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

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"

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


You guys are great. Got the tires/rims out here to Cheyenne in just four days. Also, you guys took a call from me when I saw the dates from a previous order, and thought the tires/rims wouldn't be here in time to haul horses for a bighorn sheep hunt. The date was 2013, but I didn't get that far. Apparently, the order was for a wiring harness I installed on my little roadster (Pontiac Solstice) so I could pull a motorcycle trailer, had been noted on the sheet. Anyway, you straightened me out, the tires came on time, and they are beautiful. Thanks again for working with me on this. The horses will arrive safe west of Cody at the trail head thanks to you. I'll send a picture of the ram when it is harvested. 422914

Ask the Experts about this Taskmaster Trailer Tires and Wheels

  • Benefits of Switching to Trailer Tires with Higher Load Range and Speed Ratings
    Excellent question. There is no disadvantage to using a special trailer tire with a higher weight Load Range Rating than is required by your trailer's weight. Doing so simply means that those higher-rated tires will tend to run cooler, since they will be operated below maximum capacity, and this is always a good thing with any tire. Heat is the worst enemy of a tire and the two conditions that typically lead to excess heat build-up are overloading beyond rated weight capacity and...

  • Load Range E Trailer Tire Size 225/75R15 and Wheel with 5 on 5 inch Bolt Pattern
    Since the bolt pattern 5 on 5 inch isn't super popular we don't have a ton of pre-mounted options for wheels and tires. Best option is like you mentioned mounting the tire # C22515E and wheel part # AM20538DX.

  • Advantages of Wider ST225 Trailer Tire Over ST205 Trailer Tire
    There are a few things to consider when purchasing new tires and wheels for your camper. A wider tire such as the Contender ST225 # AC225R6SMEQ can certainly provide more traction on the road than the factory size tires on your camper, however this might only be noticed in very specific conditions such as off-roading. A wider tire may offer minimal improvement with trailer sway. The best way to fight against trailer sway is to properly load your trailer. You want to keep the tongue...

  • What Rating Should Trailer Tires Have for Camper that Weighs 15,000 Pounds
    When determining the Load Rating of your trailer tires, you will just want to make sure that the load capacity of all of your tires combined exceeds that of your trailer. Trailer tires do have specific load ratings such as B, C, D, E and so on, but the actual weight capacity of specific tires can still vary within the same rating. The actual maximum load at a particular psi will be listed on the tire's product page. If you have 6 tires on your camper, the Contender ST225/75R15 Radial...

  • Why are New Tires on Boat Trailer Showing Excessive Wear
    There are a variety of possible reasons why the new tires on your boat trailer are already showing extensive wear. If by the inside and out, you are referring to the outside edge of the treads and not the side walls, then the most common cause of this are tires that are not properly inflated. You want to make sure the tires on your trailer are always inflated to the maximum psi as listed on the tire's sidewall. If the wear you mentioned is instead on the actual side walls of the tire,...

  • Do the Available Tire and Wheel Combos Come Pre-Mounted
    You are correct. The Contender ST225/75R15 Radial Trailer Tire w/ 15 Inch Silver Mod Wheel # AC225R6SMEQ will arrive already mounted and inflated. Like you mentioned, you will just want to check the air pressure on the tire once you have it mounted to your trailer to ensure it is inflated to the recommended 80 psi. This tire and wheel combo has a 6 on 5-1/2 bolt pattern, a maximum load of 2,830 pounds at 80 psi and a maximum speed of 81 mph.

  • Converting Trailer from Drum Electric Over Hydraulic Brakes to Disc
    I attached a help article that covers adding disc brakes to a trailer for you to check out but basically you are going to need to swap out your hub/rotors and also swap out the drum brake actuator you have with one designed for disc brakes as they require a higher psi. So for a Dacromet coated disc brake kit that is confirmed as a fit for your 5,200 lb axles you'd want the # K2HR526D but you are going to have to also upgrade you wheels and tire to a 15 inch setup since none of the disc...

  • Compatibility of Load Range E Upgrade on Current Wheels of 2008 Sundowner Horse Trailer
    The Provider ST225/75R15 Radial Trailer Tire - Load Range E # TR225LRE you mentioned would be an upgrade from your current tires. The tires are rated for up to 2,830 lbs at 80 psi, but your rims rated for 2,600 lbs will reduce the total weight capacity to 2,600 lbs max at that 80 psi. That combination would provide an extra 60 lbs from each tire but you will also get a higher ply rating, so a stronger tire with a thicker sidewall for more durability. An even better option would be...

  • Recommended 225/75R15 Size Tires with a Load Range of E for a Boat Trailer
    Although we don't have any tires in the 235/75R15 size we do have the 225/75R15 size. If you are only looking for tires then I recommend the Goodyear Endurance # 724857519 which has a load rating E (2,830 lbs at 80 psi) and a speed rating of 87 mph. This is the best tire that we have to offer in this size. For a tire and wheel combo that has a 6 on 5-1/2" bolt pattern I recommend the Contender # AC225R6SMEQ. This has a load rating E (2,830 lbs at 80 psi) and a speed rating of 81 mph....

  • Trailer Axle Replacement for 2015 KZ RV Spree Escape 200 with 65-1/2 Inch Spring Centers
    It does sound like you either have a bent axle since your wheels are pointing inward at the top. It sounds like an overloading issue caused this because with water you stated your weight is well above the max capacity of 3,500 lbs. The axle and springs would be rated for the same capacities so springs and axle need replaced. You can increase the axle capacity, but that doesn't account for the other components like the frame, the coupler, springs, etc. that may also be rated for that...

  • Recommended Replacement Trailer Tires and Wheels for 8.75R16.5
    We do not carry any tires that are 16-1/2 inches to fit the 16-1/2 inch wheels like # 17-163-7. That is more commonly a Light Truck Tire for use on a motorhome and requires Light Truck which we don't carry in that size or Passenger tires which we do not carry at all. If you want to change out both wheels and tires on a trailer, then I do have a recommendation. The 16 inch size is far more popular than the 16.5 inch and will give you many more options but will also give you larger and...
