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.

Had these a year now with no problems. Don't know why anyone would pay more for a trailer tire!

Customer service from John A was great. The tires were great. Bought a set for my other trailer and was extremely good tires

Tires and service was excellent

Haven’t had these tires very long, but they look really good and seem to work well at hwy speed in the rain. These are a great buy for any trailer wether it be a boat, landscape, or just everyday hauling trailer. Thanks

- TTWTR21514

I cannot write a product review as the tires I ordered are still in the box, but I can write on the order experience. I have ordered before from Etrailer and have had excellent experience in the order process, shipping and pricing. Very streamlined and efficient method of ordering. Another item that impressed me was the video that explained in detail everything about the tires I ordered. It answered a lot of questions I had about the tires. The price was the best I could find with the free shipping.

- TTWTR21514

These tires were priced right and did the job. Delivery was prompt with no issues. I would definitely use again.

- TTWTR21514

Could not believe how fast their shipping was! Tires are already installed and are top quality. Just what I needed for long trips pulling my bass boat and trailer. Thanks!!

- TTWTR21514

Receive tires in three days was which was extremely good. great place to do business with, tires look good ,took a lot of weight on one rim to balance ,but the tires are on the trailer now but haven't put them on the highway yet so we'll have to wait and see how they perform

- TTWTR21514

Replaced 4 tires on a boat trailer (3200lbs gross weight) and so far so good no problems .Traveled to Colorado river on first trip in 110 degree weather last summer they handled great on the road. At this time I’ve only put on approximately 3000 miles they look new and have worn evenly.

- TTWTR21514

Customer service was great once again with Etrailer. There were some issues upon order placement of finding the requested quantity of tires. Etrailer reps George and James did a great job of bringing this to my attention and offering other options as well as letting me know the expected lead time to receive the quantity requested of brand requested. Stuck with this as lead time was only a few more weeks and they actually came in after only one week. The communication was very good and much appreciated. Have not actually had a chance to inspect the tires but will follow up with another review upon doing so. Thanks guys! Steve

  • Spare Tire Availability For RV In Size 215/75R14
    The replacement tires in size 215/75R14 that I recommend are the Provider ST215/75R14 Radial Trailer Tire - Load Range C # TTWTR21514 or the # TTWTRTM2157514D which is the same tire in Load Range D.

  • Speed Rating for ST Trailer Tires
    ST on a tire does stand for Special Trailer and is the style of tire you should always use on a trailer wheel. 65 mph is a very common speed rating for an ST tire but here lately we are seeing that number increase. It used to be nearly all were 65 mph rated but now 81 mph is a very common rating too. Especially on the larger sizes. For example, the ST215/75R14 # TTWTR21514 that you referenced has an 81 mph speed rating, but we also have a Goodyear tire in this size part # 724865519 which...

  • Lift Kit for Tandem #12 Dexter Torflex Torsion Axles
    So long as your 2005 Jayco has tandem #12 Dexter Torflex axles that are mounted on the side you can use the Torflex Lift Kit - Tandem Axle # K71-725-02. We don't have any way of knowing what is on your trailer but if you take a quick peek at the axle you should see a sticker on the beam that has the axle number, and if it says #12 and your axles have a 5,500 lb to 7,000 lb capacity each, you can use this kit. If you find you have a different axle you can use one of the following kits: -...

  • Replacement Tires For 215/70-14 On Boat Trailer
    The closest in size tire we have available to the 215/70-14 are the ST215/75R14 tires like part # TTWTR21514 but the diameter is larger then your current tires so I do not recommend using them as a spare tire on your trailer. The current tire size on your trailer part are typically passenger vehicle tires. It is not a good idea to use vehicle passenger tires on trailers because they aren't designed to handle the vertical downward force of a trailer's weight which can lead to blow outs....

  • Should I replace My Castle Rock ST ST205/75R14 Tires
    This type of question is always challenging due to the amount of varying opinions, different experiences, and lack of controlled environment with set standards. Please keep in mind that Castle Rock is an economy trailer tire so they will not perform at the same level of a Goodyear tire. However, feed back available to me was a statement of a 7,500 mile trip with great performance and no significant wear. But your 12,000 mile trip will be pushing the limit on most any economy tire currently...

  • Recommended Replacement ST215/75R14 Boat Trailer Tires
    I recommend going with the Taskmaster Provider ST215/75R14 tire. It comes in both a Load Range D ( 2,200 lbs at 65 psi), part # TTWTRTM2157514D, and a Load Range C (1,870 lbs at 50 psi), part # TTWTR21514, depending on what you already have. One of the most popular features of most Taskmaster tires is the 81 mph speed rating. Since a lot of trailer tires are rated for only 65 mph, these tires will allow you to make better time on the road. Both tires also come with a 2-year limited warranty. I...

This tire is rated for 1,870 lbs at 50 psi and speeds up to 81 mph. This tire has automotive grade sipes to channel water away to improve traction. If you want tires made by the same manufacturer as your Castle Rock tires, I recommend the Westlake ST205/75R14 Radial Trailer Tire - Load Range D # 274-000012 which are rated for speeds up to 75 mph and weights...

  • Do Trailer Tires and Wheels Need to be Balanced
    Trailer tires and wheels do not typically come balanced from the factory like what you see with standard passenger vehicle tires. This isn't usually needed for trailer tires and most car shops don't have the needed setup to properly balance trailer wheels, which are usually lug-centric instead of hub-centric like automotive wheels. Many of our tire and wheel manufacturers line up the light spot on the tire with the heavy spot on the wheel, which is a type of balancing and typically nothing...

  • Can a ST215/75-14 Trailer Tire Replace a G78-14ST
    The modern size equivalent to the G78-14ST that you have is the 205/75-14. The ST215/75-14 size you are interested in is close enough to this size that it would work just fine. I would recommend the Provider ST215/75R14 Radial Trailer Tire - Load Range C # TTWTR21514 as it is a radial tire in the size and Load Range you want plus it has a higher speed rating of 81 mph unlike most trailer tires that are only rated for 65 mph.

  • Is Adding Larger Tires A Good Way To Lift My Forest River Camper with Tandem Axles?
    Adding slightly larger tires than your current ST205x75xR14 might help a little bit; but the Provider ST215/75R14 # TTWTR21514 tires that you were looking at are only going to raise your trailer about 6/10", so I'm not sure those are going to be the best way to go. The other thing that comes into play, in addition to the space between the tandem axles, is the space between your current tires and the bottom of the frame of the trailer. With all that being said, I don't think you're going...

  • What If My Trailer Tires Do Not Have Red or Yellow Dots
    The red and yellow dots are not present on all trailer tires nor do they need to be in order to mount them correctly. The presence of these dots varies by manufacturer. If the tire has just a yellow dot then this indicates the tire's light spot and can then be aligned with the wheel's heavy spot which is the valve stem. If the tire has yellow and red or just a red dot then this indicates the high point for both radial runout and radial force which then can be aligned with the valve stem...

  • Can a Trailer Tire Rated for 65 Miles Per Hour be Run at 70 Miles Per Hour
    Going 5 miles over 65 is not going to damage a tire if you are within the capacity of the tire and it is inflated to the max psi rating on the tire. I still would recommend keeping it at or below the speed rating though to avoid any potential issues down the road. With that said there are some tires that are rated over 65 miles per hour. If you have ST215/75R16 tires I recommend # TTWTRTM2157514D. This is a load range D rated for 2,200 pounds at 65 psi and has a speed rating of 81 miles...

  • Recommended Replacement ST215/75R14 Tire for Single Axle Boat Trailer
    For a replacement ST215/75R14 tire on your single axle bass boat trailer, I recommend the Provider ST215/75R14 Radial Trailer Tire # TTWTR21514. This is a premium radial trailer tire that has a 1,870 pound maximum load at 50 psi. The tire meets DOT specifications, exceeds FMVSS and comes with a 2-year limited warranty. There is no harm at all with going to a load range D tire. Just keep in mind that your trailer's weight capacity will still be limited to its weakest component. For example,...

Therefore, you should not have any clearance issues. However, there are also other factors you need to consider when selecting new trailer tires and those are load range and speed rating.

  • Recommended Replacement Tires for Boat Trailer with P215/70R14 Tires
    Your boat trailer tires should be replaced as the P in front of the number stands for "passenger" meaning they are not intended for trailer use but rather to be used on a car. The ST on the tires you see from us are "special trailer" tires intended for use on trailers only. I've attached an article to assist.

    The correct tire pressure for a trailer tire will be indicated on the tire sidewall. Trailer tires should always be inflated to the full cold psi pressure noted on the tire. They should never be run under- or over-inflated since this can reduce their load capacity and lead to overheating. Tires will vary in their required pressure based on their rated load range.

  • Are Trailer Tires that are 7 Years Old and Inflated to Half Max Pressure Rating Safe to Use
    We don't recommend using trailer tires that are over 6 years old as they are much prone to failure. The tread may look fine but the tire overall is most likely dry rotting and beginning to lose it's integrity. Also, we have to recommend you run the tires at max tire pressure at all times. Failure to do so will cause heat to build up due to too much sidewall flex/heat which will also cause premature failure. Basically running a 6 year old trailer tire at half the max pressure rating is a...

  • Trailer Tire Recommendation for Replacing P215/75-14
    You really need to go with an ST rated tire which we can help you with. The P rated tires are only to be used on passenger vehicles and not on trailers. We have ST215/75-14 tires that would work well for you. For that the best option is the radial Taskmaster # TTWTR21514 which has a weight rating of 1,870-lb max load at 50 psi and a speed rating of 81 mph. Most trailer tires are only rated for 65 mph so the extra speed rating is nice. I attached a review video for this as well.

  • Can 16 Inch x 6 Inch Trailer Wheels be Replaced with 16 Inch x 5-1/2 Inch Trailer Wheels
    There should not be any issues when switching from a 14" diameter x 6" wide wheel to a 14" diameter x 5-1/2" wide wheel on your boat trailer. The wheels do have a weight capacity rating but that does not mean the wider 6" wide wheel will have a higher capacity than a 5-1/2" wide wheel. They both vary right around 2,000 lbs per wheel so you should be just fine. The only thing I recommend when choosing wheels for a boat trailer is that you get ones that are made of aluminum like part # LHSO211B...

  • What Tire Pressure Should Trailer Tires be Inflated to
    Yes, you will always want to have your tire pressure inflated to the max rating that is listed on it's sidewall. ST trailer tires are designed to be run at their max PSI at all times. Failure to do this will reduce the overall capacity of the tire and can cause excess heat build up. I attached a help article on trailer tires for you to check out as well.
