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"

- AM3S640DX

what a great deal and the video on measuring the bolt pattern was a huge help. Also, my son enjoyed listening to the UPS guy complaining about having to deliver tires :) he obviously thought no one was home. I'd buy them again and will probably replace them all now.

- AM3S640DX

Product arrived as advertised, performance and quality will be determined after some hours of usage. Impossible to give accurate review till them.

- AM3S640DX

Tires and wheels were exactly as stated/depicted and fit perfectly. Transaction was easy, swift, and reasonably priced. I will buy again if need arises.

Got the right tire fast! I won't ship for trailer tires anywhere else.

No problems with tires or wheels. Went from Ct to Fla twice with them all is good

Shipping was FAST! Ordering was easy, I ordered online and then remembered I needed another item, I sent an email and James sent me an email and also called saying my order was on hold until I called them. I called and got the item added to my order. I haven't mounted the tires yet - but I don't see a problem with them. I will do more business with etrailer!

- AM3S640DX

Awesome service

- AM3S640DX

The order was a spare tire replacement and some ramp door lock hardware replacement for my tandem wheel enclosed trailer. The ordering was simple and the arrival at my front door was exactly when specified. Great service. I highly recommend etrailer.

- AM3S640DX

I also purchased the Maxx Haul trailer spare tire carrier and had the spare on in 10 minutes. Everything is solid. I side mounted it since I have a tool box on the front.

- AM3S640DX

Exactly what I needed at the best price and Fast free shipping! Highly Recommended

- AM3S640DX

Product looks very good. I would recommend these trailer wheels to anyone who is interested.

  • 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.

  • 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.

  • Does the Loadstar Tire and Wheel Combination # AM3S640DX Come Balanced?
    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...

  • 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...

  • 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...

  • 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" White Mod Wheel - 5 on 4-1/2 - Load Range C # LHACK120 which...

  • 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 # AS15B45WMQ. The brand of tire on it is Taskmaster but it's a Load Range C like you need so it would work well.

  • 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.

  • 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...

  • 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. If you do have a 5 on 4-1/2 bolt...

  • 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...

  • 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...

  • 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...

  • 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 # AM3S625. 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...
