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"

Ordered as a spare tire for a trailer I have ownded for years. Good quality wheel and tire and received it 4 days earlier than expected. eTrailer service is fantastic. Hopefully wont have to use the tire, but will appreciate the peace of mind having it ready. 576493

I ordered two tires that should have been packaged "separately", not together for better customer convenience. Also I hung around all day for delivery because UPS said a signature was required upon delivery. However, the package was dropped next to my door and without getting a signature the UPS driver just split. Point is, why waste a customer's day if you don't intend to follow delivery instructions to the customer. --Teddy 427347

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 520771

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. 733770

The tires came within days of ordering, they look great. Ordered trailer tires for the pontoon boat, needed galvanized rims. The rims look shiny, husband put them on right in the yard. Ordered the spare tire holder for one of the rim/tires we took off. Worked out perfect for the price, and so far very pleased with our decision to use etrailer. 703377

Took just a little bit longer than expected on delivery, that's only reason not 5 stars. But was late from manufacture. But I was kept informed via email on status, so they were very helpful. And wheel/tire was just as expected so no bad surprises Would purchase thru etrailer again 506217

  • 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...

    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.

  • 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.
