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"

A good alternative to 20.5 x 8-10 tires

Great for the price! I think it will work great for hauling my snowmobile around town! Those website really helped me on finding the information for wheels that would fit my trailer.



So far after one year, these tires have been great! Ive traveled out of town hauling things and back and some very decent loads and Ive had no issues. I havent even had to fill them with air yet and they are not even wearing yet

@Tyler Great to hear that, thanks!!


I ordered these because they are advertised as Kenda tires. You sent me Loadstar tires and not Kenda tires. Very dissapointing.


wheel and tire are great and just what I wanted.


Excellent match to the old tire and wheel I'm replacing. Couldn't find this tire on a 5-lug wheel in local shops, etrailer had what I needed.


Bought 2 new tires and rims from etrailer, sow, fantastic price and excellent product. Came in a flash as well. Great company


Wonderful product. Came quickly and product exactly as described. The tires were purchased to replace 30 year old ones on my wave runner trailer.


I have a small boat trailer that these tires are just right for. The trailer sat out for a long time and the original wheels were going to cost to much to fix. This was the easy option. They work great.


Good tires from a very good company, have ordered from your company and have not been disappointed with the service or product


Tires and Wheels seem of good quality and solid. They went on without a problem and look great. Didn't have time for a road test but felt solid on a quick trip up and down the street.


Arrived on time & exactly what I wanted.


Very professionally run business will certainly be back again!


Excellent customer service.


I bought a use jet-ski trailer, after a couple of weeks the tires went flat, noticed they were weather worn. Bought these tires to replace the bad ones. Worked great, looks great. Exactly what I needed at a very reasonable price. Super fast shipping.


Great customer service, competitive price thank you


Exactly as ordered. Fast shipping. Well packed


Ease of ordering , good price , fast delivery, great fit for my etrailer as a spare


Very surprised with how good of a quality these tires are. They are perfect for what i wanted. Very durable feeling.



The tires and fenders i ordered are great quality. After a year of use they held up great and still look brand new. Etrailers is definitely the best route to choose when ordering trailer needs.


Quick delivery, good to go.


Perfect replacement for sea doo yacht club trailer


I will say i will be ordering from e-trailer whenever i need tires for my boat trailers again.The web sight is very easy to navigate and find what i was looking for.Shipping was fast (2 days) i am back on the water.


Still looks and working great


Exactly what I was looking for, great price, great timely shipping. Would Highly Recommend!!


I get what I need at a good price


Have it in your truck when towing.


I mistakenly ordered the incorrect item and will now have to pay $50 to return the items myself. The Company doesn't cover their returns. I've never dealt with a company like this. Makes me think their quality must not be very good if they won't back it.

  • Can Different Tires or Hubs be Installed on a Trailer with Fixed Hub Integral Tire and Rim
    Your set up may be fine on the highway. Make sure that the bearings are well greased and check the tires for any indication of a speed rating. Also check the trailer tongue or frame for any speed limitations. You might be able to switch tires and wheels or replace the hubs but if they are what I think they are then you would not be able to replace them and you would have to instead replace the axle and then get new hubs, wheels, and tires. If the hubs can be removed then I would need...

  • Larger Tire Recommendation for a Horse Trailer to Gain Ground Clearance
    It looks like you would have enough fender clearance to upgrade to a different size tire. Without knowing what size you have it would be hard for me to make a recommendation. But if you check out the link I attached to the right you will see a chart with all of the sizes we of and in the far right column the overall diameter of the tires are listed. If you go with a substantially larger tire you may also need to get a ball mount with less drop to allow your trailer to sit level. I attached...

  • What is 5 on 4-1/2 inch Bolt Pattern for Trailer Wheel
    The bolt pattern of 5 on 4-1/2 inch is the dimensions of the mounting holes of most trailer 5 bolt lug patterns and is what the part # AM30020 that you referenced fits. If you have wheels that are held on with a 5 lug pattern there is a very strong probability you have the 5 on 4-1/2 inch bolt pattern. If you are not sure you can check out the help article that I attached that shows how to determine bolt pattern.

  • Should Travel Trailer Tires Be Aired Up To Max Pressure Stamped On Sidewall?
    Trailer tires like those found on your Travel Trailer should be aired up to the max pressure stamped on the sidewall of the tire. Since you mentioned it is stamped 80 PSI you will want to air them up to 80 PSI. Trailer tires are different than vehicle tires in that they are designed to be run at the max PSI, and running lower PSI causes the sidewall to get more heat which leads to shorter tire life. There is one exception being the Goodyear Endurance line of tires, which are designed...

  • Can Adding Larger Tires to a Trailer Increase Its Capacity
    I am glad you asked these questions. First, to tow a trailer level you need only a ball mount with the proper rise or drop. I have included a link to our FAQ article that explains how to measure for rise/drop and a link to our ball mount main page. For the tires, going to a higher capacity tire does not increase the capacity of the trailer itself. The trailer capacity is set by the axle capacity. There should be a plate or sticker on the trailer tongue or frame somewhere that lists the...

  • Correct Replacement Trailer Tire Size for 1-1/2 Ton Utility Trailer That Uses 215/75R/15 Tires
    The tire size currently on your trailer, 215/75R/15, is a light truck/passenger tire and not a trailer tire. You will be better off with tires made specifically for use on a trailer and rated appropriately for the axle. Keep in mind that the load your trailer can carry will be limited to the lowest rated component in the system - either the wheels/tires, the axles or the trailer frame itself. Increasing the capacity of one component, such as the tires/wheels, does not necessarily increase...

  • Should Trailer Tires Be Inflated to Rating On Sidewall or Per Trailer Manufacturer's Recommendation
    Most trailer tires are capacity tested only at their full inflation pressure listed on the tire's sidewall. Since they're not tested at lower pressures, if the tire isn't fully inflated, the tire's capacity will be reduced by an unknown amount and could easily become overloaded without the user knowing it. Excessive heat build up is what causes tires to prematurely fail. Failure to fully inflate the tire, overloading the tire, and exceeding the tire's speed rating all contribute to heat...

  • Deciding Between Trailer Tire and Larger Passenger Tire for New Camper
    I definitely recommend going with the 13 inch radial ply tire, assuming it is a special trailer tire. I am not sure why the manufacturer would offer or consider putting vehicle/passenger tires on the trailer, but this is not something we ever recommend. Special trailer tires (which will have "ST" in front of the tire size) feature a stiffer sidewall that is designed specifically to better support the weight of a loaded camper/trailer. Even if the passenger car tire is larger the smaller...

  • How Fast Can Trailer Travel on Highway
    Check the tires as they are normally the limiting factor in terms of overall speed. Most of the time they are only rated for 65 mph. If you can't find a speed rating on the tire you'd need to assume the rating is 65 mph and not exceed that figure as it will cause the tires to heat up and potentially fail. For more info on trailer tires check out the help article I attached on the subject. Also, be sure not to exceed the posted speed limit!

  • Does Trailer Wheel Bolt Pattern Matter When Picking Out Replacement Tires
    Trailer tires are not wheel lug specific. As long as the size of the tire is correct for the wheel it would not matter what bolt pattern it has. I am not sure what tire size you have/need but I attached a link to a page that has all of the 12 inch trailer tires we offer. You can select from the filters on the page to show you only the size you need once that's determined or if you can get me the size that's on your sidewall I can help you pick out the best option as well.

  • What Air Pressure Should I Run in My Trailer Tires?
    We recommend that all trailer tires be inflated to the max psi stated on the sidewall of the tire. If the tire is under inflated, the weight capacity is lowered to an unknown amount for that tire. Although running lower air pressures can improve the ride of the trailer with lighter loads, the weight rating that the tire can carry will be reduced. If a heavier load is put on the trailer without changing the air pressure to the recommended amount, the sidewall of the tire could heat up and...

  • What is the Difference Between High and Low Speed Rated Trailer Tires
    Most trailer tires are rated for 65 miles per hour. If there isn't a speed rating indicated on the tire, either an actual number or a letter code, then assume that it is rated for 65 miles per hour. Tire manufacturers test and rate the tires. I think Bridgestone says it best "To receive any kind of rating, a tire must demonstrate that it’s capable of sustaining a particular speed. Industry standards govern the process of reaching and maintaining a given speed during a test." We do have...

  • Can Trailer Tires Be Aired Down for Better Traction on Icy Pavement
    We recommend running the vast majority of trailer tires at the pressure rating listed on the tire sidewall, and for very good reason. You can lower the tire pressure to increase the tire's contact surface with the pavement if you wish, however by doing so you are reducing the tire's capacity by an unknown degree. The tire's listed capacity is at the pressure rating listed on the tire's sidewall, if that pressure is lowered you won't know what the tire's capacity actually is which could...

  • Can I Use Tires that Use Different Required PSI on a 2-Axle Trailer?
    When considering tire PSI for a 2-axle Jayco White Hawk trailer, it is critical that the PSI requirements are the same for all tires. If a tire has a different PSI rating, that is an indicator that the load rating and capacity are different. With that being said, it is important to have tires that require the same PSI. If you need recommendations for different tires for your trailer, feel free to reach out to me with your needed tire size, and I will be happy to make a recommendation for you.

  • Does Tire on AM30020 Wheel/Tire Combo Use a Tube
    The 4.80/4.00-8 tire on the # AM30020 wheel/tire combo is indeed tubeless. The tire has a 590 lb per tire/1180 lb per axle weight rating. The tire is mounted on an 8 x 3-3/4 inch white powder coated wheel with a 5 on 4-1/2 inch bolt pattern. For further details, click the provided link for a product description video.

  • Should Trailer Tire Rated for 90 PSI be Ran Always at 90 PSI
    Trailer tires are unique in that they are designed to be inflated to their max psi rating when cold regardless of the load on them. This ensures you don't create excess heat which would cause the tire to fail over time.

  • What is the Speed Rating for a 4.8x12, 2-Ply Trailer Tire
    If you are using our tires, they are all rated for 65 miles per hour maximum, regardless of how far you are going, unless otherwise noted on the tire sidewall itself. While there is a formula for tire speed based on size and construction of the tire, it is not applied to trailer tires. Trailer tires should also be inflated to the maximum psi rating as indicated on the tire. Because trailer tires are made with a thicker sidewall to handle more vertical load, under inflating a trailer tire...

For example the Kenda 4.80/4.00-8 Bias Trailer Tire with 8" White Wheel - 5 on 4-1/2 - Load Range B # AM30020 are designed for up to 60 PSI so you would want to air them up to that pressure.

  • What Air Pressure Should My Trailer Tires Be Run At
    You'll always want to follow the recommended PSI that is stated on the tire itself. The Kenda 4.80/4.00-8 Bias Trailer Tire # AM30020 you were looking at are designed to be run at 60 psi when cold. Tires on trailers can be changed, so the recommended psi could change depending on which tires you're using, so you'll always want to follow the specs printed on the sidewall of your tires.

  • Can a Trailer with 4.80/4-8 Tires Travel at 50 to 65 MPH
    Your trailer hubs should be just fine for the speeds you listed of 50 to 65 mph. Just make sure the hubs have plenty of clean grease and you would be totally fine. If the tires seem unstable make sure they have the max PSI that the sidewall lists in them at all times. Trailer tires are designed to be run at their max PSI to ensure proper stability and wear.
