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.

  • 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...

  • What is the Correct Cold Tire Pressure for a ST215/75R14 Trailer Tire
    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. For example, the linked page will show you radial tires in the ST215/75R14 size you referenced. The D-range tire # TTWTRTM2157514D...

  • Can Trailer Tires Have Different Load Ranges If They Are the Same Size
    You are going to want to have the same tires with an equal load range on both sides of your trailer, even if they are the same size. The reason for this is the different pressures that each tire has means the tires will not wear evenly and this will likely cause problems not only with how the trailer rides but also excessive heat on one of the tires. For example, the Provider ST215/75R14 Radial Trailer Tire - Load Range C # TTWTR21514 has a 1,870 lb capacity at 50 psi while the Provider...

  • What is the Difference Between ST205/75-14 and ST215/75-14 Size Tires
    The main difference between a ST205/75-14 size tire like the Contender # AC14R45SM and a ST215/75-14 size tire like the Taskmaster Provider Item # TTWTR21514 is that the larger number is a slightly larger size. The 205 has a section width of 7.99" and an outer diameter that measures 26.14" while the 215 has a section width of 8.5" and an outer diameter of 27". Each tire size has a variety of load ranges. Although there isn't a "set" weight capacity of a load range, you can find the load...

  • Will Switching From Radial To Bias Ply Tires Help With Trailer Bounce?
    Hey Darryl, thanks for getting in touch. Generally, radial tires are better for reducing trailer bounce than bias ply tires. Radial tires tend to flex a bit more and should not bounce as much as a bias ply. That said, if your tires are excessively worn and starting to separate, this can contribute to the trailer bounce. I do not believe that switching to bias tires will give any significant benefit though. There are most likely other factors contributing to this. Usually trailer bounce...

  • Comparing Kenda Karrier, Taskmaster and Provider Special Trailer Tires in Size ST21575R14
    The three radial special trailer (ST) tires we offer in size 215/75-14 can be seen on the linked page. These include the Taskmaster # TTWTRTM2157514D in Load range D, the Provider # TTWTR21514 in Load Range C and the Kenda Karrier # AM10229 also in Load Range C. All of these radial special trailer tires will provide more flex for better ground contact than a bias ply tire. The main difference between these tires, apart from their load range ratings, is their speed rating. Trailer tires...

  • ST215/75R14 Tire and Black Wheel Recommendations for a Boat Trailer
    For a tire I recommend the Taskmaster Provider ST215/75R14 Radial Trailer Tire - Load Range C # TTWTR21514. This Load Range C gives us the weight rating of 1,870 lbs at 50 psi and we have an impressive max speed rating of 81 mph.

  • 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. For replacement wheel and tire combos in the same tire size, you can look into Kenda ST205/75D14 Bias Tire w/ 14" Steel White Spoke Wheel - 5 on 4-1/2 - LR C # AM3S455 for Load Range C or look into Karrier ST205/75R14 Radial Trailer Tire w/ 14" White Spoke Wheel - 5 on 4-1/2 - Load Range D...

  • Spare Tire for 2024 Coleman Lantern LT 17r
    You will want to use the same tire size for a spare on your 2024 Coleman Lantern. If the appearance doesn't matter to you then you could use the Karrier ST215/75R14 Radial Trailer Tire with 14" White Wheel # AM32181. After looking at pictures I believe you have a silver mod wheel on there right now. If you want the spare to look the same you could get the Dexstar Steel Mini Mod Trailer Wheel # AM20363 and the # TTWTR21514. We do not have a wheel and tire combo in this style.

  • Difference Between D and R 215/75-14 Tire Sizes
    The D stands for "Bias" while the R stands for "Radial". Bias tires have a stronger sidewall and are usually used for off-road applications like agricultural trailers (although they can be used for highway-type trailers) while Radial tires have a little more flex in the sidewalls which helps keep them cooler at higher speeds so they are more ideal for highway usage. It's always a good idea to use the same ply-type on the trailer since their sidewalls have different amounts of flex as you've...

  • 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. I attached a review video for this tire as well as a help article...

  • 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,...

    Thank you for the photo of the wheels on your boat trailer! The photo helped me determine that a match for the existing wheels are no longer avaialable. Instead, I recommend a comparable wheel, the Aluminum Jaguar Trailer Wheel - 14" x 5-1/2" Rim - 5 on 4-1/2 - Gunmetal Gray # LHSJ211G.

  • What is the Speed Rating for Karrier ST215/75R14 Radial Trailer Tire # AM10229
    Karrier ST215/75R14 Radial Trailer Tire # AM10229 is rated for 65 miles per hour. If you want a tire in the same size and load range that has a higher speed rating then I recommend Provider tire # TTWTR21514. It has a speed rating of 81 miles per hour. I have included a link to a video of this tire for you.

  • 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...

  • 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....

  • 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...

  • 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. For your 14 inch wheels, I recommend the Taskmaster ST205/75R14 Radial Trailer Tire - Load Range C # TR20514 which is rated for 1,760 lbs at 50 psi and max speeds of 81 mph. This...

  • Replacement Trailer Tire Size ST215/75R14 Recommendation
    Going with a higher rated trailer tire than needed doesn't really offer any real advantages so if you are good with the Load Range C you have now I would stay with it. I would recommend the Taskmaster part # TTWTR21514 this is a radial in the same size and Load Range as what you have, but what really sets it apart for me is the speed rating. Most trailer tires are only rated for 65 MPH but this one is rated for 81 MPH. This tire has a capacity of 1,870-lb max load at 50 psi. If you do...

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...

  • 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.

  • Switching From 215/75-14 to 205/75-14 Trailer Tires
    The 215/75-14 tires that you have now are 26.7" diameter x 8.5" wide and the 205/75-14 tires that you are inquiring about are 26.1" diameter x 8.1" wide. 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. The type of tire must also be noted as only special trailer (ST) and some light truck (LT) tires are rated for use on trailers The best 215/75-14 tire...

  • 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...

  • What Does a Pin Plate do For Wheel Balancing Process
    I found the question you referenced where Adam mentions a pin plate adapter. Basically it's a way to make sure the wheel is perfectly mounted before it's balanced to ensure you get the best balance possible. In a trailer wheel scenario it's probably a bit overkill but most tire shops have them.
