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"

The tires n wheels were for my boat trailer. They are excellent. I use my boat all the time. I take it regularly to my favorite lake in East Texas, a 400 mile round trip. Thanks for you great service


Nice tires and rims. Will be great for my jet boat trailer.


They had everything in stocks and was delivered very promptly. It took 2 days from ordering to get my tires and I am extremely happy with them. I will definitely use them for more of my up coming trailer needs.


5+ stars! Excellent customer service, received the tire & wheel assemblies quickly, and the fit like a glove. So happy! Thank you, etrailer.

Product Review: as advertised, great quality. This was the initial purchase for the build of our mini camper. So happy!


Purchased as a spare for my boat trailer. Haven't needed to use it yet, but it looks exactly like my factory tires and has been holding air for a year.


I've been boating for the better part of 20 years and for the majority of that time I've made most purchases at local marinas and shops. When I did a simple search for a common tire I was amazed by the difference in price between my local shop and The reviews looked were overwhelmingly positive so I went for it. I was absolutely amazed by the service, price and incredibly fast delivery time. Also, the tracking system was another major factor in making me feel very comfortable with I'm back on the site tonight to purchase yet another tire as a spare because the other two look so good!! etrailer... you've earned my business and my trust!


Tires are great! The rims are like a foil overlay but still look better than the rust buckets I had on there before! There are a great value and I got 4 tires for what I would have paid for two at a local shop. If you have every changed a tire, you can install these yourself. They come balanced.


Fast shipping and great customer service! Time will tell how the galvanized wheels hold up to Mn salty winter roads.


Bought for our travel trailer. Galvanized looks nice on the trailer. Were cheaper than the white rims, but still great quality. Tires are really nice as well. They came in in their own boxes. They arrived in good shape. I will definately be back when I need tires for my car trailer! Love the service and fast shipping. Was not my first time ordering with etrailer, and won't be my last! Great quality stuff. Best prices around!


Great price worked perfect dropped in the ocean all season no sign of rust make sure you get galvanized bolts aswell.


These tires are OK but I am not sure I would use this grade of product for extended cross country trailering. The rims are as advertised.


Ordered spare tire and wheel for our boat everything matched perfectly and arrived one day earlier than expected. Couldn't be happier


I would love to thank you for all the help received by (MARK extension 72577) my story is i am being Evicted because landlord wants to sell the home, we have been taking care of for the last four years. no places to move. co our 14ft camper will be our home. needed tires for it so ordered 2 form this Great company. but only 1 arrived, in a panic called the company, and was told if it didn't come by the next day (by Amy) waited till after 8 pm the next day, contacted the company and talked to Mark, and what a professional, not only listened to my story with real concern, but he also made sure my tire was here before the move. Thank you from the Bottom of my heart. with so much going wrong in the last 3 years, wife fighting stage3 cancer, me with 3 heart attacks, covid, and Now eviction. Glad something went right for us. again, thank you and God Bless


etrailer is outstanding! I do a lot of e-commerce and frustrated with many companies out there, with pour customer service and lack of supplying goods service and deliveries as promised. I have used etrailer before and received great as promised service. Bought two trailer tires and rims, on Thursday and the following Wednesday they were delivered UPS. Tire and rims mounted and aired in perfect condition!




Purchased a loadstar tire for my 2005 Five Star tandem trailer. Excellent tire for the price, very pleased with this tire brand. What I like is it's an exact match to my original 2005 tire that I'm replacing. The galvanized tire rim looks almost like chrome. I recommend this tire and would buy the same tire/rim if I need another replacement. No issues with shipment, tire/rim came fully inflated and arrived as expected. Thanks!


Bottom line- everything was exceptional from initial ordering and unbelievably fast delivery. Fastest delivery I have ever had and the tire were of exceptional quality too. E trailer has showed me they are the top in customer service and business. Thanks h by the way the price was exceptional too!!


Excellent service and a great price.
sure about putting galvanized rims on my camper but these aren’t dull and look better to me than the stock white rims, tires have an awesome shine as well.


Placed my order and it shipped quickly. Ordered Saturday, came in Wednesday!!! Tire/wheel was great!!!


Great service Great products


Some body said that they were same as the ones I wanted
They are not the center hole is too big, the rims themselves are no where close they stick way out


Love the tire and the rim. Is exactly what my trailer takes. Thank you for your quick delivery and service.


Great product. Just what I needed. Matched with a Fulton Spare Tire Carrier. A happy customer... mostly with the customer service of etrailer. Very professional... received trailer products on multiple orders recently. Fast delivery and outstanding follow-up and support from etrailer staff. Would highly recommend this company and their products for your trailer needs.


Very convenient tires and wheels delivered mounted and ready to put on. Tires went on in a snap. Great way to buy boat trailer tires or trailer tires of all types.


I loved the way etrailer packaged each wheel individually in a sturdy box and shipped to me in advance of the promised time. Would not shop anywhere else for trailer supplies. These tires are clean and brand new.

  • 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.

  • Are 14 Inch Trailer Available With 6-Bolt Pattern For 10,000 Lb Trailer
    The tire/wheel combo we offer that has a 6 on 5-1/2 bolt pattern and has the highest capacity is the Dexstar ST225/75R15 Radial Tire With 15 Inch Wheel, part # AM32680. This is a Load Range E tire that has a weight capacity of 2,830 lbs at 80 psi. If you have a tandem trailer and are planning on replacing all 4 wheels and tires, these would be able to handle the load. This combo measures 28.4 inches diameter when inflated and the wheel rim measures 15 inches diameter and 6 inches wide....

  • 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.

    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.

  • Should Trailer Have Bias Ply and Radial Tires Mixed
    We definitely do not recommend mixing bias and radial tires on the same axle. You can probably get by with mixing bias and radial tires on different axles but we still would not recommend it. Also, if you plan on towing a lot we would urge you to use only radial tires. I have included a FAQ on trailer tires for you to check out.

    Thank you for the photos and we do carry something very similar to what you have, but not an exact match with the Loadstar ST205/75D14 Bias Tire with 14" Steel Mod Wheel # AM3S450. This is the same ST205/75D14, load range C bias trailer tire you have on your trailer, and the wheel is a close match but has just a slightly different design.

  • Replacement Wheel and Tire for a 26-Ft. Travel Trailer
    Your dry weight and payload come out to 7396 pounds. This being a travel trailer, you probably have two 3500-lb axles. As such, each tire will need to have a capacity of at least 1750 pounds, so the tires will need a load range of C or higher. For your ST205/75D14 tires, we have options for load ranges C and D. However, your current tires are bias, and the only load range D that we have are radial, so C will be our option for you. I recommend the Loadstar ST205/75D14 Bias Trailer Tire...

  • Correct Lug Nut Torque for Trailer Wheel and Tire # AM3S450
    Lug nut torque for a trailer wheel like the # AM3S450 is based on the size of the wheel stud basically. 7/16 inch lug nut, 55-65 ft-lb. 1/2 inch lug nut, 75-85 ft-lb. 9/16 inch lug nut, 95-115 ft-lb. 12 mm lug nut, 70-80 ft-lb. 14 mm lug but, 85-95 ft-lb. Most likely you'd be using a 1/2 inch lug so 75 to 85 would be correct.

  • Do Trailer Wheels And Tires Require Balancing?
    Our trailer tire and wheel packages do not come balanced as they do not require it. Trailer wheel and tires are designed to support heavy loads and generally not looked at for a smooth vibration free ride. That is the same reason you virtually never see shocks on a trailer. Vehicles that carry passengers will have the wheels balanced to provide a smooth ride for the passengers inside the vehicle as well as provide a smoother ride for the suspension and steering components.

  • Spare Wheel/Tire Recommendation for 2015 Little Guy 6 Wide Tear Trailer
    I was able to look up the owners manual of your 2015 Little Guy 6 wide trailer and found that it has a tire size of 205/75D14 mounted on a wheel that has a 5 on 4-1/2 inch bolt pattern. So for a spare the Loadstar ST205/75D14 Bias Trailer Tire with 14" Galvanized Wheel # AM3S450 would work really well as it checks all those boxes.

    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...

  • 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.

  • 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...

  • 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.

  • 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....
