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.

I am very pleased with the Provider ST225/75R15 radial tires purchased from etrailer. They were ordered on 1/7/19 and amazingly delivered on 1/8/19. I just had the bearings repacked and the tires mounted on my 2017 Venture Sonic Lite. The ride is extremely smooth. I am looking forward to getting out on the highway for the first trip of the year! Thanks, etrailer, for selling quality tires at a great price!

Carl P.


Throughout the first year of traveling with the Provider ST22575R15 mounted on my travel trailer, I have been impressed with the performance of the tires in wet or dry road conditions and the lack of tread wear. When the time finally comes to get new tires, I will once again purchase the Providers.


Etrailer sells quality products. Tires were shipped fast, each was individually boxed. Great quality, no concerns. Would buy anything from etrailer with confidence.


great tire fast shipping awesome


Simple, easy, excellent and fast delivery and on time...will use again!


Great service from etrailer as usual.


Shawnee was awesome to work with. She said it and did it perfectly.


I thought the tires were as advertised and had no problem with delivery or
quality. These are used on my sixteen foot utility trailer hauling loads of hay, about
6,000 lbs No problems. Installed them on the wheels myself with my hand tire changer. Worked great..

Thank you,


Ken W.


Tires are still doing great . No problems with heavy hay loads..


Great tires for my dump trailer


Have not mounted the tires yet but the tires arrived on time and were packaged well.




We put 4 taskmaster tires on a tandem trailer and they have been very good. They are of good quality and wear evenly. The white spoke wheels we purchased worked well with the new tires Thanks


Speedy service from etrailer is standard. The tires arrived boxed & in perfect condition.
The super service is more than you can ask for, last year I had a blowout on the road and would be passing buy etrailer on Sunday. I was met at the door with a spare tire.
That's why I buy here.
The tires look good on, but not trailered yet.


I have purchased four of the TTWTRTM2257515D and really like the looks of the tires. The employees are super and I will continue to do business with them. These tires that i purchased replaced cracked tires that was on my RV.


I have purchased several products from Etrailer in the past & found their products and service to be very good. I recently ripped a sidewall on one of my dump trailer tires running over something at our local landfill. I found an EXACT replacement tire at Etrailer for a good price, free shipping, & fast delivery. I expect this tire to perform as well as the original tires that came with my dump trailer (in service 4 years, no problems) as it is an exact match.


Bought because of the previous reviews. Fast shipping of the tires. I just had the tires mounted and balanced but haven't used the 5th wheel yet. Tires look great with a nice tread pattern. Time will tell.


Excellent and fast service best product and speedy delivery best agent ever which is Sherry which really knows her job. Always good job!! thanks


After one year and about 8,000 miles, I've been very happy with these tires on my travel trailer. They have a higher speed and load rating than the Goodyear Marathons that I had before and these seem to ride quite smoothly.


Really glad to get my new set of trailer tires today. As always my order was shipped quickly and accurately. I always appreciate your how to videos. Came in handy when I replaced the wheel bearings.




Trailer Tires appear to be a good product at the right price (etrailer's price pledge was very helpful in keeping me from purchasing from the local big box store). Delivered in a timely fashion allowing me to get the trailer back on the road in no time. Expect these will last a good long time


Like for like replacement tires on my trailer! My current set of tires have been all over the south east and have been a great set. Tire wear is minimal and good traction in all weather conditions. Etrailer provided a reasonable price, easy ordering and super fast shipping! I would definitely buy from them again! I Highly recommend both the tires and Etrailer!


Tire arrived in good order.


NOTE: Be sure to check the tire speed ratings!
was about to order a cheaper tire and happened to notice that it had a lower speed rating. Ordered these for our single Axle Malibu boat trailer and they seem to be working great. Excellent service from etrailer too! Thanks!


Great tires, I tow my trailer a lot and after one year of driving on this tires, they still look almost new. I will buy them again for sure.

I'm very happy with the tires ans also with etrailer for the great customer service.

Angel M.


I received the radial trailer tires I ordered. Impressed with sidewall construction of the 8 ply tires. Hard to compress unmounted . Good sign. Just over $100 apiece and worth every dime.

  • Trailer Tire Recommendation to Replace a ST205/75R15
    I have a better solution for you than the tire you referenced. The part # TTWTRTM2057515C is the exact same size as what you have and is also a radial tire. The # TTWTRTM2257515D would be a bit larger than what you currently have and has the less preferred bia-ply construction. The main difference between a radial ply and a bias ply tire is how the tire is constructed. The cords inside a bias ply tire run at a 32 degree angle to the direction of travel, and the cords on a radial tire...

  • Replacement Tires for Trailer with Size 255/75-15 Passenger Tires
    You are on the right track getting rid of the car tires for trailer tires. Car tires aren't designed for the vertical load that trailer tires are and are more designed for vehicles with a steering axle. The closest tire size we have to what you currently have is 225/75-15 like the part # TTWTRTM2257515D which would be a great option. The difference between the D and R in the tire size is the construction of it. D means bias-ply and R means radial which is the preferred construction. The...

  • If You Upgrade Trailer Tire Load Ranges Should You Increase PSI
    Trailers tires, regardless of load or application will need to be filled to the max psi listed on the sidewall while cold. This is to ensure the correct temperature remains inside the tire as well as the correct wear pattern. If you upgrade tire load ranges then this can sometimes lead to a harsher ride so your first thought is to reduce pressure but this will unfortunately create issues with temperature and wear. This is the reason that you really shouldn't upgrade load ranges unless absolutely...

  • Recommended Trailer Tire Replacement for BR-78-15 Tires
    The BR-78-15 tires are an older tire size designation. Stated in modern terms, the size would be ST225/75-15 so I recommend the Provider ST225/75R15 Radial Trailer Tire - Load Range D # TTWTRTM2257515D. This tire is rated for 2,540 lbs at 65 psi and speeds up to 81 mph. It has automotive grade sipes to help with traction in wet or snowy conditions. The radial tires will work much better than your older tires because they will distribute heat better which will give them a longer lifespan.

  • Could a ST205/75R15 Load Range C be Replaced with a ST215/75R15 Load Range D
    Typically the limiting factor for trailer tire pressure is the valve stem. The Taskmaster Tire part # TTWTRTM2257515D you are interested in has a 65 psi max rating which should be just fine with your rims as long as you go with similarly rated valve stems.

  • Red and Yellow Dots on Trailer Tires Explained
    Typically the yellow dot indicates the point on the tire that SHOULD be mounted next to the valve stem for the best balance. The red dot is the uniformity mark. As well as not being able to manufacture perfectly weighted tires, it's also nearly impossible to make a tire which is perfectly circular. Every tire has a high and a low spot, the difference of which is called radial run out. Manufacturers typically mark this high point with a red dot on the tire sidewall. When you have this...

  • Can a 225/75R15 Tire Replace a 205/75R15 on a Trailer
    Most likely yes, but you will need to consider the addition height of the larger tire size to know for certain if your trailer can accommodate the larger tire. The height difference between the two sized you mentioned is 1.3 inches total. That means you will lose about 5/8 of an inch of fender well clearance since only half of that additional distance will be above the center of the wheel. Chances are you will be fine, but you will want make sure you have at least 3 inches when it is all...

  • Recommended ST225/75R15 Trailer Tires for 10,000 lb Trailer
    Tires are one of the things that are overlooked quite a bit so upgrading to a high-quality set of tires is a really good idea as they will not only help your trailer's suspension stay in good shape but also help ensure safe traveling. So for your 5th wheel trailer with a 10,000 lb GVWR the ST225/75R15 trailer tires I highly recommend are the Provider ST225/75R15 Radial Trailer Tire # TTWTRTM2257515D.

  • What Tire Pressure Should Trailer Tires be Inflated to on Coleman Travel Trailer
    Trailer tires should always be inflated to the maximum cold psi as listed on the tire's sidewall, regardless of the trailer's weight. Under-inflating a trailer tire can potentially lower its capacity and performance. So for the ST225/75R15 tires on your Coleman Travel Trailer, you will want to make sure they are always inflated to the 65 max psi that you mentioned in your question, whether the trailer is completely empty or fully loaded. This psi number falls right in line with the ST225/75R15...

  • Replacement Tires For A Motorcycle Trailer With Wheels P205/70R15
    When it comes to replacing the wheels on your motorcycle trailer with tires (P205/70/R15) I would recommend The Provider ST225/75R15 Radial Trailer Tire # TTWTRTM2257515D. The P205/70/R15 tires that you currently have are for a passenger vehicle and are not ideal since it is not rated for the vertical loads that all trailers have.

  • Replacement Trailer Tire Recommendation for Trailer with P223/75R15
    You should never run a P rated tire on a trailer. Whoever installed those tires on your trailer did so hopefully by mistake as that's not safe at all. A great tire to use as a replacement would be the part # TTWTRTM2257515D which is an ST225/75R15 that would fit and work well. It also has a higher speed rating at 81 mph compared to most trailer tires that are only rated for 65.

  • Can Passenger Vehicle Tires Be Used in Place of 225/75R15 Tires
    We can not ever safely recommend using passenger tires on a trailer. They are not rated for the vertical load that trailers see. If there is any way you can save up till you can afford to use all trailer tires it will be the way to go. In the tire size of 225/75R15 we have the part # TTWTRTM2257515D which is pretty cost effective and would also potentially save you money in the long run in the event of passenger tires failing on your trailer and causing damage!

  • Why Choose Radial Tires Instead of Bias Ply Tires
    For highway driving radials like the item # TTWTRTM2257515D that you referenced are usually preferred because radials have more flex in the sidewalls which gives them excellent traction on paved roads. For off-road driving or driving on rough surfaces a bias ply tire is often preferred because it has stiffer sidewalls that will hold up better to the uneven surfaces. As far as the weight Load Range goes you can always select the appropriate size tire with a higher weight capacity if one...

  • Would a 15 inch Trailer Tire Be Able to Handle 65 PSI
    Your wheel is going to have the capacity to go with higher capacity as most rims themelves have a 200 psi capacity. What you need to be aware of is the PSI capacity for the valve stem as that typically is the limiting factor. That being said when you replace the tires the shop is going to also replace the valve stems as that is standard practice. As long as you tell them that you need something rated higher than 65 psi you would be good. Most likely you are looking at the size 205/75-15...

  • Replacement Tire For 8.25-15 or H-78 15 Trailer Tires
    The suitable replacement for H-78 tires would be the tire size 225/75-15 which is 1.3 inches different in diameter from the 205/75-15 tires. I suppose you could get away with the 205/75-15 to get by in an emergency or temporary situation. However, my recommendation of a tire such as Provider ST225/75R15 Radial Trailer Tire # TTWTRTM2257515D will give you piece of mind. The maximum speed rating is 81 mph (speed rating M).

I recommend changing out all of the tires on your trailer and using a tire like the Taskmaster ST225/75R15 Radial Trailer Tire, part # TTWTRTM2257515D. This is a Load Range D tire that has an 8 ply rating and has a maximum load capacity of 2,540 lbs at 65 psi. Tires that are designed for trailers...

  • Switching From ST205 to ST225 Without Changing Spare Tire
    The difference between those ST225 tires and the ST205 sizes can be around 1 inch in diameter and 1 inch in width depending on the other tire measurement information. It will make your spare the wrong size to use. I'd personally ask them to change out your spare if everything looks and functions well. I've attached an article to assist in the actual measurement differences. You should always use tires of the same size, load range, and construction on a trailer. If you use tires that...

  • What is the Speed Rating for ST225/75R15 Tire with Load Range D
    Most trailer tires do have a maximum speed rating of 65 mph unless otherwise indicated on the tire. I do not recommend exceeding a trailer tire's speed limit because this can lead to excessive heat on the tire, which is the most common cause for failure. The speed rating is not really related to its Load Range but simply specific to the particular model tire you are looking at (not all Load Range D tires have the same speed rating). For example, we do actually have the Provider ST225/75R15...
