Platinum Plus Warranty with Roadside Assistance

This tire-and-wheel assembly comes with a Platinum Plus warranty that includes complimentary roadside assistance for 2 years. If your trailer has a flat tire, call the help line and a technician will come change out the flat tire with your existing inflated spare tire. The service is available 24 hours a day, 7 days a week. In addition to the roadside assistance, this warranty also includes other benefits and services.

Durable Acrylic Enamel Finish

Maxion Wheels Vesper Acrylic Enamel Finish

This wheel has a durable acrylic enamel finish on the front. The finish is applied after the wheel goes through an environmentally safe zinc phosphate pre-treatment and is coated with an e-coat primer layer. Compared to powder coat finishes, this finish resists getting chipped from flying road debris or scraped from hitting a curb for a longer period of time. These acrylic enamel wheels performed for more than 1,000 hours in salt spray tests.

Improved Torque Retention Technology

Maxion Wheels Vesper Improved Torque Retention

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.

Provider Radials with Automotive-Grade Tread

Provider Tread Vs Standard Tread

Unlike standard trailer tire tread, which has solid, continuous ribs, the automotive-grade tread on these Provider radials has ribs with breaks. These breaks allow water to run off to the sides. The Provider tread also has sipes. Siping is a process in which thin grooves (or sipes) are cut into the rubber of the tire. The grooves channel water away from the tread so that the tire makes better contact with the road. Both of these features greatly improve traction during wet, snowy, or icy conditions.

Provider radials are constructed with double polyester cords and double steel belts for increased durability and endurance. A protective layer of nylon is wrapped around the steel belts to help prevent tread separation. Provider radials are bake tested - a process usually reserved for automotive tires - to ensure that the rubber holds up over time.

Match Mounted and Balanced Trailer Tire Assembly

In an ideal world, tire-and-wheel assemblies would be perfectly round and even throughout. Unfortunately tires and wheels have imperfections that often cause vibrations, resulting in a rough ride and wear and tear on the assemblies, as well as on the rest of your trailer's running gear. Taskmaster helps to solve this problem by match mounting and balancing their assemblies so they're ready to roll when they reach your door.

To do this, Taskmaster uses a laser-guided machine to locate the heavy and light spots of each assembly. They then align the assembly so that lightest part of the tire is near the heaviest part of the wheel. The assembly is then rotated at high speeds to pinpoint the optimal place to apply weights to further balance the tire.

Don't delay your adventures by having to take your trailer to the shop for new tires. Start rolling as soon as possible with easy-to-install, fully balanced tire-and-wheel assemblies from Taskmaster.

Radial Tires vs. Bias Tires

Radial tire vs bias tire graphic

Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.

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"

Excellent trailer wheel and tire! Exactly like the ones on the trailer.


Mounted tires, just what I was looking for for my 1966 Roadrunner camper trailer. Etrailer was more than fantastic, receiving my order 9/18 and having it on my doorstep across the country on 9/21. That’s amazing. Tires were aired up, balanced, and ready to mount. Thank you!


Excellent quality wheel and tire. I installed 4 on a 7x16 enclosed cargo trailer. Look great, smooth and comfortable, handle the load well. After 1 year and 3000 miles, all are holding up well and no issues after going through a Michigan winter.



2 years and all is well. Did a couple of out of state trips hauling motorcycles in an enclosed cargo trailer and these wheels and tires have been very reliable.


Exact match for my utility trailer, mounted ready to travel with a peace of mind.


Great company to work with! Got the exact tires and wheels I wanted.

  • Do Trailer Wheel and Tire Combos Require Balancing
    Our trailer wheel and tire combos do not come balanced nor do they actually require it. There's no noticeable benefit to having trailer wheels balanced and often times the weights just end up bouncing off due to less sophisticated suspension on the trailer so it's not needed.

  • Does Valve Stem Come With Provider 205/75R15 Trailer Tire & 15 Inch Black Wheel
    You do not have to purchase the valve stem separately as it does indeed come with the Provider ST205/75R15 Radial Trailer Tire w/ 15" Vesper Black Mod Wheel # MX37FR.

  • Is An ST205/75R15 Tire Typically 27.13" Tall and 8" Wide?
    I am not sure what brand the tires currently on your trailer are, but the 27.13" height and 7.99" width of the Provider ST205/75R15 Radial Trailer Tire w/ 15" Vesper Black Mod Wheel - 5 on 4-1/2 - LR C # MX37FR you were looking at is standard for this size. Is it possible your tires are a 205/75R14? If that was the case that would explain the 1" height difference. There shouldn't be an issue using these to replace your current tires, but since you mentioned they are 1" taller you will...

  • Wheel Bolt Pattern of 2022 Grand Design Imagine 2500RL
    It looks like the 2022 Grand Design Imagine 2500RL could have come from the factory with either 5 on 4-1/2" hubs/drums (3,500 lb axle) or 6 on 5-1/2" hubs/drums (4,400 lb axle). If you just count the number of lug nuts on the trailer that will tell you which. If it's 5 then yes, the Provider ST205/75R15 Radial Trailer Tire w/ 15" Vesper Black Mod Wheel part # MX37FR will work great for you. If there are 6 nuts, I recommend something like the Provider ST205/75R15 Radial Trailer Tire with...

  • Can ST205/75-14 be Used as Spare for ST205/75-15
    If you were in an emergency situation and your trailer had the ST205/75R15 installed like the # MX37FR that you referenced and you only had the tire size of ST205/75R14 I wouldn't blame you at all if you decided to run it to get that said, would I recommend you set yourself up for that situation? No. I would not, it is important that you run the same size all around and I would say your most ideal situation would be to have a spare that is the correct size like our most economically...

  • Recommended Off-Road Trailer Tire For A 15 Aluminum Wheel
    I do indeed have something for you to check out. The Westlake ST235/75R15 Radial Off-Road Trailer Tire # WST54FR seems to be exactly what you are looking for. This is a rugged radial tire with a D weight rating (2,910 pounds at 65 psi) and an L speed rating (75 mph). We are pretty limited on the wheels we have for this tire, but if you wanted to check out the Aluminum Sendel Series T02 Machined Trailer Wheel - 15" x 6" Rim - 5 on 4-1/2 # AM22653 it would make a nice-looking combo with...
