Features to know about

Built to Handle Real Loads: 1,660-lb Capacity with 0 Offset

When you’re hauling boats, campers, or cargo, you want a wheel that’s built to take the weight. The Dexstar Steel Mini Mod Trailer Wheel measures 13" x 4-1/2" and carries a 1,660-lb rating. Its 0 offset keeps the load evenly distributed across the hub for stable, predictable handling whether you’re towing across town or down the highway.

Fights Rust and Corrosion: Black Powder-Coated Steel Finish

Moisture, salt, and grime don’t stand a chance. This steel wheel is protected by a two-step e-coat primer and black powder coat finish that resists corrosion and keeps it looking sharp. It’s a practical upgrade that holds up season after season in humid or coastal environments.

Reliable Fitment Every Time: 4 on 4" Bolt Pattern and 2.65" Pilot

Finding the right wheel doesn’t have to be guesswork. This model uses a 4 on 4" bolt pattern with 1/2"-20 wheel bolts and a 2.65" pilot diameter for straightforward mounting. The consistent sizing gives you confidence that your setup will bolt together cleanly and run true.

Built for Smooth Road Performance: Balanced Steel Design

The modular steel design gives this wheel strength without extra weight, helping it stay balanced on long hauls. With its DOT compliance and even load distribution across multiple wheels, it delivers the kind of highway stability that makes towing feel easy mile after mile.

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"

great great product. just what I was looking for, great shipping and delivery.



by:

About a year ago I ordered three Dexstar mini mod wheels,two new hub and bearing kits,U bolts,spring shackles, greaseable shackle bolts and spring eye bushings. I havent put many miles on the trailer with these new parts but so far they have performed as expected, the trailer pulls much easier and smoother. And working with etrailer was very easy.

Showed up earlier than expected, discount tire mounted and balanced for free. Wheel looks great, hopefully I don’t need the spare anytime soon. Thank you for the quick order delivery

  • Is There A 185/80R13 Tire Mounted On A 13" Rim With The 4 On 4 Bolt Pattern?
    Hi Rob! We definitely have 13" wheels with the 4 on 4 bolt pattern and 185/80R13 tires, but we do not have any already mounted, unfortunately. The 4 on 4 bolt pattern isn't super popular with the 13" wheels for some reason, so you will need to have a tire mounted after purchasing a tire and wheel separately. For the tire, if you don't have one picked out already, the Karrier ST185/80R13 # KE68KV is a great choice. This is an 8 ply radial tire, has a Load Range D (1,709 lbs at 65 psi),...

  • Will The Dexstar Steel Mini Mod Trailer Wheel AM20242 Work With A 175/80-13 Tire?
    Hello Rodd, thanks for reaching out. It sure will! The Dexstar Steel Mini Mod Trailer Wheel # AM20242 will work with really any 13" trailer tire. A 175/80-13 will work just fine. What kind of trailer is it going on?

  • Tallest Tire Available For The 13" Dexstar Steel Mini Mod Trailer Wheel AM20242
    Hi James! The largest aspect ratio (tallest) tire you can put on the Dexstar Steel Mini Mod Trailer Wheel - 13" x 4-1/2" Rim - 4 on 4 - Black # AM20242 will have an aspect ratio of 80. So the largest tire we have for this wheel is the Kenda Loadstar ST185/80D13 Bias Trailer Tire - Load Range D # AM1ST79 for a bias tire, or the Kenda Karrier ST185/80R13 Radial Trailer Tire - Load Range D # KE68KV for a radial. Keep in mind the wheel does not include a valve stem, so you will also want to...

  • Will the Dexstar AM20242 13 Inch Wheel Fit a 12 Inch Trailer Hub?
    Hi George! Yes, the Dexstar Steel Mini Mod Trailer Wheel, Part # AM20242, can fit a 12 inch hub, but the hub size itself isn't what determines whether the wheel will fit. The important thing is that your hub has a 4 on 4 bolt pattern, since that's what this wheel is designed for. If you're not sure what bolt pattern you have, it's easy to check. On a 4 lug hub, simply measure from the center of one wheel stud straight across to the center of the stud directly opposite it. If that measurement...

  • Are there 15" Wheels that Have a 4 on 4 Lug Nut Pattern?
    No, I am sorry Randall. There are no wheels available that you can drill your own lug nut holes. The largest wheel we have in a 4 on 4 lug pattern is a 13" wheel like the Dexstar Steel Mini Mod Trailer Wheel item # AM20242. This wheel measures 13" diameter x 4-1/2" wide and has a 1,660 lbs capacity. Another option is to swap out your trailer's hubs to ones with a more common lug nut pattern so you can use a larger wheel. To do this I would need to know what size bearings are in your current...

  • How is 4 Lug Bolt Pattern of Trailer Wheel Measured
    Hey Robert, what you will be able to use as a spare is the part # AM3S130 which is the same tire size as what you have and also has the only 4 bolt pattern a trailer wheel will have nowadays. But to answer your question you would measure from the center of one lug nut to the center of the lug nut opposite of it and it should measure 4 inches. See attached picture.

  • Looking for Replacement 13 inch Trailer Wheel that Could Fit 2011 Tahoe Q7i Trailer
    Hey Ronnie, I attached a link to a page that has all of the 13 inch trailer wheels we offer down below. Basically it will come down to whether or not you have a 4 lug or a 5 lug bolt pattern as to what will fit. If you have a 4 lug wheel you'd want the part # AM20242 or if it's 5 lug you'd want the part # AM20245.

    Hey, Zach! After looking at the wheels we have in black and checking to see if we had what you're looking for and I do have an option, but it may not be 100% what you want. I saw that you were looking at wheel part # AM20214 which would let you use the Americana Baby Moon Trailer Wheel Center Cap - Chrome-Plated Steel part # AM90086. We don't offer anything like this with a 4 on 4 bolt pattern. However, what we do have is wheel part # AM20242 and you can use the Americana trailer wheel...

  • Should I Stay With 13" Wheels Or Upgrade To 14 Wheels?
    I will start by sating that the wheels/tires on the trailer you are looking at do look kind of undersized. So you definitely can stay with a 13" set up like the Kenda Karrier ST185/80R13 Radial Trailer Tire - Load Range D # AM10208 and Dexstar Steel Mini Mod Trailer Wheel - 13" x 4-1/2" Rim - 4 on 4 # AM20242, which will give you 1,660 pounds of capacity (the wheel is rated lower than the tire in this case). However, you need to have at least 3" of space from the top of the tire to the...

  • Replacement Brake Magnet and Tire/Wheel Combo for a 1964 Shasta Compact Camper
    I am guessing that your axle weight rating is either 2,000 lbs or 3,500 lbs. You should be able to verify this by looking at the tag/sticker near the trailer tongue or by finding the weight rating stamped in the middle of the axle. We do have replacement brake magnets for each. Simply check to see if you have 7" brake assemblies or 10" assemblies and then use part # AKBRKR-M7 or # AKBRKR-M10 respectively. Since the wheel in your picture has a 4 on 4" bolt pattern I am guessing that you...

This bolt pattern and size does not have a hub cap that will fit but they look really nice with chrome lugs like # 12CLN.

  • Largest 4 on 4 Wheels and Tires to Fit a 1972 Hunter Compact Trailer
    The largest diameter wheel we carry with a 4 on 4 bolt pattern is a 13 inch wheel. The largest tire for a 13 inch wheel is an ST185/80-13 tire, part # AM1ST79, which you can then put on a 13 by 4-1/2 inch wheel, part # AM20242. It has an outer diameter of 24.4 inches and is 7.2 inches wide. The only catch here is this is a bias tire, which might be great if you'll be towing on rough roads a lot of the time. If you're primarily going to be on highways I recommend going with a radial tire...

    The Karrier ST175/80R13 Radial Trailer Tire - Load Range D # AM10210 fits a 13" wheel with 4-1/2", 5", and 5-1/2" widths. Although there is no wheel and tire combination that comes with a 4 on 4 bolt pattern, we do have wheels available for these tires. The closest we have to a 2.5" center hole is a 2.65" center hole with the Dexstar Steel Trailer Wheel # AM20242 or # AM20222DX.

    100 mm in inches is 3.9 inches which means your bolt pattern is pretty close to 4 on 4 inch but since it's German it very well could be a totally different bolt pattern than what we carry. If it is 4 on 3.9 inch we aren't going to have a replacement. If it is 4 on 4 inch then I'd recommend the part # AM20242 which is a 13 inch diameter wheel with that bolt pattern.
