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 tires and wheels along with adjustable receiver hitch on Monday. Everything arrived on Wednesday. Great service and good products.

  • Karrier ST205/75R14 Radial Trailer Tire, part # AM32156 Recommendation for Boat 4200 lb w/ Trailer
    The main difference between a radial ply and bias ply tire is how the tire is constructed. The cords underneath the tire are run in different directions. On a bias tire, the cords run at a 32 degree angle from the direction of travel and on a radial tire, the cords will run at 90 degrees from direction of travel, or across the tire from wheel lip to wheel lip. Because of the construction of a radial tire, the tire has more flex and will allow for more ground contact. That will improve...

  • Are the Trailer Wheel and Tire Combos Already Balanced
    Every tire and every wheel has a high (heavy) spot and a low (light) spot. When the manufacturers mount the tires on the wheels, they try to offset the tire high spot and the wheel high spot to provide some balance. However, to achieve an actual balanced tire, you would need to take them to a tire shop and have them professionally balanced.

  • Can ST205/75R14 Trailer Tires be Replaced with ST205/76R15 Trailer Tires
    You can potentially switch from ST205/75R14 tires and wheels to ST205/75R15 tires and wheels but you first need to make sure that there is enough clearance all around the existing tires for the larger size. The 14s that you have now are abut 26.3 inches tall and about 8.1 inches wide. The 205/75-15s will be about 27.1 inches tall and about 8.1 inches wide. The width is the same but the 15s will be about 0.8 inches taller which means that there needs to be clearance above the existing...

  • Replacement Tire and Wheel Size ST205/75D14 for a 2010 Trailmaster Boat Trailer
    Yes, tire and wheel combo # AM3S450 will fit your 2010 Trailmaster boat trailer. This is basically an exact match for what you have. The D in the size (ST205/75D14) indicates a bias ply tire. If there was an R instead of a D that would indicate a radial tire. You always want the all the tires on a trailer to be the same construction type, either all bias or all radial. If you did end up needed a radial you would want tire and wheel combo # AM32156.

  • Availability of a Galvanized Trailer Wheel for a 205/75-14 Tire
    The 205/75-14 tire size indicates that it is for a 14 inch wheel. According to our resident tire expert, the listed diameter of a wheel is measured from bead to bead where the tire rests against the lip of the wheel. If you are measuring the face of the wheel, you have to account for the half inch or so of lip on each end. Our tire expert went out to the warehouse and measured a 14 inch trailer tire and came up with the correct 14 inch diameter when measured in the location on the...

  • Tire Replacement Recommendation for a H78-14 Trailer Tire
    From the research I did it looks like your H78-14 tires are 27.8 inches in diameter. Which the closest size we offer that is compatible is the ST215/75R14 like Karrier ST215/75R14 Radial Trailer Tire # AM10229. This tire has a diameter of 26.8 inches which would be about an inch shorter in diameter than what you have. Is that too short? What problems will you experience if your tires aren't as tall as your current ones? Ground clearance? If so, you might be interested in a Dexter axle...

  • Replacement Wheel and Tire Recommendation for Size F78-14 with Galvanized Wheel
    The modern size equivalent for the tire size F78-14 is the size 205/75-14. So for this size on a galvanized wheel Taskmaster Mod Wheel and Tire part # AM3S450. What's great about the Taskmaster tires is that they are rated for higher speeds at 81 mph whereas most are only rated for 65. The tire has a ply rating of 6 and a 1,760-lb max load at 50 psi as well.

  • What is the Backspacing of the Wheel in Tire and Wheel Combo AM3S450
    The 3-7/8 inch measurement is the backspacing for the tire and wheel combo # AM3S450. Sort of an easy way to determine backspacing on a wheel with a zero offset is to take the width, 6 inches, divide by 2 to get 3 inches, then add approximately 1/2 inch for the lip to get 3-1/2 inches. It will get you close but the most accurate way is to remove the tire from the wheel, lie a flat board or yardstick across the wheel, then measure from the mounting surface to the bottom of the yardstick or board.

  • Replacement ST214/75-14 Trailer Tries for Existing Boat Trailer Tires Size H78-14
    Great news! I can help you find replacement tires for your existing boat trailer tires. Thanks to the information you provided from your tires, I was able to determine your tires are size H78-14 special trailer tires. This is an older trailer tire size, so for the current sizing system you will want a ST215/75-14 size tire. Our most popular ST215/75-14 size tire is the Taskmaster ST215/75R14 Radial Trailer Tire, Load Range D # TTWTRTM2157514D. This radial tire is a great option for...

  • Replacing H78-14B Trailer Tires on a Triad Boat Trailer
    There are a couple of different size modern equivalents to the 78-14 tire size. But for an H78-14, you would need to use an ST215/75-14, see link. If you just want tires, we have bias tire # AM1ST90 and for a radial we have # AM10229. Make sure not to mix radial and bias tires for best performance and longest life of the tires. I have also included a link to our tire FAQ article for you.

  • Replacement Tire and Wheel for Karavan Trailer 2990-72-12
    From what I was able to research, your Karavan 6x10ft Aluminum Utility Trailer is model number 2990-72-12 and came with 205/75/D14C tires. There is only 1/2" width difference between the stock tires and the # AM3S560 , but in order to use them you would need to upgrade both tires/wheels so that you have a matching set. With that being said, the correct replacement tire for your trailer is going to be the Loadstar ST205/75D14 # AM3S450 , which is a load range C tire that has the exact tire...

  • Which Trailer Hub Works With the #42 TruRyde Spindle Part # TRU57FR
    I do have an option for you but there is not a trailer hub available that will work with the #42 TruRyde Spindle part # TRU57FR and allow for you to use a wheel with a 5 on 4-1/2" bolt pattern like the Loadstar ST205/75D14 Bias Trailer Tire with 14" Galvanized Wheel part # AM3S450. Therefore, you will need to choose a new wheel/tire to work with the trailer hubs that we do have available for this spindle which use a 6 on 5-1/2" bolt pattern.

  • Matching Radial or Bias Tires on a Trailer
    You will always want the tire size, load range, and construction, to match on your trailer. Using tires that are different can lead to more of a load being put on the smaller size tire/tires and cause tire problems to occur. In your case the tire size (ST205/75-14) is the same but the tire construction is different. With different tire construction the radial tire would run cooler than the bias ply tire and the tracking of the trailer would also be different with the two different tires....

  • Smallest Tire Available with Capacity Greater Than 1600 lbs for Pontoon Boat Trailer
    If you compare two tires of the same manufacturer and tire size, load range B tires should all have the same capacity, same for load range C or D. A 205/65-10 tire like part # AM1HP56 has a 1650 lb capacity at 90 psi. Two tires would give you a 3300 lb capacity. Wheel/tire combos are also available. For a 4 on 4 bolt pattern, use part # AM3H470 or for a 5 on 4-1/2 bolt pattern, use part # AM3H490. To get a higher capacity than that, you'd need to go with a larger tire like a 215/75-14,...
