Features to know about

Built to Take on Wet and Salty Conditions: Galvanized Steel Construction

This 12" x 4" steel wheel is made to handle moisture and road grime without rusting out. The galvanized finish provides superior protection from corrosion, making it a great option where water exposure is part of the job. You get lasting durability from sturdy steel construction with an 8-spoke pattern that meets Department of Transportation standards.

Confident Support Under Load: 1,250-lb Capacity with 0 Offset

When you’re hauling gear or equipment, capacity matters. This wheel carries up to 1,250 lbs and uses a 0 offset to keep the load centered over the hub for balanced support. It’s built to handle everyday use with the right mix of strength and reliability in a 12" steel rim design.

Straightforward Fitment for Hassle-Free Setup: 4 on 4" Bolt Pattern with 2.84" Pilot Diameter

Getting the fit right is simple with clear specs. This wheel uses a common 4 on 4" bolt pattern, a 2.84" pilot diameter, and a wheel bolt size of 1/2"-20. The even bolt layout means easy alignment on compatible hubs, so mounting stays quick and worry-free.

Balanced Design for Smooth Rolling: Lug-Centric Mounting and Solid Wheel Weight

At 9 lbs, this wheel has enough heft to stay stable on the road without adding unnecessary weight. It’s lug centric, so alignment is guided by the lugs rather than the hub—perfect when you need consistent tightening and balanced rotation.

Ready for Real-World Use: DOT-Compliant with a Limited 2-Year Warranty

This galvanized steel spoke wheel meets all DOT specifications for safety and performance. Backed by a limited 2-year warranty, it’s built for dependable service mile after mile while keeping maintenance low and confidence high.

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 Steel Spoke Trailer Wheel Spec Review

Jeff: Hello everybody. This is Jeff at etrailer.com. Today we're going to take a look at this Americana 12" by 4" galvanized steel spoke trailer wheel with the four on four inch bolt pattern. Now this is a steel wheel. It is the eight spoke design and it is a galvanized finish which provides superior protection from rust and corrosion. The galvanized finish wheels like this one are mainly used in marine applications where you're going to be around water.

If you notice, it does include the valve stem is all installed. This wheel does meet the DOT, Department of Transportation, specifications. A few specs on this, we're going to measure the diameter and the width. The diameter of the wheel is 12" and that's always measured inside to inside. So if we get our tape measure and if we go straight across there, as you can see, 12" diameter.

The width on the wheel is also measured inside to inside or bead seat to bead seat. It's right at 4" wide.Now the bolt pattern on this wheel, you can see, is a four lug. It's a four on four inch bolt pattern and if you want to measure that on a wheel, that's an even number of lugs, like in this case, four. It's pretty easy because the lug holes are right across from each other. So you just pick whatever lug hole you want, measure from the center of this hole directly across to the center of the one right across from it.

It'll measure 4". So this is a four on four inch bolt pattern. The wheel lug size that this uses is a half inch by 20. The weight capacity on this wheel is 1,250 pounds and the last measurement is the pilot hole diameter, which is the large hole here in the center of the wheel, goes over the hub on your trailer. Diameter of this opening is 2.84".

But that should do it for the review on the Americana 12" by 4" galvanized steel spoke trailer wheel with the four on four inch bolt pattern.

Still round and rolling smoothly down the road.

Good quality at a good price. I have tow others on a small trailer, and they have weathered well, no issues withe galv coating etc.



by:

No air valve included. Post surgery trying to get ready. You gave me a whole bunch of extra work.



by:

Arrived on time perfect condition.
works perfect and looks great for my boat trailer .
thank you
great product



by:

Super FAST shipping, product BETTER than advertised!! EASY transaction. Will order from again. Thank You!!



by:

Exactly what I was looking for, exactly as pictured. Super fast shipping!



by:

Just as described, just what I needed. Great company to deal with! Fast shipping, too.



by:

Very nice wheel..
I only wished it had
valve stems,
But no big deal...
Thank you!



by:

People need to read the bad reviews as well. Some of the reviews said the wheels were crap. I thought with the bad reviews, something would have been done about the blemished wheels. I was wrong. My wheels were very disappointing to me. They looked like they covered up rust or something like it. I'm so disappointed in the product, especially after watching your video. Sorry to say "fool me once" I can't see using etrailer ever again.



by:

These wheels still looks like new after 3500 miles of use. Great seal on the bead and valve stem.



by:

Just received this rim for a replacement on my boat trailer. Old one got ruined. very quick turn around time from order to delivery. Haven't mounted a tire on it yet but the rim looks to be very good quality.



by:

FAST DELIVERY: I ordered online late Sunday afternoon; these were delivered to my porch in West Texas on Wednesday. (I've ordered from eTrailer a few times over the years; same good experience each time.)

I had tried painting my old white wheels; the paint did not stick well, so I threw up my hands and ordered these, which I had previously considered.

APPEARANCE: Now, these are not chrome; they are galvanized and therefore have every right to look like your grandmother's galvanized wash tub. But these (I ordered three) look very much like the photo, which to me appears to be a semi-gloss, slightly uneven chromed look. So these wheels do, at casual glance, appear to have been chrome plated; on closer inspection, the galvanized irregularity is visible, a mildly waxy sheen or such.

My white painted wheels lasted 20+ years, then became a bit rusty; I expect these to last much longer.



by:

Galvanized 12 inch trailer rims arrived very fast. 1 rim had small bent spot/ding that did not affect tire seating ability. Galvanizing was very good. Overall quality was very good. Mounted Taskmaster 4.80R12 Radial tires, which are speed rated to 81 mph. I depend on etrailer for my small boat trailer wheels and tires. I tow this small trailer about 15,000 miles a year, so need quality and service. Thanks etrailer.



by:

I had a couple of issues with the wheels with the first being, there was some roughness in the galvanized finish so that one of the tires would not bead properly until the unevenness was sanded down.

The second was that while the galvanized finish on the back of the wheel was nice and constant, the front of the wheel had an uneven finish and was kind of blotchy. Bummed I couldn't flip the wheel, but living with it.



by:

The finish on this wheel was pretty rough. It appeared to have curb rash on the circumference and there were paint flakes in the lug nut/ valve stem holes. It’s hard to tell if this was a brand new wheel with a horrible paint job that also dripped down all on one side or if it was welded and refurbished and then sold as new. The tire mounted OK, with no apparent leaks so far. I guess it will be OK for my Harbor Freight light utility trailer, unless it starts leaking or it comes apart some how.

During the galvanization process the wheels are dipped into the solution and then are drip dried. Which means that it can allow for a rougher finish, and is probably why it is is looking dripped more on one side than the other.



by:

Exactly what I was looking for. Got the tires mounted on the rims last week and gonna get them on the trailer today.



by:

I received exactly what I ordered and very quickly! The tires and wheels still look great



by:

Usually purchase in person, then it's what you see is what you get. Online it's what you don't see... these tires are (DATE STAMPED) week 37 of 2023 and considered old stock sold as new! Galvanized wheels have globs of coating size or a quarter, other than these major issues that I emailed to @ ETRAILER without response, good things: very fast delivery, as my trailers wheels and tires were stolen preventing planned trip! Oh yea...packaged very good with extra protection. No reason for pics or videos, my statement is not the first,,,



by:

I had both wheels installed this afternoon after receiving the package arrived as scheduled. They look great. See attachments. L.p.pI can't wait to haul stuff with these new sets of wheels on my utility trailer. Great products with excellent service. For sure, i will continue to purchase stuff from etrailer. Thank you.



by:

I recently purchased a galvanize rim four on four for my trailer I bought the rim to use as a spare but I like the way it looks on the trailer so I'm going to get one for the other side. I will use my black rim as a spare.



by:

I bought a pair of these wheels to replace the existing rusty painted wheels on my boat trailer- nice improvement! Here are before and after pictures.



by:

Quick shipping from etrailer, but I wish I had noticed that these don't come with valve stems before I ordered. I got the high-pressure stems from them soon enough though. Like others have said about these, they look shinier in the pics then they really are. Some of the welds were a bit rough, and the finish wasn't perfect, but a liberal amount of elbow grease got them looking great. Huge improvement from the ugly old wheels I had.
So far I'm happy. We'll see how they look after some use.

  • What 4.80-12 Tire on Galvanized Wheel do You have for My Boat Trailer Used on Sometimes Saltwater?
    Hello Todd, We definitely have something for you, but we do not a radial tire and wheel combo, as we only have that tire and wheel combo in a bias. It depends on your bolt pattern, and the weight of your boat to decide what the best option for you. You will want one of the following: - If you have a 5 on 4 1/2" bolt pattern and your boat does not weigh more than 2,500 pounds (assuming you need 2 wheels) # AM30670 - If you have a 4 on 4" bolt pattern and your boat does not weigh more...

  • How to Choose Correct Replacement 12 Inch Wheel For Boat Trailer
    Hi Alexander, I can help you figure out a replacement, but we have no way of knowing what wheel is on any specific trailer, and can't do anything with a VIN (as we don't have a database or anything to enter a VIN). I was able to find it had a 12 inch wheel though, so really all you need to know is your wheel bolt pattern, and then you can choose which wheel you want. It'll be either 4 on 4" or 5 on 4-1/2" and I've added links below to a help article on measuring your wheel bolt pattern...

  • Torque Specification for 12 Inch Wheel with 4 Lug Nuts on Boat Trailer
    I have attached a chart for you to take a look at that includes the lug nut torque specifications. If your wheel uses 1/2 inch lug nuts or wheel bolts like the 12 Inch Steel Spoke Trailer Wheel # AM20124 referenced in your question, you will torque them to 75-85 foot pounds. If you have different size lug nuts, then you will just follow the specifications included in the chart for that size on a 12 inch wheel.

  • Looking For Wheels That Will Fit 5.30-12 Trailer Tires
    Hello Geralyn, thanks for reaching out. We do offer wheels that will fit the 5.30-12 trailer tires. I will just need to know what bolt pattern you need because we have both 4-lug and 5-lug options. Here is what I recommend: - Steel Spoke Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - Galvanized Finish # AM20134 - Steel Spoke Trailer Wheel - 12" x 4" Rim - 4 on 4 - Galvanized Finish # AM20124 The link below will show you our full selection of 12" wheels.

  • Availability of Galvanized Wheel and Tire 5.30-12 with Higher Speed Rating
    Hey Scott, the only way to accomplish what you are looking for is to order the wheel and tire separately. For that you'd want the part # TT53012C for a tire that matches the size you need and has the higher speed rating of 81 mph plus the wheel part # AM20124. Now I wish we had the ability to mount tires here but that's not an option we have at this time so you would need to find a shop local to you and have them mount the tires.

  • Upgrading Trailer Tires and Wheels For Highway use on Harbor Freight 4x8 Folding Trailer
    From my research on the Harbor Freight 4x8 folding trailer uses 4.80-12 tires on a 12 inch wheel for the 1195 lb capacity trailer and a 5.30-12 for the 1720 lbs capacity trailer. It is a good idea to check your existing tires to see which size they are. I recommend Taskmaster 5.30R12 part # TT53012C If your existing tires on the trailer are 5.30-12. If your existing tires are 4.80-12 I recommend Taskmaster part # TT48012C. Both of these tires are radial tires which are designed to...

  • Correct Lug Nut Torque for 12-Inch Steel Trailer Wheel
    For a 4-lug steel wheel with 1/2-inch studs like # AM20124 the correct torque range is 75-85 ft-lbs. For a 15-inch steel wheel like the item # TA37RR that you referenced the torque range is 90-120 ft-lbs. In general the larger a wheel is the more torque it requires and steel wheels typically need higher torque than aluminum wheels.

  • 4 Lug Trailer Wheel and Tire with Higher Speed Rating
    You'd need to go with the tire part # TT48012C as it's only option for 12 inch wheel that has an 81 mph speed rating and then for a matching wheel part # AM20124 which has the 4 bolt pattern you need. We also don't have a way to mount them here.

  • Replacement Tire for Highway Use on 4x8 Ultra Tow Foldable Aluminum Trailer
    The best option for a highway tire is going to be switching to a radial. Radial tires have better performance in general, especially on the road. The Taskmaster 4.80R12 Radial Trailer Tire # TT48012C would be the best choice. This tire has a capacity of 990 lbs at 90 psi and a max speed rating of M for 81 mph. It will also fit on your existing wheels. We do not have a wheel and tire combination with a 4 on 4 bolt pattern so if you want wheels as well we carry 12" wheels like the # DEX44FR...

  • Replacement Wheel and Tire For a 1973 Dilly Boat Trailer With 4.80-12 Tires
    For a trailer with a 4.80-12 tire size you would need either a 4-Lug # AM20124 or 5-Lug # AM20134 wheel. We do have these with tires already installed as the 4-Lug Package # AM30630 or 5-Lug Package # AM30670 so you can just bolt them on and go.

    The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel - 4 on 4 - Load Range C # AM30630 is a good choice for you. Its galvanized wheel will resist corrosion and rust and is perfect for a boat application. This pre-mounted tire and wheel combination comes mounted and ready to install and is rated for highway speeds up to 65 mph. However, you mentioned you wanted higher speeds. If you want a speed rating of 81 mph, you would need to purchase the tire and wheel separately then...

  • Recommended Replacement for ST145/R12 Trailer Tires
    Trailer tires are designed to fit on certain wheels so if you have ST145/R12 trailer tires now, you do need to replace your tires with the same size or they won't fit. I recommend the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range D # AM10130 (1,220 lb capacity) or Load Range E # AM10140 (1,520 lb capacity) which will fit the Steel Spoke Trailer Wheel - 12" x 4" Rim - 4 on 4 - Galvanized Finish # AM20124. I have added links to video reviews for you to check out as well.

    Based on the numbers you listed what you have is a trailer tire size 5.30-12 Load Range C on a 12 inch trailer wheel with a 4 on 4 inch bolt pattern. For a combo that covers all of that aside from being a radial we have the # AM30780 for a white wheel or part # AM30790 for a galvanized wheel. None of the combos we offer in this setup have a radial option For just the tire we have the part # TT53012C which will work well and is a radial. Then for a wheel to match this we have the part #...

  • Are Trailer Wheel Hub Bore (Pilot Diameter) Measurements Universal Sizes
    The center hub bore size can vary between wheels so you will need to verify the hub bore size (pilot diameter) before replacing your 8" wheels with 12" wheels. For example, the Steel Spoke Trailer Wheel # AM20124 with the galvanized finish has the 4 on 4" bolt pattern that it looks like you have and a pilot diameter of 2.84". It looks like your current lug nuts sit flush against your wheel and they don't have a cone shape. If this is the case then you will need 60 degree coned lug nuts...

  • Valve Stem Mount Hole Diameter for the Steel Spoke Trailer Wheel # AM20124
    I went out to the warehouse and found that the hole for the valve stem on the Steel Spoke Trailer Wheel # AM20124 measured about 0.45" in diameter. We actually have the Americana Metal, Bolt-In Valve Stem # AM20906 which will fit perfectly with this wheel an can handle psi ratings over 100 so you never have to worry about the psi rating of your valve stem.

  • What Should I Torque My Lug Nuts To
    In order to determine what to torque the lug nuts on your 14" trailer wheels, you will need to know what size the lug studs on your hubs are. I've attached a helpful chart that will give you the torque specs for a variety of different wheels but you will need to use a dial or digital calipers to measure the diameter of the stud and then torque accordingly.

  • Speed Rating of Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel
    The speed rating of the Kenda 5.30-12 Bias Trailer Tire with 12" Galvanized Wheel part # AM30790 is 65 mph. That's pretty much the max for a bias ply tire this size but if you switch to a radial like the Taskmaster 5.30R12 Radial Trailer Tire part # TT53012C you can get up to 81 mph. You will have to add the wheel separate though, it's the Steel Spoke Trailer Wheel part # AM20124.

  • What Is The Widest Trailer Wheel That Use The 4 on 4" Bolt Pattern?
    The widest wheel with the 4 on 4" bolt pattern is going to come down to which size wheel you are needing. For example if you are needing a 12" wheel the widest wheel is 4" like the Steel Spoke Trailer Wheel - 12" x 4" Rim - 4 on 4 - Galvanized Finish # AM20124. If you need a 13" wheel the widest wheel is the # AM22322HWTB which is 5" wide, and if you need a 10" wheel the widest wheel is the # AM20041 which is 6" wide. If you are looking for a different size wheel just let me know. I...

  • Solution for Getting Taskmaster Trailer Tire # TT53012C Mounted on 4 Lug Wheel
    Since we don't have the # TT53012C mounted on a wheel with a 4 on 4 inch bolt pattern you'd need to also get a 4 lug wheel so you could have it mounted locally like with the part # AM20124 for a galvanized wheel or part # AM20140 for a white wheel.

  • Best Trailer Wheel and Tire in Size 4.80-12
    We don't have it pre-mounted to a rim but the best tire for your size is the Taskmaster 4.80-12 part # TT48012C as it has a higher speed rating at 81 mph compared to other options which are only rated for 65. Exceeding the speed rating of a tire is known to cause failure since it causes heat build up. Our most popular wheel then would be the part # AM20124 which has the bolt pattern you need of 4 on 4 inch.

  • Are the Steel Spoke Trailer Wheel - 12" x 4" Rim Hub Centric or Lug Centeric
    The Steel Spoke Trailer Wheel - 12" x 4" Rim - 4 on 4 - Galvanized Finish # AM20124 are lug centric. If you have a hub centric setup then you will not be able to use these wheels and need to match your current pilot diameter. If you have a lug centric setup then the larger pilot diameter of 2.84" will work. The pilot diameter only has to match if you need hub centric wheels, otherwise as long as it is the same size or larger it will work.

    The Steel Spoke Trailer Wheel - 12" x 4" Rim - 4 on 4 - Galvanized Finish item # AM20124 weighs 9 lbs. For a great tire I recommend the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire item # AM10130.

    You can get the Kenda Karrier S-Trail ST145/R12 (load range D) with the same galvanized wheel that has a 4 on 4" bolt pattern. The tire and wheel come separately so you'd have to get the mounted, but here are the part numbers: - Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range D # AM10130 - Steel Spoke Trailer Wheel - 12" x 4" Rim - 4 on 4 - Galvanized Finish # AM20124

  • 5.30-12 Load Range D Tire Mounted on Galvanized Wheel with 4 on 4 Bolt Pattern
    We don't offer a wheel tire combo with a load range D tire, but you could always purchase the # AM10068 and the # AM20124 wheel separately and have them mounted locally. Another option would be to go up to a 13 inch wheel/tire like # AM3S130. This tire is 1 inch wider and would move your tire about 1 inch closer to the underside of the fender/wheel well. As long as you had at least 3-4 inches of clearance when the trailer is loaded, that would work fine for you. The tire is a 175/80-13...
