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.

  • Tire Recommendation for a Trailer Used on Paved and Dirt Roads Size 175/80-13
    The best tire for your trailer will really depend on how much time you spend on paved roads versus dirt or gravel roads. At the 175/80-13 tire size, you can choose between a radial tire and a bias ply tire. Radial tires, like part # AM10210, have more flex, better ground contact, traction, tread wear and runs cooler than a bias ply tire. A bias ply tire, like part # AM1ST77 has a thicker sidewall and is ideal for off-road use, but if you spend more time traveling on paved roads, a radial...

  • What is the Difference Between Load Range C and D ST175/80D13 Trailer Tires
    The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like # AM1ST77, the capacity is 1,610 pounds at 65 psi. For a C load range in the same size, like # AM1ST76 , the capacity is 1,360 pounds at 50 psi. Adding the D load range tires of the same size will fit your trailer, but they will not allow you...

  • What is the Difference Between ST175/80D13 and ST185/80D13 Tires and Load Range C and D
    The ST185/80D13 trailer tire will be 10mm wider and the tire will go from 24 inches tall to 24-1/2 inches tall. Just make sure you have space to accommodate the extra height and width so that you do not end up with tire rub. Load range C tires have a ply rating of 6, and load range D tires have a ply rating of 8. Load range D tires are bit heavier built and have a higher weight capacity. The ST175/80D13 tire you were looking at is load range D and can bear 1,610 pounds at 65 psi. An ST17580D13...

  • How to Determine the Right Air Pressure to Fill a Trailer Tire
    I can end this debate for you real fast! Trailer tires, which will have an ST in front of the size, should always be inflated to the maximum psi indicated on the tire. Trailer tires usually do not have a recommended and maximum psi indication so I am curious if the tries on the camper are ST tires or regular passenger vehicle tires. On a regular trailer tire you would inflate it to the max psi indicated on the tire because trailer tires are built with a thicker sidewall to handle more vertical...

  • Can I Reduce The PSI On My Load Range G Trailer Tires?
    Hello Mike, thanks for reaching out. We do not recommend that you lower the PSI on your tires. Trailer tires should always be inflated to the maximum PSI listed on the sidewall. The load capacity of the tire is dependent on them being inflated properly. Lowing the PSI lowers the capacity to an unknown rating. This can potentially lead to overloading the tires.

  • Replacement Trailer Tire 175/80R13
    We have a great replacement tire that is 175/80R13, part # AM10210. It is not a white wall tire though, and we don't carry any white wall tires. But this tire is a radial tire that would work great on your camper. Check out the review video I attached for this tire as well as the help article I attached on trailer tires.

  • Recommended Tire for Camper With 7,700 lb GVWR
    A radial tire is actually a better option than a bias tire; radial tires are going to flex more than bias tires and also run cooler, which means they are better for standard driving. A bias tire is going to be better for off-road, agricultural use so I highly recommend a radial tire for a camper. In terms of your load range C tire with a rating of 1,820 lbs, that would mean when inflated to the max 50 psi the tires have a capacity of 7,280 lbs and you will want a capacity that is at least...

  • Should trailer Tires Be Inflated To The Max PSI When Cold?
    Hello there Cathy, I can definitely help clear this up. Trailer tires should always be run at the listed max psi and filled to that psi while cold. By cold I mean when it is not being used on the road. So, filling a tire to the max PSI on a hot Florida day is still considered "cold" in tire terms. The 80 psi for cold is just for the tire being cold and wouldn't be the max psi once it actually heats up. You are right that the PSI does increase when you start driving. Generally, it is 1...

  • Can Trailer Tires be put on Horse Drawn Wagon?
    It is feasible to put trailer tires on your horse drawn wagon. You would need to get tires that fit the same size wheel, which is 13 inches, and also make sure that your new tires have the appropriate load range for your wagon. We have tires that will fit 13" wheels and are sized 175/80-13. Your current tires are 7.3" wide and have a diameter of 23.2"; tires that are 175/80-13 are 6.9" wide and have a diameter of 24". The option for a load range D radial tire, which has a maximum capacity...

  • Is The Tires The Same ST205/75D15 And ST185/80D13?
    Hello Joe. The ST205/75D15 and ST185/80D13 are not the same at all. The typical ST205/75D15 tire like part # AM32424 is 8.1" wide, 27.3" in diameter and will fit 15" wheel. The typical ST185/80D13 like part # KE33JR is 7.2" wide, 24.6" in diameter and will fit a 13" wheel. So, not only do they require different wheel sizes, but the actual dimensions of the tire are also quite different. The max weight ratings are different too. The only similarity is they are made by the same brand...

  • 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...

  • Will ST175/80D13 Tire and Acorn Lug Nuts Fit Aluminum AM03 Series Gunmetal Gray Trailer Wheel
    Hi Mark; the Aluminum AM03 Series Gunmetal Gray Machined Trailer Wheel # AM73NR uses acorn style lug nuts with a 60° cone like the # 12CLN. An ST175/80D13 tire like the # AM1ST77 will fit a 13" x 4-1/2" rim.

  • Can a ST175/80D13 Size Tire Fit on a Aluminum Hi-Spec Series 06 Trailer Wheel # AM20281B
    Yes, the tire size you mentioned ST175/80D13 will fit on the Aluminum Hi-Spec Series 06 Trailer Wheel # AM20281B. This is a 13 inch diameter wheel that is 5 inches wide and the tire size you have will fit 4-1/2 to 5-1/2 inch wide wheels. For a tire in the size you mentioned you would want the part # AM1ST77.

  • What is Difference Between Trailer Tire Load Ranges
    Trailer tire Load Range is a way to organize tires by weight capacity. The higher the Load Range the higher the weight capacity will be. The actual capacities varies by tire size though so it's hard to be more specific than that unless you had a tire size in mind. For example the # AM1ST77 that you referenced is a Load Range D and has a capacity of 1,610 lbs at 65 psi. This is the highest Load Range option we have in this tire size of ST175/80R13 but a Load Range C in this size has capacity...

  • Advantage of Replacing Trailer Tires with a Different Load Capacity
    The advantage of changing from a Load Range C tire like # TTWTRTM1758013C to a Load Range D tire like # AM1ST77 is the weight capacity. It won't increase the capacity of your trailer, like you mentioned but you also don't want to decrease your capacity because your tires aren't rated high enough. Your trailer's capacity will be limited by its lowest rated component.

  • 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...

  • How to Determine If you Have Clearance to Go from 13 in Wheels to 14 in Wheels on a Travel Trailer
    That really depends on your suspension setup and how much travel the suspension has. Basically if you go to a 14 inch wheel there will be about 1 inch less room between the tire and the fender well and at most an increase in width of 45 millimeters. Without knowing more about your setup the best advice I can give you would be to measure what clearances you currently have with the info I just said in mind and determine if you think you have enough clearance. Going to a larger wheel will...

  • Why Use Trailer Tires with a Higher Weight Rating
    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 # TTWTRTM1758013C 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. A trailer's gross vehicle weight rating (GVWR), which is the most it can ever weigh when loaded, is a function of all the parts in the trailer, including the coupler, frame, springs, axle, hubs, wheels...

  • Replacement 13 Inch Trailer Tire Needed for Old Utility Trailer With 4 Lug Bolt Pattern
    I went out to the warehouse and verified that the Americana Conventional Steel Wheel, # AM20202, is stamped for 1,660 lbs at 65 psi. This wheel has a 4 on 4 inch bolt pattern and is 13 inches in diameter by 4-1/2 inches wide. If you want new tires as well, I recommend checking out the Kenda Karrier ST175/80R13 Radial Trailer Tire, # AM10210, or the Kenda Loadstar ST175/80D13 Bias Trailer Tire, # AM1ST77. These are load range D tires with a weight capacity of 1,610 lbs at 65 psi. If...

  • How To Determine The Axle Rating Of Axle On Boat Trailer
    There are a few different ways to determine the weight rating of your axle. The best way is to look for the axle tag on the center of the axle and you will see the axle rating on that tag. This is the only way that will give you the exact rating of the axle. Now if the axle tag is missing or not readable then you can take the GVWR of the trailer and divide it by the number of axles on your trailer to get a rough idea of your axles rating. Lastly you can remove one of your hubs and look...

  • What Causes Trailer Suspension Equalizers to Sit Unlevel
    What causes the equalizers of the trailer suspension to not sit level can be caused by a few things. Typically it's just a trailer not sitting perfectly level which can easily be leveled by lowering or raising nose of trailer. Or it can be that the leaf springs are too long, or that the hangers were mounted too close to each other. So shorter springs can fix this or spacing out the hangers a little more.

  • Replacement Trailer Tires Size ST175/80D13
    Since you are very close to the 2 lakes you visit you could go with bias ply tires over radials and not really have to worry about anything. The only difference between the 2 styles is that a radial tire has the belts going straight across the tire width wise whereas a bias ply tire will have the belts running at an angle front to back. For some 175/80-13 tires we have some options depending on the capacity needed. Tire # AM1ST77 is an ST175/80D13 tire just like what you have now. To get...

  • 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...
