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.

I installed Kenda Loadstar K371 tires on Strongway garden trailer because I was tired of getting punctures in the standard low cost tires I was buying off the shelf at my local hardware store. The Kenda tires might be overkill but I have not had a puncture since installing them. After a year of use I still love them.


The tires are a perfect fit on my Rubbermaid yard trailer. I couldn't be happier!


I had to replace the tires on the utility trailer I tow behind my garden tractor. I wasn’t sure what to expect when I ordered these Kenda tires as I had no previous experience with them. I was very pleasantly surprised with them. They are far better than the old tires I took off the trailer and have performed better than expected. I am completely satisfied and would definitely buy them again!!

A year later I am still thrilled with these tires!! They have held pressure perfectly and are still carrying whatever load I put in the trailer. I’d buy these tires again in a heartbeat!!
Dennis - 06/28/2022


The tires have been great. They were put on a log splitter that sits outside all year and they are doing great.


Perfect for the car hauler trailer


My wheelbarrow got a flat...again. So I tried a different route. It's a trailer tire but I noticed it is 8in, the same as my wheelbarrow. This is a much more robust tire than the ribbed [tire] that typically lives there. I think the load rating is like 750lbs, way more than I will ever put in there. Anyway if you want to put a truly heavy duty tire on you wheelbarrow, this is it. etrailer had the best price and it got here fast.


Jessica was absolutely wonderful and saved the day to get the tires and rims I needed. She went above and beyond in all aspects in the sale and shipping of the tires and rims I desperately needed in a short time frame!! Would definitely recommend and use in the future. Again a huge thank you to Jessica and!!


I have an old wheelbarrow that takes this size tire. This trailer tire is much higher quality and carries much more weight than an ordinary wheelbarrow tire. Installation was simple using the old tube. I am very happy with this product and the service.


Easy install. Sidewalls were not squeezed tight so it was easy to mount on the rim and inflate. As a retired mechanic, I have confronted tires that were God-awful to mount and inflate. These required no tools other than soap and water.


Quick handling and shipping. Received my tires just a few days after placing my order. A+++


These are durable trailer tires. I have used this brand for a few years now and am very satisfied with their performance. I mount and inflate my own tires and find it easy using a screwdriver and crowbar to dismount old and mount new. A little bit of silicone spray allows the bead to seat nicely and will not damage the tire or rim. If the tire is compressed from shipping, I suggest using a rope windlass or ratcheting strap around the perimeter of the tire while inflating to force the bead against the tire rim. The bead will usually "pop" into the wheel seat at between 12 and 20 P.S.I. 4/8/2022 MDP


It has an odd shape to the tread area. If it doesn't straighten out after it is aired up, I will be returning it. Thanks

I wanted to let you know that that when the tires leave the manufacturer they are tied together and shipped on large pallets. Since they are compressed together to save space, they look a bit out of shape or smooshed when they are delivered. There is not anything wrong with the tire, once it is mounted on rims and inflated, they will be perfectly safe and will perform very well for you.
-- Etrailer Expert Jenny N - 11/10/2022


I have been ordering online for over 15 years, and this is the very first company that shipped the same day ordered, ON A SATURDAY! I fully expected a Monday shipment, but was delighted by the same day service.
An added bonus, there was no way I could beat the price locally, even with the cost of shipping and tax. Thanks!


Hassle free service!

Absolutely no problems with the tires! Satisfied customer!
Vince - 11/13/2022


These tires are perfect in every way. What I received was exactly what I was expecting. I would absolutely recommend etrailer for tire needs.


I love the quality of the tires and their rapid delivery.


Not exactly fresh tires according to the Born On Date. I suppose they are an upgrade to my current 20+ year old trailer tires. I wish companies would advertise Born on Date, but that the price you pay for on-line sales.


I'm very satisfied with the trailer tire I ordered. I really needed two but wasn't sure if the tire would fit. The tire fits perfectly so I'm ordering another today.


Nice new trailer tire, reasonable shipping cost


I ordered some tires for my log splitter and they arrived earlier then expected. Smooth transaction and they were also cheaper then [online stores].


Great fit & price! Also arrived a day early. Very good experience for a first- time customer. Will definitely use this site again.


It is cheaper to buy only the tire if your rim is fine. This should make a great spare. E trailer does a good job


Excellent response. Quick delivery. Just what I needed. No issues whatsoever.


Fast shipping and quality product


Got my order moved up couple days saveing the day for the duck boat this weekend very appreciated

  • Can a 5.7 x 8 Trailer Tire Replace a 4.8 x 8 Tire
    As long as you have the additional clearance required by the bigger 5.70 x 8 you should have no problem installing this size tire as a replacement for your 4.8 x 8. The 5.7 x 8 will be 1 inch taller and .9 inches wider. If you measure your trailer and find that you have enough clearance for the additional height and width you should have no problems. I attached a link to all 5.70 x 8 tires we offer.

  • Availability of a 4.80/4.00 x 12 Trailer Tire and Wheel Combo
    What you have to remember is that the 1.2 inches taller # AM10002 tire will actually only be 0.6 inches closer to the fender because the extra height is distributed evenly above and below the axle. Take a look at the trailer and see if there is space enough for the extra 0.6 inches (just under 5/8 inches). If so then you can go with a 4.80-12 tire. If there is not space enough then you would either have to go to a smaller tire size (all the way down to an 8 inch) or modify the fender or...

  • What are the Dimensions of a 5.70 x 8 Tire
    The overall diameter of a 5.70 x 8 tire and wheel is 18.1 inches. The overall diameter of the tire that you referenced # AM1002 is 16.1 inches. I have included a link to the 5.70 x 8 inch tires that we currently have available. Of these the section width of these tires is 5.8 and 5.9 inches, and the overall diameter is. I have included links to a couple of informational articles about trailer tire and sizing for your reference.

  • Does Kenda K371 Load Range B Bias Trailer Tire # AM10002 Require an Inner Tube When Mounted
    The Kenda K371 Load Range B Bias Trailer Tire # AM10002 that you referenced does not require an inner tube. It is not recommended to use a tube with a bias-ply trailer tire due to the resulting heat build-up that could cause tire damage. This Kenda trailer tire exceeds DOT specifications, has a maximum load rating of 590-lbs at 60 psi inflation and fits rims that measure 8 x 3-3/4-inches. When fully inflated this tire will have an overall diameter of just over 16-inches. This and all trailer...

  • How to Measure a Trailer Tire to Determine the Correct Replacement Tires
    Your current tire should have some type of code on it that indicates its size. The Kenda K371 Bias Trailer Tire, # AM10002, is size 4.80/4.00-8. It fits on 8 by 3-3/4 inch rims. It sounds like the 46 and 27 inch measurements you have given are the outer and inner circumferences around the tire, and not the diameter across the tire. The diameter of the Kenda tire is 16.1 inches from the bottom, center of the tire to the top center of the tire. The section width is 4.6 inches. The section...

  • How to Choose the Correct Hub and Wheel for a Trailer with a 4.80-8 Tire
    To make sure we choose the correct wheel and hub for your trailer, we are going to need a little more information about the spindle on your trailer. I assume the 1.250 shaft that you mention is the spindle on your trailer. Most trailer spindles are tapered and the spindle does not usually have the same diameter the entire length of the spindle. To make sure we choose the correct hub for you, we will need a few measurements from your spindle. We will need the diameters for the inner and...

  • How to Determine Bolt Pattern for a Trailer Wheel Replacement
    It sounds like the new 12 inch wheel and tire combo you have is designed to fit a different bolt pattern hub than what your trailer currently has. The bolt pattern of a wheel tells us the number of lugs (or bolt holes) and the diameter of the circle the lugs sit on. For example, a 5 on 4-1/2" bolt pattern lets us know we need a wheel with 5 lugs that are spaced out evenly on a circle that has a 4-1/2" diameter. Most likely your trailer either has a 4 on 4 inch bolt pattern or it has a...

  • Can I Replace a 4.80-8 Trailer Tire with a 4.80-12 or 5.30-12 Trailer Tire
    You can replace a 4.80-8 trailer tire with a 4.80-12 or a 5.30-12 trailer tire, but there are a few things to consider before making the change. First, 4.80-12 and 5.30-12 tires are going to have a larger overall diameter than a 4.80-8 tire, by about 4 inches, so you will want to make sure your trailer has enough room in the fender well to accept the larger tire and wheel. Also, a 5.30-12 tire will be about 1 inch wider. The width will not make as big of a difference as the diameter,...

  • Which is Better for Highway Use 4.80-12 or 5.30-12 Trailer TIres
    The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The wider a tire is the more contact it makes with the road and the more contact with the road the more you are going to feel bumps as you travel. A 4.80-12 tire will be 20.5 inches in diameter whereas a 5.30-12 tire will be 21.9 inches. You would...

  • Can 5.30-12 Trailer Tires be Used to Replace ST205/65-10 Tires on a Snowmobile Trailer
    The more narrow the tire the less contact with the road it will have which means the ride will be smoother. But I would go with the tires the trailer manufacturer recommends for the trailer. It should indicate the proper size on the tongue or frame somewhere. The ST205/65-10 tires, if they are a load range D or E will have a higher capacity than all sizes for a 5.30-12 tire so you would be limited to the lower capacity if you did make the switch. The 5.30-12 will only be about 1.4 inches...

  • What is the Speed Rating for Trailer Tires
    The thing about trailer tires is they are almost all rated for a max speed of 65 miles per hour. There are a few brands out there that do have higher speed ratings, but we do not carry those. I did attach a page to the right that has all of the rim and tire combos we offer that have 4.80 X 12 tires. You will need to know what your wheel bolt pattern is first before you pick out the correct rim. I attached an FAQ to the right that details how to determine this. I also attached an FAQ article...

  • Could Trailer Tire Size 4.80-12 Replace a 5.30-12 Tire
    The two tire sizes you mentioned fit the same size wheels so yes, a 4.80-12 would replace a 5.30-12. The difference is the tire will be slightly narrower and right at 1-1/2 shorter in diameter. The part # AM10002 that you referenced could work as long as it would give you enough weight capacity at 590 lbs at 60 psi. I attached a review video for this tire for you to check out as well.

  • Diameter/Height of 4.80/4.00-8 and 5.70-8 Tires
    Actually the overall diameter/height of those tires are different by a few inches. The overall diameter of a 4.80/4.00-8 tire is 16.1 inches. The overall diameter of the 5.70-8 tire is 18.1 inches. The outer diameter of the # AM10002 tire you were looking at will be 16.1 when properly inflated. I have linked you to some Help Articles on determining tire size for your convenience.

  • Is it Recommended to Go to a Smaller Wheel and Tire Size on a Trailer
    The problem with going from a larger wheel size down to a smaller one is primarily that you lose a lot of weigh capacity when you do this and also the tire sizes for each wheel size don't both give you the same overall tire diameter. The 13 inch tires are much smaller than the 15 inch wheel tire sizes. I would recommend you stick with the size you have. I attached a chart that has all of the tire sizes we carry. You can see the overall diameters in the right column and the capacities...

  • Will a 4.80-8 Trailer Tire Fit in Place of a 4.00-8 Tire
    Yes, a 4.80-8 tire will fit in place of a 4.00-8 tire. That is why a lot of times you will see both sizes in the product's title or description and even on the actual tire, such as # AM10002. This is a load range B tire rated for 590 pounds at 60 psi. I have linked a video review of this tire for you.

  • What Is Maximum Highway Speed For Kenda K371 Bias Trailer Tire
    The maximum speed rating for trailer tires is 65 MPH. The B rating is the load rating for the tire, which is 590 pounds at 65 PSI. You always want to have the tires of your trailer inflated to the maximum PSI rating at all times. If they are not inflated to maximum PSI, the thick sidewalls can heat up and wear faster than normal. I have linked an FAQ on trailer tires that you may find as a good reference.

  • Things to Consider When Changing to a Different Tire Size on a Trailer
    When considering a different size tire for a trailer there are a couple different things to think about. The first thing to consider is clearance. With a smaller tire you might end up with more clearance in the wheel well, but you might end up with the trailer being too low to the ground. You could potentially drag the rear of the trailer while driving through a valley or going up a hill. Another thing to consider is how the height of the tires will affect the sway of the trailer. A taller...

  • Will a 5.30 x 12 Trailer Tire Fit the Same Rim as a 4.80 x 12 Trailer Tire
    Yes, a 5.30 x 12 tire will fit the same rim as a 4.80 x 12 tire. Both tire sizes fit on a 4 inch wide rim. There are a couple of things to consider when changing tire sizes. First, the larger 5.30 will be approximately 1.4 inches taller than the 4.80 so you will need to make sure that you have enough clearance above the tire. The 5.30 is also wider by 1/2 an inch so you will need to make sure there is clearance behind the tire as well for the new size. Also, the capacity of the larger...

  • What Does the 4.00 Mean on the Kenda K371 Bias Trailer Tire 4.80/4.00-8
    On the Kenda K371 Bias Trailer Tire, # AM10002, the 4.00 that you see is there so that people who have the older 4.00x8 tires, which are no longer available, will know that this size is compatible with their trailer. So if you are replacing 4.80 x 8 or 4.00 x 8, it will fit.

  • Is a 4-Lug, 4.80-8 inch Tire and Wheel Adequate for Trailering a 400 lb Ariens Garden Tractor
    It really just depends on the weight capacities of your rim and tire. The tires we sell that are the same size as yours have capacities of 590 lbs and 760 lbs depending on the load range of the tire. One of these tires would be adequate for your setup. You will need to check the weight capacity of your tires and wheels to determine if your setup is adequate. The weight capacity of the tire should be stamped on the sidewall along with the maximum psi recommendation for the tire. You always...

  • Swapping Out P155/80-13 Tires for 5.30-12 Tires on PWC Trailer
    The 5.30-12 wheel/tire combo you referred to would measure about 21 inches in diameter, while a 155/80-13 tire would measure about 21-3/4 inches in diameter. Going with the 5.30-12 tires will lower your ride height by a tiny bit, but not enough to cause any problems. The two are similar enough in size that they should work just fine. Swapping out to different tires isn't a bad idea. The P155/80-13 tires you're currently using are passenger car tires, which we usually don't recommend for...

  • Should Inner Tube Be Used with Kenda K371 Bias Trailer Tire # AM10002
    I want to start by thanking you again for your purchase. We truly appreciate your business. The Kenda K371 Bias Trailer Tire, # AM10002, that you purchased do not require a tube. This tire is specifically designed for use without a tube and using one would cause too much heat build-up and result in premature failure of the tire. Since our trailer tires are not designed to use the inner tube, we do not carry them.

  • Tire Pressure For 4.80/4.00-8 Load Range B
    First, try checking the tire's side wall, the recommended psi should be listed. For our trailer tires with a 4.80/4.00-8 size, a 3-3/4 inch rim, load range B, the maximum load is 590 pounds at 60psi. Each tire manufacturer could have different recommended psi for their tires, so it is important to find information for your tire's manufacturer. It is important to remember to inflate your tires when they are cold, and to inflate them to their max psi.
