When you’re towing for hours on the interstate or hauling through heat, you need a tire that’s built to run cool and stay strong. The Provider ST205/75R15 Radial Trailer Tire (part?# TR20515D) has an 8-ply rating and a 2,150-lb maximum load at 65 psi. Its M speed rating lets you cruise confidently up to 81 mph—far higher than the usual 65 mph limits found on most trailer tires.
This radial is all about durability. Inside, double steel belts and double polyester cords keep the tread firm under load while helping it wear evenly. A nylon overlay wraps the steel belts to guard against tread separation, and each tire is bake-tested to make sure the rubber stays resilient over time. It’s rated to handle real highway use day after day without breaking down from heat or stress.
Rain, snow, or slush doesn’t have to slow you down. The Provider uses an automotive-style tread pattern with broken ribs and thin sipes that channel water away from the contact patch. That extra grip helps keep the trailer steady and reduces the chance of hydroplaning when pavement turns slick.
Radial cords run 90 degrees to the direction of travel, cutting rolling resistance so the tire flexes easily and runs cooler than bias designs. That means less heat buildup, longer tread life, and better tracking at speed. It’s a simple difference that makes highway towing smoother and more predictable—especially on long hauls or in hot weather.
The TR20515D mounts on 15" x 5", 15" x 5-1/2", 15" x 6", and 15" x 6-1/2" rims. Overall diameter is 27.17" with a section width of 7.99". It meets Department of Transportation (DOT) specifications and exceeds Federal Motor Vehicle Safety Standards (FMVSS), so you know it’s built for real-world towing demands and highway reliability.
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"

Ratings & Reviews
Fast delivery and excellent customer service. This was my first time dealing with etrailer and I will definitely be back in the future.
Customer Service is excellent. Tires arrived quickly without any fuss. Tire is still in terrific condition after one year of normal use.
Great prduct and quick delivery, going to use on my 18 ft trailer. I also got the 10 inch
electric brake assembly for about 22 dollars cheaper than what auto parts stores sell them for.
Please explain to me the reason they are advertised to have an 8ply rating but only have two steel belts and two polyester belts? Tires look fine but haven't road tested them. Please respond to my question via email. Please clear up my confusion on description of advertised ply rating and actual ply rating on the side of the tires?
Tires look fantastic, excited to get them mounted up and to take the trailer out this weekend. Amazing service from etrailer, first time using the site and I’ll certainly be back
These are great tires I have gotten a set for my boat trailer and I liked them so must I ordered another set for utility trailer. etrailer has got to the easiest place to work with there shipping is as fast or faster the Amazon.. I will be back
In the past I had used eTrailer to purchase a hard to find trailer tire rim, so when I needed two new trailer tires, I went there again. I had almost a dozen options in load ratings, type of tire, and of course, price. I found the ones that fit my needs, and chose the 3 to 5 day delivery option. They showed up in two. A lot of options, good prices, and faster than promised delivery. Can't get much better than that!
These tires are way better than the tires I was getting from discount tire. The providers hold up well (better than good year or the hartland tires I was using. ) eTrailer has fast delivery and the same price or less than the big stores.
Excellent, just what I needed to upgrade from load range C to D. Costco mounted, balanced, and inflated with nitrogen for $15.00 each
Tires arrived fast. These tires are an upgrate to my previous load range C tires. I like the 81 M.P.H. speed rating for long hauls on the interstate. These tires will be used on a carhauler. I have used these tires for a year and they have held up well.
They look like good tires, I have not mounted them yet. They are imported, I wish they weren't. I'd pay extra for domestic tires if they made that an option on the website (ie have a country of origin listed). We cannot become totally dependent on offshore suppliers for things as critical and fundamental as tires. I have had very good experience with ALL MY ORDERS from etrailer.
The tire for my utility trailer arrived a few days after I ordered it.
It was just as described, I wanted to make sure it matched the other tire I had ordered from Etrailer last year, and it did.
I had it mounted and its on the trailer and running.
I'm well pleased with the Tire, price and the speedy delivery.
I plan to purchase all of my trailering products for Etrailer.
First time buyer with the company. Website easy to navigate and very informative as to product description, etc. I purchased two of these tires for my motorcycle trailer, my research indicating the best buy for the claimed quality and specifications. They were at my door in 2 days but have not yet been mounted. I am hoping that the alleged quality of these tires lives up to my expectations as I will be hauling $60K worth of bikes approximately 5K miles and don't want any surprises. I will follow this up with with a review after use.
Tire Is exactly what I expected. It'll work great for my 24" enclosed trailer.
Quick delivery a plus in my book. I also order some dust caps with the rubber centers for ease of greasing the shell bearings, doing so also provided me with free shipping .
Thanks
Super fast shipping and great value for the cost
Got my 2 custom aluminum trailer rims with tires today(4-06-17) they were delivered in only a few days-along with new chrome wheel lug nuts and new replacement studs and chrome screw on valve stems -took them to my local [service center] to have them mounted--got back home and installed them on the boat trailer I restored this past summer with the boat on it that I am also restoring--The rims look great. Thanks Katie for all your help with placing my order---I am a repeat customer and will tell all of my friends of the great service I received. Thank You.
Great!!! Fast service as always. Got my tire fast and in great shape!
Happy Holidays Everyone. Received My Provider ST-205/75R/15 Load range D- Trailer tires today. What a Well Constructed Tire twice the weight of the Goodyear Load range C that are on my trailer now I know the increase in load range means it will be a bit heavier, but for the Price of these Tiers I truly didn't expect what I received. Great Buy Great Product. I will check back in after our trip with the new Tiers
I needed a little more tire than the typical biased-ply Class C type for my heavy utility trailer, but didn't want to go up in tire size. I also wanted to go with a radial since this trailer sees mostly all highway usage. I purchased a pair of these tires based on reviews and specs. Tires arrived in boxes which is great because it keeps the sides from being compressed when shipping. IF shipped in shrink wrap or tape, the sides get pulled in making them harder to mount...thanks etrailer for shipping these in the proper manner. Tires have a fresh DOT date and tread looks good. Once mounted and put into use, I will post how they are holding up over the long haul.
Excellent service and delivery. 4 day delivery over a weekend! Trailer tires are mounted and ready for the 1600 mile journey for some florida fishing. Thank you for your advice on the best tires for the job, that were not the most expensive on the list. I will be a returning customer!

Perfect! Best tires yet. Very little wear after over 10,000 miles
They have long wear before replacing!

They do look great, Bruce! Where have you traveled with them since getting them?
Bought 3 of these tires for my 8 foot utility trailer that I use to haul my motorcycles and anything else. I have the older triangle style rims that use the old 205/70 style of tires. The newer 205/75 fit just great on my 15" x 6" rims. Can't wait to go on my next long trip with the trailer and the new tires.

I am still using the same tires I purchased over a year ago. They are working great and dont show signs of needing replacement anytime soon. I should go measure the tread depth and see where they are at. I use the trailer on a weekend basis so they are still plenty good.
Service was great, shipping fast. Tires needed a lot of weight to balance. Wear time will tel?

When a tire is given a ply rating, it doesnt necessarily indicate the number of layers of material the tire is constructed of. As the need for greater fuel economy and the cost of materials rises, the tire manufacturers have gone to using lighter but stronger materials like Kevlar that provide the same strength that would have taken several layers of materials years ago. Fewer layers also means less heat build-up, which is essential for longer tire life.All that really matters is the weight capacity of the tire. For example, the Provider ST20575R15 radial trailer tire Item TR20515D has a 2,150-lb maximum load at 65 psi capacity. With a trailer tire, you have to have it inflated to its max psi in order for the tire to have its full capacity.
