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.

Review from a similar Loadstar Bias in Trailer Tires and Wheels


Replaced my 35+ years-old 4.80-12 trailer tires, thank God I never had a blowout at speed, but the sidewalls were dry-rotted bad enough to get new ones for safety. I switched to the Kenda K353 5.30-12 LR C tires so I don't need to worry about weight limit on my trailer. Haven't towed it more than a few miles, but it feels great w/ the newbies on the axle. 152255

Review from a similar Loadstar Bias in Trailer Tires and Wheels


Ordered 2 boat trailer tires, Loadstar ST175/80D13 bias 8 ply load range D, early CST on the morning of 4/09/14. I selected 5-7 day standard ground shipping at no charge. I was notified within an hour by email that the tires had shipped and that shipping was upgraded to 3-5 days at no charge to me. The tires shipped at 9:39 a.m. CST and arrived 2 days later on 4/11/14 at 11:04 a.m. CST. What more could a man ask for! I already have them mounted on my trailer and I am looking forward to seeing how they perform. I ordered the tires from e trailer because I could not find any 8 ply load range D tires locally in the size my trailer/boat called for. The price was very good also. Thank you e trailer for an excellent experience and great service. I will definitely remain a customer. 124747

I purchased these tires for a home-made trailer that I wasn't sure about. The tires shipped very quickly and the price was great. I just drove over 400 miles with my news tires, and the tines are still on the tires. So far, these tires are fantastic and look like they will last a long time! 139533

Do not say KENDRA anywhere on them, Brand LOADSTAR? 527660

I contacted Americana which manufactures the Kenda Loadstar brand. The bias trailer tires will say Loadstar or a code number with a K in front of it for Kenda.

Review from a similar Loadstar Bias in Trailer Tires and Wheels


Purchased these tires in Jan for my boat trailer. They appeared to be a little deformed which I thought would make them hard to mount. I did not plan to install them right away. After talking with tech support I was reassured they would be OK. Just got around to installing them myself and they worked out just great and they were exactly what I was looking for on my boat trailer. 192751


Comments
After a year of running these tires I could not be happier. They have taken all of the abuse I could give them and no problems. Besides all of the short trips to the lake I have made a trip across the country to Arizona with all of the heat on the highway and still no problems.

  • How To Get the Correct Tire Size For a 1985 Scotty Camper
    You will want to remove the P165/80D13 tires from your camper because they are only a passenger car tire. A trailer tire will be labeled ST before the tire size to designate a special trailer tire. This will mean the tire is designed with stronger sidewalls to handle the extra loads that a trailer/camper will put on the tire. If you look on the 1985 Scotty Camper identification tag it might include the correct tire size that is recommended for your camper. The correct tire size for your...

  • 13 Inch Diameter Tire with 6 Inch Section Width
    The narrowest 13" diameter tire we offer is the Loadstar ST175/80D13 Bias Trailer Tire part # AM1ST74 for load range B, part # AM1ST76 for load range C, or part # AM1ST77 for load range D. These tires all have a section width of 6.6". In order to obtain a section width of 6.0" you would need to go down to a 155/80-13 tire which is a very odd size so if you can give me a bit more insight as to what you are trying to accomplish I would be glad to see if we have any better options for you....

  • Smallest Size Tire Available to Fit on a Trailer for Storage

    Yes, the Loadstar ST175/80D13 Bias Trailer Tire, # AM1ST74, is the replacement size for the B78-13 tire size. You will want to make sure the load capacity of 1,100 lbs. at 35 psi will be sufficient for your trailer. I also have the Karrier ST175/80R13 Radial Trailer Tire-Load Range C, # AM10199, which is a radial tire in that size and has a load capacity of 1,360 lbs. at 50 psi.

  • Option to Replace 155/80-13 Size Trailer Tires
    If you go up to 175/80-13 sized tires, like # they will be about 1-1/2 inches larger in diameter and about 1/2 inch wider. You want at least 3 inches between the tread and fender and an inch between the sidewall to the inside of the wheel well. If you have the clearance it will be better to go with the larger tire than the smaller.

  • What Trailer Tire Size is the Right Replacement for A78-13 Tires
    By definition an A78-13 tire cannot be mounted on a 14 inch wheel since it is a 13 inch tire. Wheel diameter is tricky. When measuring them you do not actually measure the total height of the wheel so you likely have 13 inch wheels. A78-13 is an old way of indicating a tire size. The metric equivalent is ST175/80-13. Since you have a 5 lug wheel it is likely a 5 on 4-1/2 inch bolt pattern. You can measure by following the help article I have linked for you. But if you just need tires...

  • Trailer Tire Replacement for Size A-78-13
    Since your trailer uses lug bolts to secure the wheels to the hubs that means the hubs are hub-centric which means that the pilot hole of the wheel is what centers the wheel to the hub. To replace wheels you'd have to go with wheels that have the exact same pilot diameter as what you currently have so that it centers properly. We can help you replace just the tire though.

  • Can Tire be Purchased Separately of the Loadstar ST175/80D13 Bias Trailer Tire with 13 Inch Wheel
    You can get the tire (and the wheel) separately if you like; you don't have to get the tire/wheel combo of the Loadstar ST175/80D13 Bias Trailer Tire with 13" White Wheel # AM3S030. If you want just the tire from this combo, what you need is the Loadstar ST175/80D13 Bias Trailer Tire # AM1ST74.

  • What Does Trailer GVWR Mean for Maximum Cargo Weight Capacity and Can it Be Increased
    When a manufacturer indicates a trailer's GVWR, which is the most it can ever weigh under any circumstances, this consists of the weight of the empty trailer itself plus the maximum cargo weight you can put in it. Under no circumstances do you want the loaded trailer to weigh more than the manufacturer's rated GVWR. Sometimes trailer makers may install axles whose combined rating is not exactly the same as the specified GVWR. The total axle capacity could be more than or slightly less...

  • Availability of ST175/80D-13 Trailer Tire Minus the Wheel
    You bet! If you were wanting a ST175/80D-13 Load Range B tire such as what's used on the # AM3S030 wheel/tire combo, you'd purchase part # AM1ST74. If you'd prefer the better ride quality and cooler running provided by a radial tire, use part # AM10210. The radial tire is in a higher load range, but it'd still work great for you.

  • Trailer Tire and Grease Gun Recommendation
    When choosing tires, it is important to choose a tire that matches, or exceeds, your axle's capacity. It is also important to note that trailer tires should always be inflated to their maximum psi. The max psi will be noted on the tire's sidewall. If you need a tire with load range B, I recommend the Loadstar Bias Trailer Tire # AM1ST74. This tire has a max load of 1,100 pounds at 35 psi. You will want to double check your bolt pattern, but if you need a tire and wheel with 5 on 4-1/2...
