  • Wheel Only
  • 12 Inch
  • 5 on 4-1/2 Inch
  • Steel Wheels - Powder Coat
  • Taskmaster

This 12" x 4" steel trailer wheel has a 5 on 4-1/2 bolt pattern. 3-Step powder coat finish provides rust resistance and improved torque retention keeps wheel secure when mounted on your axle. Valve stem is included.


Features:

  • Steel wheel with modular design is sturdy and corrosion resistant
  • 3-Step finishing process includes zinc phosphate bath, e-coat primer, and silver powder coat on outboard side
    • Inboard side is lightly e-coated to reduce friction and provide rust resistance with less flaking
  • Improved torque retention (ITR) technology helps to keep wheel securely in place on your trailer
    • Uncoated stud holes are beveled to offer better clamp force retention
  • Valve stem is included
  • Meets SAE J1204 standards


Specs:

  • Rim dimensions: 12" diameter x 4" wide
  • Bolt pattern: 5 on 4-1/2"
  • Wheel bolt size: 1/2"-20
  • Capacity: 1,250 lbs
  • Offset: 0
  • Pilot diameter: 2.95"
  • 2-Year limited warranty


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.


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"

Overall good looking wheel. Price was good for what I was looking for. Box was dinged up a bit although I expected that to happen, something that heavy is bound to beat up the box. Paint was very nice. Having the tire installed today and we will see how nice it looks when I pick it up.



by:

They've worked great fit perfectly put them on a stock trailer



by:

I wanted black wheels instead of the white ones that came on the trailer. I liked the extra rust prevention provided in the description. I have just received them so they are not installed yet but the finish and style look amazing, the online pictures don't do them justice.



by:

Just got the new tire mounted on the rim! Now I'm looking for lug nuts and bolts for a heavy duty tilt trailer 8 hole lug. I'm also looking for a brushed aluminum 16" rim with the identical pattern as the one I just purchased. The steel rim will then become my spare.

Thank you



by:

Love the rims and tire. I have 4 more that I use on my food truck and they are great.



by:

Wheel size was right and shipping was great. I put a spare on it for my RV.



by:

I'm rating this trailer wheel as Excellent for a few reasons. First, the cost of the wheel is low for the quality of the product. Second, the wheel has kept its color and shine for over a year of substantial use. Third, the durability is awesome! We travel too many areas with tough terrain and the wheels need to be strong enough to handle the hits that come with the areas we access. These wheels do just that and do it well.



by:

The only lights that will fit on our trailer. Glad you have them in stock!



by:

Great quality wheel. Also the taskmaster inner packaging and the ETrailer outer packaging was superb. Thank you for packaging it so well for transit.

This has been an unfortunate on-line learning experience for me. I thought I had finally found a set of rims that fit my 1972 Ford F250. I entered my vehicle and read the line that stated...
Heavy-duty steel wheel with modular design is sturdy and corrosion resistant
Designed for use on trucks, buses, and trailers
Even though "use on trucks" is stated, these wheels are only approved for trailers. When I sought to return the wheels, I was surprised to learn that I would be out $[XX] for shipping on a $[XX] purchase. So even though etrailer is willing to refund the cost of the wheels, I will be out a couple of hundred dollars, with nothing to show.
Buyer beware! No more on-line orders for me. The risk is the worth the cost. That is what I have learned from this transaction.



by:

very disappointed to find the inside 4.25 center hole was misshapen when the stud holes were punched .it scratched my brand new flat black caps .will have to grind at each hole to round them and repaint everything. not very good for premium steel wheels. this is the second set of 5 I have bought . the first set was fine because the caps were loose.



by:

Matches my other rims, looks great!



by:

Looks like great quality, and arrived very well packaged and just what I was needing.



by:

The Vesper wheel rims are very good rims. The paint is good as well



by:

Wheels are fine but ups wasn’t gentle with the boxes.



by:

No issues at all. I use my trailer at least 2x monthly for hauling Off-road jeeps to and from the trails 20K+ lbs.



by:

Exactly what I needed for a spare wheel. Etrailier was helpful in making sure I ordered the correct produce. I’m having tire installed today. SHIPPING WAS FAST ordered on Friday and received Tue. ( a day earlier than original date - thanks UPS.

I HIGHLY RECOMMEND USING ETRAILIER



by:

The wheel in itself is a great wheel for the price. however unbeknownst to me once these arrived i took them straight to the tire shop (in the box) with the new G rated 14ply trailer tires to have them mounted. tire shop advised that once they opened the boxes, several wheels were bent around the rim. although it looked ugly luckily, the tires mounted okay. i had to buy some chrome rings to cover the ugly bends and dents (so more money) and contacted etrailer only to be told "oh sorry to hear about that. what i should have done was sent them back but they were already mounted and i would be charged again for that. didnt get any credit or discount offer from etrailer, they just seemed to not care. i've always purchased my trailer parts from etrailer because they've always been good to me, but i guess good thing must come to an end.



by:

All 4 wheels arrived on time and undamaged. I just had the new tires mounted and the combo looks great. I'm excited to get them on our camper to see how the whole package looks. When the mechanic mounted the tires he balanced everything right away and said that one wheel was off by quite a bit. So, depending on what you are putting these on, consider getting them balanced right away.



by:

Wheels are well made. Great price also. Shipping is fast. Im satisfied



by:

Great deal for a 6 on 5.5 rim.
Perfect

Delivered two days early thanks to George J for upgrading my shipping free of charge
Thank you etrailer



by:

Great Service! Showed up on time just like they said! Would recommend this company highly!



by:

You had them in stock and fill the order in a timely manner. Received the rims in excellent condition. Thank you for your service in providing all the great products for us trailer haulers.



by:

Smoking fast shipping and it is exactly what I order, can’t ask for better than that !!!

  • Recommended Replacement Tires and Wheels for 2007 Palomino Pony 2100
    I was able to do a little research and determine your 2007 Palomino Pony 2100 does have the 5 on 4-1/2 inch bolt pattern. I've linked the page to all the 5.30-12 combinations we offer with that bolt pattern to assist. My recommendation is the Taskmaster 5.30R12 Radial Trailer Tire - Load Range C # TT53012C and the Taskmaster Steel Modular Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - Silver # TA79RR. We do not have these tires mounted on a wheel, but this will be your best scenario. These...

  • Recommended Spare Wheel/Tire for 2006 Load Rite Snowmobile Trailer with 5.30-12 Tires
    The Taskmaster 5.30-12 Bias Trailer Tire with 12" White Mod Wheel part # TA86RR would be a great spare if you have bias ply tires. If you have radial tires, you would need to purchase the tire and the wheel separately and have them mounted at a local shop. For the tire, Taskmaster 5.30R12 Radial Trailer Tire - Load Range C Item # TT53012C. Then for the wheel, you could go with the Taskmaster Steel Modular Trailer Wheel - 12" x 4" Rim - 5 on 4-1/2 - Silver # TA79RR. In order to store...

  • Can Tire Load Ratings Be Different From One Trailer Wheel to the Other?
    We do offer the Taskmaster Steel Modular Trailer Wheel # TA79RR separate from the Wheel and Tire # TA96RR. This will allow you to mount the Load Range B # AM10060 tire on the Wheel # TA79RR. It is best to not mix and match tires when it comes to size and load rating as this could have adverse effects on the trailer ride quality and tracking behind your tow vehicle.

  • Recommended 5.30-12 Wheel/Tire with 5 on 4-1/2 Bolt Pattern for Trailer
    I have some great 5.30-12 wheel/tire options with 5 on 4-1/2" bolt pattern for you to choose from. I like the Taskmaster 5.30-12 Bias Trailer Tire with 12" Silver Mod Wheel - 5 on 4-1/2 - Load Range C # TA26RR. However, I recommend going with a radial ply option as these will run cooler on the highway therefore last longer. This would require you to purchase the tire and wheel separately and then have them mounted at a local shop upon arrival. For the tire, I recommend the Taskmaster...

  • 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...

  • 12x4 Inch Trailer Wheels with 5 on 4-1/2 Inch Bolt Pattern
    We do have many 12x4 inch wheels with the 5 on 4-1/2 inch bolt pattern. The center pilot hole you referenced is and interesting question because trailer wheels are not centered on the hub so the size of that hole isn't as important as the bolt pattern that helps center the wheel on the hub. We have no pilot holes that are 2.75 or 2.8 inches in diameter but we do have the -Taskmaster Steel Modular Trailer Wheel - Silver # TA79RR with pilot 2.95 inches I've linked the page to your other...

  • Will 5.30R12 Tires Be a Good Replacement for Original 5.30-12 Tires
    The # TT53012C 5.30R12 tires you'd looked at are just about a 1/4 inch narrower and about 1/3 of an inch smaller in diameter than your existing 5.30-12 tires. The # TT53012C would work perfectly fine for you, and if your existing tires are bias ply, the 5.30R12 will have a smoother, cooler ride. Excess heat builtup is the main cause of tire failure so keeping the tires as cool as possible is essential. The # TT53012C is a Load Range C tire with a 1050 lb per tire/2100 lb per axle rating....
