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"

Review from a similar Contender White Spoke in Trailer Tires and Wheels


This is the third or fourth set of wheels/tires I have purchased from etrailer.com along with other items. They are so great to deal with. I ordered these late Thursday and they arrived noon on Monday - wow ! etrailer is straight forward. They told me the wheel/tire assemblies are roughly balanced. They place the heavy tire spot opposite the heavy wheel spot. So if you want a perfectly balanced set you should go to your nearest tire shop. Worth the effort since the etrailer prices are so good. The tire shop said they were only slightly out of balance. I went up a size from R14 to R15 and fatter profile 215 to 225. added almost 700 pounds of extra safety margin, meaning the tires are lightly loaded. obvious to the eye. Thanks etrailer. I do not like operating tires near capacity! Follow the standard recommendation: Change your trailer tires at 12,000 miles even though they look new. 564538


Comments
Because trailer tires dont have a steer or drive axle, its nowhere near as crucial for a trailer tire to be perfectly balanced as it would be for a passenger vehicle tire. Regardless of the milage theyve seen, its a good idea to consider replacing trailer tires around the 5 year mark as continued exposure to UV radiation from sunlight is harmful to the compounds used in the manufacture of tires.

Installed these on a 1996 Jayco 30' Travel Trailer. The tires look great and perform well. It originally cam with Steel Belt Radials but I change to Bias. They did not perform well and only kept on for a short time before going back to these. They ride well and wouldn't know the trailer is behind. Well pleased!! 439009

  • Recommended Tire and Wheel to Upgrade Size on Utility Trailer
    The Contender ST175/80R13 Radial Trailer Tire w/ 13 Inch White Spoke Wheel # AC13R45WSQ should work well for replacing the smaller 4.80X12, 5 on 4-1/2 inch tire and wheel currently on your trailer. This tire has a ply rating of 6 and a 1,360 pound max load at 50 psi. I definitely recommend measuring the space between the trailer axle and top of wheel well to ensure you will have adequate space for larger tires. You will want to have around 4 inches between the tire tread and the underside...

  • Are Special Trailer Tires/Wheels Sold by etrailer Fully Balanced
    The wheel/tire products we sell come from the distributor already mounted together. These wheel/tire items are not dynamically balanced on machinery the way a passenger vehicle tire is because trailer tires do not need to be as well balanced as vehicle tires do. You certainly could have your trailer tires dynamically balanced but it is not necessary. When our suppliers join a tire and wheel they do match up the high spot on the tire to the low spot on the wheel. This provides a degree...

  • 13 Inch Trailer Tire and Wheel that Can Use Baby Moon Hubcaps
    Baby moon hubcaps such as # AM90086 are designed to fit what are called conventional steel wheels but will not fit spoke wheels like the one with tire and wheel combo # AC13R45WSQ. Tire and wheel combo # AM31241 has a conventional steel wheel but it has a -1/2 inch offset meaning that the wheel mounting surface is not in the center of the wheel. It is 1/2 inch further away from the trailer which moves the tire 1/2 inch closer to the trailer. If you have the space for it then this tire...

  • Recommended ST175/80R-13 High Speed Trailer Tire & White Spoke Wheel for Boat Trailer
    Radial trailer tires offer advantages over bias ply types in certain situations. For primarily highway driving, especially if this will be at speeds over 65-mph, a radial special trailer tire is the way to go. For off-road use a bias ply tire's stiffer sidewall often provides better load support than a radial. Your current B78-13 tires have a load rating of 1360-lbs at their 50-psi pressure which equates to a modern metric tire size of ST175/80-13 in Load Range C. The radial special...

  • Selecting Spare Wheel/Tire for 2017 Keystone passport 2400BH
    When selecting a spare wheel/tire for your trailer you need to match up the tire size and load range, both of which are indicated on the tires' sidewalls, and the wheel size and bolt pattern. A wheel that measures 14 x 5-1/2 can accept two tire sizes, 205/75-14 and 215/75-14, but you'll naturally want to match what is on the trailer. You also need to match the wheel bolt pattern to ensure the new one will fit on your hubs. The two linked articles will help. The linked page displays 14-inch...

  • Replacement PWC Trailer Tires for Size 4.80-12
    Since the wheels are in good shape I would recommend just replacing the tires with a pair of the part # TT48012C which will work great. These radials have more than enough weight capacity and a higher speed rating and would give you the simplest way to get your trailer back on the road. The advantages of going to a larger wheel and tire are mainly higher weight capacity which you wouldn't need so I wouldn't think it would be a worth your money to go that way. Also worth noting is that...

  • Availability of 13 inch Trailer Wheels for 2009 Aliner Scout
    We have quite a few 13 inch wheels for trailers. If you check out the link I attached you can see them all. We have wheels individually and we also have wheels with tires mounted. The most common bolt pattern is the 5 on 4-1/2 inch like what the part # T134SMN5 has. If you need a tire too I would recommend the part # AC13R45WSQ as the tire that comes on it is a radial which is preferred.

  • Smallest Wheel and Tire Setup to Fit 10 inch Brake Hub on Trailer
    13 inch trailer wheels are the smallest you can go to fit over a 10 inch hub and drum. The smallest tire size to fit that rim would be a 175/80-13 so for that size on a wheel that would bolt up to your trailer you would want the # AC13R45WSQ. Overall diameter is 24.02 inches.

    The Timbren Axle-Less Suspension Systems are great for both off and on road use. You can certainly use them on the highway.

    When choosing tires, it is important to choose a tire that matches, or exceeds, your axle's capacity. It is also important to note that trailer tires should always be inflated to their maximum psi. The max psi will be noted on the tire's sidewall. If you need a tire with load range B, I recommend the Loadstar Bias Trailer Tire # AM1ST74. This tire has a max load of 1,100 pounds at 35 psi. You will want to double check your bolt pattern, but if you need a tire and wheel with 5 on 4-1/2...

  • Can I Use an Undersized Trailer Tire for Emergency Purposes
    I recommend always keeping all of your trailer tires the same size. Not doing so can be dangerous even while driving short distances. As long as the smaller tire fits with your trailer's hub and spindle it will work in an emergency to get to the nearest stopping point, but I would not advise driving longer distances. I instead recommend staying with a matching size 175/80-13 tire. For a tire of this size with a 4 on 4 inch bolt pattern you can use Loadstar # AM3S030. For a 5 on 4-1/2...
