This Provider ST205/75R15 radial tire gives you strength you can trust on long hauls. With an 8-ply rating and maximum load of 2,150 lbs at 65 psi, it’s built for stability, durability, and heat resistance at highway speeds. The M speed rating (81 mph) keeps things steady when you’re running fast or hauling heavy.
The tire-and-wheel assembly is match mounted and balanced right from the start, so it runs smooth and reduces vibration that can wear components over time. Double steel belts, double polyester cords, and nylon tread-firming overlays work together for even wear and long tread life. It’s a setup that feels solid mile after mile.
The steel modular wheel is protected by an acrylic enamel finish applied over an e-coat primer and zinc phosphate pre-treatment. This finish lasts longer than standard powder coat finishes by resisting chips from road debris and scrapes from curbs. It’s proven with a salt spray rating of more than 1,000 hours, so it stays looking clean in tough conditions.
This Provider radial uses automotive-grade tread with sipes that channel water away for better traction in rain, snow, or ice. The open rib design lets water escape from under the tire instead of trapping it like solid ribs do. Bake testing ensures the rubber compound holds up over time for consistent grip season after season.
Every assembly comes with a 2-year Platinum Plus warranty that includes complimentary roadside assistance. If you ever get a flat, a technician can come change it out with your existing spare any time, day or night. It’s extra peace of mind built right into the deal.
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 Provider ST205/75R15 Radial Trailer Tire in a Load Range D, mounted on this 15 inch Vesper white modular steel trailer wheel with the 5 on 4 1/2 inch bolt pattern. Now, this tire and wheel assembly is ideal for stock trailers, utility trailers, and even campers. We'll start with the steel wheel itself. This is a steel wheel, has the modular design, which is sturdy and corrosion resistant, and when we say modular design, that's the one you can see that has the round holes that go all the way around the wheel. This wheel uses a white acrylic enamel finish to resist chipping and other damage better than the powder coat finishes, and the finish is applied after a zinc phosphate pre-treatment, and it covers an E-coat primer layer.
This does give you excellent corrosion resistance with a salt spray rating of more than 1,000 hours. Now, the stud holds right here, when you go to install this, they are beveled stud holes, this will help keep your wheels securely in place on your trailer hub, eliminates the need for constant re-tightening of your lug nuts. Now, the tire on this is a radial tire, it is constructed with the double steel belts and the double polyester cord, so it is great for highway use. They do use a nylon tread-firming belt overlay to help prevent tread separation, and the tread is an automotive-grade tread design, and it has the sipes on the tread. If you look a little close at the blocks, you'll see these cuts in there, and those are called sipes, and what that does is that'll channel the water away from underneath the tire, helps improve traction during wet, snowy, or icy conditions.
Now, this is a special trailer tire design, it'll couple the strength of a bias tire with the durability and stability of a radial tire. It is created specifically for trailers, it's not intended for use on other vehicles, and this tire wheels assembly does meet the DOT, Department of Transportation specifications, and will exceed your Federal Motor Vehicle Safety Standards. Does come with a two-year platinum plus warranty, which will include complimentary roadside assistance, and that service is available 24 hours a day, seven days a week. Now, this wheel does not come with a center cap, if you do want a center cap, we do sell those separately on our website. You do wanna get a center cap that'll have a diameter of 3.31 inches, that's the diameter of this pilot hole here, and this is where your cap will go through.
Few specs on the wheel, the diameter is 15 inches, the width on just the wheel is six inches wide, the bolt pattern on this wheel is a 5 on 4 1/2 inch bolt pattern. And if you wanna measure that on a wheel that's an odd number of lugs like this one, what you wanna do is pick any hole, let's say this one, and then you're gonna measure across to either this hole or to this hole, either one, but the trick is when you measure it, it's from the center of the starting hole to the furthest edge of the hole you measure to. So on this one, it'll measure 4 1/2 inches, so that means it's a 5 lug, 4 1/2 inch bolt pattern. Does use a wheel lug size of 1/2 inch by 20. Now, the weight capacity in just the wheel by itself is 2,835 pounds.
The tire size, which will be stamped on the side wall, ST for special trailer, 205/75R15, the R stands for radial tire. Section width on this tire is gonna be eight inches, overall diameter from the bottom to the very top when it's inflated is 27.1 inches. This is a Load Range D tire, which means it's an eight-ply rating. Does have a maximum load capacity of 2,150 pounds at 65 psi. And the last thing I do wanna mention, most all the new trailer tires are coming through with a speed rating on them, and where the speed rating is, they'll designate it with a letter designation, and it's usually right after the size, so here's the size tire, and then you'll see two numbers for the load index, and then a letter M. Speed rating M will stand for 81 mile per hour speed rating. But that should do it for the review on this Provider ST205/75R15 Radial Trailer Tire in the Load Range D on this 15 inch Vesper white modular steel trailer wheel with the 5 on 4 1/2 inch bolt pattern..

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?

I bought this as a spare for the camper and forgot about it until I needed it two months later. Its been on the ground for 9 months with no problems. Again, its something I can forget about until my pressure check before a trip.

Thanks for the review William! We're glad the tires arrived as promised and that you're happy with how they look. A restored '94 Starcraft sounds like a fun project, we'd love to see it when you get it on the road. Hope the installation goes smoothly and we appreciate you choosing etrailer!

I purchased these tires for the higher speed rating 81 compared to the tires I replaced that were only rated to 65. Which is below typical interstate speeds. I year later the tires and rims are fine.
