When you’re towing long distances or through summer heat, this radial setup is built to go the distance. The ST225/75R15 tire has an 8-ply rating and carries up to 2,540 lbs at 65 psi. Its radial construction with double steel belts and double polyester cords cuts rolling resistance and heat buildup for a cooler, longer-lasting tread. You can cruise confidently at highway speeds knowing everything meets DOT specs and exceeds FMVSS standards.
No extra shop time needed. Taskmaster match mounts and balances each tire-and-wheel assembly before it ships. A laser-guided process aligns the lightest part of the tire with the heaviest part of the wheel, then adds weights for a smooth finish. That means less vibration, less wear on your running gear, and a balanced feel from mile one.
Rust and road damage don’t stand a chance against this wheel’s durable silver acrylic enamel finish. Applied over a zinc phosphate pre-treatment and e-coat primer, it resists chipping and outperforms powder coat in long-term protection. It’s been salt spray tested for more than 1,000 hours, so even in wet or coastal conditions, the steel wheel holds its shine and strength.
The Provider radial’s automotive-grade tread isn’t just for looks—it’s engineered for traction. The ribs are broken up to let water run off to the sides, while thin sipes cut into the tread channel water away from contact points. This design keeps rubber on the road in rain, snow, or icy patches, offering better grip when the weather turns.
Every detail helps keep your setup secure. Beveled stud holes let the wheel seat firmly on the hub so lug nuts stay tight without constant retorquing. The 15" x 6" steel wheel with 5 on 5" bolt pattern, 3.31" pilot diameter, and 0 offset is rated for 2,830 lbs—plenty of margin for heavy loads without flexing or fatigue.
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.
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).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this Taskmaster Provider ST225/75R15 Radial Trailer Tire in a load range D and it's mounted on this 15 inch silver modular steel trailer wheel with the five on five inch bolt pattern. Now this tire wheel assemblies ideal for stock trailers, utility trailers, and even campers. Now the new feature on this assembly, what's nice is this tire is match mounted and then balanced to the wheel for ride comfort and durability and match mounting of tires and wheels, basically it's a process in which the tire's installation position on the wheel itself is specifically selected to minimize the final force of imbalance which is basically the amount of weight used to balance it. The method to match mounting is they align the tire's lightest spot with the wheel's heaviest spot and that's to eliminate most of the radial force that can cause the tire and suspension wear. Then when they do the final balancing, it's done by applying weight to specific spots on the front and the back of the wheel to eliminate any chance of uneven wear vibration.
Just to show, you can see here's where they put the weight on the front and if we spin it around you'll be able to see where they put the weight on the back so it gives you a balanced tire wheel. Now on the wheel itself, they do use a silver acrylic enamel finish. This will help resist chipping and other damage better than your powder coat finishes. The finish is applied after a zinc phosphate pretreatment and then it covers an E-coat primer layer. Does give the excellent corrosion resistance.
Has a salt spray rating more than a thousand hours and they do use beveled stud holes on here where your lug nuts go to help keep the wheel securely in place on your trailer hub. Eliminates the need for constant re-tightening of your lug nuts. Now if you notice, this wheel does not come with a center cap. If you do wanna purchase them, we do sell them separately. You do wanna make sure to get a center cap that'll have a diameter of 3.31 inches.
That's the diameter of the pilot hole right here and that's where your center cap will go through when you install it. Now the tire on this is a radial tire. It is constructed with double steel belts, double polyester cords for nice long life. It's great for highway use and they do use a nylon tread firming belt overlay around the tire to help prevent tread separation. The tire is stamped as an ST tire which means special trailer tire, has the sturdy side wall so they can handle heavy loads.
It's created specifically for trailers. It's not intended for use on any other vehicles. Now this does also offer a two year platinum plus warranty which does include emergency tire change service and other benefits. And this assembly does meet the DOT, Department of Transportation specifications and it will exceed federal motor vehicle safety standards. Just to go through a few specs on the wheel first. Diameter on the wheel is 15 inches, width on just the wheel by itself six inches wide, bolt pattern we mentioned is five on five inches. And if you wanna measure that on a wheel that's a odd number of lugs like this one is five lugs. What you'll do is just pick any hole like this one but then you'll measure across from this hole to either one of these holes. But when you measure it, it's from the center of the starting hole to the furthest edge of whichever hole you measure to. On this one, that measurement will be five inches. So it's a five lug five inch bolt pattern. The wheel lug size used on this is a half inch by 20 and the weight capacity on just the wheel is 2,830 pounds. Tire size will be stamped on the side wall, ST for special trailer 225/75R15. R lets you know that it is a radial tire. Section width, 8.8 inches and the overall diameter from the bottom to the top when it's inflated is 28.3. This tire is a load range D which means it's an eight ply rated tire. Has a maximum load capacity of 2,540 pounds at 65 psi. And one of the last things I do wanna mention is they now come with a speed rating on the trailer tires and that's stamped on the sidewall by a letter designation. And where you'll find that is right after the size of the tire we went over, you'll see two numbers for the load index and then the letter M. Speed rating M will mean this has an 81 mile per hour speed rating. But that's gonna do it for the review on this Taskmaster Provider ST225/75R15 Radial Trailer Tire in a load range D mounted on this 15 inch silver modular steel trailer wheel with the five on five inch bolt pattern.

Perfect fit. Quick delivery. Excellent customer service.
Thank You
It's still the spare.
Nice Wheel and tire combo. They look really nice on my utility trailer. Shipping was quick.
Heavy duty rating looking forward to see how well it holds up.
The 2 Provider Tires on Vespar rims are in excellent condition, mounted good and look in excellent condition.
They both arrived on time without damage, and customer service people were taking care of me by being upfront honest and respectfull.
Good job everyone at etrailer!
Etrailer.com delivered radial trailer tires FAST.
Delivered to my door, accurate description, fully inflated, ready to put on trailer.
Great shopping experience. Thanks etrailer, and thanks Joshua B for the follow-up.
Bought it for a Spare tire. Tire was made Oct.2024 and I got the wheel/tire May 2026. No worries….. it’s a spare tire.
Great product selection and wonderful customer service. I especially liked the frequent updates on my order status.
Light, sturdy feeling, perfect pressure straight out of the box. Honestly this was my first time ordering any kind of tire online so i was a bit paranoid. But the vehicle selector narrowed down the search to this beauty. Fits like a glove on my old 2005 jayco jay series. while its too early for me to rate its longevity, i find the product feel reassuring.
Delivered in two days, changed out for tires in about an hour, rolling safe and looking good!
When the tires arrived, the hubs had a few stretches on them which I assume it from mounting the tires. I installed them and drove around the block. Even though it was a short drive, they seemed to be a much better upgrade than the bias ply tires I had on the trailer.
I also should add that I bought these because of the highway rating as I will be hauling my motorcycle to NY this summer.
On the first trip with these tires and wheels, All wheel weights broke off. Will have to have these balanced again. Tires and wheels are as expected
UPS driver put the tire box at my back gate and was very kind to do so. I’ve ordered 5 new tire/rims for an Alaska trip and and a spare for my cargo trailer in the past. This tire will be a spare on my new trailer.
I previously had ordered the incorrect wheels and tires. When I called to request a new order for the correct wheel/tire combination and to place a return request for the initial order, I was provided excellent, knowledgeable, and courteous service from Paula. Return was easy, and the second order was received exactly when stated. I will definitely be ordering again from etrailer.
Excellent looking wheels and tires! The wheels are flawless - no scratches or chips.
I put these on a small utility trailer that I expanded for hauling my kayak and jon boat. The gross weight is very light so I reduced my tire pressure to about 75psi and took the trailer for its maiden test drive this past weekend. Handles great in town. It did 75-80mph on the highway no problem.
Many thanks to Sarah S for her assistance with my order. I could not be happier right now.
Side note, I also installed the Counteract Balancing beads (CA68VR).
Nice tire on a good looking rim!
I’m a repeat customer with etrailer. As always, great service and timely communication on order status and shipping.
I had accidentally ordered the wrong size tires and William was very helpful in getting them returned as well as sending me the correct tires. Very pleased with the overall quality and efficiency and pricing.
