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.


Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

Bolt Pattern - Side

Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Tires look good. I wanted these 6 ply to replace the awful soft 4 ply I had which experienced flats due to punctures and unreasonable treadwear. The tires were delivered post haste and well packaged.

  • Recommended ST185/80D13 Bias Trailer Tire for a 2011 Jayco Pop Up
    Yes, you can but we also have a few sets of ST185/80 D13 that will fit your Jayco Pop Up. The Loadstar ST185/80D13 Bias Trailer Tire with 13" White Wheel - item # AM3S331 would be the best option. This is a Load Range D tire with a 1,660 lbs weight capacity. The rim has a 5 on 4-1/2 lug pattern.

  • Tire and Wheel Options for a ST185/80-D13 Trailer Tire
    In general, radial ply tires are better for long highway trips whereas bias ply tires are better for short trips that may lead you offroad. However, we only offer bias ply trailer tires in a ST185/80-D13. We currently have 3 wheel/tire combos in your size all of which have a wheel with a 5 on 4-1/2" lug pattern. I have attached these options for you below but you will want to use the attached help article to ensure you have chosen the correct lug pattern. Loadstar Tire/Galvanized Wheel:...

    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...

  • 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...

I attached a link to a chart to the right that has all of the tire sizes we offer and in the far right column the overall diameter is listed.

  • Replacing Trailer Tires With a Smaller Size
    If you are referring to installing the ST185/80R13 tire on a 15 inch wheel, then it will not fit, unfortunately. That being said, if you are swapping both the tire and wheel, then yes it will work as long as the wheel has the same bolt pattern. You will want to measure said bolt pattern to double check. This should be done measuring from center to center of bolt holes right next to each other. If you get 2-5/8", then the bolt pattern is 5 on 4-1/2" If you get 2-3/4", then the bolt pattern...

  • Do Loadstar 185/80D13 Sized Trailer Tires Need to be Balanced
    Trailer tires do not need to be balanced like passenger tires on a vehicle do. Our tire and wheel combos are balanced by mounting the high heavy spot on the tire so that it is aligned with the low light spot on the wheel. They can be balanced at a tire shop if you'd like but it isn't necessary. The tire and wheel combo you referenced, Loadstar # AM3S331 is a 185/80D13 bias tire that has a Load Range D. It's rated up to 1,725 pounds at 65 psi. Trailer tires should always be inflated...

    I have a few options for you, but at this time we do not offer the Kenda ST175/80D13 Bias Trailer Tire - Load Range C # AM1ST51 as a wheel and tire combination. Instead you could use the # AM1ST51 with the Dexstar Steel Mini Mod Trailer Wheel - 13" x 4-1/2" Rim - 5 on 4-1/2 - White Powder Coat # AM20253 and have a local tire shop mount them for you.

  • Do Trailer Tires and Rims Like Kenda # AM3S331 Come Already Balanced
    The tire and rim combos we carry arrive balanced in a certain way but not like a tire shop would balance a tire. Each tire and each wheel has a heavy spot and a light spot. What the manufacturers do is to offset the heavy spot on one with the light spot on the other to achieve some balance. Balancing beyond this is not necessary since trailers do not have steering or drive axles.

  • Can I Use Radial and Bias Tires at the Same Time?
    If this is just a temporary spare, you can but not for long. We recommend running the same type tire on both sides for safe towing because the different types will respond differently on the road. We need each tire on your trailer to handle the same so we don't have issues on the road. If you decide to go with both bias tires then you need Item # AM3S331. If you want to go with radials you need Item # AM31991. I have radials on my trailer! Radials have more flex to them. Radials grip...

  • Will 175/80-14 Tires Replace 175/80-13 Trailer Tires
    The only difference between a 175/80-13 and a 175/80-14 is the height. The 14 inch model will be 1 inch taller. You need to make sure there is 1/2 inch of space available above the existing tires size to accommodate the larger size. I have included a couple of links on trailer tires for you. Also, a 14 inch tire will not fit a 13 inch wheel so you would need to replace the wheels as well. A 175/80-14 is not a common trailer tire size. If you meant a different size, let me know.

  • Choosing Between Radial or Bias Ply Tires for Boat Trailer
    The only instance where we might conceivably recommend a bias ply tire over a radial tire would be for farm or agricultural use where the tire would primarily be used on non-paved surfaces. This is due to the fact that the thicker sidewalls used on bias-ply tires would offer more stability. For a boat trailer, or any other trailer used on pavement a radial tire is preferable. A radial tire will have a more flexible sidewall, which provides better tread contact with the pavement. Radial...

  • Can a 175/80D13 Trailer Tire be Replaced with a 185/80D13
    Yes, you could replace the 175/80D13 tires on your boat trailer with 185/80-13 tires. There would be hardly a size difference. For that you would want the part # AM1ST79.

    Typically we recommend the use of the same tire size when picking out a spare tire for a trailer, but since the overall tire diameter difference between the two tire sizes you listed is only .3 of an inch you would be fine for just getting the trailer home or to a shop. If you aren't in a hurry to get the spare tire I would recommend that you order in the correct size tire just to be on the safe side.

    Yes, a ST185/80D13 would fit a 13 inch rim that is 4-1/2 inches in width like the part # AM3S331. If you need just the rim you would want the part # AM20232.

  • Replacement Tire Availability to Replace an E78-14
    The ST185/80-13 tire like part # AM1ST79 is going to be 24.4 inches in overall diameter. The tire size ST 205-75-14 that you tried already is 26.3 inches tall so the 185/80-13 would be right at 2 inches shorter in diameter. Assuming your bolt pattern is 5 on 4-1/2 inch the part # AM3S331 would be for a wheel and tire in the ST185/80-13 size and has a 1,725-lb maximum load at 65 psi. You would need to determine the overall weight of the trailer first to be absolutely certain you have enough...

  • 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,...

  • Difference Between the part # AM3S331 and part # AM1ST79
    The difference between the part # AM3S331 and # AM1ST79 is that the # AM3S331 comes with a rim whereas the # AM1ST79 is just the tire. If you need a rim and have a 5 on 4-1/2 inch bolt pattern then go with the combo, if all you need is the tire then go with just the tire. We sell quite a bit of these wheels and tires so I would hate to give you a date since we might have a new shipment in by the time you order. Here's how to determine the date a tire was manufactured.

    Your current 5.30/12 tire and wheel setup has an overall diameter of 21.9 inches and the ST185/80R13 has an overall diameter of 24.1 inches. That means you will have 1.1 inches less of clearance between your tire and fender as well as about 2 more inches of width to your tires. If you have clearance for the bigger tires on your setup this would work well for you.

  • 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...
