Corrosion-Resistant Finish
This steel wheel goes through a 3-step finishing process that makes it both attractive and corrosion resistant. The wheel is first submerged in a zinc phosphate bath to ensure good paint adhesion. It is then e-coated with an acrylic primer base and the outboard side is finished with baked-on DuPont powder paint. The light e-coat on the inboard side of the wheel reduces friction between the wheel and your hub and eliminates the flaking that can occur with a heavily applied paint finish.
The automotive-rated center disc is raised and the stud holes are beveled and uncoated for better clamp force retention. This technology helps the wheel stay tight against your hub without the need for constant retightening.
Determining the Bolt Pattern
The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.
To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)
On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)
Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a look at this Taskmaster 12 inch by four-inch silver steel modular trailer wheel with a four on four-inch bolt pattern. This steel wheel with modular design is sturdy and corrosion resistant. This wheel features a three-step finishing process that includes a zinc phosphate bath to ensure good paint adhesion, e-coated primer, and a silver powder coat on the outside. On the inside, it is lightly e-coated to reduce friction and provide rust resistance with less flaking.
Now, this features improved torque retention technology or ITR, which helps to keep the wheel securely in place on your trailer. Uncoated stud holes are beveled to offer better clamp force retention. As you can see, the valve stem is included. And this wheel meets SAE J1204 standards. The rim dimensions, from bead seat to bead seat is 12 inches in diameter.
And it is four inches wide, again, bead seat to bead seat. Now, the bolt pattern, as we mentioned, is four on four inches. And that first number in the bolt pattern is the number of bolt holes, which as you can see is four. And that second number denotes the diameter in inches of the circle on which the bolt holes sit. So, to determine the bolt circle diameter on wheels with an even number of bolt holes, you just simply measure from the center of one bolt hole and directly to the center of the hole across from it.
Now, the wheel stud size is a half-inch by 20 and the capacity is 1,250 pounds. The center cap is sold separately. Just make sure, if you do pick one up, that it fits the pilot diameter of 2.82 inches. And this has a zero offset. Well, that's gonna conclude our look today.
I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..
