This 9" x 4" steel wheel is made to handle everyday towing and cargo duty without flex or fatigue. With a capacity of 1,120 lbs and a 0 offset, it’s a solid option for trailers that see regular use. The solid-center design keeps things simple and strong, so you get dependable support with every mile.
Corrosion doesn’t stand a chance thanks to the protective finish. A white powder coat applied over an e-coat primer seals the steel against moisture, road grime, and salt. It keeps the wheel looking clean and performing well even after long stretches in damp or rough environments.
The wheel’s 4 on 4" bolt pattern, matched to a 2.5" pilot diameter and 1/2"-20 bolt size, takes the guesswork out of fitment. Everything lines up cleanly for a snug, balanced mount that stays true under load. Meeting DOT specifications means it’s built to standards that keep your setup safe and reliable.
When you’re matching tires, this wheel works with 9" tire sizes like the 6.90/6.00-9 Kenda Loadstar #AM10040. Together they form a setup that runs smooth, holds air well at highway pressures, and offers dependable grip under heavy loads—all key for confidence when you’re towing long distances or hauling gear week after week.
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"

They do use a white powder coat finish over an e-coat primer over the whole wheel and this wheel does meet the DOT, Department of Transportation specifications.Your dimensions on this, the diameter again is nine inches. And if we measure that, the diameter is always measured inside the inside. So if we take our tape measure and we go inside the inside, there's your nine inch diameter. Width on it is the same way, inside to inside or bead seat to bead seat.
There's your four inch width.The bolt pattern on this wheel is a four on four inch bolt pattern and if you wanted to measure that on a wheel, that's an even number of lugs, in this case, four, all you do is pick one of the holes, measure from the center of that hole directly across to the center of the hole right across from it. So there's your four inch bolt pattern, four on four inch bolt pattern.This wheel does usually need 00:01:00 a lug size of a half inch by 20. Weight capacity on this wheel is 1120 pounds and the last measurement is the pilot hole diameter, the large hole here in the center of the wheel, goes over the hub on your trailer.
