When you’re towing anything that needs dependable support, this steel wheel is rated for 1,250 lbs and meets Department of Transportation standards. The 12" x 4" rim with a 4 on 4" bolt pattern handles weight confidently without flexing or wobbling under load. Its zero offset design keeps balance consistent and helps the trailer track straight mile after mile.
Moisture, road salt, and grime can eat through an unprotected wheel fast. This one’s built to resist it all with a white powder coat finish layered over an e-coat primer. The combination locks out rust and keeps the surface smooth and clean longer, even if it spends plenty of time around water or humidity.
No guesswork on fitment here. The wheel uses a standard 4 on 4" bolt pattern, a 2.84" pilot diameter, and accepts 1/2"-20 lug nuts. These are common specs that make it easy to match up with the right hub and hardware, so you can install it and get rolling without fuss.
This isn’t light-duty material—it’s tough steel built to take regular use and still look good doing it. The classic 8-spoke design adds strength while keeping weight reasonable, giving you confidence that the wheel will stay true whether you’re running empty or fully loaded.


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.
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).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Today we're going to review part number AM20122. This is the Americana 12 inch by four inch Steel White Spoke Trailer Wheel with a four on four bolt pattern and a white powder coat finish. This wheel is built with a sturdy steel construction, has a white powder coat finish over a e-coat primer for excellent corrosion resistance. You can see it is the eight spoke pattern, and this high quality wheel does meet the Department of Transportation specifications. Now, a few measurements on this. The rim dimension is a 12 inch diameter by four inch wide, and basically on a wheel, when you measure it, the diameter, you would not measure edge to edge. It's actually where the tire bead seat to bead seat.
Basically, when a tire's mounted on this wheel, the bead seats of the tire would sit right in here, so basically, when you measure the diameter, it's the inside measurement of that tire. The bead seat to bead seat would be the diameter on this wheel, so if we put it across, you can see 12 inch diameter. The width would be the same way. It wouldn't be edge to edge. It's going to be bead seat to bead seat, which is the inside. Again, you can see four inches wide.
Now, the bolt pattern on this, you can see is four lugs and a four inch bolt pattern. Basically, the way to measure a bolt pattern, when it's an even amount of lugs, like in this case four, you just pick one of the holes, measure from the center of that hole directly across to the center of the hole directly opposite from it. In this case, if we go center to center, you can see four inch is the measurement, so four on four inch bolt pattern. This does use a wheel lug or bolt size of a half inch by 20. Now, the pilot hole diameter, which is this large hole here in the center, this goes over the hub on your trailer. It would measure 2.84 inches.
If we put a ruler on there, you can see about 2.84 inches. Then, the weight capacity on this wheel is 1250 pounds. That should do it for the review on part number AM20122, the Americana 12 inch by four inch Steel White Spoke Trailer Wheel, the four on four bolt pattern in a white powder coat finish. .
