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"

Outstanding customer support making certain the proper wheel and tire were ordered for my boat trailer. Placing order on line was easy, order confirmation was immediate, tracking information was provided, and order was received faster than expected. Absolutely excellent customer service, pricing, and product!

After purchasing an awesome aluminum trailer from Nitro trailers in Maine. I realized I needed a spare tire. I looked to Etrailer to find a quality spare tire that would look good and match what I had. I was able to look at some reviews and watch videos to confirm I was making the right purchase. I also needed a method of mounting that tire and found a great mount here as well. While shopping at etrailer I found this nice wheel chock to aid in hauling my motorcycle. This is a great place defined what you’re looking for. In the last two months I’ve purchased a trailer hitch, wiring harness , A bike rack, a cargo carrier, this wheel and tire in the wheel chock. A bike rack, cargo carrier, this wheel and tire in the wheel chock All of them are great

I ordered 2 spare tires different sizes for my boat trailer and utility trailer both came in sturdy boxes Great Job !

- AM3S060

The tires look great. Some of the welds on the inside of the wheels are a little sloppy. It appears that the wheels are possibly refurbished and then coated in aluminum or silver paint. The outside of the wheels are very bright and will look very nice. Time will tell.

- AM3S060

Delivered right on time, item was exactly as described. Bought as a spare to match the ones that are currently on the trailer. Cheapest I found from any other dealer, Will be a returning customer.

Economy Spare Tire Carrier . Works great for the money and very easy to install. I had to make a easy to do adapter because of the area I had to mount it. 2 short peices of pipe and 2 large washers would do it. I have welding capability so I went one step further.

Quick and easy ordering. Tire came packaged well and looks great on the trailer.

  • Manufactured Date of Trailer Tires
    All of our trailer tires like the Loadstar ST175/80D13 Bias Trailer Tire with Wheel # AM3S060 that you are looking at do have a date code stamped on the sidewall. We move through our tire inventory pretty quickly so it's difficult to list the manufactured date since it will likely be quickly inaccurate as those tires get shipped out and new ones take their place in our warehouse. Our tires are also kept safe in a temperature controlled environment. I did go out to our warehouse just to...

  • Speed Rating for Kenda 13 Inch Tire and Wheel Combo # AM3S060
    The tire in trailer tire and wheel combo # AM3S060 is rated for 81 miles per hour. This tire is a Load Range B tire rated for 1,100 pounds at 35 psi.

  • Will ST175/80D13 Load Range B Replace My Older A78-13 Tires
    The ST175/80D13 load range B tires like part # AM3S060 are actually 2 inches larger in diameter then the old A78-13 tires. The section width is the same as the old tire. As long as you have clearance it shouldn't be an issue. You need 4 or more inches from the top of the tire to the fender to not interfere with suspension components. The ST175/80D13 tires load range B is the closest tire size to the A78-13 tires that we carry.

  • Will the Loadstar 13" Steel Wheel Fit on 10" Timbren Brake Drums?
    Yes, the Loadstar ST175/80D13 Bias Trailer Tire with 13" Galvanized Wheel # AM3S060 will fit the 10" Timbren brake drum. You might see some conflicting answers and this is most likely due to either people using car wheels that would have a different offset or using aluminum wheels. The aluminum wheels are thicker and therefore have a smaller diameter inside the hub area.

  • Spare Wheel and Tire for Little Guy Camper in Size 175/80-13
    For a spare that you could use for your trailer that has 175/80-13 tire size the part # AM3S060 would work really well. It's the correct bolt pattern and tire size and is pre mounted like you wanted. Trailer wheels are not typically balanced though so it is not balanced. This is a steel wheel setup that would work well as we do not have an aluminum design that matches what you have.

  • Should I Get Higher Load Range Tires Than Needed
    The higher load range tires, part # AM31242 that you looked at, really won't help or hurt you. They don't protect any better against nails or anything else that can damage them compared to lower rated tires like part # AM3S060 and you certainly don't need the extra capacity. On the other hand the flexing of a tire doesn't have much bearing on the quality of your ride. Sure it'll have some but your suspension should take up most of that. If it were me I'd likely go with the D rated tires...

  • Boat Trailer Spare Tire Replacement for Older B78-13T Tire Size
    You want all of your tires to be the same whether they are installed on the trailer or will be used as a spare. The Loadstar ST205/75D14 Bias Trailer Tire with 14" White Wheel # AM3S440 you're looking at is a bit larger than your B78-13T tires so we need to find you a 175/80-13 tire instead. For your application I recommend going with the Loadstar ST175/80D13 Bias Trailer Tire with 13" Galvanized Wheel # AM3S060 as the galvanized finish protects the best against water and this has a Load...

These are a 5 on 4-1/2 bolt pattern with a 3.19" pilot diameter. The Loadstar ST175/80D13 Bias Trailer Tire with 13" Galvanized Wheel, # AM3S060 that you linked to has that same 5 on 4-1/2 bolt pattern and 3.19" pilot diameter.

  • Can You Put Smaller 4.80-12 Tires On a Jetski Trailer To Make Launching The Boat Easier?
    There are a few things to consider when moving to a smaller tire on your double Jetski trailer. First is the bolt pattern for the new wheel. You will either need a 4 on 4" like the Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30630 has. The other common bolt pattern is a 5 on 4-1/2" like the Loadstar 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30670 has. Next is if the smaller tire has enough weight capacity for the Jetski's and trailer weight. Both tires...

  • How to Choose Replacement Special Trailer Tires for 2004 Bass Tracker 185 Boat Trailer
    The primary things to consider when selecting replacement trailer tires are the total weight load they must carry and the type of driving you'll be doing, say either off-road travel deep in the woods or mostly on the interstate at or near the speed limit. These questions will help you determine which tire weight Load Range you need and whether a bias or radial tire will be better. Radials are superior for higher-speed highway travel since they flex more and run cooler; but a bias tire...

    The galvanized wheels are really ideal for a boat trailer. They are corrosion resistant, and have a nice look as well. The Loadstar ST175/80D13 Bias Trailer Tire with 13" Galvanized Wheel - 5 on 4-1/2 - Load Range B # AM3S060 is a great option for your boat trailer as long as you have the matching bolt pattern on your hubs.

  • How to Carry Spare Tire on Apogee Adapt-X 500 Folding Utility Trailer
    The Apogee Adapt-X 500 folding utility trailer, like # AT74FR does not include a spare tire holder. You can certainly add one, but the problem lies in finding a spot to install a spare tire without interfering with the trailer's ability to fold. The best spot to mount a spare tire carrier would be the front wall of the trailer bed, above the trailer tongue as shown in the provided photo. I'd recommend using the Fulton Hi-Mount tire carrier, part # FSTC1000301. The carrier provides enough...

    The closest we have is the part # TA73RR which is the tire you want on a silver powder-coated rim with a 5 on 4-1/2 inc bolt pattern. We have similar setups like the part # AM3S060 that does use a galvanized wheel but it uses a load range B Kenda tire and not the Taskmaster. We also have the # AM31994 with a Kenda Load range D.

    I have two tires that fit your needs. The Taskmaster # TTWSF48012C is a 6-ply Bias Ply tire rated for up to 990 pounds per tire (Load range C) and speed rated (M) up to 81 mph. The Taskmaster # TT48012C is a radial trailer tire also load range C and speed rated for 81 mph. Personally, for trailers, I don't think that radials bring much additional benefit over bias ply.
