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.

Ask the Experts about this Taskmaster Trailer Tires and Wheels

  • How to Select Properly Rated Trailer Tires
    Tires only need to have a capacity that, when combined, equal or surpass the GVWR of your trailer, including your 1994 StarCraft Stardust trailer. For example, if you had 13 inch wheels and your trailer had a GVWR of 2,500 lbs you could use the Contender ST175/80R13 Radial Trailer Tire # C17513C which have a 1,360 lb capacity when inflated to their max 50 psi. Two of these tires inflated to max psi would give you a 2,720 lb capacity, exceeding the GVWR of the trailer. So as long...

  • Tire Replacement Recommendation for 1995 ShorelandR with ST175/80-13 Tire
    The best tire recommendation I can make for your tire size that I believe you meant to type of ST175/80-13 would be the part # C17513C. This is a Load Range C radial tire that has a 1,360 lb capacity at 50 PSI. But what really makes this tire great is that it is rated for up to 81 mph whereas most trailer tires are only rated for 65 mph. Your old tires are bias ply tires which radials are the better setup for trailer tires. They run cooler and offer more flex in the sidewall for better...

  • Replacement B78-13ST Tires for a 2011 Little Guy Five Wide Camper
    A 175/80-13 is the modern metric equivalent of a B78-13ST trailer tire. For this, I recommend using the Contender ST175/80R13 Radial Trailer Tire part # C17513C which as the name states has a radial ply construction therefore it will be better for use on the highway. This particular tire also has a load range c (1,360 lb) and outstanding 81 mph speed rating. I really like the Taskmaster brand as they continually offer quality trailer tires to the market which are backed by a two year warranty.

    I couldn't tell you what, if anything, Harbor Freight has in the way of replacement parts for your trailer. But a wheel is a wheel and a tire is a tire. As long as both are the right size you can use any that fit. We have a lot of tire and wheel combos with ST175/80-13 tires with the 5 on 4-1/2 bolt pattern.

  • How To Fix Tire Clearance Issues When Using 185/80-13 Tires
    The recommended clearance for a trailer tire is at minimum 4" from the top to the bottom of the fender. The 185/80-13 tires you have now measure 24.4" diameter x 7.2" wide. The 175/80-13 tires you are wanting measure 24" diameter x 7" wide. Therefore, you will gain about a 1/2" of clearance. For this, I recommend the Contender ST175/80R13 Radial Trailer Tire part # C17513C which is a radial ply therefore will run cooler on the highway and last longer. This is the smallest size without going...

For a 175/80-13 I recommend the Contender ST175/80R13 Radial Trailer Tire part # C17513C and for a 185/80-13 I recommend the Kenda Karrier ST185/80R13 Radial Trailer Tire part # AM10208. The 175/80-13 tire measures 24" diameter x 6.9" wide and the 185/80-13 tire measures 24.7" diameter x 7.2" wide. In order to confirm fit you'll need to measure and ensure you have at least 3" of clearance from the top of the tire...

  • Can I Lower The Pressure On My Log Splitter Tires To Help Smooth the Ride Out
    I know this is not what you want to hear but we must recommend that you inflate the trailer tires to the max psi listed on the sidewall. I will say that plenty of others will lower the pressure in their trailer tires based on the load at the time and they do not have any issues in doing so but that still does not mean we can recommend this. The lower pressure rating of the tire will then allow for a smoother ride but you also run the risk of tire temperatures increasing and then causing...

  • Can 205/75-14 and 175/80-13 Trailer Tires be Replaced with 4.80 or 5.30 Tires
    You may be able to use a 5.30x12 tire size on the boat trailer that is currently using the 175/80-13 tires but you will have to also replace the wheels. The other problem is capacity. The 5.30x12 at most is rated for 1,250 pounds whereas the 175/80-13 go up to as much as 1,610 pounds. The 5.30x12 are also 2 inches shorter and more narrow. The best solution is to stick to the proper tire sizes for the trailers so you don't have to change wheel sizes, which is an extra expense, and so...

  • Troubleshooting Trailer Tire Size 175/80-13 with Center of Tire Wear
    Typically center tire wear is caused by over-inflation or a tire that's just too round due to design or the trailer not being loaded enough for the tire to flatten out. Bias-ply tires like yours won't wear as well as a radial so for a better tire setup you'd want to go to a radial. For your tire size of 175/80-13 the best option would be the Contender part # C17513C which is a radial tire in your current size and is a Load Range C.

  • Trailer Tire Close to Size 5.6x13
    Are you sure you don't have the size 6.5x13 as that is the common old style of tire that's not technically still made. The closest match to the 6.5-13 tires is going to be a 175/80-13. This size has a section width of 7 inches and overall diameter of 24.1 inches. They will fit on 13 x 4-1/2 inch, 13 x 5 inch and 13 x 5-1/2 inch wheels. For that we have the Contender part # C17513C which is a great radial tire with plenty of capacity and a higher speed rating at a great price.

  • ST175/80R13 Trailer Tire Recommendation for 2003 Rockwood Premier
    The difference between the D and the R is that R indicates radial and D indicates bias ply construction. The main difference between a radial ply and a bias ply tire is how the tire is constructed. The cords inside a bias ply tire run at a 32 degree angle to the direction of travel, and the cords on a radial tire run at a 90 degree angle to the direction of travel, or across the tire from wheel lip to wheel lip. A radial tire flexes more than a bias tire, giving it better ground contact,...

  • 13 Inch Trailer Tire Recommendation for Landscaping Trailer
    You would need to go with a trailer tire that has ST before the size as they are the only tires rated for use on a trailer. You would need to go down to a 12 inch tire and wheel so that you can go with something that will fit your trailer. For that you would want the part # AM31208 for if you have a 4 lug bolt pattern or part # AM31206HWTB for if you have a 5. These wheels overall diameter will be just a tiny bit smaller than the size you currently have that does fit.

  • Upgrading from 12 Inch Bias Ply Tires to 12 Inch Radial Ply Tires On Pop-Up Camper
    It is possible to increase the size of the tires on a trailer if you have the additional clearance needed to do so. The benefit of going with a larger size is generally a higher speed rating, greater weight capacity, and a better selection of tires to choose from especially radial ply options. In regards to cons, there aren't many aside form the decreased clearance. Although we don't offer pre-mounted options in the size you need with a radial ply, it doesn't cost much to get them mounted...

  • Trailer Tires Rated to Drive at Highway Speeds
    You are correct about the speed ratings, though it is often recommended not to drive faster than 65 mph because higher speeds will cause heat to build up in the tire and cause a failure. With increased speed comes an increased chance of a blowout. The item you referenced, # AM31957, is a wheel and tire combination. It uses a Kenda ST175/80R13 tire with a speed rating of M, or 81 mph. It is for 13" diameter x 4-1/2" wide wheels with a 5 on 4-1/2 bolt pattern. If you were interested...

  • Recommendation Replacement Tire for ST155/80-R13
    A 5.30 X 12C tire is going to be your best replacement. If you need the 4 on 4 inch bolt pattern # TTWAS53012WS4HP is a good option, or # TTWAS53012WS45HP for the 5 on 4-1/2 inch bolt pattern. These both have the wheel and tire included, which you'll need, since you will be decreasing the size of your rim. The reason I suggest going with the 12 inch rims is because smallest 13 inch tires available, such as # C17513C, are 175/80R13 which is quite a bit larger. Your current tires are...

    When you change trailer tires of any given size to ones with a higher weight load range, say from a C-rated 175/80-13 tire like # C17513C to a D load range one like # AM10210, the tire itself will be able to handle more weight but this does not necessarily mean the entire trailer can.

    Since the only tire that we have that fits a 12 inch wheel and is rated for up to 81 mph is a bias tire, part # TTWSF48012C, I recommend going with a tire that fits a 13 inch wheel. There is nothing wrong with a bias tire; it's just that radial tires will run cooler on the highway than bias tires will. The 3 tires that we have which fit a 13 inch wheel and are rated for at least 70 mph are the Provider # TTWTRTM1758013C, Contender # C17513C, and the Westlake # LHWL101. Both the Provider...
