Bias Tires vs. Radial Tires

Bias vs. radial tire graphic

Bias ply tires are designed for off-road or agricultural applications. They are built with thick, durable nylon cords that are positioned at a 30- to 45-degree angle to the direction of travel. The layers alternate in a crisscross pattern, making the sidewalls stiffer so that the entire tire is able to flex easily. As a result, the tire provides a smooth ride and improved handling when trailering on uneven surfaces.

  • What to Consider When Storing Trailer for Long Period of Time
    Typically it's the tires of a utility trailer that get problematic if stored for long periods of times. Although there are not exact rules for how to store a trailer tire. Our experience shows that the most beneficial way to store a trailer tire over the winter or multiple month periods of non-use involves taking the tires off the trailer and storing them stacked in a cool and dry dark environment. You will also want to let out some of the air using this method. The other option would...

  • Boat Trailer Tire Replacement Recommendation for H78-13
    The closest modern size to what you mentioned is the size 185/80-13 like the Kenda part # AM1ST79 which would fit and work well on your rim. I attached a review video for this tire for you to check out as well.

  • Larger Trailer Tire to Replace Size 175/80 R13 Load Range C
    Yes, assuming you have the clearance between the tire tread and underside of the fender. You'll want at least 3 to 4 inches to allow for the trailer to go over bumps in the road. However, if you plan to keep the 13 inch rim there isn't much taller you can go. The 185/80D13 sized tire # AM1ST79 is only about 0.3 inches larger in diameter compared to what you have now. If you increase the rim to a 14 inch the # AM32161 is a 205/75R14 that would increase the total diameter by a little...

  • How to Choose Correct Replacement Tires for a 2001 Coleman Bayside Pop-up Camper
    The price of tires has risen over the last decade, but that is the case with almost everything. The best way to choose the correct replacement tires is by the tire size listed on your current tires or on the trailer's identification plate. If you can tell me the tire size or send me the picture of the tire information on your trailer, I would be happy to give you a few recommendations. I did some research on your camper, but I have found different tire size information, so it would be...

  • What Is The Highest Load Rating Available For 185/80-13 Tires?
    Hello Barb, thanks for getting in touch. We do offer the 185/80-13 tires but the highest load range available is a load range D. For that I recommend the Karrier ST185/80R13 Radial Trailer Tire - Load Range D # KE68KV. These are D range so 8 ply rated for 1,709 lb max load at 65 PSI. These will be your best option for upgrading from your current C range tires.

  • Highest Capacity 13 inch Trailer Tire Recommendation
    If the total weight of your pop up camper is 3,300 lbs then you would need a wheel/tire combo that at least has the capacity of 1,650 lbs. The closest tire we have to that capacity in your size is the part # AM10210 which has a 1,610 lbs at 65 psi capacity. Your best option would be to bump up to the slightly taller tire size of 185/80-13 like part # AM1ST79 which has a 1,725 lbs at 65 psi. This tire fits the same rim size as your current size and is not even 1/2 an inch taller in diameter.

  • Replacement Tire Recommendation for an ST185/80R13 Size Tire on a Travel Trailer
    The load range D on the Loadstar ST185/80D13 # AM1ST79 actually gives you a higher weight rating than the C load range. For this size D is 1,710 lbs at 65 psi while C is 1,480 lbs at 50 psi. It doesn't hurt to have a tire that is rated for more weight and the benefit to this tire is that it has a max speed rating of 81 mph. If you need a wheel as well then I recommend part # AM3S331 as this is the same tire but it comes with a white wheel that has a 5 on 4-1/2" bolt pattern. Bias tires,...

  • 13 Inch Trailer Wheels with Positive Offset
    There are 13 inch wheels with a positive offset, the Dexstar Conventional Steel Wheel with Offset # AM20212 (White) or # AM20214 (Black). These are 13" x 4-1/2" wheels that have a +0.5" offset; they have a 5 on 4-1/2" bolt pattern so you would need to ensure you have that same bolt pattern. If you are not sure what your bolt pattern is you can take a look at the linked help article which explains how to determine what bolt pattern you have. These wheels are made in the USA and have a 2-year...

  • Can I Switch from ST185/80D13 to the ST205/75R14 on a 2009 Jayco 17C Ex-Port
    It is always recommended that you use the original tire and wheel size that came on your camper but I have calculated the size differences between the two tires. Your current wheel/tire combination, ST185/80D13, has an approximate width of 7.28 inches and is 24.66 inches in diameter. The ST205/75R/14 has an approximate width of 8.07 inches and is 26.11 inches in diameter. The variance in the dimensions are very minimal so you should not have any difficultly making the switch. Just a quick...

  • What Makes Trailer Tires Wear on the Inside Only and Can 175/80-13 be Replaced With 185/80-13
    There are a couple of things that can lead to the tires wearing on the inside only. Basically what is happening is the top of the tire is leaning in towards the trailer causing most of the weight to ride on the inside. This pretty much means the axle is bent, especially if both sides have the same problem. If it were just one side, there is a chance that is just the spindle that is bent. It will keep wearing on the inside until the issue is resolved and that could mean a new axle. You...

  • Replacement Tire Recommendations for a Jayco Trailer
    I would recommend you get Loadstar ST185/80D13 Bias Trailer Tires # AM1ST79. These tires have a capacity of 1,725 lbs at 65 psi and are the same size that you have on your trailer. With trailer tires you will always want to have them inflated to the maximum psi for the best ride performance and tire wear. I attached an FAQ on trailer tires for you to check out also. Karrier ST175/80R13 Radial Trailer Tire # AM10210 that you referenced could also work for you, but it has a slightly lower...

  • Higher Capacity Wheel and Tire Recommendation for Trailer Size 185/80R13
    In the tire size of 185/80-13 the highest Load Range we have is D like the part # AM1ST79 which has a capacity of 1,710 lbs when inflated to 65 psi. The only way to significantly increase your tire capacity will be to go to a 14 inch wheel and tire combo like the 205/75-14 with something like the # AM32161 which has a 2,200 lbs capacity. Tires can fail for a few reasons. Overloading like you mentioned is common. Underinflation is another big one. Tires have to be inflated to their max...

  • Highest Weight Capacity Trailer Tire that Fits 13 inch Wheel
    The highest ply rating tire we have for a 13 inch wheel is 8 and is the Loadstar Tire ST185/80D13 part # AM1ST79 which has a weight capacity of 1,710 lbs at 65 psi. More important than ply rating is making sure the tire has enough weight capacity for the trailer it will be installed on. If this tire has enough capacity then you'd be good to use it. Also worth mentioning is that this tire has a speed rating of 81 mph.

  • 1998 Haulmark 24 Snowmobile trailer - Tires and Axles
    You can confirm your axle capacity by pulling one of your hubs and looking at the reference numbers on the side of the bearing cages. A 3500 lb axle typically has an L68149 inner/L44649 outer bearing. Torsion axles do indeed wear over time which is almost certainly what's happened in your case. As you mentioned 3-4 inches is what you typically want to see as far as fender/ wheel well clearance goes. At this juncture changing the tire size to a 185/80-13 will only provide you a bit above...

  • Largest Trailer Rim Available with 4 Bolt Pattern
    Nothing we offer in the 15 inch rim size comes with a 4 bolt pattern. The largest diameter rim we have that will fit a 4 bolt pattern is a 13 inch rim like the # AM20224 that is a silver rim. The largest tire size would then be a 185/80-13 that would fit it like part # AM1ST79.

  • Should Radial or Bias Tires be Used for a 3500lb GVWR Pop Up Camper Trailer
    I can clear this up for you really quick. Radial tires run cooler and track better than bias ply tires. Bias ply tires are typically a little more heavy duty and better for rough terrain. But you can use either one provided that the size and capacity is enough for the trailer. It is usually best to stick with the tires recommended by the trailer manufacturer. In this case it would be a bias ply tire. For just a tire in an ST185/80-13 we have # AM1ST79 which is rated for 1,725 pounds at...

  • Radial ST175/80R13 Trailer Tires are Not Rated High Enough for a 3,500 Pound Trailer
    The bias ply tires and radial tires in size 175/80-13 in a load range D are going to have the same capacity: 1,610 pounds at 65 psi. The radial is # AM10210 and the bias is # AM1ST77. You will want to match or exceed the trailer capacity and I do not recommend using the tires if you will be over their capacity, even for short distances. The solution is to go up to a 185/80-13 tire load range D. This size is going to be only 0.3 inches taller than the 175s and will also be 0.394 inches...

  • Can Bias Trailer Tires Be Replaced with Radial Trailer Tires
    Yes, as long as the actual tire size is the same, a radial ply tire like the Kenda ST185/80R13 # AM10208 will fit onto the wheel just the same as the bias alternative # AM1ST79 it's replacing. Radial trailer tires differ from bias models due to the 90 degree angle the cords run to the direction of travel (compared to a 32 degree angle on bias). This allows radials to flex a bit more for better ground contact and stability. The physical fit onto an existing wheel and trailer suspension...

  • Largest 4 on 4 Wheels and Tires to Fit a 1972 Hunter Compact Trailer
    The largest diameter wheel we carry with a 4 on 4 bolt pattern is a 13 inch wheel. The largest tire for a 13 inch wheel is an ST185/80-13 tire, part # AM1ST79, which you can then put on a 13 by 4-1/2 inch wheel, part # AM20242. It has an outer diameter of 24.4 inches and is 7.2 inches wide. The only catch here is this is a bias tire, which might be great if you'll be towing on rough roads a lot of the time. If you're primarily going to be on highways I recommend going with a radial tire...

  • Any Issues Going from a ST175D13 Bias Tire to a ST185D13 Radial for 19Ft Boat Trailer
    If your original tires size was ST175/80-13, like # AM1ST79, the new tire will only be 5/8 on an inch taller and 13/32 on an inch wider. As long as you have the clearance, the height of the new tire will not be an issue. As for the difference between a radial and bias tire, I recommend a radial tire especially if you are doing a lot of highway towing. Bias tire do have a stiffer sidewall over many radial tires, but the issue with bias tires is they cannot dissipate the heat like radial...

  • How to Select Replacement Trailer Tires/Wheels for Jayco Pop-Up Camper Trailer
    To select new trailer tires/wheels for your Jayco pop-up camper you'll want to confirm the trailer's axle rating so you can select wheels and tires that have the necessary weight capacity. Usually there will be a sticker or plate on the axle itself that indicates its weight rating. You also want to match up your wheel bolt pattern to make sure new wheels fit your hubs. Most Jayco pop-ups use a 5-on-4-1/2 bolt pattern, but you can refer to the linked article to help you confirm which you...

  • Can 13 inch Trailer Wheels/Tires Travel 65 MPH on Highway
    13 inch trailer wheel/tires like the size 185/80-13 like part # AM1ST79 are rated for up to 81 MPH. Most trailer tires are only rated for 65, so if 65 is the limit you have then you'd be good.
