Extreme Salt Resistance (ESR) Finish Is Environmentally Friendly

This wheel has an extreme salt resistance (ESR) matte black finish, which is sprayed on over a layer of e-coat primer. Compared to galvanized finishes, this highly corrosion-resistant finish withstands the effects of saltwater and inclement weather for a longer period of time. ESR-finished wheels performed for more than 700 hours in salt spray tests.


In addition, this ESR finish is an eco-friendly alternative to galvanized finishes, which can be bad for the environment.


Improved Torque Retention Technology

Dark Matter Beneved Lug Holes

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.


Bolt Pattern - Odd

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.)


Bolt Pattern - Even

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.)


Bolt Pattern - 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.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Video Transcript for Taskmaster Tires and Wheels - Wheel Only - 550545M1DMX Review

Speaker 1: Today we're gonna take a look at the 15 inch by five inch dark matter steel modular boat trailer wheel with the five on 4 1/2 inch bolt pattern and the matte black finish. This is a sturdy steel boat trailer wheel. It's a modular design. When we say modular design, that's the one that has the round holes all the way around the wheel. This one has a matte black finish on it, which is sprayed on over an E-coat primer. It's very corrosion resistant.

Does use an ESR finish. The ESR stands for extreme salt resistance. This'll help weather the elements better than your galvanized finishes, and when it's compared to galvanized finishes, this highly corrosion resistant finish will withstand the effects of salt water and inclement weather for a long period of time. In addition to ESR finish is an equally eco-friendly alternative to galvanized finish because the galvanized finish is extremely toxic to the environment. This is a tough, environmentally friendly coating.

It won't corrode on contact with the salt water. Has excellent corrosion resistance with a salt spray rating of more than 700 hours. Does use the ITR technology, which stands for improved torque retention. This is designed to help keep your wheel securely in place on your trailer. Basically what they do is they use uncoated stud holes here, which are beveled to give you better clamp force retention.

And if you notice on the wheel, the valve stem is included.Now we are gonna give you a few dimensions. Gonna give you the diameter. Diameter is always measured from inside to inside, or beat seat to beat seat. So if we take our tape measure and we put it on the inside-inside measurement, you'll see it's right at 15 inches for diameter. The width on the wheel, again, is beat seat to beat seat or inside to inside.

It's right at five inches, so 15 inch by five inch wide. Bolt pattern on this wheel is a five on 4 1/2 inch bolt pattern, and if you wanna measure that on a wheel, it's an odd number of lugs. The best way to do it is just pick any hole, let's say this one, and you're gonna measure across to either one of these holes, but when you measure it's from the center of the starting hole to the furthest edge of the hole that you measure to. So if we go center to furthest edge is 4 1/2 inches. So five on 4 1/2 inch bolt pattern. This wheel does use the wheel lug size of a half-inch by 20. Weight capacity on this wheel is 1870 pounds, and the last dimension we're gonna give you is this pilot hole diameter. This is the large hole on the wheel that goes over the hub on your trailer. Diameter of that opening is 3.19 inches.That should do it for the review on the 15 inch by five inch dark matter steel modular boat trailer wheel with the five on 4 1/2 inch bolt pattern and in the matte black finish.

Rims are ok, disappointed in the coating. It seems pretty soft. The matte black has already chipped away on the edges of the rim from rubbing in the box shipped. I suppose I will have to repaint these as they will rust. I was under the impression that this coating was more durable. I'm having a hard time believing that. 702693

Review from a similar Dark Matter ESR in Trailer Tires and Wheels


The Rims looked great and performed well. the shipping on them damaged the finish on them but after speaking with the Manufacturer, it turns out the ESR is a steel treatment and the finish is basically just a flat black powder coat so they were touched up before installation. etrailer is normally good about knowing their products but I had to find the manufacturer my self to get answers on how to touch these up after the poor shipping method damaged them because I didn't have time to get a return processed. seems all very inconvenient, Not a bad product, not bad service just ultra aggravating, will keep this in mind when shopping with etrailer in the future. 825182

First thought, I don't rate anything a 5 unless it's a winning power ball ticket. That said, the wheel I ordered was exactly what I needed to put a spare tire on my dump trailer. The wheel, and grease hub caps, ordered were well represented and explained on the website, were a good quality product at a good price and arrived a lot sooner than I expected. I am definitely a fan or etrailer.com. 732734

Ask the Experts about this Taskmaster Trailer Tires and Wheels

  • Correct Trailer Wheel Size for 235/75-15 Tire
    I do have a great option for you, however a 235/75-15 size tire will not fit the Dark Matter Steel Modular 15" x 5" Trailer Wheel # 550545M1DMX. This particular tire size needs at least a 6" width on the wheel for proper mounting. For a similar modular wheel in black that has the required 6 inch width I recommend the Taskmaster # 560545MBPVD instead. This sleek trailer wheel has a weight capacity of 2,830 pounds and the same 5 on 4-1/2" bolt pattern as the option you were looking at....

  • Will Taskmaster Dark Matter Trailer Wheel # 550545M1DMX Work on 3,500 Pound Axle
    The Taskmaster Dark Matter Trailer Wheel # 550545M1DMX features a weight capacity of 1,870 pounds, which would give you a combined load capacity of 3,740 pounds for the axle. This is plenty sufficient as you shouldn't be exceeding the 3,500 pound weight capacity on the axles for your trailer. We don't have matching Dark Matter lug nuts but the CE Smith # CE11051 is a good option and could be painted to match the wheel if desired. There again isn't a matching hub cover available...

  • Best 205/75-15 Tire for 7K Enclosed Motorcycle Trailer
    I really like the Goodyear Endurance ST205/75R15 Radial Trailer Tire # 724861519. It has a lead range of D (2,150 lbs at 65 psi), a max speed rating of 87 mph, plus it comes with a limited lifetime warranty with free tire replacement on workmanship defects. Obviously you'll need to remain under the load and speed ratings as well as practice good driving habits and keep it filled to the recommended psi rating for the best performance of the tire.

  • Availability of Taskmaster Provider ST205/75R15 LR D on Dark Matter Steel Modular Trailer Wheel
    You are correct that the Provider ST205/75R15 with the Load Range C # TTWTRTM2057515C is a 6 ply while the Load Range D # TR20515D is an 8 ply. The Load Range C is available on the Dark Matter Steel Modular Trailer Wheel with the 5 on 4-1/2" bolt pattern as part # A15R45DMM, but if you wanted to get the Load Range D with the wheel then you'd need to order them separately as parts # TR20515D and # 550545M1DMX and then have a tire shop mount them as we just get them shipped to use as...
