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"

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

Had a BP horse trailer with outdated and rusted out rims so when I needed new tired I bought these mounted wheel w/ tires. Cost was about the same as I could replace just the tires at a tire shop. Good combo and have held up great over the year they have been in use. I have no reason to believe the tires wont survive 3 yrs in the Central CA heat like any other 703414

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.

Ordered on a Friday afternoon and received it Tuesday afternoon. I thought that was fast. Easy to find, easy to order, and couldn’t beat the price for a tire already mounted on the rim. I needed to replace my bass boat trailer tire, since someone stole my other one off the trailer. I will get my trailer rims/tires from you when they need replacing. 613036

Our high school club crew team needed new tires for our food trailer after suffering a massive blow out on I-95 north near Philadelphia. etrailer provided us with a cost effective solution, and two new tires mounted on the rims showed up within days. Free shipping was a huge plus. Thanks to a straight forward web site I was able to find exactly what I was looking for. 514968

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

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


Tires on my 1984 boat trailer were rotten (looked up the date codes and they were year 2000! 17 years old! Ugh..). I ordered a set of mounted tires and rims from etrailer, unfortunately I got an email a few minutes later informing me that the particular size tire was out of stock. I called up and Seth at etrailer hooked me up with these instead, a little cheaper even. Tires are very nice, rims as well. Mounted up great and ride much better than the old ones. My only "complaint" is that the stickers placed on the wheel (Warning: type stickers) are paper, and really stuck on. PITA to clean off. Why they don't put them on the back side baffles me. I'm sure that's not etrailer but the wheel mfgr. All in all a great experience, as always, with etrailer. 397929

    I pulled up as much info as I could for your 2018 Coleman 262BH and found that it has 15 inch wheels and since you said it has a 5 on 4-1/2 inch bolt pattern that means you either have a 225/77-15 and would need part # AC225R645SMV or you have a 205/75-15 and the part # A15R645SMDV or # LHAW130 would be what you need.

  • Will a 225/75-15 Trailer Tire Fit in Place of a 205/75-15 Trailer Tire
    In order to determine if you can go to a larger tire size you have to look at the available space all around the existing tires. The tire size you have now, 205/75-15, has a diameter of 27.1 inches and a width of 8 inches. The 225/74-15 trailer tire has a diameter of 28.31 inches and a width of 8.78 inches. This means above the tires you would measure up approximately 0.65 inches (a little over 5/8). If there is still space to allow for the travel of the suspension then the height...

If you have a 5 on 4-1/2 inch bolt pattern the best option is the part # AC225R645SMV or if you have a 6 on 5-1/2 inch you'll want the # AC225R6SMQ which is a great option.

If the tow dolly that you have uses a 5 on 4-1/2 bolt pattern then the best tire/wheel combination for your application will be a size 225/75/15 with a Load Range of D.
