When you’re running long distances or carrying serious weight, this setup has your back. The ST225/75R15 radial is Load Range E with a 10-ply rating and a maximum load of 2,830 lbs at 80 psi. Rated for 81 mph, it’s made for highway use with double steel belts, double polyester cords, and nylon overlays that help prevent tread separation. It’s all DOT-compliant and built to handle heat and high speeds mile after mile.
Skip the hassle of shop balancing. Taskmaster match mounts and balances each Provider tire and Vesper wheel using laser-guided equipment so it rides smooth from the start. The lightest part of the tire is paired with the heaviest part of the wheel, then fine-tuned with weights for a balanced feel that reduces vibration and wear on your trailer’s running gear.
Corrosion doesn’t stand a chance here. The steel mod wheel is finished with an e-coat primer, zinc phosphate pre-treatment, and durable white acrylic enamel that resists chipping better than powder coat. It’s been salt-spray tested for more than 1,000 hours, so it stays looking clean and solid even after seasons of use in tough conditions.
This Provider radial uses automotive-grade tread with sipes that channel water away from the contact patch for improved traction in wet, snowy, or icy conditions. Compared to standard trailer tread, the broken rib pattern helps shed water faster while maintaining stability under heavy loads. Each tire is bake tested to ensure the rubber compound holds up over time.
If a tire goes flat, you’re covered. The included 2-Year Platinum Plus warranty provides 24/7 roadside assistance that sends a technician to install your inflated spare on the spot. It’s extra assurance that keeps you rolling when plans don’t go as expected.
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"

Hi, this is Scott with etrailer and today we're gonna be taking a look at our replacement rim and tire combination for our trailer. What we have here today are our Provider radial STs, and these are gonna be trailer-specific tires only. These aren't gonna be able to go on any other kind of vehicle and the ST means special trailer, so what you got there on the ST. Now these are available on different sizes, bolt patterns, load ratings, so make sure you get the right one for your trailer. You can also get them in black, white or a silver finish. As far as our speed rating, a lot of these tires now come with the speed rating on them and that's gonna be a a speed rating of M on this one, and that's gonna be right around 81 miles an hour for the speed rating.
That's going to be your maximum speed that you're gonna want to go with this tire. Now we have our trailer in here now and we did some brake work on it and we did some bearing work on it and we did take a look at our old tires that we inchesre on there. We decided, you know what, why don't we just go ahead and update them while we're at it. That way we know everything was all done at once and everything's all freshened up. And as far as the combination goes, it comes with a really nice wheel, it has like a zinc coating on the underneath of all of this coating along with our e-coating and then our acrylic finish on the wheel itself.
That's gonna give it a really nice corrosion resistance and rust resistance. Now another thing nice about this tire, it is gonna be steel belted radial, so it's gonna hold up really good. As far as the tread pattern goes, it's gonna have siping in here and what that's gonna do for you is it gets raining a little bit, the rain's gonna get in there and break up and it's going to get squished out and run out these channels here. So it's gonna keep your tire nice and stable on the road in any kind of heavy rains, it's not gonna hydroplane back there when you're pulling it down the road. So that's really nice.
Another nice thing about these is this one comes pre-balanced, so it is already weighted and balanced, so it's gonna give you a smooth ride right off the bat. So if you got a trailer that's back there kind of bouncing around when you're taking it down the road, this is gonna help smooth that out where you're gonna get rid of all that rattling and all that stuff and give you a lot smoother ride. As far as finding out what you need for rim and tire combination, the easiest way to do that is gonna be take a look at the the tire size that you have on your trailer already and you just want to kind of stick within that, your size and your load rating there. In order choosing one as well, you wanna make sure you go with the right load rating for it. So this one's gonna be a C and it's gonna be a six-ply tire and it's gonna put us right around in the 1800 pound range each side.
So that gets us right around our 3,500 pound axle rating for this one. You are gonna wanna find out what size axle you have for yours, and that way you can kind of go by your load rating with that. But for this one, another thing you're gonna have to check out is what your lug measurement is. So on this one we have a five, which is our five lug, and then we have a 4 1/2. So we're gonna go from the edge of this here to the center of this one here, and that's going to give us 4 1/2 from here to here. Another thing you can do is you can use this indexing type ring and what it's gonna do is you can pop it on there and that'll verify that you have the right size. And this one we're showing 4 1/2. These are really nice to have if you have multiple trailers and you gotta replace tires quite often on those, say you're running a, you know, like a lawn service or something like that, this is nice to have, that way you can just see, if you have different trailers, what your bolt pattern is. Now this one does not come with lug nuts, we do offer them here at etrailer. You just gotta figure out what size that you have as far as lug nuts. With ours here, our lug nuts look like they're pretty good, so we're just gonna go ahead and keep the ones that we had on here and just reuse those. All right, with that all said, we're just gonna go ahead and get our wheel and tire installed. We will put our lug nuts on finger tight for now. After we get 'em all put on there finger tight, we'll come back through with either a four-way or an impact set on light, like one, or something like that. Just get 'em snugged down and then after we get our trailer sat back down on the ground, we'll come back through and we'll go ahead and set 'em down to the torque rating. Your torque rating, you want to get a check on that for whatever your stud size is. You'll be able to find out what your torque range is for those. Now we snug these down. We're just gonna go on a star pattern, here, we're gonna hit here, here and then we're gonna go over here, over here and here. That way, it all seats up nice and even. Now that we have it on the ground and we have both sides of our wheel chocked, we'll just go ahead and torque 'em down. (torque wrench beeps) Now that we have all of our wheels all torqued down and everything's tightened up, go ahead and check your tire pressures and make sure they're where they're supposed to be on both sides. I'd say drive it about 50 miles or so. Let everything settle in and then recheck 'em for torque and check your tire pressures and everything will be good to go. Hopefully this video will help you make the right decision on your Provider wheel and tire package for your trailer and hopefully it helps you figure out the right size. I'm Scott with etrailer. Thanks for watching.

excellent service.
I’m happy with your service and communication throughout the order process.
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
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.
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.
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.
The tires were shipped faster than I thought. I just got here and are about to go on my trailer
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.
Good quality, fast free shipping, prompt delivery. Very happy
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.
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.
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).
Fast shipment and exactly as listed
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

I am shocked to hear they broke off Larry. I have never heard of an issue like this before. I would like to reach out to the manufacturer but need to know a little more information. What kind of trailer did these go on, and what is the weight?
