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"

Dexstar Steel Mini Mod Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - White Powder Coat - AM20151

Average Customer Rating:  4.8 out of 5 stars   (1665 Customer Reviews)

White power coated, 12" steel wheel features a 5 on 4-1/2 bolt pattern and meets Department of Transportation standards.


I ordered a rim the would match my other tire on my trailer. The picture on the advertisement shows 8 holes around the perimeter of the rim. The rim I was sent had 10 holes around the perimeter. I called etrailer and explained that I did not get the rim that was pictured in the advertisement (8 hole). They said they would send me the correct rim as pictured in the advertisement with instructions on how to return the 10 hole rim. It has now been over 2 weeks and I have not heard anything or received anything. I guess I will have to call again and try to hash this out. Picture of 10 hole rim included.


Excellent powder coating.


just what I needed to replace my spare.


I found this rim quickly on etrailer that matches a ruined one. Found the product I needed at a price I liked and it arrived quickly to my surprise. I recommend this product and I recommend using etrailer for all your trailer needs!!!

I have been using this rim on my boat trailer for almost a year and absolutely zero problems. The paint has held up and no leaks.
Randy V - 03/04/2020


I wish I had found sooner. I was looking for wheels and tires for a boat trailer I purchased, knowing it was in need of both. I bought the tires at a retail store and decided to look for the wheels in the same way, soon realizing they would have to be ordered and delivered to a store anyway, I went on line and found


I ordered the wheels on a Sunday and received them the following Wednesday, (sooner than I could have gotten them anywhere else without paying special two-day freight service). I still saved enough money buying the wheels from, that the two combined, separate purchases were cheaper than anything else I priced for the same quality products.


Had I known about and bought them together, mounted and ready to use in the first place, I would've saved even more. That is an even cheaper way to get them, it turns out.

I would definitely recommend to anyone looking for similar services.


Ordered 2 trailer rims for boat trailer. I was notified after a couple of days they had not received them in to their warehouse yet. i was notified quickly with alternate choice that I could choose from that they had in stock which they provided me so i didn't have to go searching . I chose one that was in stock and received them very quickly. their customer service and pricing is excellent! My husband could not believe the service, quality and price. We will be using them again.


Great wheel at a great price. One wheel came damaged however the customer service was excellent. etrailer was quick to send me a replacement.


I my order was taken by George J. He did a great job explaining to me the shipping process, the wheels look to be just what I was looking far, Plus I got them 2 days earlier than I thought I would. I haven't mounted them yet but I'm sure they will work out well. Very good people to buy from.
Thank You


Delivery was fast. Product good. But like everything else the price has gone up since we last bought them. But overall etrailer is great to deal with


I ordered 2 tires and a wheel on a Monday, received them on Thursday...amazing, and the order was correct. great product, great price and lightning fast shipping, and I get to go to the lake on time.



The product you deliverd was good quality. Bolted right on with no issues

  • Comparing the Dexstar Steel Spoke and Dexstar Steel Mini Mod 12 Inch Trailer Wheels

  • Smallest Compatible Wheel for 12 Inch Brake Hub/Drum
    A 14-1/2 inch wheel is the smallest diameter wheel that will work with a 12 inch brake drum. If you try to go smaller, the drum won't fit into the wheel far enough for the wheel studs to go through the wheel. If you're needing a wheel with a 5 on 4-1/2 inch bolt pattern like the # AM20151 you'd looked at, you'll need to go with a 15 inch wheel like # LHHA303 which is a white powder coated modular wheel like the wheel you'd looked at.

  • Can Kenda Karrier S-Trail ST145R12 AM10140 Be Mounted On Standard Trailer Wheel Then Shipped?
    You can order a standard trailer wheel like the # AM20151 with the common 5 on 4-1/2" bolt pattern or the # AM20122 with the 4 on 4" bolt pattern and have a local tire shop mount the Kenda Karrier S-Trail ST145R12 # AM10140 to the wheel for you. We do not have the equipment to do the mounting ourselves. The combinations we offer are shipped to us that way from the manufacturer. I included videos of the products mentioned for you to take a look at.

  • 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.

    When it comes to something similar to the Kenda Karrier ST145/R12 Radial Trailer Tire with 12" Black Mod Wheel, # AM35354, we do offer the Americana Steel Mini Mod Trailer Wheel, # AM20151, which is a steel wheel with a white powder coated finish and the Karrier S-Trail ST145/R12 Radial Trailer Tire, # AM10140. This are sold individually so I recommend taking them to your local tire shop for mounting.

  • Recommended Tire for Steel Mini Mod Trailer Wheel with 13
    The tire size you reference, size 5.30 x 12, is compatible with a 12" x 4" rim. The wheel I recommend is Steel Mini Mod Trailer Wheel, # AM20151, as long as your trailer uses wheels with a 5 on 4-1/2 bolt pattern, I have included a FAQ article on determining your wheel's bolt pattern. If you find you have a 4 on 4 bolt pattern you can go with # AM20140. The rim you referenced, # AM20253, is 13" x 4-1/2". I have included a couple of FAQ articles on tires for you to check out too.

  • Valve Stem Size For Trailer Wheel # AM20151
    The correct valve stem for the trailer wheel part # AM20151 that you referenced is the part # AM20904 which fits rim hole diameters of .453 inch. This will work great with the Kenda K371 Bias Trailer Tire part # AM10004 that you referenced as well.

  • Smallest 13 Inch Trailer Tire
    I have another option but the smallest 13 inch tire that we offer is a 175/80/13 like the Kenda Karrier # AM10210. The only option to get a smaller tire would be to go to a 12 inch tire like the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range D # AM10130 which will be about 3 inches shorter and 1 inch narrower than a 175/80/13 tire but will have a lower maximum load rating of 1220lbs at 65 psi.

This tire and wheel combo has a galvanized wheel which will provide a superior protection from rust and corrosion way better then a white wheel.

  • Smallest Wheel and Tire Setup to Fit 10 inch Brake Hub on Trailer
    13 inch trailer wheels are the smallest you can go to fit over a 10 inch hub and drum. The smallest tire size to fit that rim would be a 175/80-13 so for that size on a wheel that would bolt up to your trailer you would want the # TTWA13RWS. Overall diameter is 24.02 inches.

    We do have many 12x4 inch wheels with the 5 on 4-1/2 inch bolt pattern. The center pilot hole you referenced is and interesting question because trailer wheels are not centered on the hub so the size of that hole isn't as important as the bolt pattern that helps center the wheel on the hub.

  • Recommended Trailer Tire/Wheel For Highway Speeds For 4.80 x 12 Tires With 5 bolts
    We have exactly the tires and wheels you are looking for in a Taskmaster brand except they do not come mounted to the wheel. For your tire I recommend the Taskmaster 4.80-12 Trailer Tire - Load Range C # TTWSF48012C. This Taskmaster tire is a bias tire with 990-lb maximum load at 90 psi. It is an ideal tire for a utility trailer like yours and has a maximum speed capacity of 81 mph. It works well on most road surfaces and can handle off-road/rougher situations when needed. For...

  • Trailer Wheel Recommendation for Tritron 2017 Jet Ski Trailer
    The closest option we have to what your trailer has would be the part # AM30670 which has 8 triangular shaped holes in the wheel. We also have the same pattern you referenced in white instead of gray # AM20151. If you need a tire for these, I recommend the Taskmaster 4.80R12 Radial Trailer Tire - Load Range C Item # TT48012C. These are great tires with a speed rating of 81 miles per hour. You could have them mounted at a local shop.

  • High Speed Replacement 4.80-12 Replacement Tire and Wheel With 5 on 4-1/2 Bolt Pattern
    You could do the Kenda # AM30660 and safely pull at 65 mph. This is our only option for a pre-mounted tire and wheel combo. I strongly recommend going with a tire with a higher speed rating, but to do this they will not come mounted on the wheel. You would buy them separately and have them mounted at a local shop when they arrive. For your tire, I suggest the Taskmaster 4.80-12 Bias Trailer Tire 12" load range C # TT48012C because these tires are rated for 81 mph. Then for your wheels...

    You'll want to mount a 4.80-12 tire like the Taskmaster # TT48012C tire on a 12 x 4 rim. I've linked to our selection of 12 x 4 rims, you'll want to be sure to choose a wheel that's compatible with the bolt pattern your hubs used, either 4 on 4 or 5 on 4-1/2. If you're just wanting something basic, for a 4 lug I'd recommend # AM20140 or # AM20151 for a 5 lug. If you're looking for for a nicer aluminum wheel, go with the HWT # AM22318HWT for a 4 lug or # AM22319HWT for a 5 lug. I've...

  • Is Larger Load Range Tire Okay for 1992 Coleman Trailer
    Yes, you can use a larger load range tire, like a load range E tire on your 1992 Coleman trailer, so long as the tire fits your current wheel and you have enough clearance (3" from the top of the tire to the fender and 1" from the inside of the tire to your frame rail). For example, if you have 12" wheels and your trailer uses ST145/12 tires, you can swap to the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range E # AM10140. If you don't have 12" wheels you will also need...

It looks like you have something like a 205/65-10 tire similar to the # AM1HP50 with a 4 on 4 bolt pattern right now so we will use this as an example. The # AM1HP50 has an outer diameter of 20.8" and an 8.3" section width. This has a large section width so the inside clearance probably wont' be a problem and you will want to...
