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 was hauling a tractor on my trailer when I got a flat tire. Its not fun taking the wheel off the trailer and finding a tire shop to fix the flat while the trailer sits on the side of the road. I am using this rim and tire as a spare tire. The product is as it was described, and it was way cheaper than what I could find locally near Beaver Falls PA. The shipping was very fast. I will definitely be doing business with this company again. I give them an A+++


Ordered 4 trailer tires/wheels and they got here already inflated darn close to specified psi! Great customer service, the kind I haven't seen in quite a while.


The rim discription tells you the diameter and the bolt pattern but not the width. The rims are narrower than my other trailer tires that I own and that makes them have a smaller foot print. I wish it would have said that in the discription I would have ordered wider rims and been willing to pay more. That being said they are what I ordered and go round and round.

I am sorry to hear that these rims are not wide enough for your application. I see that the dimensions are listed on our site, 15 inch diameter by 5 inches wide. I have sent your information over to our customer service department for them to get in contact with you to help you find the correct size rims you are needing.
-- Etrailer Expert Katrina B - 08/25/2022


Tires and rims were just as expected - fit up was fine.
Finish on the rims looks pretty good!
Readying for a long road trip - good insurance policy to have fresh rubber on the road


They are beautiful. Just got them on and at first I didn’t think they were going to fit, they are taller then the ones on the shop. We are moving the shop on Saturday morning can’t wait to see how smooth they ride. Thank you again Alex. Shipping was almost instant I was so totally surprised I need tire covers now


The website is so easy to use. Found what I needed and ordered it quickly. Shipping was free and fast. Saved me from wasting tons of time and eliminated lots of hassle. Thanks


They arrived much sooner than expected. This makes 10 tires and rims we have purchased from you and service has been great. I liked the price on the last four better but because of inflation I understand the increase. Maybe in four more years when I need more tires the price will be back to normal.


The web site was easy to use and my order was sent to me very fast. I’ve ordered from etrailer before and I’m very satisfied with the quality of the products and the fair prices.


Wheel and tire exact match to my original. Arrived on time as promised. Good experience with etrailer and I'll shop etrailer in the future.


Being a spare, I don't USE the tire/wheel (yet) but a good price, they look good, and holds air for a year so I think it's a win.


perfect match for my existing tire on my trailer. when i purchased the trailer it did not come with a spare which you should always have for that time that you get a flat in the middle of the California desert


Good quality and price. The only negative is that the mount came out of the package and was bolted to the tire rim. No parts lost fortunately


Looks like a good assembly. I bout it for a spare.


Perfect spare tire and rim for my utility trailer. Product was as described.


Excellent price and great service, product was delivered when etrailer said it would.I will definitely shop at etrailer in the future.


As described!! Perfect. Arrived within a few days. I’ll definitely be ordering from etrailers again


Product was promised by a certain date and arrived by that date. The link to track my order was very helpful. Will definitely recommend to others.


Good packaging; shipped timely. Trailer tires: good price and good quality.


Excellent product, Excellent communication, Excellent Shipping!!


Price, shipping and quality of product all get an excellent review.


have not used yet, but very satisifed with quick delivery and site of this productis very satisifactory..


The tire with wheel appears to be of excellent quality and is exactly as advertised. I am always impressed with etrailer's explanation of their products and their exceptional customer service. I will keep coming back.


Well the shipping was good and service. But what’s wrong with the picture


Great quality, low cost, delivered quickly, it's a tire, and it rolls

  • What Does the 75D Mean in a Trailer Tire Size ST205/75D15
    In a tire size the second number is the aspect ratio. The aspect ratio is the percentage of the sidewall height relative to the width of the tire. The width is the first number; in this case for # AM3S640DX the width is 205 mm. The sidewall is 75 percent of 205 mm. The D is indicating the tire is a bias ply tire as opposed to a radial tire. The difference is in the orientation of the plies or belts in the tires' construction. On a radial they run straight across the tire whereas in a...

  • 15 inch Trailer Rim and Tire Recommendation with ST205/75 D15 Tire

  • Does Loadstar ST205/75D15 Bias Trailer Tire with 15 Inch White Wheel # AM3S640D Come Already Mounted
    Yes, the Loadstar ST205/75D15 Bias Trailer Tire with 15 Inch White Wheel - 5 on 4-1/2 - Load Range C, # AM3S640DX, does come with the tire already mounted on the wheel. They are not balanced but you can have them balanced at a local tire shop if needed.

    All of our combination tire and wheels like the Loadstar ST205/75D15 Bias Trailer Tire w/ 15" White Spoke Wheel # AM3S640DX come ready to install. They are balanced in the way trailer tires are balanced which is different than the vehicle tire balancing process that includes adding weights. There is a high (heavy) spot and low (light) spot marked on the tire and then the manufacturer ensures the high/heavy spot of the tire is aligned with the wheel valve stem hole. This is all that is...

  • Should Utility Trailer Spare Tire be Same Size as Current Tires?
    I recommend having a spare wheel and tire that is the same size as the wheels and tires currently on your utility trailer; using a different size would create a situation where your suspension would be imbalanced, which you want to avoid even for a short-term situation. You also have different styles of tires on your trailer, and you'll want those to match up as well. Your current tires are bias, which you can tell by the "D" in the 205/75D15 size you referenced, while the 205/75R14 are...

  • What is the Warranty on the Loadstar ST205/75D15 Tire 3S640
    The Loadstar ST205/75D15 Bias Trailer Tire that comes on the # AM3S640DX has a 5 year warranty against defects. The warranty provided on tires is going to vary from manufacturer to manufacture but belt separation would likely be covered in most cases within that time period.

  • Can I Use the AM3S640DX to Replace 7.75 x 15 Trailer Tires
    Yes. The # AM3S640DX would be a good choice to replace the 7.75 x 15 tires on your 1976 Prowler trailer. This tire/wheel combo has an 1860-lbs per tire capacity, so you'll be well over the 4000-lbs GVWR of the trailer and for the 7.75 x15 tire size you mentioned, the ST205/75D15 tire is the closest modern tire size. Since this is a tire/wheel combo, I do recommend making sure that your trailer has hubs with a 5 on 4-1/2 bolt pattern so that the wheels are compatible. If you find that...

  • Do you have 205/75/15 trailer Tires Available with a 5 on 4.75" Lug Pattern
    The Loadstar ST205/75D15 Bias Trailer Tire w/ 15" White Spoke Wheel part # AM3S640DX is a great choice. It offers the very common 5 on 4.5" wheel lug pattern. I do not have anything available in a 5 on 4.75" pattern available. I have linked a guide to measuring the lug pattern to ensure this wheel will match. If it is different please let me know. The current pricing is available on the website for you to check out.

  • Can I Put Larger Wheels And Tires On My 2014 Forest River R-Pod 179 Travel Trailer?
    It looks like your 2014 Forest River R-Pod 179 travel trailer came with 14" wheels that have 5 on 4-1/2" lug pattern along with 205/75R14 tires. There is not a real benefit to upsizing your wheel size in this application, aside from looks or to gain clearance. You may be able to upsize to Loadstar ST205/75D15 Bias Trailer Tire w/ 15" White Spoke Wheel - 5 on 4-1/2 - Load Range C # AM3S640DX which would be the same width as your current wheels/tires, however, it would be 1" taller.

  • Recommended ST205/75-15 Trailer Tire With White 5-Bolt Wheel For Spare
    Thanks so much for all that info, and we can get you exactly what you need, which is a ST205/75-15 trailer tire with a white 5-bolt wheel and a load range in the capacity you need. There are actually two options; one is a bias tire and the other is a radial tire. Bias tires are really only best for shorter trips and agricultural use while radial tires are best for normal, everyday roadways. The reason for that is bias tires have cords which run diagonally while radial tires have cords...

  • Recommended Replacement for 7-14.5 Trailer Tires
    The only replacement tire size option we have for your existing wheels is the Kenda K391M Mobile Home Tire part # AM10327 which is going to be about 1" wider or 1/2" per side than your existing tire. The 7-14.5 tires are not really used anymore as they are an older style so if you would like to upgrade to a more common style with new wheel, I recommend a 205/75D15 like the Loadstar ST205/75D15 Bias Trailer Tire w/ 15" White Spoke Wheel part # AM3S640DX which is designed for a 5 on 4-1/2"...

  • How to Determine 5 Lug Bolt Pattern of Trailer Wheel
    To measure a 5-bolt lug pattern you measure from the center of a bolt hole straight across the center of the wheel to right between two lugs on other side. OR the way I prefer is to measure from the center of a bolt hole to the outside edge of either of the bolt holes furthest from it. This will get you the same measurement. I attached two pictures that show this as well. Since you mentione 4-1/2 inch you most likely have the very popular bolt pattern of 5 on 4-1/2 inch since this is...

  • Can Radial And Bias Ply Tires Be Mixed On A Trailer?
    It is not recommended to mix bias ply and radial tires, so you would not want to use the Loadstar ST205/75D15 Bias Trailer Tire w/ 15" White Spoke Wheel - 5 on 4-1/2 - Load Range C # AM3S640DX to replace a flat ST205/75R15 tire. Bias ply and radial tires track and perform differently which can cause an unstable ride, and can wear tires quicker. I recommend going with the Castle Rock ST205/75R15 Radial Trailer Tire w/ 15" Silver Mod Wheel - 5 on 4-1/2 - Load Range C # LHACK121 which has...

  • Spare Tire and Wheel That is Size ST205/75-D15
    We have tires which are going to be exact fits. Your tires are ST205/75-D15 (C), so you will need that size bias tires (which is what the "D" stands for) with a load range of C (which, of course, is what the "C" stands for). As for your rims, it depends on what your bolt pattern is. Most likely it is going to be 5 on 4-1/2, though if you are unsure please take a look at the help article on determining the bolt pattern of your wheel that I've attached.

  • Replacement Tire Recommendation for ST205/75D15 Tire with Load Range of C
    For your application I recommend going with the Loadstar ST205/75D15 Bias Trailer Tire # AM1ST92 which is a Load Range C (1,820 lbs at 50 psi) 6 ply rating tire that also has an impressive 81 mph speed rating. This is a proven tire that is backed by a 5-year limited warranty. If you're needing this on a wheel then I recommend checking out the combo # AM3S640DX which is the same tire just no a white spoke wheel that has a 5 on 4-1/2" bolt pattern.

  • Recommended Spare Tire for Cargomate Trailer with 15 Inch Wheels
    I was able to find some information on your Cargomate TXLEEH58SA trailer. From what I found, it appears your tire size is 15 and your load range is B based on the factory tires. We have only have a load range C option and it is the Loadstar ST205/75D15 Bias Trailer Tire with 15" White Wheel - 5 on 4-1/2 - Load Range C # AM3S640DX. This is rated for loads of up to 2150 lbs at 50 psi, it's okay to increase capacity. The great news is that these have a max speed of 81 mph rather than...

  • Availability of Trailer Tire Size 205/75-15 Mounted on White Mod Wheel
    The small circles around the wheel like you described indicate that you have a mod style wheel. So for a wheel in that style that has a 5 on 4-1/2 inch bolt pattern with a bias-ply 205/75D15 mounted on it you'd want the part # TA47VR. The brand of tire on it is Taskmaster and it's a Load Range C like you need so it would work well.

  • Difference Between 205/75D15 and 205/70R15 Tires
    You are correct, the 205/70R15 tire is not a trailer tire. This tire is 26.3" in diameter, 8.1" wide and fits a 15" wheel with 5-7" of width. Your 205/75D15 tire has an overall diameter of 27.1" and fits 15" wheels with 5-6.5" width. Tires are able to fit on rims of different widths to a certain extent so that is probably the difference you are seeing. Since these are a different height I would recommend replacing the 205/70R15 tire so your trailer is level. Since I do not know what wheel...

  • Which Timbren Axle-Less Suspension System for On and Off Road Trailer?
    Great question. The standard 2K system # ASR2KHDS01 is for standard highway driving only. The Heavy-Duty 2K system # ASR2KHDS02 will be compatible with wider tires for more of the combination use you are seeking. The # ASR1THDS01 listed for Off-Road Tires has suspension that is more robust for up to 2,200 lbs and has a longer arm for a smoother ride over a rougher terrain. For your application, I recommend # ASR2KHDS02. It will handle better for your fair bit of highway driving as...

  • Recommended Spindles, Hubs, Wheels and tires for 1200 lb Piece of Agricultural Equipment
    If a 2000 lb capacity per pair of spindles would work for you, I'd go with the # TRU94FR spindle along with the # AKIHUB-545-2-LFEZ-1K complete hub which includes bearings, races, the grease seal, the dust cap and lug nuts. The hubs are even pre-greased. The hubs are sold individually. For a compatible wheel/tire combo, use # TA53VR. This is a 205/75-15 bias-ply tire mounted on a white spoke 15 inch wheel with a 5 on 4-1/2 inch bolt pattern. If you're looking for something with a higher...
