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.

@PeteT We're happy to hear that!

I purchased these to replace the tires on my boat trailer. They fit the rim but seemed slightly smaller than the tires I took off. The only other thing I noticed is that the tires were made a few months apart and had slightly different lettering. The font or design was different between the two. Since I only had one on each side, it didn’t really matter. Nobody will ever notice it. The tire was as described and should fit the need perfectly. I have already pulled it a few times but nothing heavy, just a couple hundred pounds max including the trailer.

So far, so good. Still holding air and track great down the road.

I purchased one of these tires for my wheelbarrow last Spring. I live in the land of goatheads, prickly pear cactus, and other thorns; previous tires just didn't last. Very frustrating when you go to get the wheelbarrow and the darn tire is flat! This one has survived the Spring and all Summer without a hitch, flat or one single problem. I would highly recommend this option to anyone with a similar problem!
Can you tell which tire I like?

Thanks for writing this review!While shopping for new upgraded tires for my garden cart I read this and decided to upgrade my wheelbarrow tires at the same time.The difference between the normal wheelbarrow tire and this one is amazing and I expect it to be well worth the time and money to do it!SRC



by:

Speedy delivery and high quality products.
I
ordered the RV tire cover as well as 5 trailer tires.
I had to replace the awful and extremely poor quality tires that came with the Farm-Tuff Utility Trailer — 2,200-Lb. Capacity, Model# 03813 wagon that i ordered from Northern Tool.

Tires still in great shape, even having endured a long snowy mountain winter.

Good tire at a reasonable price. Very quick shipping. As usual with any shipped tire, one of them was very misshapen and was difficult to seat and air up.

It has been a year since I mounted these tires and I continue to be pleased with them. No issues.



by:

Once mounted the tire face is a bit more rounded then expected. Would have preferred a flatter face, but these tires look good and will work just fine.
The packing and shipping boxes were great.



by:

Size is perfect, haven’t put many miles on it yet, I hope it lasts a long time. Handled fine at 55 mph with 70 lbs on the trailer.



by:

The tire looks good I have not had a chance to mount it yet



by:

I am very pleased with my tire order process, the speed of delivery, and the tires themselves. I used these tires as replacements for the original tires on my Triton LTX jet ski trailer. Exact fit and one load range better than I had. Very pleased.



by:

My tires arrived quickly which was a plus as they were needed before I could travel. I had planned on taking ‘before’ photo’s but it seems I only took after photo’s. After installing and after driving 300 miles. The tires did well and I am pleased all the way around.



by:

A little out of shape to seal on rim. The ratchet strap trick worked. Although the 1”trap was not wide enough.



by:

They ride really smooth look great, my only problem was getting the tires on the rim. The guy I got the boat from and myself took over one hour to put on one tire . I ended up taking them to a service station where they said those were some of the hardest tires to mount to the rims they ever mounted. but we finally got them on the trailer and they are smooth as silk.



by:

Great product, great customer service, a pleasure to do business with!



by:

Awesome service. Extremely fast shippin g.



by:

Tire arrived on time, and is excellent quality. It was impossible for me to mount on the wheel; one side was convex and the other concave, so getting rim contact to contain air promised to be a problem, but I could not even force one side over the wheel rim. Took the tire and wheel to a local tire business, and was fortunate to see it done. The burly operator was able to force tire on wheel, but couldn't establish rim contact. After a futile struggle he attached a VERY high pressure air tank and injected a blast of air that was more like an explosion, forcing the tire to balloon out and make rim contact. After that, no problem...

The tire has proven to be of good quality and is wearing well.



by:

I love, love, love this trailer tire. I have purchased and installed six of these tires, on vintage Cushman 24volt Industrial Electric vehicles (3 wheelers) and they are a GREAT addition. Classic tread design, Art Deco, Saw-Tooth side-wall styling, and rugged tire design - a perfect tough tire that adds a great finishing touch to your vintage restoration project.

Still enjoying these quality tires, no issues!



by:

I ordered these tires, which came at a great price, for my small lawnmower trailer that may some day haul a motorcycle, and I must say I am more than pleased with product and service. The tires are all they are supposed to be and after selecting standard delivery they arrived in two days. Now that's service. I put these tires on in about two hours with a tire iron and a screw driver--no problem--I'm hauling mower. Need a tire? These guys are the tire people for me.

still a good purchase. will buy again soon for boat trailer.



by:

A decent tire, a bit tricky to mount & get sealed on a tubeless rim. But no problems in service after that.



by:

Just put them on my trailer, time will tell on how they will perform. Delivery was very prompt and no surprises ...everything was as expected hat's off to E-trailer.I am upgraded tires to haul Motorcycles
on highway.

I havent had a bit of trouble tires worked well under tow.Etrailer was great to order from and answered questions I had,I would do biz with them again!



by:

Quality looking tires- to soon to give overall review



by:

I am completely satisfied with my tires I purchased for my log splitter. from trailer. The tires arrived earlier than predicted (with an unrequested free shipping upgrade).

I checked the manufacturing date stamped onto the tire and the date was within an acceptable range, unlike some online sellers, who push the envelope on shelf life.

I upgraded from a Load Rating of A to C, which is overkill but hopefully will extend the life of the tire. The C rated tire was less expensive than the A rated version offered by other sellers.

I plan on buying more equipment tires from etrailer in the future.



by:

Exactly what I wanted. Dozens of regular tire stores and auto parts stores do not carry these small size trailer tires. Even RV, camping, and boating dealers don't; they just have larger tires/wheels for bigger rigs.
I spent an entire morning searching around San Diego to replace a trailer tire that had blown out on the freeway. Fortunately I had a spare tire/wheel with me but was reluctant to get back on the road without another spare.



by:

Had a blow out on the boat trailer due to the fact the tires were 45 years old. Got online and ordered new tires from etrailer and they were hear by the time I had the rims repaired and painted, I was amazed. I was amazed on all the thing they had for sale.

The only thing I was shocked on was when I call and the sales girl did not know what a inner tube was, but like I said they do have many items



by:

After having issues with the trailer tires on the trailer that I tow behind my touring motorcycle, I was pointed to these. I mounted them myself, used Dynabeads to balance them, and they went 2000 miles without a problem. Something the other tires couldn't do. Thank you for the recommendation.



by:

This really is the best tire for small trailers. This trailer is towed behind a motorcycle and all other tires have come apart even in as little as 100 miles. Typically, we run 3000 miles on a motorcycle trip and the tire is cost effective enough to be changed for every trip. I have not had one of these come apart in 100 degree plus heat at 70 mph.

  • What Is The Difference Between The AM10004 4.00/4.800-8 and a 4.80/4.00-8 Tire Dimensions
    While the 4.00/4.800-8 was once widely sold, very few companies produce them anymore and the 4.80/4.00-8 like # AM10004 is the only size you will often find. While the 4.80/4.00-8 is generally wider and taller, they were close enough in size to be interchangeable in the past. Most tire manufacturers eventually quit carrying both sizes and have gone to just carrying the 4.80/4.00-8. I have linked you to some Help Articles on tire dimensions as an additional resource.

  • Torque Specs for Trailer Wheel Lug Nuts That Use 17 mm Socket
    If you are using a 17 mm socket for your trailer wheel lug nuts then you actually have 12mm lug nuts. The proper torque specs for this size is 70 to 80 foot pounds, as indicated on the attached chart. A 17 mm size lug nut would be very odd on a trailer but if this is truly what you have please let me know and I will be happy to try and find the correct specs.

  • Are Tire Weight Capacities Per Tire or for a Pair
    Yes, trailer tires are rated by tire. So for example, the Kenda 4.80/4.00-8 Load Range C Tire, part # AM10004, is rated up to 745 pounds at 90 psi. Two tires on one axle are rated up to 1,490 pounds. You still need to verify the weight capacity of the other components of your trailer. You'll always be limited by the lowest rated piece of the puzzle.

  • Are Tubes Needed For The Kenda K371 Bias Trailer Tire - 4.80/4.00-8 - Load Range C # AM10004
    Tubes are not needed in the Kenda K371 Bias Trailer Tire - 4.80/4.00-8 - Load Range C, part # AM10004. All of our trailer tires are tubeless tires. You will not want to use a tube in a tubeless tire because that would double the heat buildup inside the tire which will cause the tire to fail. The heat is increased because a tubeless tire is built with a liner on the inside of the tire. When you put a tube inside the tubeless tire, on top of that liner, that will cause the extra heat buildup. The...

  • What Tire Pressure Is Recommended On 4.80/4.00-8 Load Range C Trailer Tire For Highway Speeds
    The tires should be inflated to 90 psi on the highway as well as other roads, regardless of load size. The problem is that under inflating a trailer tire will lead to degradation of the tire. On trailer tires, the side walls are thicker than on car tires so they can handle more vertical load. An under inflated tire side wall will heat up more often and quicker and will lead to early wear and possible failure of the tire. The best thing to do is to follow the rating on the tires and inflate...

  • Lug Nut Torque Rating for a 5-Lug Trailer Wheel
    The correct torque for installing lug nuts on your 5 X 8 trailer's 5-lug wheels will depend on the size of the lugs. For a 1/2-inch lug the torque spec ranges from 75- to 85-ft-lbs. For a 9/16-inch lug the torque spec ranges from 135- to 145-ft-lbs. Please refer to the linked chart. You will want to avoid using an impact wrench or any other tool that cannot provide measured force. Use a torque wrench for accurate results. You should re-torque them at 10 miles, 25 miles, and 50 miles, and...

  • What is the Best Way to Determine the Correct Bearings on a Snowmobile Trailer
    The definitive way to determine the bearings needed for any trailer is to remove the hub and inspect the bearings. The bearing numbers will be stamped into the metal of the bearings. If you have a round axle and can determine the diameter of it, along with the wheel size, bolt pattern, and any other information you can provide, I may be able to determine what the correct bearings are. I have included a link to a video that might help if you decide to take the hub off.

  • 4.80/4.00-8 Tire Recommendation for Swisher Trail Cutter
    The Kenda K371 Bias Trailer Tire # AM10004 should work fine for you since it is the same tire size as what you have on your brush hog. The slight rim width difference shouldn't matter for your application. We do not carry tubes though, so you will have to find them somewhere else or reuse your current one if it is still good.

  • Troubleshooting 20 Year Old Trailer Tires Not Staying on Wheel
    Trailer tires really need to be replaced at 6 years of age. Your tires being 20 years old is going to be a huge problem. If the size you need is 4.80/4.00-8 like the part # AM10004 you referenced this would be a great option as a replacement. If you have a different size let me know. You also need to be sure to keep the tires inflated to their max psi at all times too.

  • Tire Pressure Recommendation for a 4.80/4.00-8 Load Range C Trailer Tire
    Most likely the recommended tire pressure for the Load Range C 4.80/4.00-8 tire you have is 90 psi. However, you should check the print on the side of the tire as the max pressure should be listed there. It is important to always have trailer tires inflated to their max psi as a trailer tire is only good for its full capacity when it is inflated to its max psi. I attached an FAQ article on trailer tires for you to check out also.

  • Do All 4.80/4.00-8 Tires On a Trailer Need To Be the Same Brand
    Generally speaking, you do not have to use the same brand of tire on all sides of a trailer. The only things that must be consistent are size, load range, and speed rating. That said, different brands can have different tread patterns like you mentioned which can then create uneven wear patterns as well as tracking issues so it would really be best if all sides were the same brand. For a 4.80/4.00-8 trailer tire, we have the Kenda K371 Bias Trailer Tire part # AM10004 which comes with...

  • What is Lug Nut Torque for 14 inch Trailer Wheels
    For a 14 inch trailer wheel with standard 1/2 inch wheel studs the torque you'd need to use is 75 to 85 ft lbs. It is correct you would want to torque the lug nuts of the wheels in a few stages or passes. I would get them all fully seated into the wheel first, do a round of getting them pretty tight, and then do a final pass with a torque wrench taking them to the full torque rating. All of these done in a star pattern. The lug nut torque video we have on our site does overlook this but...

  • Does a Spare Tire have to Match the Regular Tires on a Boat Trailer
    Having a different rating and psi rating on a spare is permissible so long as you do not have to go far to get a new tire and as long as the capacity of that tire is enough for the capacity of the trailer. Ideally, your spare tire should be exactly the same as the regular tires to avoid any compatibility issues. Not only should the spare be the same size, capacity, load range, and have the same psi rating but it should also be the same construction; either bias ply or radial. Tire #...

  • What is the PSI Rating for Kenda 4.80/4.00-8 Load Range C Trailer Tire
    The Kenda trailer tire # AM10004 is rated for 745 pounds at 90 psi. You should always inflate trailer tires to the maximum psi they are rated for. This is because trailer tires are constructed with a thicker side wall to handle more vertical load. If under inflated that thicker side wall will generate excessive heat and cause tire failure. I have included a link to our help article on trailer tires for you.

  • Do Replacement Tires for Cycle Mate Trailer Need to be Balanced
    The Kenda K371 Trailer Tire # AM10004 can be balanced but it isn't necessary to balance them like vehicle tires, however they can be if you'd like. The tire and wheel combos that we sell are balanced by lining up the light spot on the tire with the heavy spot on the wheel. This is a type of balancing often used for trailer tires.

    You have asked a question that has confused many people. The tire size 4.80-8 and the tire size 4.80/4.0-8 are absolutely identical. The numbers reference a new system versus an old system of measurement. The new system is the first number 4.80-8 and the other number was the older system. We reference both numbers because many people are reading the numbers directly from their current tire when seeking a replacement.

Provided that the tire is not overloaded (one tire is rated at 760 pounds at 90 psi) and it is inflated to the maximum psi rating of 90 pound per square inch, then the tire will last a long time and perform well for you.

I would recommend you check the sidewall of your tire to determine what the max psi is and inflate the tire to it.

It is possible to use a tubeless tire on a wheel designed for tube tires without a tube. The wheel has to be a one-piece wheel that has a hole for a valve stem and a flap to help seal the tire to the wheel.

  • Lug Nut Torque to Use with 15 inch Trailer Wheel
    90-120 ft lbs of torque is probably about right for your 15 inch trailer rims. If you check out the lug nut torque chart that I attached you will see that nearly all of the torque specs are that and higher. You'll need to know the diameter of the wheel stud and the type of metal that the wheel is made from. Most likely what you have is steel and a 1/2 inch diameter stud so the correct torque rating would be 90-120 ft lbs.
