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...

  • 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...

  • 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.

  • 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.

  • Replacing 175/80R14 Trailer Tires
    I can certainly point you in the right direction. A 175/80-R14 is fairly uncommon these days, but we do have options for replacing them. A 175/80-R14 has a diameter of 25" and is about 6.9" wide. The best replacement we can offer will be the Loadstar ST185/80D13 Bias trailer tire # AM3S331. This has a diameter of 24.4" and is 7.2" wide. So you will be losing .6" of diameter and adding .3" of width. I imagine this will fit very nicely in the current fender area, and you will stay very close...

  • Availability of Load Star ST175/80-13 Radial Trailer Tire on a White Painted Wheel
    I took a look at your order history, and the last tire purchase I saw was a 185/80-13 bias-ply load range D tire purchased back in 2010. This is part # AM1ST79, and was purchased as a tire only, not a wheel/tire combo. For a 175/80-13 radial tire load range C on a white painted wheel, we offer the Karrier Loadstar # AM31951 which is an 8 spoke white trailer wheel with a 5 lug on 4-1/2 inch bolt pattern. For the same tire on a white painted modular wheel with the same wheel bolt pattern,...

  • Why Should Trailer Tires be Inflated to Their Max Pressure Rating
    You will want to inflate the tires to the max psi that the tires have. Trailer tires always need to be inflated to their max pressure to ensure you get their full capacity. Also if they aren't fully inflated the tire can have heat build up which will also cause premature failure. I attached a link below that has more trailer tire info for you to check out as well.

  • Can Trailer Tires Rated for a Combined 3450 Pounds be Used on a 3500 Pound Trailer
    You are very close to the capacity but I would still try to stay under the lowest rated component in the system which in this case would be the tires. If you are always at 3500 pounds, the max capacity of the axle, then I would go with a higher capacity tire. Trailer tires should always be inflated to the maximum psi as indicated on the tire for longest life and to reach their maximum weight capacity. What this means is that you would have to go to a 14 inch tire and wheel. If this is...

  • 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...

  • 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...

  • Will a Larger Trailer Tire Provide a More Stable Ride Quality
    Going with a larger trailer tire will somewhat increase the stability of the tent trailer. Going from a 175 to a 185 series tire wouldn't be that huge of a difference but a larger diameter tire will ride a bit smoother down the highway than a smaller one. Since the size difference is so small you shouldn't have a problem with fender clearance either. If you have a 13 inch wheel you would want the part # AM1ST79 for a 185/80-13 trailer tire.

  • 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...

  • Best Trailer Tire for Rockwood Camper with Tire Size 185/80-13
    If your 2016 Rockwood Aframe camper A192HW has a tire size of 185/80-13 then the best tire we have as a replacement would be the Kenda part # AM10208 which is the size you need but it's a radial and the one you referenced is a bias ply. 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...

  • Will There Be a Difference In Handling Between a Bias and Radial Tire
    There isn't a difference in handling between bias and radial trailer tires; bias tires are designed more for hauling heavier loads and won't flex as much on the side walls. The downside is they'll run a bit hotter than radial tires that are designed for long highway trips where heat can build up. For a smaller camper you really could go either way and won't experience a lack of handling. You can go with the # AM1ST79 which are a bias tire, or the # LHCK105 which are a radial tire. Both...

  • 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...

  • Choosing Between Radial and Bias-Ply Tires for Coleman Bayside Pop-Up Camper
    When the option is available, I always recommend going with a radial tire versus a bias-ply. The ride quality will be noticeably smoother and more stable. Radial tires do a better job shedding heat, and since excessive heat is the number one reason for tire failure, you'll typically get more life out of a radial tire. We offer a ST185/80/D13 tire in bias-ply only, that part # is AM1ST79. We offer the ST175/80/D13 in either radial, part # AM10210 or bias-ply, part # AM1ST77. Although either...

  • Should Trailer Tires Be Inflated to Their Max Psi Rating When Cold
    Trailer tires are designed to be inflated to their max psi when they are cold and can handle the increased pressure that comes when they heat up from driving. The only real way they will get too hot and fail is if you exceed the speed rating for the tire. Special trailer tires are usually rated to operate at a maximum speed of 65 mph. If you exceed 65 mph, heat could build up in the tire and cause it to break down and fail. If a tire is rated to run at a higher speed, this information...

  • Availability of ST175/80R13 Load Range C Radial Tire on 13-Inch 5-on-4-1/2 Silver Mod Wheel
    The Westlake tire/wheel combination you referenced, part # LHAW165, consists of a ST175/80R13 tire on a 5-on-4-1/2 Silver Mod Wheel. While a ST185/80R13 tire will also fit on this same rim, we do not happen to offer this particular combination. The manufacturer offers the most popular combinations of wheel and tire as a pre-mounted item but not every combination is available. You can order a wheel and tire separately if you like and have the tire mounted by a local tire shop. The only...

  • Recommended Method for Cargo Trailer Storage to Prevent Flat Spotting
    When using jack stands like the 2-Ton Jack Stands part # PTW41021 I recommend using one under each of the springs where the axle sits. If the springs are above the axle place them under the axle where the springs are. I also recommend using two on each side of the tongue to eliminate twisting that can occur on your jack weakening the jack mounting location. As another option that can save you a ton of work with jacks and jack stands we offer the Race Ramps FlatStoppers for Vehicle Storage...

  • Difference Between Galvanized and Aluminum Wheel
    We have Loadstar 185/80-13 bias tires and wheels, and they are essentially the same weight; the difference is that the galvanized wheel # AM3S334 is steel with an 8-spoke design and is made to resist corrosion. Galvanized wheels are often the type of wheel that people with a boat trailer might use. The Aluminum Hi-Spec Series S5 Trailer Wheel has a split spoke pattern # AM22323HWT and is clear coated on both sides. This would need to be mounted with the Loadstar ST185/80D13 Bias Trailer...

  • Picking Out Replacement Trailer Tire in Size ST185/80R13
    Hey Aubrey, the Kenda tire part # AM10208 is definitely the way to go. This is a radial tire whereas other option is a bias ply. Radials wear better, and handle better as well as build up less heat so that's definitely the way to go.

  • Is a C Range 205/75-14 Tire Less Likely to Fail than a D Range 185/80-13
    When comparing the 175/80-13 and the 185/80-13 tires, load range D, there is not much difference. The larger 185 is going to be about 0.3 inches taller, about 3/8 of an inch wider, and have a higher capacity at 1,725 pounds at 65 psi. Both sizes will fit on the same rim. Please note the higher capacity does not allow you to carry more weight. Trailer tires should also always be inflated to the maximum psi rating indicated on the tire. The next size up would be a 205/75-14. This of course...
