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.


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 - TTW240545SM1 Review

Today we're going to take a look at the Taskmaster 12" by 4" silver, steel, modular trailer wheel, with the 5 on 4-1/2" bolt pattern. This wheel's a steel wheel. It has the modular design. When they 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 uses a 3-step finishing process which will first include a zinc phosphate bath, then an eco primer, then they do a silver powder-coat on the front of the wheel.

If you notice on the back of the wheel it's slightly e-coated to reduce friction, provide rust resistance with less wiping. This wheel does use the ITR technology which is improved torque retention. It is designed to help keep the wheel securely in place on your trailer. It does use the uncoated stud holes right here which are beveled to give you better clamp force retention. If you also notice, they come installed with a metal, high pressure valve stem. This wheel does meet the SAE standards. A few specs on this, we'll measure the wheel.

The diameter is 12" and that's always measured inside to inside. If we take our ruler, inside to inside you can see is 12" in diameter. The width is the same way. Bead seat to bead seat, so an inside measurement is right at 4", so 12" by 4". The bolt pattern on this wheel is a 5 on 4-1/2 inch bolt pattern. If you want to measure a bolt pattern on a wheel like that's an odd number of lugs, just pick any hole, let's say this one, and then you'll measure form that hole directly across to either one of these.

The key is, you want to measure from the center of the starting hole to the furthest edge of the hole that you measure to. If we take our tape measure again, center to furthest edge is 4-1/2", so, 5 on 4-1/2" bolt pattern. Let's use the wheel lug size of a 1/2" by 20. Weight capacity on this wheel is 1,250 pounds. The pilot hole diameter, which is the large hole here in the center of the wheel, goes over the hub on your trailer, the diameter of that opening is going to be right 2.95". That should do it for the review of the Taskmaster 12" by 4" silver, steel, modular trailer wheel with the 5 on 4-1/2" bolt pattern..

Ordered a spare wheel for my boat trailer, which was supposed to ship within 48 hours, got an email from George at etrailer later that same day, stating that he got my package out the "same day"! That's what I call.....service! Package arrived quickly and product was in excellent condition. Have ordered from etrailer in the past, and any time I need a product that they carry, I would not hesitate to order from them again! Very satisfied with both product and service! Five start for sure! 669780

What can you say about a wheel? It's round and looks good. I have no doubt once fitted with a tire it will be fine. That said, I'm pleased with etrailer. Over the years I've bought a number of products from etailer and they have always been good products. Sometimes a little pricey but definitely good products. 628420

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


Upgraded to a better tire for our teardrop camper. Best decision ever. The previous 12 inch tires were always having issues (from a tractor place). These tires perform well, and have not had any problems (no separation, goose egg's, improper wearing, etc). When these get worn, I will be replacing with the same from etrailer. (Axle, wheels, and tires were all purchased from etrailer.com) 690578

Not only is the product a very good value, but it was delivered very quickly, faster than the time frame that it was originally scheduled... I have dealt with etrailer before and as usual the service is always excellent and products are always described to the fullest.. Your videos are excellent in showing not only the product, but in many cases it also shows how to install or properly get ready for installation... The company is 5 STARS and Beyond.... Will always recommend etrailer and will continue to buy from them in the future... 462083

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

Very satisfied so far, I have only mounted and balanced them but they seem to be nice and true, nice quality of wheel from what I can see. Etrailer had very quick shipping, and good communication throughout order process. 202717


Comments
I put these wheels on a 30 foot fifth wheel and over the passed year have put several trips on them still very happy with how they are handling the elements, road debris, and just Midwestern road or lack of. Im still very happy with them and would and have recommended them.

The heavy duty steel rims are exactly what I wanted. I went from a load range E to a load range G set of trailer tires for my camper and my aluminum rims were not rated for the heavy tires. 540148

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.

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

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


After placing my order these arrived sooner than the projected date. I had upgraded to a sturdier axle on my trailer and needed more substantial wheels (with a different bolt pattern). Compared to other retailers these were relatively inexpensive, which is exactly what I wanted for my trailer. What else can I say? The wheels on the trailer go round and round.... 357423

  • Recommended Replacement for ST145/R12 Trailer Tires
    Trailer tires are designed to fit on certain wheels so if you have ST145/R12 trailer tires now, you do need to replace your tires with the same size or they won't fit. I recommend the Kenda Karrier S-Trail ST145/R12 Radial Trailer Tire - Load Range D # AM10130 (1,220 lb capacity) or Load Range E # AM10140 (1,520 lb capacity) which will fit 12" x 4" wheels like Taskmaster Steel Modular Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - Silver # TTW240545SM1 or Steel Spoke Trailer Wheel - 12"...

  • Best Trailer Wheel That Will Fit A 4.80-12 Tire
    It sounds you are looking for a new trailer wheel for your 4.80-12 trailer tires. Your 13 inch is like just a 12 inch wheel, but you may be measuring the overall diameter. Trailer wheel diameter is actually measured from bead seat to bead seat rather than overall, so a 12 inch diameter wheel may look more like a 13 inch diameter wheel. I'm guessing your wheel bolt pattern is actually 5 on 4-1/2 because 5 on 4.25 is not a common trailer wheel bolt pattern. I've attached a help article on...
