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"

So far excellent..last tires lasted 15,000 mi. on Mini-Mate motorcycle camper over rough roads. These are going to Alaska and in load range C for gravel and bumps. Wheels have perfect paint and the 3 raised dots in rim recess to hold my new baby moon hubcaps. Popped them on new wheels/tires today and they fit over bearing buddies and seated more firmly and tightly with than I've experienced before with no rattle at all. The tires installed more easily because the center hole was smaller than many old sets of wheels and lug bolts aligned easily and exactly. The Kenda 6-ply have been good in past but was very pleased with last tires(CST) the rubber stayed soft and didn't crack. My spare is also Kenda 6-ply and hasn't shown cracks through 4 sets of tires on the trailer. The new ones look to be of same high quality. They arrived quickly and was able to install between work commitments. After trying to order same on other sites for over a week and get info as to plies/wheel type, etc., I stumbled on eTrailer site and 'bingo' all taken care of and perfectly!

Its now a year and they are at the wear bars! However, they traveled rough chip and seal and dirt and mud roads through Yukon and Alaska round trip from Colorado. They have 1200 miles on them..5000 more than the last sent went and on sandpaper roads to boot! I want another set of these as soon as they can be shipped!


These wheels and tires are ideal for highway use for long trips. They say right on tire "High Speed Trailer". With the trailer with no cargo, it weighs 530 lbs. With a 600 to 700 lb load I am at capacity with old tires (590 lbs each). These new tires are Load Range C vs my old tires Load Range B. My new tires are 745 lbs range each. They have two extra plies on the side wall. I also updated the springs with the 750 pound range 3 leaf version I bought also from etrailer. The key to success is to inspect the trailer each time you use it for small starting cracks in trailer frame, loose hardware, low pressure in tires, lights, etc.

The way that trailer tires are rated has changed over the years. Currently, the ply rating given to a tire doesnt necessarily reflect the number of layers or plies used to construct the tire. This tires rating is equal to the rating given to the rating a 6 ply tire under the old rating system.


Nice new tires and wheels for my 50 year old boat trailer that has been off the road for 22 years! Thank you for having what I needed in stock.

I havent had these on the road yet. So far I have only moved the trailer around my property. I expect to start road trips this summer. Thanks again for having what I needed.


I'm getting 10,000 miles+ from these and like the fact that the installed rims have the 3 little nubs to accept moon discs on my motorcycle trailer. I pull through some nasty places and this keeps my 'Bearing Buddies' grease from picking up dirt. Got 2 sets wheels last time so am set for a while. On an Alaska 10,000 mile round-trip over bad chip and seal and horrible dirt these held up great. Be sure to inflate properly for your application as they come inflated to 60 lbs. (for boat trailers) and my little camper requires 27 lbs. when loaded. Test run them over your wetted driveway to see that you are running on the entire tread, not only the middle.


The wheel & tire were an exact fit of the old wheels. The powder coat will last many years. The wiring harness in the picture was also from It simply just plugged it in (I loved that part). That's so much easier than hard wiring a harness to a vehicle.


This is the second set of these Kenda 6ply Hi Speed rated trailer tires I have purchased from

They’re used on my Vintage 1988 Coleman Columbia Camper I pull to road racing permanent tracks throughout the US during the summer.

The first set lasted 5,000 miles. The team there are the best and the prices are amazing.


These wheels were a great replacement for my "tag-a-long" trailer that I will pull behind my motorcycle. I dressed them up a little as you can see in the picture by adding little black dots to the rim. From a distance they look like regular 12" or 13" rims with holes in them.


This site was great to purchase from! I have an older trailer for our small levy boat and wasn't even sure what size to choose. The information on this site was readily available, very detailed, easy to understand, and easy to find. This allowed me to select the wheel and tire combo that was a perfect match to my application giving me the confidence I needed to make my purchase.

I highly recommend this site for your trailer needs!


It's the right tire and wheel for a great price


Great durability (previous purchase) & great turn around on delivery time.



Still doing fine &amp I pull every weekend.


Very nice unit. Replaces old tire and rim on small boat trailer. Quick delivery and packaged very well. Thanks etrailer.


needed new tires for atv trailer researched internet and local
e-trailer still cheaper than local and free shipping over 100$ beat local store by almost $30 and delivered in 2 days wow keep up the great deals
recommend checking e-trailer first


I working on a 1956 cusman eagle. I had to make a template because the bolt patern thatI need is 4 on 3.5" . also had to increase center hole from 2.5" to 2.75". no one had this as needed, I had found a wheel correct for aplication but $200 a wheel. delivered on time by ups.


So far so good traveling 100's of miles at 65+ mph carrying a small boat.


Great wheels, good price. Ordered from etrailer many times, always happy with the product and service : )


These tires and wheels are a perfect fit for my kayak trailer. I wanted to have a spare and for the same price as other dealers had for 1 was able to purchase two! The shipping was very fast and as soon as the snow clears a bit I will be able to confidently get my kayak to all the Northern California lakes. Thank you !


Great service and tires arrived fast!!!


Delivery was fast and the wheels and tires were great


The tires were delivered quickly. These tires have more plys, a higher load rating and lower price than tires i can get locally.


AM30040. Top quality. Very satisfied.Load range C, very sturdy. Using this tire and wheel package on a converted boat trailer to utility trailer, used for hauling quads, riding mowers,and motorcycles.


Quality tire and rim for the price


Great price for these tires and wheels. They arrived quickly, fit perfectly.


Great replacement wheels and tires... replaced for a kayak trailer with galvanized hubs for use in Saltwater... quick shipping and great followup!


The last tires lasted 10,000 miles on my time-out trailer. I pull it with my Harley and the wife keeps it loaded heavy. These are the exact same tires so I expect the same results. Ordering was easy, shipped in a reasonable time. I am pleased.


I normally do not do reviews. I think your service was excellent and I am very satisfied with the experience of your service. Thanks!

Tires and wheels continue to work great.

  • Kenda 4.80/4.00-8 Bias Trailer Tire/ Wheel Combo As Replacement for Existing 4.00-8 Tire
    The 4.00-8 tire is an obsolete size that is no longer manufactured. The name 4.80/4.00-8 is used so people will know that the new size which has a tread width of approximately 4.8 inches is the correct replacement that would be slightly wider than your existing tire. The # AM30040 tire/rim combo you referenced would be an acceptable replacement for your existing tires, as long as they are replaced in pairs. The 4.80/4.00-8 tire is designed for a 3-3/4 inch wide rim and is 16.1 inches in...

  • What Could Cause Vibration At 50 MPH On Trailer W/ New Axle and Hubs
    That is definitely odd, but I would lean towards a hub/bearing issue. I didn't see you mention this step, but when installing the new hubs/bearings did you tighten the castle nut nice and tight to seat the bearings fully, and then loosen it up to get the correct bearing preload? If not I would start there and complete this step and see. The hubs should not free spin, but should have very minor resistance. If that all checks out, I would make sure all of the U-bolts holding the new...

You'll need to check these as there is no info on a 1983 Cox trailer but so long as the 745 lb per-tire weight capacity is ok and you have a 4 on 4" bolt pattern you can use the # AM30040.

  • Is The Kenda 4.80/4.00-8 Bias Trailer Tire with 8 Inch White Wheel, # AM30040, Rated For The Highway
    The Kenda 4.80/4.00-8 Bias Trailer Tire with 8 Inch White Wheel, # AM30040, is highway rated. Trailer tires have a speed rating of 65 mph. Trailer tires are designed for carrying a maximum load at all times, so to do that they are reinforced in the sidewall. With the sidewall being reinforced, that causes the heat to build up more quickly at lower speeds with a load on the tires, so you will not want to run a trailer tire at higher speeds than the 65 mph speed limit.

    The tire and wheel capacity for the Kenda 4.80/4.00-8 Bias Trailer Tire with 8 inch White Wheel # AM30040 that you referenced is rated for the individual tire and wheel, not per axle (2 wheels and tires). You should note that the wheel capacity is 910 lbs and the tire capacity 745 lbs at 90 psi. This means a couple things. First, your towing setup is always limited to the lowest rated component in the setup, so in this situation the tire is rated lower than the wheel so the overall capacity...

  • Can Vehicle Tire And Wheel Be Used On Pop-Up Camper
    It is not recommended to use a vehicle tire on a trailer or camper because they have weaker sidewalls and can fail. Trailer wheels typically have a zero offset and vehicle wheels have an offset so there could be clearance issues with that as well. Also, the bolt pattern could be different for the wheel as well. I would stick to trailer wheels and tires on the trailer to be on the safe side. If you let me know what the wheel bolt pattern is on your trailer hubs I will be glad to make some...

  • Benefits of Using Higher Load Range Trailer Tires
    Increasing a trailer's tire size can offer some potential advantages but it can also cause issues. Using a wider and/or larger diameter tire can mean clearance issues within the fender wells and at the leaf springs. It is important to have enough clearance above the tire tread to allow for suspension travel; at least 3-inches but more is better. The most common reason folks want to use larger tires is to reduce the chances of a blowout, which is certainly a very good motivation! But there...

  • How to Select Wheels and Tires for Older Motorcycle Trailer
    We can help you select new tires and/or wheels for your older motorcycle trailer. The trailer should have a sticker or plate with its VIN and other information including its gross vehicle weight rating, GVWR. GVWR is the most the trailer can weigh when it is loaded. Once you find this information you will simply divide that weight capacity by the number of tires on the trailer; by two for a single axle and by 4 for a tandem axle trailer. So for instance if the trailer has a GVWR of 2000-lbs...

  • Can Camper Trailer Weight Capacity Be Increased By Changing Tire Load Range Rating
    Thank you for the photo of your camper trailer. When it comes to a trailer's weight carrying capacity the lowest-rated part of the trailer - either the frame, axle, hubs, wheels or tires - will determine if more capacity can be added. If the tires were the lowest-rated component then changing them to another size or simply to a higher load range in the same size could give you more capacity/safety margin. But if the tires are not the "weakest link" then upgrading them does not add capacity...

  • Comparing 4.80/4.00-8 Trailer Tires and Speed Rating of 4.80/4.00-8 Trailer Tires
    Tire and wheel combo # AM30040 is the same tire as # AM10004. They are both made by the same company and both have the same rating and load range. The trailer tires that we carry are rated for 65 miles per hour. You do not want to exceed the speed rating because it will build up excess heat. Trailer tires already have a thicker sidewall than passenger vehicle tires and this adds to the heat they generate. So you do not want to increase the heat by going over 65 miles per hour. I have...

  • What Pressure Should Trailer Tires Actually be Ran At
    Trailer tire pressure ratings are different from vehicle tires. With trailer tires you want to always inflate them to the max psi rating when cold and as long as you aren't exceeding the weight capacity and speed rating any psi fluctuation will be totally fine and not need to be monitored. If you under-inflate them (sounds like you might have been) they will build heat up quickly which eventually leads to failures like blow outs. The # AM30000 should be ran at it's 60 psi rating. It...

  • Jet Ski Spare Tire and Wheel for 4.80/4.0-8
    The Kenda 4.80/4.00-8 Bias Trailer tire with 8" Wheel Part # AM30040 is a good option. This will give you the proper size you are looking for when it comes to matching your other tires. I like that this assembly comes put together instead of having to mount a separate tire and wheel. This is a load range C bias ply tire so it is specially designed for being a durable trailer tire. This will hold up whether you are carrying one or two jet skis.

Going with a higher capacity tire will not increase the gross trailer weight capacity.
