Taskmaster Tires and Wheels - 550550SM1

This 15" x 5" steel trailer wheel has a 5 on 5 bolt pattern and a 3.19" pilot diameter. Improved torque retention keeps wheel secure when mounted on your axle. Rust-resistant, 3-step powder coat finish. Valve stem is included.

  • Capacity: 1,870 lbs
  • Pilot diameter: 3.19"
  • 2-Year limited warranty


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.


Improved Torque Retention Technology

Beveled Stud Holes Front and Back

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 - 550550SM1 Review

Today we're going to take a look at the TaskMaster 15 inch by 5 inch silver modular steel trailer wheel with the 5 on 5 inch bolt pattern. Now this steel wheel has the modular design and when we say modular design, that's the one that has the round holes all the way around the wheel. It's very sturdy and corrosion resistant. This wheel does use a 3 step finishing process that would first include a zinc phosphate bath, then an e-coat primer, and then the silver powder coat on the front of the wheel and on the back of the wheel what they do is lightly e-coat it to reduce friction and provide rust resistance with less flaking. Now, this wheel does use the ITR technology which is improved torque retention. This is designed to help keep the wheel securely in place on your trailer. They have the uncoated stud holes that are beveled to give you better clamp force retention.

Now the valve stem is included when you receive the wheel the valve stem does come with it. This wheel does meet the SAE standards. Few specs on this, the diameter of the wheel which is measured inside the inside is 15 inches so take a tape measure and I want to show you if you measure the . you can see right at 15 inches for the diameter. The width is the same way, you measure inside the inside where the tire beads would seat.

On this one it's 5 inches, so 15 inch by 5 inch. Now, the bolt pattern on this wheel is a 5 on 5 inch bolt pattern. If you ever want to measure a bolt pattern on a wheel that's an odd number of lugs like in this case 5 what you want to do is pick any one of the holes, let's say this one. Then you'll measure from the center of that hole directly across to either one of these holes, just pick one. You'll measure to the furthest edge. Center of the starting hole to the furthest edge, let's see if we put the tape measure on this wheel center, start to furthest edge is 5 inches.

5 on 5 inch bolt pattern. This wheel does use the wheel lug size of a 1/2 inch by 20. Now, the weight capacity on this wheel is 1,870 pounds. The pilot hole diameter which is this large hole here in the center of the wheel, goes over the hub on your trailer, the diameter of that opening, put the ruler on it and you can see it's going to be right at 3.19 inches for the pilot hole diameter. That should do it for the review on the TaskMaster 15 inch by 5 inch silver modular steel trailer wheel with the 5 on 5 inch bolt pattern.

I ordered these to replace the 14" wheels on my Carson flat bed trailer. I needed a second spare but 14" 5 on 5 wheels are almost impossible to find so I decided to convert the trailer to four 15" tires and two 15" spares. The wheels look great and are priced right. The FAST free shipping is awesome as well. Great job E-Trailer! 347840

The trailer rims were priced right and exactly what I was looking for, see the attached photo. Problem solved with the zero offset wheels, since the rims on my used trailer were old Chevy wheels and were blowing my tires out by rubbing the inside wheelwell. Thanks! 254217

These wheels were the best bang for the buck I could find on the internet and I had them in 3 days a week before Christmas!! I'm very pleased with the purchase and the wheels appear to be quality built. From past experience with wheels of this type I've sealed the joint between the hub and rib with caulking hoping to prevent future rusting which originates in this area. 234390

Good looking wheels with the added load rating I needed on my 18' tandem car hauler. Had them balanced with no problems. These replaced some out of round galvanized wheels, and I am very happy with these wheels and the Etrailer customer service and quick shipping. I would have given 5 stars, but am concerned the backside paint is not as substantial. However they were described as such in the product data. 545642

Review from a similar Taskmaster Silver Steel Modular in Tires and Wheels


I recently wanted to upgrade my trailer towing reliability and wanted to go to a heaver load rated tire. My existing wheels were to narrow for the 225 tires and my wheels looked shabby. I not only upgraded to a way better tire combination but I also got these great wheels to go with them! Rated at 2830 lbs to match the new larger tires and look fantastic so a great wheel and at a great price! I couldn't get the old wheels cleaned and repainted for twice the price of new wheels and these look great! Did I mention fast free shipping and in two days I was DONE & ready to go racing! Thanks etrailer.com! 475665

Review from a similar Taskmaster Silver Steel Modular in Tires and Wheels


I needed another rim for a spare tire. This is the best place I could find to buy one. The price is very competitive. I arrived quickly. It is identical to the ones already on my trailer, right down to the same stickers and even where the stickers are placed... like they came off the same assembly line. It is a heavy steel rim that should last many years. I don't need to post a picture because the one the company posted could be of my rim. 377283


Comments

My trailer has two axles, so I bought this rim in order to have two spares. Ive driven thousands of miles with this trailer and the rim mentioned has been on the ground with one of the newer tires for many of those miles. It was a good buy. No regrets at all.

I bought these to replace the 5" white, spoked rims on my new car trailer. Can't beat the price and were at my door in two days. They are 1" wider and a much better wheel than the stock ones. I'd rather have aluminum but these look real good for a lot less than aluminum. 338405

Still looking good and working fine.

The Ultra-Fab reciever was just what I needed to mount our bike rack to the motorhome and still be able to pull the motorcycle trailer.Installation took less then 10 minutes. The Taskmaster steel modular trailer wheel is being used as a mock-up for several of us that have enclosed race car trailers that want to use a load range "E" comercial tires in the 225-75-16 size.If the fit and clearance is good more wheels will be ordered. 214033
