Standard Trailer Tire Tread

Contender Tire Tread

The standard tread on these tires has solid, continuous ribs, and it has very few sipes (or thin grooves) cut into the rubber. These tires are designed for use on trailers, so they don't require the level of traction that would be needed on a vehicle that is braking or steering.


Contender radials have double polyester cords and double steel belts. A protective layer of nylon is wrapped around the steel belts to help prevent tread separation.


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.

Video Transcript for Review of Taskmaster Tires and Wheels - Tire Only - C22515E

Today we're going to take a look at the Contender ST225/75R15 Radial Trailer Tire in a Load Range E. Now, this is a radial ply tire. It's great for highway use. Constructed with double steel belts, double polyester cords and it does use a nylon tread firming belt overlay around the tire to help prevent tread separation. Does offer the tread depth bars, like you'll see in your passenger car tires that give you a quick visual indication of how your tread is wearing. And this tire is an ST tire which stands for special trailer tire, has the sturdy sidewalls so that it can handle heavy loads and it's created specifically for trailers.

It's not intended for use on any other vehicles. This tire will meet the DOT, Department of Transportation, specifications and exceeds the Federal Motor Vehicle Safety Standards.This tire is designed to fit on a wheel size of 15" by 6" wide, 15" by 6.5" wide, or 15" by 7" wide wheels. The tire size, which is stamped on the sidewall, it's going to be ST for special trailer 225/75R15. The R designates that it is a radial design tire. Section width on this tire is 8.8".

Overall diameter from the bottom to the top when it's inflated is 28.3, and this is a Load Range E, which means it's a 10-ply rated tire. So it does have a maximum load capacity if it's used as a single tire on the axle as being 2,830 pounds at 80 psi. inaudible 00:01:28 chooses a dual tire on each side of the axle would be 2,470 pounds at 80 psi.And the last thing I do want to mention is most all the new trailer tires are coming through with a speed rating stamped on them now. And the way you can tell what the speed rating is, it'll put a letter designation on the side of the tire. So let's see what we can find that.

It's usually right by the sides. Yes. So right after the size, it'll have speed rating M, which means 81 mile per hour speed rating. But that should do it for the review on the Contender ST225/75R15 radial trailer tire in a Load Range E.

I ordered tires for my RV using the Website, the tires were not available from the distribution centre at that time, Ricky ( e-Trailer Rep) called and gave me some options in a timely manner. Got the tires in my garage a week later than the original delivery date, I liked that they were individually boxed. Great job and thanks for being on top of my order. Exactly what I ordered - no issues. 549827

Tires were an excellent replacement from my original tires - no comparison. My trailer is 10,500 lbs and the wear rate looks good so far.

I blew a tire on my 5th wheel trailer coming home last fall. These were recommended to me as a replacement but they only had two available at the time. Once back on the highway I noticed right away the trailer handled much better and smother. Come spring I could not find these tires available locally without paying an arm and leg for them. I found these on line and purchased another pair. I look forward to be on the road again and seeing what four will do in handling. Service was great through etrailer and will recommend them in the future 666004

Ask the Experts about this Taskmaster Trailer Tires and Wheels

  • How to Select Correct Replacement Tires for Horse Trailer
    There are 2 things you need to look at when choosing a replacement tire. The first is your old trailer tire size (can be found on the tire sidewall), and the second is the weight capacity of your horse trailer. For the example, the Contender Radial Trailer Tire # C22515E that you referenced has a size ST225/75R15 and a load range E which is 2,830 lbs at 80 psi. This means that when this tire is mounted on a axle you count the weight capacity twice so you'd have 5,660 lbs of weight capacity....

  • Is Contender Trailer Tire ST225/75-15 A Good Tire Option for 1976 Shasta Camper
    The Contender ST225/75R15 Radial Trailer Tire # C22515E is a great trailer tire that I would recommend highly for your 1976 camper as long as this is the correct size you'd need. Assuming it's correct size replacement it's a really great tire all around. It has a higher speed rating at 81 mph, is a radial which means it'll be more stable and run cooler and also has a 2 year warranty.

  • Trailer Tire that Fits 15 inch x 8 inch Wheel
    There is not an optimum E-rated trailer tire size, you will need to choose tires that fit your rim and that have the correct load rating for your trailer. For example you mentioned you had a 15" x 8" rim so option for a tire that has a load rating of E that fits a rim of that size you will need the Contender ST225/75R15 Radial Trailer Tire # C22515E. This tire fits 15" diameter rims and has a maximum load capacity of 2,830 lbs at 80 psi; the load capacity is per tire. When inflated...

This tire is weight rated as Load Range E (equivalent to a 10-ply rating) and speed rated as M, meaning good to 81-mph, which makes it ideal for highway use. Correct cold inflation pressure for this tire is 80-psi.

  • Do I Need to Balance the Tires on My Livestock Trailer
    Because trailer tires like the Contender ST225/75R15 Radial Tire # C22515E are designed more with carrying a vertical load in mind, as opposed to gripping the road through turns as an automobile tire would, dynamic balancing of your trailer tires isn't a huge concern. Steering and cornering are of much less concern with a trailer than they are with an automobile. With that being said, you can have your trailer tires balanced if you desire.

  • Best High Capacity Trailer Tire for Size ST225/75-15
    I have a really great and overkill trailer tire I can recommend for your boat trailer that weighs a total of 7,300 lbs with the USA made Goodyear part # 724857519. This has the highest capacity in the Load Range E with 2,830 max load at 80 psi for this tire size, has the best automotive style tread pattern which gives maximum traction in wet and dry conditions and also comes with a really great warranty as well. I attached a review video for this tire for you to check out as well.

  • How to Choose Correct Tires for Carrying a 9,200 lb Formula 33 Boat
    To determine the correct rating you just need to look at the load capacity of the tire. For example, the Endurance ST225/75R15 Radial Trailer Tire # 724857519 has a load range E which is 2,830 lbs at 80 psi. Since you have a triple axle trailer you simply need to multiply the weight capacity by 6 to get the combined weight rating and then make sure it meets or exceeds the GVWR (Gross Vehicle Weight Rating) of your trailer. For this tire the combined weight rating is 16,980 lbs for the singles...

  • Do Contender Radial Trailer Tires Have Good Braking Ability
    The Contender ST225/75R15 Radial Trailer Tire - Load Range E # C22515E have excellent ability to brake due to their deep tread, which is 8.4/32" deep, which is considerable for a trailer tire. So long as you have a good brake controller with proportional braking like the Curt Echo # C51180 you'll have a long-lasting, quality tire. I've added a link to a video review of the tire for you to check out as well.

  • Trailer Tire Load Ranges, Speed Ratings and Sizes to Avoid Blowouts
    Special trailer tires in any given size are available in various load ranges as you noted, but they also can have different speed ratings too. Driving a tire faster than its rated speed can lead to failure just like overloading it past its weight capacity can. Both conditions lead to excess heat and that is what typically leads to a tire failure. Since your 18K trailer has 3 axles and 6 tires each tire should be rated for approximately 3000-lbs if you routinely operate the trailer at...

    I do have options for you but I can tell you now that your car trailer is not rated for anywhere near 15,000 lbs or 16,000 lbs so I highly recommend adjusting your load or purchasing a different trailer. The highest rated 7.00x15 trailer tire we offer is the Kenda Light Truck Tire K391M part # AM10414 which will give you a maximum weight capacity 9,612 lbs (2,403 x 4).

However, the next closest metric tire we have is going to be a 225/75-15 which is going to be 1" smaller in diameter and 1.2" larger in width.

  • Can Different Load Range Tires Be Used Together On a 5th Wheel Trailer
    The tires on a trailer must all have the same load range rating as each load range requires a different psi rating. If you were to fill them all to the same psi then the weight capacity of said tire would be compromised. Therefore, you are going to need to choose a new tires that matches the load range of all other tires on the trailer. If you were to go against this then you would be at risk of a blowout due to increased heat buildup. If you can let me know what size tires you have...

The ST225/75R15 tires are only about a 1" wider and taller compared to the ST205/75R15. The general rule is you want to keep 3 inches of vertical clearance above the top of the tire to allow for normal travel of the trailer's suspension and 1-2 inches of clearance between the tire's sidewall and the closest part of the trailer.

  • Needed Tires for 11500 lb Tandem Axle Travel trailer
    The easiest way to determine this would be to look for the ID plate, which is usually found on the trailer tongue or inside one of the storage cabinet doors. If you can't find that information, we can do a little deductive reasoning and figure out what the minimum size would be. I'll begin by assuming that the 11,500 lb figure you provided is the GVWR or maximum loaded weight of the trailer. For a travel trailer, we'll deduct 10 percent of that for tongue weight and divide the result...
