what we find with the HWT Series S5 # AM22319HWT as these will resist water corrosion much better than the standard steel wheels. Attached are review videos of both wheels, our selection of 12" wheels with that 5 on 4-1/2" bolt pattern,...

  • Trailer Wheel and Tire to Replace 4.80-12 that has Higher Speed Rating with 5 Lug Bolt Pattern
    For a wheel and tire that you can use in place of your 4.80-12 tire that has a higher 81 mph speed rating you'd want the Kenda S-Trail part # AM31199DX which has a tire size of 145/R12 which is very close to what you have now so it would fit without interference but like I said has the higher speed rating. Then for a wheel you'd want the # AM20134.

  • 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...

The Aluminum Lynx Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - Silver # LH45FR also has the zero offset, so there is no difference between the two wheels in how far they sit from the axle hub face.

If you're okay with that you can use the following: - Taskmaster 4.80R12 Radial Trailer Tire - Load Range C # TT48012C - Steel Spoke Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - Galvanized Finish # AM20134 The wheel does come with the valve stem so you do not have to purchase that separately.

  • Taskmaster 5.30R-12 Spare Tire With a Galvanized Steel Wheel 5 On 4-1/2" Lug Pattern
    Your trailer hubs are most likely lug centric and not hub centric. If you have tapered lug nuts that hold on your wheels then you have a lug centric hub and the pilot hole diameter will be okay being larger. Mixing your load range should not be an issue since you are going larger. The higher load rating will have a stiffer construction that will cause the tire to bounce more than absorb on bumps. As this is for a spare tire you will not be using it for long periods of time. You can...
