Features to know about

Built for Everyday Hauling: 1,250-lb Capacity with DOT Compliance

This 12" x 4" Dexstar Steel Mini Mod Trailer Wheel handles the weight and demands of frequent towing. Rated for up to 1,250 lbs and meeting Department of Transportation specifications, it’s designed for consistent performance under load. The zero offset helps the wheel carry vertical weight evenly across the hub, giving you a confident setup for daily use or longer trips.

Clean, Durable, and Corrosion-Resistant: White Powder Coat over E-Coat Primer

You can count on this powder-coated steel wheel to look good and stay that way. The white powder coat finish is baked over an e-coat primer that shields the metal from moisture and road debris. It’s a straightforward design that resists rust and keeps its finish season after season.

Smooth, Balanced Design: Modular Steel Construction

The sturdy modular steel construction gives the wheel both strength and balance. It’s built to handle the flex and stress of highway speeds while maintaining a smooth ride feel. Each wheel is precisely made to meet DOT standards, so you know it’s been tested for the conditions real haulers face.

Simple Fitment Confidence: 5 on 4-1/2 Bolt Pattern, 0 Offset, 3.19" Pilot Diameter

The Dexstar Mini Mod makes matching your hub setup simple with a common 5 on 4-1/2" bolt pattern and standard 1/2"-20 wheel bolts. A zero offset centers the load right over the bearings, and the 3.19" pilot diameter provides straightforward compatibility with standard hub sizes. It’s a clean fit with no guesswork needed.

Determining Bolt Pattern

1. Count the lug holes

Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).

Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug

2a. For even lug counts (4-lug, 6-lug, 8-lug)

Measure from the center of one lug hole directly across to the center of the hole opposite it.

Center to Center
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"

2b. For odd lug counts (5-lug)

Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).

Center to Outside Edge
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Video Transcript for The Low-Down on the Dexstar Steel Mini Mod Trailer Wheel-AM20151

Today we're going to take a look at the Dexstar twelve inch by four inch white mini mod steel trailer wheel, with the five on four and half inch bolt pattern. This wheel is a sturdy steel construction, has a nice white powder coat finish over an e coat primer on the front and the back of the wheel. It gives you excellent corrosion resistance. This wheel is a modular design, or a mini mod design. Basically what that means, it's the one that has the round holes all the way around the wheel. This is a high quality wheel. It does meet the DOT, Department of Transportation's specifications.

This wheel is made by Dexstar. Dexstar is made in the USA. The few specs on this, we're going to measure the wheel. The diameter is twelve inches, which is measured inside to inside. If I take a tape measure, and if we go inside to inside, you can see right at twelve inch diameter the width is the same way inside to inside where the tire beads would seat.

Inside to inside is four inches, so twelve inches by four inches. This wheel does have a bolt pattern of five on four and a half inches, and if you go to measurable pattern on a wheel like this that's an odd number of lugs, in this case five, what you do is pick one of the holes. Let's say this one. Then you'll measure across to either one of these holes. The trick is when you measure it, it's from the center of the starting hole to the furthest edge of the hole that you measure to. If we go here to here, if we put a tape measure, I'll show you that center to outer edge, there we go, you can see is right at four and a half inches, so five on four and half inch bolt pattern. This does use a wheel lug size of a half inch by twenty.

Pilot hole diameter, it's the large hole here in the center of the wheel. It goes over the hub of your trailer. The diameter of that opening is going to be right at three point one nine inches. The weight capacity on the wheel is one thousand two hundred fifty pounds. That should do it on the review on the Dexstar twelve inch by four inch white mini mod steel trailer wheel, with the five on four and a half inch bolt pattern..

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.

thanks

Outstanding rim. I had to wait longer because it wasn't in stock but I'm glad I did. My spare rims match the original mini mods that were already on my Lowe's trailer.



by:

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



by:

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

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.



by:

Getting two of these was painful -- manufacturer changed the specs on the wheel. Elizabeth was AWESOME in that she kept me well informed as she worked with the manufacturer and eTrailers shipping to obtain 2 of the last of the old style wheels. Thank you Elizabeth for doggedly pursuing these wheels for me!! I'm your #1 fan!



by:

I wish I had found etrailer.com 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 etrailer.com.

THE CLINCHER:

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 etrailer.com, that the two combined, separate purchases were cheaper than anything else I priced for the same quality products.

THE HAPPY ENDING:

Had I known about etrailer.com 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 etrailer.com to anyone looking for similar services.



by:

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.



by:

Arrived quickly and Lauren provided excellent customer service!



by:

I specifically bought these because they are American made. I thought American made meant the quality level would be higher. I got white wheels for my pop-up camper but the paint is missing in a big area. Poor quality control. Not etrailer ault at all.

Trevor was excellent at helping
me to verify the correct part. I recommend this company, customer service was friendly and very helpful.
Thank you Brian

This product is an exact match and is providing excellent service.



by:

It's a white steel wheel. Nothing wrong with it and it does its job. I ordered it to match my existing wheels. It was a good price too.



by:

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.



by:

The original wheel I had for my trailer was damaged and I needed to replace it. It was convenient to see what I needed and have it shipped to me without leaving the house.



by:

Excellent overall experience dealing with etrailer.com, I found the product I needed at a good price, in stock and promptly processed my order. I will definitely use etrailer.com again when I need products for my trailer. Thanks Matt.

  • What Valve Stems and Wheel Center Caps will Go with the Dexstar Steel Mini Mod Trailer Wheel?
    Hello Steven, You are correct. The Dexstar Steel Mini Mod Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - White Powder Coat # AM20151 does not come with the valve stem or cap. Here are 2 different options for a valve stem: - Americana Metal, Bolt-In Valve Stem - 1-1/4" Long # AM20906, this is a heavy duty valve stem that can handle over 100 psi - Americana High Pressure Rubber Snap-In Valve Stem - 1-1/2" Long # AM20904, still pretty heavy duty, up to 80 psi For a Cap you can go with either...

  • 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...

  • 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. If you have a 3500lb or larger axle you will need to change out your axles...

  • Can Larger Wheel Or Tire Be Used On 1989 Coleman Columbia Pop Up Camper
    You can go to a larger wheel or tire on your stock axle as long as the wheel matches the current bolt pattern and you have enough clearance with the larger size. 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...

  • 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 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 # LHHA315 which is a silver powder coated modular wheel like the wheel you'd looked at.

  • Does a 5.30x12 Trailer Tire and ST145/R12 Trailer Tire Use the Same Size Wheel
    A 5.30x12 tire like the one in the Kenda 5.30-12 Bias Trailer Tire with 12" White Wheel - 5 on 4-1/2 - Load Range B # AM30740 combo and an ST145/R12 like the Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12" White Spoke Wheel - 5 on 4-1/2 - LR D # AM31199DX both use 12" x 4" wheels. You could use one of those combos, re-use your old wheels or get some new ones like the Dexstar Steel Mini Mod Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - White Powder Coat # AM20151.

  • Are There 4.80R12 Tires With Powder Coated Wheels Available
    We don't currently offer a 4.80R12 radial tire and 5 on 4.5 wheel together, but we do offer them separately with part # TT48012C and # AM20151. This wheel has a white powder coating, if you'd prefer silver or black then you can click on the link below that will take you to our available options.

    Though we do not have a ST145R12 Tire on a white modular wheel, we do have The Kenda Karrier S-Trail ST145/R12 Radial Tire w/ 12 inch Galvanized Spoke Wheel # AM31202. 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. The tire has a Load Range D with a ply rating of 8 and has a maximum load up to 1,220 pounds at 65 psi. The tire has a maximum speed of 65 mph. You can separate the combo and...

  • Comparing the Dexstar Steel Spoke and Dexstar Steel Mini Mod 12 Inch Trailer Wheels
    The only difference between the Dexstar Steel Spoke Trailer Wheel part # AM20132 and the Dexstar Steel Mini Mod Trailer Wheel part # AM20151 is the style. The Spoke style refers to the triangular shaped cutouts whereas the Mod style refers to the circular shaped cutouts. They both have a 1,250 lb weight capacity and 3.19" pilot diameter.

  • Can a 145R12 Tire and Wheel Be Ordered with White Rim

    That particular tire size, the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range E Item # AM10140, is only sold separately and unmounted. This gives you a wide range of wheel choices. Since you said, not aluminum, take a look at the Dexstar Steel Mini Mod Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - White Powder Coat # AM20151 this is a just one choice of many. All the 12 inch steel wheels like # AM20132 are limited to 1250 lbs capacity so you won't get the full load capacity...

  • 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.

    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. We have no pilot holes that are 2.75 or 2.8 inches in diameter but we do have the -Taskmaster Steel Modular Trailer Wheel - Silver # TA79RR with pilot 2.95 inches I've linked the page to your other...

  • What Rims Should Be Used for 4.80-12 Tires
    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...
