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.
Beveled Stud Holes
The stud holes on this steel wheel are beveled to ensure that the wheel stays tight against your trailer hub. This also eliminates the need to constantly retorque the lug nuts.
Standard Trailer 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 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.
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.)
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.)
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"

These were a big improvement to my trailer. Put them on and immediately took a 4K mile trip- ride smooth and silent both fully loaded and empty. Ended up cheaper and easier than trying to find replacements locally. Bought another set 6 months ago for another trailer. Highly recommend! 469365

Very good prompt service and shipping. All items came as ordered in a very timely manner. Purchase was fast and easy online and web site was easy to navigate. Prices were excellent for rim and tire as most all other tires were more without the rim included. I would recommended and will return to purchase other tires and or tire and rim packages when need arises. Thank you 257660

Review from a similar Contender Silver Mod in Trailer Tires and Wheels
I ordered two new tires and new rims for my small utility trailer. The price is right, the quality is good and the customer service is great. The order was acknowledged super fast and the tires and wheels were shipped same day. A link was provided for tracking. The tires were received in 4 days from ship day. They fit perfectly as expected because the site offers a great deal of educational information on how to measure the various critical items to assure you order the right tire and wheel. I am very happy with my purchase from etrailer. Thanks George! 340120

Review from a similar Contender Silver Mod in Trailer Tires and Wheels
I think I got the wrong ones! When I looked on the tires I already have on my boat trailer it says 205/75/D14. What I got from you was 205/75/R14. Will they still work? 549461
Comments
The tire you ordered is a ST20575-14 radial tire in load range C. A load range C tire will have a 1760 lb per tire/ 3520 lb per axle capacity. The old tires you had were the same exact size, but in a slightly higher D load rating. A D-rated tire typically has a 2040 lb per tire/ 4080 lb per axle capacity. So, long story short, it the combined weight of your boat and trailer are less than the sum capacity of the tires 3520 for a single axle or 7040 for a tandem axle youll be perfectly fine.

Ask the Experts about this Taskmaster Trailer Tires and Wheels
- Comparing 4.80R12 vs ST175/80R13 for Boat TrailerAll things being equal it's almost always better to go with a larger trailer tire size when possible. You'll get a smoother ride quality on the trailer and since smaller wheels turn faster at the same speed as larger wheels you end up putting less stress on the hubs and wheels/tires as well. So I'd recommend the part # AC13R45SMQ which will work great. The only thing that might make a slight difference to push you towards the part # AT12R45WM instead would is that since this is a boat...
view full answer... - Replacement Trailer Tire for ST 175/80/13The # AC13R45SMQ is the same size as your ST175/80/13 that you're currently using; the C91/87L notation at the end simply refers to the load range, maximum air pressure and speed rating. The # AC13R45SMQ is a Load Range C tire, with a capacity of 1360-lbs, so it's capacity will be similar; however it is only an M rated tire for speed which limits it to 81mph. If you'r trailer has 5 on 4-1/2" hubs, then this tire would be a good replacement for you to have as a spare tire. If you've got...

view full answer... - Will the Tire and Wheel Combos Come BalancedThe Taskmaster Contender ST175/80R13 Trailer Tire w/ Wheel, # AC13R45SMQ, are not machined balanced. What some manufacturers will do is line up the light spot on the tire with the heavy spot on the wheel. This is a type of balancing but not like how car tires are balanced. You may have the wheel/tire professionally balanced if you wish, but having perfectly balanced tires is not as important with trailer tires as it is with a passenger vehicle.

The Karrier ST175/80R13 Radial Trailer Tire w/ 13" Galvanized Wheel # AM31952 is definitely the better was to go for your application. It utilizes the same tire, but the wheel has a galvanized finish which does a much better job at resisting harsh chemicals like salt than...

view full answer... - Replacement Wheels/Tires for a 2005 Fleetwood Resolute Popup CamperI have the solution for your wheel and tires on your trailer. For your application, I recommend using a radial tire over the bias ply tire. Radial as designed for the speed and heat generated during highway travel. Radial tires will flex more than a bias tire, giving radials better traction and stability. Radial tires tend to run cooler than bias tires. Heat is then main cause of tire failure on trailer tires. Therefore, the cooler running radial tires will last longer. I recommend...

Since these are the same for the Contender w/ 13" Silver Mod Wheel # AC13R45SMQ (aside from the pilot hole being bigger). This wheel fits on 1/2"-20 studs. It is usually good to check the stud size as well which I encourage you to try measuring the studs themselves as all of our 13" wheels are compatible with 1/2" diameter...
