Features to know about

Ready for Real Road Miles: Load Range E with 81-mph Speed Rating

Built for the kind of long hauls that rack up serious miles, this setup runs cool and steady at highway speeds. The Provider ST225/75R15 radial tire carries a Load Range E, 10-ply rating with a 2,830-lb max load at 80 psi. Its double steel belts, double polyester cords, and nylon tread-firming belt overlays hold up through heat and heavy weight. The M speed rating (81 mph) means it’s ready for highway use without worry about excess buildup or tread fatigue.

Smooth Ride from the Start: Match Mounted and Balanced Assembly

You don’t need to make a shop stop before hitting the road. Each Taskmaster tire-and-wheel assembly is match mounted and balanced at the factory using laser-guided machines to align heavy and light spots for smooth rotation. That balance cuts vibration and reduces wear on both the tread and running gear, giving you a stable, steady feel right out of the box.

Built to Last Through Weather: Rustproof Aluminum Wheel with Glossy Coating

Salt, spray, and road grime are no match for this wheel’s corrosion resistance. The 15" x 6" aluminum construction is durable, lightweight, and rustproof, topped with a glossy enamel coating that resists corrosion over time. The bold black-and-machined Trinity design gives it a clean, modern look that holds up as well as it looks.

Confidence in Wet or Icy Conditions: Automotive-Grade Radial Tread Design

The Provider tread takes a cue from passenger tires with ribs broken up by sipes that channel water away from the contact patch. That design helps traction on wet, snowy, or icy roads while reducing the risk of tread separation thanks to bake-tested rubber that holds its integrity over time. With a 10/32" tread depth and tread wear bars molded in, it’s easy to keep an eye on remaining life between trips.

Extra Assurance on the Road: Platinum Plus Warranty with Roadside Assistance

Along with DOT compliance and construction that meets FMVSS standards, this combo includes Taskmaster’s Platinum Plus warranty coverage. For two years it provides complimentary roadside assistance—if you get a flat, a technician will come change it using your inflated spare—and includes additional warranty benefits covering both tire and wheel for long-term peace of mind.

Determining Bolt Pattern

1. Count the lug holes

Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).

Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug

2a. For even lug counts (4-lug, 6-lug, 8-lug)

Measure from the center of one lug hole directly across to the center of the hole opposite it.

Center to Center
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"

2b. For odd lug counts (5-lug)

Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).

Center to Outside Edge
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Video Transcript for Review of Taskmaster Trailer Tires and Wheels - Tire with Wheel - TA56AR

Hi everyone, Steve here with etrailer.com. Let's take a look together at our Taskmaster Provider ST225/75R15 radial tire with the nice black machined Trinity wheel with a five on four and a half inch lug pattern. Now folks, this wheel and tire combo is gonna be great for your campers and trailers. It is made and assembled for trailers, so please never use it on a vehicle. It's just not designed for that. Now each tire and wheel assembly is gonna come pre-matched and balanced from the factory.

That's gonna minimize vibrations, reduce wear and tear on your trailer. Now as you know, trailers are gonna face a variety of weather conditions and good traction is key. So with Taskmasters, they give you an automotive grade tread and as you can see here, it's got sipes on the side that's gonna channel water away, pushing water away, giving you a better grip on the road no matter what mother nature throws at you. Now again, this is an ST225/75R15. So the wheel is a 15 inch diameter, that's bead seat to bead seat and it's six inches wide without the tire on there.

Now the pilot hole is a 3.19 inch hole, but remove the center cap, that's that 3.19. It does come with the nice center cap here and it comes with a five lug pattern. Again, a five on four and a half inch lug pattern. Now the outer diameter of this hole assembly is actually 28.3 inches in diameter and the section width from the side is 8.9. It's a load range E, which means it's a 10 ply tire and the max speed is an M and that is 81 miles per hour.

Now on the tire, after all the information as far as the tire size, you usually have another couple of numbers. And then that last letter dictates that speed rating, which again is 81 miles per hour. The wheel capacity is 2,835 pounds and the whole assembly here can hold that weight easily. Well folks, I think that's gonna wrap it up for our quick look together at this Taskmaster Provider with the included center cap on the black machined Trinity wheel. Folks, I'm Steven, thanks so much for your time.

Thanks for watching. Have a good one.

The tires are all I hoped for and then some. They have super deep treads most trailer tires don't have the deepest tread.

I am very pleased with this wheel and tire package. My wife said they make our old camper look younger! These tires and wheels seem to be very high quality. Time will tell how they wear and hold up, but so far, I am very pleased!



by:

E-Trailer is quick and a nice company. Will continue to shop here again and again. Tires were perfect for my old GeoPro travel trailer. My only concern was the tires are already two years old. (0824) and bought the last week in 2025. Overall, very happy!



by:

Just put 2500 miles on this set of tiers in 90+ degree heat with absolutely terrible road conditions and have no complaints! Very good looking wheels and tires and like the 225 on 15" wheels. Good amount of sidewall ans still worked well in the place of 205 tires on 4" drop axles on an enclosed harley trailer. etrailer even new what lug nuts i needed. Great service!

  • Recommendation to Replace 205/75R14 Tires on Mallard Camper
    Hi Jeff! So the only combo with the 5 on 4-1/2 inch bolt pattern we have that provides that Load Range E rating is the Taskmaster Provider # TA56AR. It doesn't look like that tire is available by itself, either. This would certainly give you more than enough capacity with its 2,830 pound rating, but other than extra peace of mind (which is indeed valuable), I'm not sure you really need to upgrade. The Provider # A225R645WM you were looking at is still going to give you a combined load...

  • Availability Of Goodyear Endurance ST225/75R15 Tire Mounted On 5-Lug Aluminum Wheel
    Hello John, thanks for reaching out. Sadly, we do not offer that size Goodyear tire on a 5-lug wheel. We can offer you a ST225/75R15 tire on a 5-lug aluminum wheel, but it would not be a Goodyear. Our selection of Goodyears is pretty limited at the moment. If you want to look into other options, what I recommend is the following: - Taskmaster Provider ST225/75R15 Radial Tire with Black Machined Trinity Wheel - 5 on 4-1/2 # TA56AR

  • Taskmaster Rambler ST225/75R15 Load Range E on 5-on-4.5 Availability
    Hey Randy, I dug into this for you and I’m not seeing that Taskmaster offers the Rambler ST225/75R15 Load Range E on a 5 on 4-1/2 bolt pattern. That specific Rambler setup is only available on a 6 on 5-1/2 wheel, part # TA98GR. I know that’s probably not what you were hoping to hear, especially when you’re trying to keep everything matching and bolt-on simple. The good news is we do have a really solid option that checks all the boxes you’re after in that same size, load range, and bolt...

  • Where Are The Taskmaster Wheels And Tires Made?
    Hello Virgil. The Taskmaster wheels and tires like the # TA56AR combo are manufactured in China. We cannot guarantee a specific date code for our tires. We typically move tires pretty quickly. We receive shipments regularly and we make sure to rotate our stock to prevent old stock from getting sent out. Also, our tire warehouse is climate controlled and tires do not age in proper storage. The warranty would start when you receive them. Also note that with the current state of the supply...

  • Can I Switch My Trailer Tires & Wheels to a Larger Size?
    Hi Davy, It may be possible to switch to larger tires and wheels, but you'll need to do some measuring to make sure you have clearance before you do. A ST225/75R15 tire and wheel is generally 2.2" taller overall and 0.8" wider than your current ST205/75R14 tires. For a trailer, you generally want at least 3" to 4" of clearance from the top of the tire to the bottom of the wheel well and 1" to 2" of clearance from the inside edge of the tire to the frame rail. Not having enough clearance...
