When you’re hauling at speed or covering long stretches of road, this radial tire-and-wheel combo keeps things steady. The Provider ST225/75R15 tire has a 10-ply rating and handles up to 2,830 lbs at 80 psi, with an M speed rating of 81 mph. Double steel belts, double polyester cords, and nylon tread overlays help resist tread separation and heat buildup, so it stays reliable mile after mile.
No need for a shop visit before your next trip. Taskmaster match mounts and balances this assembly using a laser-guided process, aligning the lightest part of the tire with the heaviest part of the wheel and fine-tuning it with precision weights. The result is a smoother ride that reduces vibration and wear on your running gear from the first spin.
Moisture, salt, and road grime don’t stand a chance against this wheel’s layered protection. Each steel wheel is pre-treated with zinc phosphate, then coated with an e-coat primer and finished in silver acrylic enamel. This finish performed for more than 1,000 hours in salt spray testing and resists chipping better than typical powder coat finishes, keeping the wheel looking sharp season after season.
This Provider radial uses automotive-style tread with sipes that channel water away from the tire surface for better contact on wet, snowy, or icy roads. The tread pattern offers smooth highway traction while helping prevent hydroplaning. Bake testing ensures the rubber compound holds up over time, giving you lasting performance whatever the weather brings.
When things don’t go as planned, it’s good to know coverage is built in. This assembly includes Taskmaster’s 2-Year Platinum Plus warranty with complimentary roadside assistance for flat tire changes—available 24 hours a day, 7 days a week. It’s practical assurance to help keep your plans on track wherever you travel.
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 E, mounted on this 15 inch Vesper Silver Modular Steel Trailer Wheel with the six on five and a half inch bolt pattern. Now this tire and wheel assembly's ideal for stock trailers, utility trailers, and even campers. Now on this assembly, the tire is match mounted and balanced to the wheel for ride, comfort, durability. And match mounting of tire's and wheels is a process in which the tires installation position on the wheel is specifically selected to minimize the final force of imbalance.
The method of match mounting is to align the tire's lightest spot with the wheel's heaviest spot to eliminate most of the radial force that can cause tire and suspension wear. Then the final balancing is done by applying weights to specific spots on the front. You can see them right here on the front. And if we spin it around onto the back, you'll be able to see it there on the back. This will eliminate any chance of uneven wear vibration.
The wheel itself is a steel wheel. It is a modular design, and by that we mean it has the round holes all the way around. It is sturdy and corrosion resistant. They do use a silver acrylic enamel finish on it, which will resist chipping and other damage better than your powder coat finishes. And the finish is applied after a zinc phosphate pretreatment, and it covers an e-coat primer layer.
Does give the excellent corrosion resistance. Has a salt spray rating of more than a thousand hours. Now the measurement on the wheel, the dimer is 15 inches. The width on just the wheel is six inches wide. Bolt pattern is a six on five and a half inch bolt pattern.
And if you wanna measure that bolt pattern on a wheel like this that's an even number of lugs, it's pretty simple because the lug holes are directly across from each other. So just pick any hole, let's say this one. Measure from the center of the starting hole to the center of the hole right across from it. On this, it'll measure five and a half inches. So that means it's a six on five and a half inch hole pattern. The wheel lug size this uses is a half inch by 20. And the weight capacity on this wheel is 2,835 pounds. Now if you notice, it does not come with a center cap. If you do want a center cap, we do sell those separately. You do want to get one that'll have the same diameter as this pilot hole, because when you install your cap it'll go through this hole, the diameter of this pilot hole is 4.25 inches. Now the tire that's on it, it is a radial tire. Means it's constructed with double steel belts, double polyester cords for a nice, long life. It is great for highway use, and they do use a nylon tread firming belt overlay around the tire to help prevent tread separation. Now we mentioned, this is an ST tire, which is a Special Trailer tire. Has sturdy sidewall so that it can handle heavy loads. It is created specifically for trailers. It's not intended for use on other vehicles. The tire size, which will be stamped on the sidewall. ST, for Special Trailer, ST225/75R15. The R means it's a radial. So the section width on this is 8.8 inches. Overall diameter from the bottom to the top where it's inflated 28.3. And this is a load range E tire, which means it's a 10 ply rated tire. So it has a maximum load capacity of 2,830 pounds at 80 PSI. Now they do offer a speed rating on this and it is stamped on the sidewall, but it is stamped in a letter designation. And where you'll find that it's right after the tire size, you'll see two numbers for the load index. And then you'll see the letter M. Speed rating M will mean this is an 81 mile per hour speed rated tire. This whole assembly does meet the DOT, Department of Transportation specifications, and it will exceed federal motor vehicle safety standards. One last thing is they do offer a two year platinum plus warranty, which will include emergency tire change service and other benefits. But that's gonna do it for a look at this Taskmaster Provider ST225/75R15 Radial Trailer Tire in a Load Range E, mounted on this 15 inch Vesper Silver Modular Steel Trailer Wheel.

Hi, I needed a spare for my motorcycle trailer so I purchased a matching set. Now I can switch between silver and chrome depending on my hair. Very efficient shipping (boxed). Thank you.
Perfect fit, Perfect Service. Perfect communication. Couldn't ask for a better company. Ordered spare tire the exact wheel and tire was in stock and shipped to order right away. Knew exactly the transit complete visibility and ETA. Tire was boxed up and was delivered with no damages.
Just got the tires and rims. They look good but what year were this tires mfg. DOT 10U. Does that mean they were made in 2010? I sure hope not!!
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.
I was very disappointed to see that only the outside of my wheel was painted white. When mounted on my motorcycle trailer, both sides of the wheel are clearly visible. Unbelievable that the miniscule savings afforded by skipping this step is considered justified. I am now stuck, of course, because the delay to exchange or return it would be unacceptable.
If this is indicative of the quality I should expect from etrailer, this will be my last order.
All arrived in good condition. I was pleased that the wheels were balanced although it didn't appear that way on your website. These 81 mph-rated tires are being used to upgrade 8" tires on a small trailer to haul a Cushman Eagle at Interstate speeds
Exactly what I needed at a fair price and on time. They had the same wheel tire combo that I'd ordered a couple years ago which is great.
The tires were shipped faster than I thought. I just got here and are about to go on my trailer
Good quality, fast free shipping, prompt delivery. Very happy
Nice Wheel and tire combo. They look really nice on my utility trailer. Shipping was quick.
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.
Tires came as promised. I have not installed them as of yet, but i really like the look. They should look great on my restored 1994 Starcraft popup. Can't wait to get it on the road again. Hopefully the end of July.
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.
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
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.
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.
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!
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).
