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.


Corrosion-Resistant Finish

The steel wheel goes through a 3-step finishing process that makes it both attractive and corrosion resistant. The wheel is first submerged in a zinc phosphate bath to ensure good paint adhesion. It is then e-coated with an acrylic primer base and the outboard side is finished with baked-on DuPont powder paint. The light e-coat on the inboard side of the wheel reduces friction between the wheel and your hub and eliminates the flaking that can occur with a heavily applied paint finish.


Improved Torque Retention Technology

Beveled Stud Holes Front and Back

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"

We had a flat recently while hauling a horse and being very cautious, we ordered this for a second spare for a 2 horse trailer. I like the fact that the wheel matches exactly the existing wheels, the tire is the same rating and it was less expensive to have delivered from etrailer than buying one locally! Great selection and service! 458935

Purchased as a spare for my cargo trailer. Looks good, but made both wheel and tire made in China -- guess that is about what is available these days.. Have not had it on the road, so can't comment on that. Fantastic help from Sam at etrailer when ordering, and absolutely the best service with almost immediate shipping . What we all expect from them, and they did not disappoint. 308104

  • Difference Between Taskmaster Wheel and Tire ST225/75R15 and Kenda ST225/75R15
  • The wheel and tire combos you mentioned are both similar in size and appearance as they are both Load Range D ST225/75R15 size tires mounted on a white wheel with 6 on 5-1/2 inch bolt pattern. The biggest difference is the speed rating of the tire. The part # AC225R6WM has a tire with a speed rating of 81 mph so it would be what I recommend. The Karrier is only rated for 65 mph.

  • ST Rated Tire Recommendation to Replace P235/75R15 on Trailer
  • P series tires should NOT ever be used on a trailer. They are not rated for the vertical load that trailers like your fifth wheel will see. You need to replace your tires with ST rated tires. The closest ST tire size is the ST225/75R15. Which for a wheel and tire in that size with a 6 lug pattern you would want the part # AC225R6WM for a spare. For just the tires of this setup you would want the part # C22515D.
