  • 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

  • Meets SAE J1204 standards

  • 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"

  • How to Switch to Radial Trailer Tires From 205/65-10 Bias Trailer Tires
    Hi Dan, You're right that radial trailer tires are a much, much better option for highway driving than bias tires because radials run cooler. This means they flex more for better traction and less chance of a blowout on long trips. And you can switch from 205/65-10 bias tires to radials, but you'll need a different size tire and new wheels because there aren't 205/65-10 radials. A 205/65-10 measures 20.5" in diameter and 8.1" wide, and a close option is a ST145/R12 tire which is 5.7"...

  • 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 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...

  • 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...

  • 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...

  • 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....

  • Looking For Spare Tire For Waverunner Trailer Dexstar 17-228 12x4 JA 1250LB
    Hello Stuart, thanks for getting in touch. We have a great option for you. According to the Dexstar catalogue, the 17-228 is a silver mod wheel with a 5 on 4-1/2" bolt pattern and no offset.

  • 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...
