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"

I ordered 2 replacements tires for my boat trailer. I decided to get rims as well since I needed a spare and with the cost of mounting tires, I figured to break even selling the other original as a spare. My initial impression of the rims and tires is great. In fact, I was even surprised as I expected some tires off a shelf with a layer of accumulated dust. Not the case at all. These were clean and shiny with not even a scuff. I ordered 2 and they were shipped in a box! Frankly, I was impressed and I don't impress easily. Shipping was UPS and tracking was accurate. Product arrived on time. I also want to add that I appreciate the short hold times and informed staff at etrailer. They proved very helpful on my purchase. Very pleased with these tires. 773478

Bought these to replace the small 12in wheels that came with my trailer, and I've been extremely happy with them so far. They look great, added nice clearance for my trailer, and increased the speed rating to allow me to comfortably travel at highway speeds. I've made two long trips with the trailer since I bought these (350+ miles), and was very happy with the performance on the road. Visually, I feel these wheels/ tires have improved the look of my trailer also, so that's a nice plus as well. Would definitely recommend these wheels/ tires. 681159

Review from a similar Loadstar Galvanized in Trailer Tires and Wheels


Blew a boat trailer tire on the way home 2 days ago. Shocked as the trailer is 3 years old and has less than 1000 miles on it. Looked at prices locally to replace one and was disappointed on the wait time /price etc. Checked on line with etrailer and price to order 2 with rims was a lot cheaper for sure. Ordered them and received them in 2 days. Packaged very secure and professionally. “WOW”. Spoke with customer service on a question I had and received 3 emails back in less than a hour. This company is a class act.. Start to Finish. Will be buying more items from them. Nice to find a-company that really does care.. 703589

I went to a local Tractor Supply to buy these first. Only had one and it was a painted steel wheel. I got the pair delivered to my door for $20.00 less and they were galvanized. Exactly what I needed for the salt water. Thanks 437407

Review from a similar Loadstar Galvanized in Trailer Tires and Wheels


I have about 3000 miles on them and they have worked well. They hold air well and track true and straight. I keep them at the recommended pressure and do not overload them. They support a 17' boat that has a total weight of 1900 LBS. That includes trailer, boat and motor. Very little corrosion but I keep them rinsed off after saltwater use and also they are covered from the sun. 784657

Review from a similar Loadstar Galvanized in Trailer Tires and Wheels


I actually bought these to upgrade a trailer I had for sale. It sold quickly, so I didn't get a lot of opportunity to use these tires and wheels before it left my possession. The finish and fitment of the wheels were above what I expected for the price. The tires were high quality and towed nicely. Kenda is a well established commercial tire, and they showed it in the quality of these tires. In short, I would definitely buy this set again. 766624

Shipping was fast, price was good, but the galvanization on the rims of the tire/rim assemblies I purchased looked like it didn’t take well and was sprayed with cold galvanization paint to finish the job. I needed them for a long trip so I didn’t have time to call and ask what was going on. The 679527

    The Loadstar ST175/80D13 Bias Trailer Tire w/ 13" Galvanized Wheel # AM3S040 that you referenced will work very nicely on your 1966/67 Aristocrat Lo Liner. This ST175/80D13 size tire features a maximum load of 1,100 pounds at 35 psi, giving you a combined load capacity of 2,200 for the two tires; more than enough to handle the 1,800 pound GVWR on the camper. This tire also has an excellent speed rating of 81 mph and the galvanized wheel, as you mentioned, will provide superior rust resistance....

  • Do Trailer Wheel and Tires Come Machine Balanced
    The tire and wheel combos we carry are not machined balanced. You can have the tire and wheel combos balanced at a local tire shop if you wanted to. What some manufacturers will do is line up the light spot on the tire with the heavy spot on the wheel. This is a type of balancing but not like how car tires are balanced (with weights on a balancing machine).

  • Speed Rating for Trailer Tire AM3S040
    The speed rating for the trailer tire part # AM3S040 that you referenced is 65 mph. If you wanted a higher speed rated tire we have the part # C17513C which is rated for up to 81 mph. This tire is also a radial which is preferred to the bias ply tire you referenced. The main difference between a radial ply and a bias ply tire is how the tire is constructed. The cords inside a bias ply tire run at a 32 degree angle to the direction of travel, and the cords on a radial tire run at a 90...

  • Tracker Pontoon 13 inch Trailer Wheel Recommendation
    The rivets you described are just for looks and do not serve an actual purpose. For a 13 inch wheel with a 5 on 4-1/2 inch bolt pattern in a galvanized finish the part # AM20234 would work for you. Or if you have a 4 on 4 inch bolt pattern the # AM20224 would work. Galvanized wheels are great for boat trailers since they do a great job fighting corrosion. Or for a wheel and tire the part # AM31994 for a 5 lug wheel and part # AM3S040 for a 4 lug.

  • Trailer Tire and Wheel With 4 on 4 Bolt Pattern
    The largest tire and wheel combination you can get with a 4 on 4" bolt pattern is going to have a 13" rim and 175/80-13 tire. This will give you a tire and wheel that is a total of 24" in diameter and 6.6" wide, which will be 7.9" larger in diameter and 2" wider than your current set up. Depending on the capacity you need, your options for this are the Loadstar # AM3S040, which has a 1,100 lb capacity at at 35 psi or the Loadstar # AM3S130 which has a 1,360 lb capacity at 50 psi.

  • Can a Harbor Freight Boat Trailer with 4.80x8 Tires be Switched to 175/80-13 Trailer Tires
    There are several things to consider when switching to larger tires and wheels on a trailer. First you need to consider the height difference. On a 4.80x8 trailer tire, you are looking at a diameter of about 16 inches. On a 13 inch, like # AM3S040, the diameter is 26 inches. That 8 inch difference means that the top of the tire will be 4 inches higher than your existing tires. You would need to remove the fenders, if equipped, for the tire to fit. You also have to consider width. A 4.80x8...

  • Old trailer rim
    If you somehow got a tire for a 13 inch wheel to fit a 14 inch rim I cannot safely recommend that you drive with that setup. Usually, a 175/70-13 is a passenger car tire. The closest fit for a trailer tire size would be a 175/80-13. For a rim and tire with that size that would fit your 4 on 4 bolt pattern I would recommend the part # AM3S040. This has a pilot diameter of 2.65 inches. The only other option for if you have a different pilot diameter would be the # AM3S101 which has...

  • Trailer Tire Recommendation to Replace Tire Size P155/80R13
    The tire size you have is for passenger vehicles since it starts with the letter P. You shouldn't run that style of tire on a trailer so replacing what you have is the right move. We have a very similar size as 175/80-13 that is rated for trailer use. For a wheel and tire you'd want the part # AM31985 for if you have a 5 on 4-1/2 inch bolt pattern or part # AM3S040 for if you have a 4 on 4 inch bolt pattern.
