Platinum Plus Warranty with Roadside Assistance

This tire-and-wheel assembly comes with a Platinum Plus warranty that includes complimentary roadside assistance for 2 years. If your trailer has a flat tire, call the help line and a technician will come change out the flat tire with your existing inflated spare tire. The service is available 24 hours a day, 7 days a week. In addition to the roadside assistance, this warranty also includes other benefits and services.


Extreme Salt Resistance (ESR) Finish Is Environmentally Friendly

This wheel has an extreme salt resistance (ESR) matte black finish, which is sprayed on over a layer of e-coat primer. Compared to galvanized finishes, this highly corrosion-resistant finish withstands the effects of saltwater and inclement weather for a longer period of time. ESR-finished wheels performed for more than 700 hours in salt spray tests.


In addition, this ESR finish is an eco-friendly alternative to galvanized finishes, which can be bad for the environment.


Improved Torque Retention Technology

Dark Matter Beveled Stud Holes

The automotive-rated center disc is raised and the stud holes are beveled and uncoated for better clamp force retention. This technology helps the wheel stay tight against your hub without the need for constant retightening.


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.


Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.


Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)


Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)


Bolt Pattern - Side

Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Video Transcript for Taskmaster Tires and Wheels - Tire with Wheel - AC225R6DMM Review

Speaker 1: Today we're going take a look at the Contender ST225/75R15 Radial Trailer Tire in a load range D on this 15" modular steel wheel with the 6 on 5-1/2" bolt pattern, and the black ESR finish.Now, this tire and wheel assembly is ideal for boat trailers, stock trailers, utility trailers, and campers. The wheel is a sturdy steel wheel. It has the modular design, and when we say modular design, that's the one that has the round holes all the way around the wheel. This wheel has a ESR finish, which stands for extreme salt resistance. This'll weather the elements better than galvanized finishes. It's a matte black finish that's sprayed on over a e-coat primer.

It gives you excellent corrosion resistance, has a salt spray rating of more than 700 hours, and the finish is also applied through an environmentally friendly technique.The wheel also uses ITR technology, which is improved torque retention. It's designed to help keep your wheel securely in place on your trailer. It uses the uncoated stud holes, which are beveled to give you better clamp force retention.Now, the tire that's on this is a radial tire. It is constructed with double steel belts, double polyester cords. Great for highway use.

They do also use a nylon tread-firming belt overlay to help prevent tread separation, and they even offer the tread depth bars, like you'll see in your passenger car tires. Basically what that is, it's in the tread grooves, and it gives you a quick visual indication of how your tread is wearing.The tire is a special trailer tire design. It'll couple the strength of a bias tire with the durability and stability of a radial tire. It's created specifically for trailers, not intended for use on any other vehicles. This whole assembly does offer a 2-Year Platinum Plus warranty, which does include complimentary roadside assistance.

Basically, if your trailer has a flat tire, you can call their help line. A technician will come change out the flat tire with your existing inflated spare tire. This service is available 24 hours a day, seven days a week. This assembly does meet the DOT, Department of Transportation, specifications, and it does exceed the Federal Motor Vehicle Safety Standards.A few dimensions on this. We'll start with the wheel.

The diameter on this wheel is 15", and that's always measured bead seed to bead seed, so inside to inside will be a 15" diameter. The width on just the wheel is 6" wide. The bolt pattern on this wheel is a 6 on 5-1/2" bolt pattern, and if you ever want to measure that on a wheel like this that's an even number of lugs, it's pretty easy. All you do is pick any one of the holes, and then measure directly across to the hole right across from it. You go center to center. On this, it'll measure 5-1/2", so six lug, 5-1/2" bolt pattern. The wheel does use the wheel lug size of 1/2" by 20. Weight capacity on just the wheel is 2,830 pounds. The pilot hole diameter, that's the large hole here in the center of the wheel, goes over the hub on your trailer, diameter of that opening is 4.25".Now, the tire size, which will be stamped on the side wall, ST for special trailer, 225.75R15. The R means it's a radial design tire. Section width on this is going to be 8.8". Overall diameter from the bottom to the very top is 28.3. This tire is a load range D, so that means it's an 8-ply rated tire. Has a maximum load capacity of 2,540 pounds at 65 p.s.i.The last thing I want to mention is most all your new trailer tires are coming through with speed ratings on them now. A speed rating is always stamped on a tire by a letter designation, and you usually find that . On this one, it'll be . Here's the size of the tire. Right after, you'll see two numbers, which are the load index, and then the letter M. Speed rating M will mean it's an 81 mile per hour speed rating on this tire.But that should do it for the review on the Contender ST225/75R15 Radial Trailer Tire in a load range D on this 15" modular steel wheel with the 6 on 5-1/2" bolt pattern, and the black ESR finish.
