Provider Radials with Automotive-Grade Tread

Provider Tread Vs Standard Tread

Unlike standard trailer tire tread, which has solid, continuous ribs, the automotive-grade tread on these Provider radials has ribs with breaks. These breaks allow water to run off to the sides. The Provider tread also has sipes. Siping is a process in which thin grooves (or sipes) are cut into the rubber of the tire. The grooves channel water away from the tread so that the tire makes better contact with the road. Both of these features greatly improve traction during wet, snowy, or icy conditions.

Provider radials are constructed with double polyester cords and double steel belts for increased durability and endurance. A protective layer of nylon is wrapped around the steel belts to help prevent tread separation. Provider radials are bake tested - a process usually reserved for automotive tires - to ensure that the rubber holds up over time.

Radial Tires vs. Bias Tires

Radial tire vs bias tire graphic

Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.

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.


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.


Matches the tire/wheel combo I bought. I should be good to tow 4 wheeler for deer season.


nice quality. I was thankful that I found a location for that certain size.


ST225 were ship rather than ST205's I assume a simple human mistake, lets see if return process and requested product is provided in a timely manner


Thanks Susan for the all the help choosing the right tires for my 14x7 trailer. Feels so much better than the original tires and safer driving at speeds. Great tires and came when you said that they would. Thanks again.


I called on a Sunday not expecting to reach anyone but Nicole answered the phone and was very helpful. I ordered the tires and was told they were backordered til 6/2 but I received the order for 4 tires today! (2 weeks ahead of expected time). I haven’t had the chance to get them installed yet but looking forward to see how they hold up. Very pleased with the service and communication. Will definitely order from e trailer again


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


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.


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


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.


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


Customer Service is excellent. Tires arrived quickly without any fuss. Tire is still in terrific condition after one year of normal 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 .



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.


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.


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.


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.


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!


Great service


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?

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.


Excellent, just what I needed to upgrade from load range C to D. Costco mounted, balanced, and inflated with nitrogen for $15.00 each


Put 4 of these on my 8.5x20 enclosed car trailer and 2 on my 5x8 trailer a year ago. They’re all holding up great so far! Hope to get a long time out of these for the price


A delay in receiving shipment and reason were tires not in stock, as was informed by Tim, but the tires were later received individually boxed - all 6 total. Tires are a good quality as expected with class D rating and manufactured dates are currant (not years old).
Many reasons why my family buys from and yet we find another.

  • Trailer Tire Recommendation to Replace Tire Size 205/75-15
    Any tire size that starts with the letter P should not be used on a trailer. If this is a trailer application, I'd recommend you stick with a trailer rated tire in the same size like the part # TR20515D which will fit and work well. It has a capacity of 2,150-lb maximum load at 65 psi and has a higher speed rating of 81 mph.

  • Load Range D Taskmaster Trailer Tire Recommendation Size 205/75-15
    With trailer tires you have to run them at their max psi rating at all times otherwise you diminish the weight capacity of the tire and will cause it to create excess heat which will cause failure. The Taskmaster Tire part # TR20515D that you referenced would be a great option as it is the correct size of 205/75-15, is a Load Range D, and has a higher speed rating of 81 mph. It requires 65 psi all the time.

  • Recommendation to Replace Load Range C ST205/75R15 Tires on Jayco Jay Flight Trailer
    When determining if the tires on your Jayco Jay Flight are appropriate, you will want to make sure that their combined load capacity meets or exceeds the total loaded weight of the trailer. For this loaded weight, you will want to go by its GVWR, which you stated as being 8,500 pounds. The current Load Range C tires on your trailer will give you a combined capacity of 7,280 pounds (1,820 x 4). Since this falls quite a bit short of the trailer's possible loaded weight, I definitely recommend...

  • Troubelshooting Tire/Wheel Leak on a 5th Wheel Trailer
    If you are saying that you have installed the same tire on 2 different wheels and they leak then it sounds like the tire itself has a leak. You can test this by putting soap and water in a spray bottle and spraying the tire down. The location of the leak will bubble up as air escapes. It also sounds like you may have a tandem axle trailer and you have 2 of the same tire but each are mounted on different wheels and both of them are leaking. This sounds like you may have run over something...

  • Troubleshooting the Outside Edge of Rear Tire on Tandem Axle Travel Trailer Wearing Differently
    Tire wear on the outside of one of the rear tires on your tandem axle trailer is most likely due to incorrect tire pressure or sway. If you keep your trailer tires inflated to their max psi when cold then your tires will have the best chance of even wear and you can rotate the tires as needed. If both rear tires are wearing on the outside, then that would be an indication that the weight on that rear axle was not significant enough to straighten out the axle when under load as most axles...

  • Recommended Tire for Upgrading Trailer Tires to Radials.
    Moving up to radial tires will increase the tread life as long as there are no issues with your axles that might be causing the premature tire wear. The steel rims can be reused to mount radial tires. However, inspecting the rims for any damage should be the first step before mounting a new tire. With that in mind, I recommend Taskmaster's Provider ST205/75R15 Radial Tire # TR20515D. These tires are rated Load D at 2,150 lbs at 65 psi. On both axles the total capacity would be 8,600...

  • USA Made Trailer Tire in Size ST205/75-15
    The Taskmaster tire part # TR20515D that you referenced was made in China, even though they are not made in the USA, they are a great tire with great customer satisfaction. These have a weight capacity of 2,150 lbs at 65 psi and a speed rating of 81 mph. I attached a review video for more info for you to check out as well.

  • Can Trailer with Radials use a Bias Ply as a Spare
    If you had a matching trailer tire size to what is on the trailer but instead it was a bias ply and the trailer had radials you would be okay to get home in an emergency, but it wouldn't be an ideal solution. Instead I would recommend you go with a radial in that size like # TR20515D instead on your spare to allow to match the construction perfectly.

  • Can 205/75-15 Sized Trailer Tires be Used to Replace Size 235/70-15
    Yes, since all the rims are 15 inches 205/75-15 sized tires will fit on all of them. However, if the rims aren't all the same you may want to look at replacing them as well so that everything matches. Our most popular 205/75-15 sized tire is the Taskmaster Provider # TR20515D. They're rated for a maximum weight of 2,150 pounds per tire at 65 psi. They also have a speed rating of 81 mph which is higher than a lot of trailer tires.

  • Radial vs Bias 205/75-15 Tires on Horse Trailer
    The "D" on your new ST205/75D15 tires stands for diagonal or bias ply construction, meaning that the tire's body plies crisscross. A radial tire's plies like what you previously had on your trailer branch out from an imaginary center of the wheel. As you mentioned in your question, a radial tire's construction will allow for it to run cooler than a bias ply tire. This is especially true when the tire is under a heavy load. The reason this is important is because excessive heat is the primary...

  • Tire-to-Wheel Mounting Based on High/Low Spots on Tire
    Tires can be marked for their low spot and high spot (the lightest and heaviest points) with a range of colors but on a tire that has a red dot that point should be aligned with the wheel valve stem. Red denotes the high/heavy spot.

  • Trailer Tire Recommendation for Size 205/75-15
    The tire I would recommend for the size you listed is the part # TR20515D which is a radial tire in the size 205/75R15. What's really great about this tire is that it has a speed rating of up to 81 mph.

  • Trailer Tire Recommendation to Replace 205/60-15 Tire Size
    I would go with the tire size the closest to what you have on the trailer so that you know there wouldn't be any clearance issues at all. Good call in getting rid of the passenger vehicle tires though. That could get dangerous if left on. The part # TR20515D would work well for you. The price isn't bad and the speed rating is 81 mph which is much higher than most trailer tires. This will fit your rims easily. No need to replace them if yours are still good.

  • Recommended Radial Tires Over Bias Tires for 2010 Covered Wagon Trailer
    For your 2010 Covered Wagon Trailer, I do recommend you upgrade to radial tires. My recommendation is the Provider ST205/75R15 Radial Trailer Tire - Load Range D # TR20515D. The reason for upgrading is that radial tires have belts or cords that are positioned at 90 degrees from the direction of the tire rotation. This prevents the cords from making contact with each other when the tire flexes which allows them to decrease rolling resistance heat better than bias tires. This allows them...

  • Tire Pressure for 205/75/15 Radial Trailer Tires
    Without knowing what specific tire you have I would not be able to give you any definitive answer, though I can tell you that each of the 205/75/R15 load range D tires we carry, such as the Provider # TR20515D have a maximum load capacity of 2,150 lbs at 65 psi.

  • Do Trailer Wheels have Pressure Rating for Load Range D Tire Size 205/75-15
    Typically with trailer wheels and tires it's not the actual wheel that has a psi limit that becomes an issue. Normally it's the valve stem installed in the wheel that is the issue (if any at all). The part # TR20515D is a Load Range D ST205/75R15 tire that has a 65 psi max pressure that must be in the tire at all times. That shouldn't be an issue at all for what you have in the wheel currently as that's pretty low relative to some of the tire pressure ranges.

  • Trailer Tires With Size Similar to 215/60R15 Tires

The closest to that for a trailer tire is a ST205/75R15 tire which measures 27.1" in diameter, is 8" wide and also fits 15" wheels. For this size trailer tire the best available is the Taskmaster Provider # TR20515D. This is a load range D tire that has a maximum capacity of 2,150 lbs when...

    With trailer tires you want to inflate them to the max psi listed on the sidewall before driving warms them up. So whatever the ambient temperature is outside basically.

  • Compatibility of Provider ST205/75R15 # TR20515D with Utility Trailer with Load Range C Tires
    Yes. The Taskmaster Provider ST205/75R15 Radial Trailer Tire # TR20515D will give you the increased quality you are looking for. This is because it comes with a better load range/ply rating (load range D/8-ply) compared to your current tires. Additionally, the # TR20515D are the exact size you have currently, so there won't be any issue with your wheels/fenders. Since the Providers are rated at 2,150 lbs at 65 psi, you won't have an issue with weight capacity either.

  • Tires to Replace 7.75x15 Sized Trailer Tires
    From my research your 7.75x15 sized tires are closest to 205/75-15 and 215/75-15 sized tires. We carry size 205/75 R15 tires like # TR20515D. These are load range D and have a maximum capacity of 2,150 pounds at 65 psi. They also have a higher maximum speed rating than many tires at 81 mph. To compare them to your current tires the Taskmasters have an outer diameter of 27.17 inches when inflated and are just under 8 inches wide.

    As long as the tire size is the same I wouldn't be too concerned about making sure you get the exact same brand of tire to replace your current ST205/75D15 tires. If you are using the trailer to travel as opposed to farm work then I do recommend using Radial tires instead of Bias. Radials will run cooler and have a little bit of flex in them to help make the ride a little more smooth. You will also need to make sure that the load range on the replacement tire is the same or greater than...

  • What Causes A Trailer Tire To Wear Unevenly On The Inner Edge
    A common cause for wear on the inside of a tire is a bent axle or exceeding the weight capacity of the axle. As trailer axles are typically cambered, they are designed to straighten themselves out as the load is applied. If your trailer is overloaded, exceeding the maximum weight capacity of your trailer could then cause an uneven tire wear pattern on the inside edge of the tire. The spindles can also become bent as well resulting from curbing the wheels or hitting pot holes. I suggest...
