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"

Very happy with these tires. I put them on goose neck horse trailer which was blowing tires left and right. Since I've had these, no blow outs and over 10,000 miles on them. 863181

Tire and rim arrived timely and are all I expected. Purchased as a spare, so I won't be mounting it right away. 810031

Two yrs ago , I bought 6 tires and wheels for my toy hauler to take a 10,000 mile trip ! I went from 225/75R 15" LR D to 235/80R 16" LR E wheels and tires and that has worked out great . At that time I decided to use the smaller wheel and tire for the spare, but now I bought another 235/80R 16 LR E FOR THE SPARE ! The wheel and tire shipped quickly and they are good tires !!!!! 573285

I bought these tires for my 33’ travel trailer. Great price and an excellent tire. 513300

- AC16R6WM

These tires have been good. They have a higher load capacity than our previous trailer tires, so we aren't going through so many tires. Haven't had a flat since we changed over. 6 rims and 6 tires, working great. 481156

Look good on my freshly painted trailer. Quick shipping, just what I needed 476550

I give it 5 stars, the rims and tires were exactly what i needed, quickly. 2 days delivered, heavy duty tire, on heavy duty rim, with air in it. Unbelievable. All for the price of a new tire, downtown, mounted on my own "bent" rim. I have identical rims, American made rims, in close comparison you can see the difference in construction, but im very pleased with the quality of the rims & tires i purchased. My bobcat & I will surely tear the shit out of them and then buy new ones, from etrailer, without hesitation. 441788

It has been a about a year since I purchased these rims and tires. Very pleased with both. The tires are long gone of course. If you gonna stay busy, you gonna use up some tires??. Tires lasted as long as any tire ive been runnin. The rims, still Rollin true, not bent at all, and they take an awful abuse pullin these bobcats. And they still clean-up nice. Thumbs up up??fellas, and...ladies, down at e-trailer. Ps i recently installed a gooseneck hitch on my 2014 2500 RAM i purchased from e-trailer. Its freeakin awesome!

If you pull a 5th wheel or travel trailer, you hear stories of blow outs and tire issues that disrupt your trip and mess up your trailer ! My tri-axle 5th wheel is due for new tires, so I did a lot of research before buying. (etrailer has a lot of good advise) My original tires were 225/75R15 LR D, my new tires are 235/80R16 LR E, I believe by increasing the size that I reduce the heat issue that causes problems. I got my tires and wheels in just 2 days after ordering and at a good price ! I am planning an 8000 mile trip this summer and I will follow up with how the tires do . 363040

Arrived today on time everything in order. Thank You Again for the great service. 353181

Here are some pictures of what the tires are going on. You also can see the tires that I replaced. There are some difference in size and looks. In one picture I took, you can see the tires and axle mounted on the frame. I'll get some better pictures when I pull the trailer out of the garage and wire the tail lights. The new tires and rims are a great looking and should give me a lot of service. Thank you again Etrailer.com for helping me get my order straighten out after I made a mistake and ordered the wrong tires and rims. Shipping was fast too. 332813


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

Seems like a good product. The paint on the inside of the rim was a little light. In 5 years we will see how it holds up. So far everything seems perfect. 931897

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

On my older trailer I couldn't find a replacement interior lamp. But, did purchase clearance and an outdoor light. In addition I purchased a spare tire with rim, hard to find sink repair, and some smaller items. I am very pleased with all these products: price, quality, and service. The proof that I'm pleased with etrailer is that just this week I have made additional purchases. Return customers the crown of a good business. 787193

Ask the Experts about this Taskmaster Trailer Tires and Wheels

  • Can Trailer Tire Size ST225/75-15 Be Replaced with 235/80-16
    The diameter difference between the two sizes you mentioned is 2-1/2 inches. Now since half of that additional diameter is split between the wheel center you would only end up losing 1-3/4 inches of fender clearance. That means you'd go down to about 3-3/4 inches of clearance since you have 5 now. Normally we recommend at least 4 inches of clearance so you're pretty close. For the larger size mounted on a white wheel we have the part # AC16R6WM which has a 6 on 5-1/2 inch bolt pattern....

  • ST235/80R16 Trailer Wheel and Tire Availability for Keystone Outback
    In that tire size you would want the part # AC16R6WM for if you need a 6 lug wheel or the part # AC16R8WMQ for if you have an 8 lug wheel as those are the two common bolt patterns for 16 inch trailer wheels. Both of the tire setups have speed ratings of 81 mph which is higher than most trailer tires so that is why we prefer them. The outer diameter is 30.79 inches which will be right at 2 inches taller than what you have. That means you would gain an inch of additional height. You will...

  • How Many Miles Can Be Expected from ST235/80R16 Tires on a 32 Ft 5th-Wheel
    It's very difficult to put a mileage expectation on trailer tires such as the Contender ST235/80R16 # AC16R6WM. Trailer tires are built with thicker side walls and are designed to carry heavy loads, so they aren't typically rated like vehicle tires. Usually the expected life of a trailer tire will be around 5 or 6 years, depending on use, supported loads, travel speed, etc. I have included a link that takes you to our selection of 235/80R16 tires.

  • Is Contender ST235/80R16 Radial Trailer Tire w/ 16" White Mod Wheel Balanced
    The Contender ST235/80R16 Radial Trailer Tire w/ 16" White Mod Wheel # AC16R6WM isn't balanced on the wheel like you'd find for vehicle tire/wheel combos. This is the case for all of our trailer tire/wheel combos because trailer tires don't really need to be balanced due to how they are used. There is no harm in having them balanced though if you choose to do that once you have received them.

  • Do I Need to Replace Valve Stems When Going From Load Range E to Load Range G Tires?
    While there are tire/wheel combinations available using a 235/80r16 tire, you are able to use the tire only # PRG80235 with your existing wheels instead of the wheel and tire combo. As you mentioned you will need to swap out the valve stems to accommodate the higher pressure rating on your new tires. You'll want to use the Americana Metal Bolt-In Valve Stems # AM20906, which are rated to be used with up to 200psi. Most tires at this size have a weight of around 35-lbs and a total weight...

    While we do not have wheels that are both 17-1/2" AND 6-On-5.5" bolt pattern. I might have some options. If you want 6-5.5 pattern, the largest I can offer is 16" wheels like the West Lake # LHAWSJ511S radial tire with sporty aluminum wheel, or Contender # AC16R6WM radial with steel wheel in 16" If you prefer 17.5" wheels you will have to jump to an 8-On-6.5" lug pattern, as on the Provider # TTWA215H-8H19 radial tire with steel wheel.

A 235/80R16 is 9.3 inches wide and has an outer diameter of 30.8 inches so a bit shorter but a little bit wider. The # PRG80235 is a 235/80R16 that would work well if you have room for the extra width. It has a weight capacity of 4,080 lbs at 110 psi and would fit the wheel you have now.
