Corrosion-Resistant Finish

The 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

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.


Bias Tires vs. Radial Tires

Bias vs. radial tire graphic

Bias ply tires are designed for off-road or agricultural applications. They are built with thick, durable nylon cords that are positioned at a 30- to 45-degree angle to the direction of travel. The layers alternate in a crisscross pattern, making the sidewalls stiffer so that the entire tire is able to flex easily. As a result, the tire provides a smooth ride and improved handling when trailering on uneven surfaces.


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 - Tire with Wheel - TTWA225B6SM Review

Today we are going to review part number TTWA225B6SM. This is the taskmaster ST22575D15 Bias trailer tire in a load range D. It's mounted on a 15-inch silver modular design wheel. It has a six on five and half inch bolt pattern. Now, this tire wheel assemble is ideal for boat trailers, stock trailers, utility trailers, and campers. It does come all assembled.

Basically the tire will be mounted on the wheel and filled with air. The wheel is a steel modular design, which is sturdy and corrosion resistant. Now, when I say modular design it's actually the description from observers when it has the round holes that go around the whole edge of the wheel here. Now, the wheel uses a three step finishing process, and that includes a phosphate zinc bath, then an e-coat primer, and then the silver powder coat finish over that. The inboard side, or the back of the wheel, is lightly e-coated to reduce friction and provide rust resistance with less flaking. Now, this wheel does use the ITR technology, which is the improved torque retention.

This helps to keep the wheel securely in place on your trailer. Basically, the way they do that is if you've noticed around the lug holes it is actually raised some. Then the lug hole itself is beveled and then coated and then that'll allow you, when you go ahead and put this on your trailer and you tighten your lug nut down, it will help maintain that torque that you put on the lug nut thats holding it onto the trailer. The tire on this is a bias ply tire, which is constructed with strong nylon cords. It does have the tread wear indicators or tread depth indicators, which will offer a quick visual indicator of your tread wear. It's the same that's used on passenger car tires, if you've noticed on the sidewall there will be a triangle here and if you go about 12 inches there will be another triangle, so about every 12 inches there is a triangle.

What that's pointing to is if you go look at the tread in the grooves of the tread you'll see a raised rubber area and almost looks like a speed bumper in there. Basically what thats doing is that raised area is at 230 seconds tread depth. When this tire would wear down to 230 seconds that tread wear indicator would be straight across, which means to tell you that the tire is worn out. That gives you a nice visual indicator of the tread wear on the tire. This tire and wheel assembly will meet the Department of Transportation specifications and it does exceed the federal motor vehicle safety standards. A few specs on this wheel.

The dimension is 15 inches, the width of it is 6 inches, the outside of the bolt pattern of six on five and a half inches, does use a wheel lug size of a half inch by 20 and the wheel capacity on just the wheel is wheel is 2600lbs. Now the pilot hold diameter, which is this large hole in the center of the wheel, this goes over the hub on your trailer, the diameter on that is 4.25 inches. Now, the tire size it is stamped on the tire, you can see right here ST for special trailer 22575D15, and the D in there designates that it's a bias tire. Now the section width on this tire is 8.3 inches, the overall diameter, which would go from the very bottom to the very top when it's inflated, is 28.3 inches. This is a load range D tire, which means it has a 8-ply rating and the maximum load on just the tire is 2530lbs. at 65 psi. That should do it for the review on part number TTWA225B6SM, and thats the taskmaster ST22575D15 bias trailer tire mounted on the 15-inch silver modular design wheel. .

This is an early review I do not have any miles on them yet. I purchased a set of 4 of these. Do not just throw them on your trailer. Make sure you check the pressure (mine ranged from 35 to 55PSI) and fill to 65PSI for full load rating. Check the balance. Normally I don't care about the balance on trailer tires but on my RV trailer I like to know they are close. Not one of these tires were close to balanced. 1+oz. out was the norm and one was 3/2oz in/out - that one we dismounted and spun the tire on the rim, it was closer after that. 1+oz out of balance will cause ride/wear issues so I am glad I checked that. Pet Peeve: 2 stickers stuck to the face of the rims that do not peel off. They come off in pieces and leave behind the adhesive. No big deal but if you want clean rims budget in some time for cleaning off the stickers. 214688

I don't typically order stuff online mainly cuz I'm pretty old school, so I called Etrailer and asked if I could confirm what tire I needed and if I could order it thru her and she (Tori) said she would be happy to help and she was spot on great at her job. Not to mention she told me I would recieve it in roughly a week, but it was ordered on Monday before the 4th and ups dropped it off on wed. 2 days later! 209502
