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

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.

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 - TTWAS53012WM45HP Review

Today we're going to review Part Number TTWAS53012WM45HP and this is the Task Master 530 by 12 bias trailer tire in a load range C, modeled on this 12 inch white mod steel trailer wheel with the 5 on 4-1/2 inch bolt pattern. Now this tire wheel assembly is ideal for boat trailers, stock trailers, utility trailers and campers. The steel wheel is the modular design and by that it means it has the round holes all the way around the design of the wheel. It's very sturdy and corrosion resistant. Basically they use a three-step finishing process on this wheel. It's starts with a phosphate zinc bath and then an eco primer and then a white powder coat finish on the outside of the wheel.

In the inboard side they actually do a light e-coating to reduce friction and provide rust resistance with less flaking. This wheel does use the ITR technology, which is improved torque retention. This will help keep your wheel securely in place on your trailer. They use uncoated stud holes right here and they're beveled to offer better clamp force retention. The tire that's on this is a bias fly tire which is constructed with strong nylon cords. It is great for off-road and agricultural use and these tires do have a tread wear indicator every so often and they are marked on this shoulder TWI and basically what that means, tread wear indicator is right where the marking is.

If you go to the tread grooves, they're be a little raised bump almost like a speed bump in each groove that goes across the tire. That raised portion is at 230 seconds tread now and that's indicating a tire is worn out when it's at 230 seconds, so as this tire wears down you can look at that indicator in the tread grooves and it tells you how much tread wear you have left. It's a good visual indicator of your tread wear. If you also notice, they do use the high pressure valve stem, which is included. This assembly does meet the Department of Transportation specifications and it goes exceed your federal motor vehicle standards. A few specs on this assembly, we're going to start with the wheel.

The diameter on this wheel, which is measured, the diameter is always measured inside the inside, it's going to be 12 inches. The width is 4 inches wide. The bold pattern on this you can see is a 5 on 4-1/2 inch bolt pattern and the measure of bolt pattern on a wheel that has an odd number of lugs, in which case five, what you do is you just pick a hole, start with any hole and then you're going to measure to the hole, either one of these holes across from it, just pick one. What you're going to do is you'll measure from the center of the starting hole to the outer edge of the hold you're going to. On this wheel, it'll be 4-1/2 inches, so five lug, 4-1/2 inch bolt pattern.

This wheel does use a wheel lug size of a half inch by 20. Weight capacity on just the wheel is 1,250 pounds. Pilot whole diameter, which is the large hole here in the center wheel, it goes over the hub on the trailer, that diameter is 2.9 inches. Now the tire size, which is stamped on the size 530-12, it's a biased tire. Section width is 5.3 inches. Overall diameter from the bottom to the top when it's inflated is 21.5. This tire is a load range C. It means it's a 6-ply rated tire. The maximum load capacity on this is 1,050 pounds at 80 PSI and this tire does have a speed rating, a maximum speed of 81 miles per hour. That should do it for the review on Part Number TTWAS53012WM45HP. This is the Task Master 530 by 12 bias trailer tire in a load range C on this 12-inch white mod steel trailer wheel with the 5 on 4-1/2 inch bolt pattern.

I wish I had taken before and after photos of my trailer. A typical 5x8 utility trailer with the extruded wire mesh deck which I got for a bargain, perfect for my lawn tractor or 4 wheeler. However the 8" wheels did not provide enough ground clearance for the terrain where I intended to use it as a equipment hull trailer to our deer camp, pulled by the 4 wheeler. After finding etrailer.com my problems were solved! I ordered 5 bolt hubs, 5.30 x12" wheels and the economy plastic fenders and fender brackets. While waiting my order I wire wheeled the frame and gave it a fresh coat of paint and WHAL-LA! I have a new looking trailer! The order arrived in record time, securely packaged and great quality! I ordered the pre-packed hubs and didn't have to get into that sticky mess! Everything worked out as planned and was easy-peezy to assemble and install. I'll definitely use etrailer.com in the future. 720643

The outside paint finish on the rims is nice, though the inside paint is a bit sparse in spots, but the primer looks pretty good. The tires are tires, they look fine for small inexpensive tires, but the date codes on them reveal that one is 1.5 years old and the other 3 years old. For the price, I'm not going to fret it, I'll get 3-4 years out of these on my little 4x8 utility trailer, but in general I expect to get new tires that are less than a year old. 600546

Currently using on a jet ski trailer, so it sits often fully loaded. These tires flat spot so easily, do not get them. After only one year I have to replace them with radials because it shakes the trailer and the car. I drive 500+ miles with this trailer annually and I can't get the spots to come out. Go with radials 556471

Bias-ply tires work best for off road or agricultural use. For on-road use, radial tires do a much better job of shedding heat. Excess heat is the number one cause of tire failure and premature wear. Its also recommended that the tires combined load range exceeds the fully loaded weight of the trailer. Trailer tires should be kept fully inflated to the pressure listed on the tire sidewall.

  • Will Taskmaster Bias Trailer Tire Work As A Spare For Trailer With Taskmaster Wheel/Tire Combo
    All new production tires have the speed rating stamped on the tire now, but there may be tires around that are from an older production and do not have the speed rating stamped on them. The # TT53012C tire you are looking at would be a good spare for your trailer since you purchased the # TTWAS53012WM45HP wheel/tire combos since they are the same bias 6-ply tires of the same size.

  • Difference Between Taskmaster Wheel and Tires part numbers TTWAS53012WM45HP and TTWAS53012WS45HP
    The difference is the wheel design. The part # TTWAS53012WM45HP uses a mod wheel which has small round circles around the mounting flange and the part # TTWAS53012WS45HP has a spoke wheel that has holes that closely resemble a triangle. It's somewhat hard to see since the rims are so white and the background is white. But I attached a couple pictures for you to check out that show this. First one is a mod wheel and the second is the spoke.
