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.

Second tire I have ordered and I can't be happier with the products! I have place multiple orders in the past including many different items and have never been disappointed yet. Job well done guys! I'm from Canada and will be trying to get you more customers from up here. Your pricing and shipping process is flawless! 498662

I go through brakes and tires every year. These tires are used on a 16ft dump trailer carrying 10000 lbs payload constantly. No problems. Good job e trailer! Price, shipping and customer service cant be beat!

I have about 1500 miles on these. Had them installed and balanced. They show zero wear. The first trip was from El Paso the Phoenix in July. 120 degrees at 70 mph tires did great. 516621

Tire and rim arrived timely and are all I expected. Purchased as a spare, so I won't be mounting it right away. 815874

I have been building custom trailers for years and have purchased everything from axles to gooseneck receivers from etrailer. Great prices for top of the line accessories and super fast shipping. I won't go anywhere else. 583660

- C23516E

Looks to be overall well made, but I am not real impressed with the tread. I’m not sure it will wear well. Since this is to be a spare though, I will keep it. Also the tire was already 1 year and 9 months old when I received it. 519793

The product is exactly what I needed for a replacement tire for my dump trailer. $10 for mounting at the local repair shop and the tire looks great. Price was a little bit better than I could get locally and delivery was exactly when etrailer said it would be. I have pretty much resolved to purchase all of my trailer (I have 9) products through etrailer. It has always been as good of a price as I can find locally, and they deliver right to the door, most of the time for free. Easy Peasy. 477192

  • Will Inflating ST235/80R16 to Maximum PSI Cause Tire to Overheat
    That is a good question but inflating a ST235/80R16 trailer tire such as the Contender # C23516E or Westlake # LHWL401 to their max psi, which is 80 for both tires, will not cause it to overheat. Trailer tire manufacturers have tested the psi and rated it to so that inflating it to the max psi takes into account the build-up of heat, and these are also radial tires, which flex more and run cooler than bias tires, which is another reason for their rated psi. You want to inflate these...

  • Recommended Replacement Tires 235/80R16 For 5th Wheel Trailer
    For your replacement tires, I recommend the Taskmaster Contender ST235/80R16 Radial Trailer Tire - Load Range E # C23516E. These tires are rated for 3,520 lbs at 80 psi and have a speed rating of up to 81 mph. These are really nice tires at a great price point. Since you are traveling cross-country, you may want to consider the Westlake ST235/80R16 Radial Trailer Tire - Load Range E # LHWL401 with a weight rating of 3520 lbs at 80 psi and a speed rating of up to 75 mph.

  • Replacement Tire Needed for 9.5-16.5 Size Tire
    The 235/80-16 sizes tires are the closest size that we have to your 9.5-16.5 tires. Your current tires should have a diameter of 30.6" and the 235/80-16 tires measure 30.9" in diameter. When it comes to clearance with your trailer you will actually be reducing that by only 0.15" since diameter is from one end of the tire directly across to the other side of the tire. If this works out for you then I recommend going with the Taskmaster Contender Radial Trailer Tire # C23516E which has...

  • Recommended PSI Level For ST235/80r16 Carlisle Trailer Tires
    When I researched Carlisle trailer tires ST235/80r16, the maximum PSI is 80. But read the following recommendations before filling to this PSI. To find the recommended PSI for your Ez-Loader trailer, there maybe a plate on the trailer frame near the coupler. There should be the PSI, VIN, axle capacities, as well as the trailer tire size and Load Range recommended. Also the owners manual may list the PSI as well.

  • Recommended Tires for M101 Trailer Conversion to Camper
    I don't recommend using the Toyota Tundra wheels on your trailer. Trailer tires and wheels are made differently than passenger vehicle wheels. Passenger wheels normally have an offset so the wheels sit farther under the vehicle where as trailer wheels have a zero offset. Passenger tires are also more flexible in the sidewall to account for turning and a softer ride, where trailer tires have an especially firm sidewall to help the trailer ride as intended. I appreciate your desire to...

  • Radial Tires or Bias Tires for Fifth Wheel Trailer?
    Radial tires are going to be a better option for your fifth wheel trailer. They will flex more than bias tires which means more traction, stability and better overall tread wear; this also means the tires should last longer. Bias tires have a stiffer sidewall and are generally better for use in off-road applications. I recommend moving to a radial tire, and the 235/80-16 Contender # C23516E would be a great option. These tires are rated for 81 mph and have a load range of E, or 3,520...

  • Should Trailer Tire Pressure Always be at Max PSI
    Trailer tires don't generally have ranges which tell you the capacity at different air pressures, which is one of the reasons it is recommended to keep them at max psi; so we do recommend always being at max pressure. For example, the Contender ST235/80R16 Radial Trailer Tire - Load Range E # C23516E has a 3,520 lbs capacity at 80 psi, but no way to know the capacity at 65 psi, let's say. Not inflating it enough could lead to a blowout at worst or uneven tire wear at best. Only the...

  • How Do I Find Out The Max Heat And Max Air Pressure Of A Trailer Tire?
    The max heat of your Duro DS2100 size ST235/80R16 will not be listed anywhere, but the max psi will be listed on the tire. Trailer tires should always be run at that max psi. The heat of your tire, although not rated, will be based on the load and the speed you travel. The load capacity and speed rating is listed on the tire normally with a letter rating of J-62 mph, L-75 mph, or M-81 mph and load capacity of C,D, E, etc. If there is not a speed rating printed on the tire, this will...

  • Do Trailer Tires Need to Have Max Pressure Inflated at All Times
    With trailer tires like your ST235/80R16 you have to inflate the tire to the max pressure listed when the tire is cold to ensure you get the full weight capacity for the tire as well as prevent heat build up. I attached a help article on trailer tires for you to check out as well.

  • Should all Trailer Tires be the Same Size?
    If your trailer specifies to use a load range E tire, you should use one. A load range D tire will not be able to handle the capacity of a load range E tire, so you may encounter your tires wearing unevenly; I recommend the Taskmaster # C23516E, which is a 235/80R16 tire with a load range E. It has gotten fantastic reviews from our customers who have used it and will work great for you. I've added a link to a video review of this product for you to take a look at as well.

  • What is the Difference Between Taskmaster Provider and Contender Trailer Tires
    There is a quality difference between the Taskmaster Provider tire # TTWTRTM2358016E and the Taskmaster Contender, # C23516E. The biggest difference is in the tread. The Provider just has better tread. The Contender was meant as a less expensive radial alternative to a bias ply tire. If it were me I would go with the Provider # TTWTRTM2358016E because of the higher quality and tread difference. I have also included a link to a video review of the Provider as well as a link to our help...

  • Can Load Range E 235/80R16 Trailer Tires Upgrade to Load Range E
    Yes, you can absolutely upgrade your load range E ST235/80R16 radial trailer tires like the Contender # C23516E to load range G tires and they will fit the same 16" rims. The best option is the Provider ST235/80R16 Radial Trailer Tire - Load Range G # PRG80235 which is the same size but has a larger, 4,080 lb capacity when filled to its maximum 110 psi. These tires fit 16" x 6", 16" x 6-1/2", and 16" x 7" rims. I have added a link to a video review of these tires for you to check out....
