Radial Tires vs. Bias Tires

Radial tire vs bias tire graphic

Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.

Unfortunately these only lasted 2 years and less than 8,000 miles before the belts "slipped" and the tires ballooned and got tall and round. I pull a 10k GVWR two-axle toy hauler weighed at 7800 lbs on the axles. These survived two 2600 mile trips and a few shorter trips at up to 65 mph. 3 of 4 tires ballooned and I replaced them before they blew. I filed a Kenda warranty claim and they denied that they could see anything wrong in the pictures. etrailer said Kenda handles warranty claims for these.

Kenda does indeed hold a 5-year limited warranty on these tires. It seems that our customer service department is in the process of getting that warranty claim issued for you.


Great tires. I have them on my 42' enclosed 3 axel. Packed everything we own, 32,300 lbs and went from upstate western NY to SC, pulling it with my Ram 2500 5.7 Hemi, totally overloaded and they pulled nice ! Then the trailer sat in storage, still loaded and didn't lose any air in 8 most. Would buy again for sure.


My son had good things to say about these tires and I wanted to try a different brand after having some issues with the ones I was using.
I checked with my local guy and he couldn't get these.

Found them on etrailer and they had the lowest prices with free shipping. Problem was I needed them for the weekend and you know how shipping goes, they are never there when they say they will be.

Well I spent $25 extra to get them here in three days. I could not believe it, they were here in three days! Must have been that two hours after I ordered them I already had a tracking number, that must have helped!

I got them mounted up with my new valve stems and they are looking good.


These tires are obviously more sturdy that the set of 4 that I bought on that major e-commerce website. When two of them started coming apart, I bought two more. When the 3rd one failed, I knew I would have to spend a little extra money to get a good tire. I've only run them 41.3 miles so far, so the verdict is still out. I expect many thousands of miles from these. But the other cheap tires only gave me a couple of thousand miles--an expensive lesson.


Other dealers claim to have the parts I need....l placed the order then 4 business days I get an email saying not available for 3 to 4 weeks...that's not what your website said. Then I have to wait 5 more business days to get my money back. Yes their prices was better but I contacted you guys at etrailer and gave you my list of parts needed. 5 days later UPS is knocking on my door and unloading my parts. I could never be more happier at this moment....Thanks etrailer
My new found friends.


Really a quality tire very fast shipping looks good on my car trailer!!


I tried unsucessfully to order tires from but their web site would not process my order over the weekend so on monday i tried all day to talk to anybody to help me out but never got thru so tuesday i decided that if i cant even get thru to the sales dept why would i want to purchase there so i looked around and etrailer had the exact tires i wanted and a 110% low price garrantee so i called to get assistance and Judy answered and got me all hooked up i had to purchase them full price then she credited my account within 15 mins they were shipped that day and they were at my house thursday when i got home - Awesome, they came in individual boxes and when i opened them up and checked it out they were all the correct size and load rating and the build date on all the tires were 4516 which means they were built in the 45th week of 2016 which makes them about 3 and a half months old i am very pleased with Judy and all her help and etrailer for the super fast shipping i will be shopping here in the future

got about 5k miles on them now and they all are performing as they should


We have a 5th wheel & we normally travel about 3 months a year. However, this year we are traveling 6 months and we will be home by the end of April. So far we have traveled in 27 states and about 14,000 miles. I can't say enough about how good these tires have performed. Especially, since many of the roads and highways we have traveled are very rough. The tires are performing greatly, no flats, very good thread wear, (even on all four), no noise, no problems. I love them. +


I purchased these tires a year ago and have used them to cross the country… Thousands of miles and they are looking great. I knew what kind of tire I wanted from the get-go and I’m glad I went with Karrier.


Best transaction I’ve had online. They had the tires I needed in stock and received them in less than three days. This is my second order from and will not be the last.. The tires came in individual boxes and were Not damaged at all. I highly recommend doing business with this company.

Terry M.


The tires are doing great on my travel trailer, in two weeks we will be taking it out for another 2000 mile trip, Great tires!!


Quick Service and free shipping. I was very pleased with the overall experience


The service from etrailer for the Kenda/Karrier ST225/75Rx15 trailer tires was excellent. They shipped and arrived as promised. The price point was good as well as compared to others who sell these tires. These Load Range E will be used on my 25' enclosed car hauler trailer, replacing the factory tires that lasted only 18 months. The trailer is headed to Florida and back, from Pennsylvania, in March, so they will get a good workout.

Robert A.


The tires have preformed well. They have made several long trips with heavy weight with no problems. Wear has been slight after approximately 6000 miles. I will buy another set for my smaller trailer when they are needed.


good tires have on heavy toy hauler when we changed form original tires to these you could feel the lessened rolling resistance , trailer moved much easier. Have gone a several long distance trips with these 2,000 miles plus with these towing a loaded heavy trailer . They handle weight well and have no bad traits. Picked up a spare tire from etrailer going on another trip a spare was original 12 yrs old. Hopefully i never use bought load range E and have them set at max inflation pressure.



Tires still working and wearing well have gone on 2 trips 6,000 miles total. Great tire at a great price


I needed a tire for a spare and a co-worker told me about your company. Lots of choices and with free shipping, couldn’t go wrong ordering from you. Priced competitively, arrived boxed(!), nice and clean. Will definitely use the company again for any trailer related items needed in the future.



Thankfully, it’s a spare and haven’t had to use it! Holding air and looks as new with no miles.


This is the second tire I have purchased. The first tire is holding up just great. So I had a need for a second one and purchased another one.


Going to have them mounted and balanced tomorrow, so far so good. Taking a trip to Cape Hatteras in a couple of weeks. It will be a good test! My rating is a 5 as of now Great service and product and as always great customer service !


seems like a good tire, good price, high load rating and fast shipping , but I wont really know till the tire is used for a while



still keeps air and works fine


Needed a new set to replace an old set of continentals on my triple axle airstream. I could immediately tell the difference between the two sets in the Kenda's were much smoother and not nearly as bouncy. MPGs went up from 12.5 to 14. Definitely recommend these and would buy again.


They seem to pull easier and ride better on my camper. I really like them.


Needed a spare tire for my phoenix trailer. Trailer had I'm stock correct size and load rating.


Tires were shipped very fast and arrived in great shape. Took them right to a shop for mounting and just returned from a trip. Very happy!

George W.


Still look new! Tires have been on a year and are wearing well. Tire pressure stays consistent.


Great service and communication!!


Kenda Karrier Load Star tires were highly recommended by other trailer owners to me. These tires are load rated E, the best load tire for an 15" tire, and they are speed rated M, which I believe is 81 MPH. As far as I know, only the Goodyear Endurance tire is speed rated N, which comes at a higher cost. It is too early to tell you just how good they are, yet I have high confidence in them.


What a great experience working with etrailer. The sales team were super responsive and helpful. The products (tires and rims) are top-notch and can't be beat with their price matching. I'm definitely a etrailer fan now for all my trailer needs.


I went on a trip for 2 weeks and 4480 towing with my Airstream and these tires handled well. No problems with them at all. When not in use the trailer is parked in a garage, so not subject to any elements. The tires held well, no air pressure loss and did as expected for a trailer tire

  • Determining the Weight Capacity of Trailer Tires
    The weight capacity listed for a trailer tire is the capacity of just that tire. So for example the Karrier ST225/75R15 Radial Trailer Tire - Load Range E # AM10303 has a maximum load capacity of 2,830 lbs at 80 psi. If you had four of those tires on your tandem axle boat trailer, the tires would carry a total weight capacity of 2,830 lbs each for a combined tire weight capacity of 11,320 lbs. Keep in mind that the weight capacity of the tires will not supersede the weight capacity of your...

  • Does Cold Tire psi Need to be Changed on Hot Days
    When someone is referring to a tire being cold, they mean when it is not being used on the road - when it has been sitting still overnight and has cooled down. The 80 psi rating on your tire, like the Kenda Karrier # AM10303, has been tested extensively by the manufacturers before releasing them to the public. This means testing them on hot days. Since this is the case you will want to inflate the tire to the max psi rating that the manufacturer has stated. Anything more or less will change...

  • Troubleshooting Outside of Front Right Tire Cupping
    Cupping is caused by bouncing and generally the issue is you are out of alignment. It may look fine but I do recommend having your toy hauler taken to a trailer repair shop and having it checked out thoroughly to be on the safe side. Tires will also wear on the outside due to being under-inflated so they need to be inflated to max psi, rated for the proper load you are carrying and also balanced. There are a number of potential issues so as I stated, a trailer shop who specializes in...

  • Why Would a Trailer Tire Fail
    Tire failure is usually caused by a few things. It can be from overloading the trailer, improper tire inflation, and/or exceeding the speed rating for the tire. You should verify that the tire capacity you have for you trailer is adequate for how much your trailer weighs. The pressure ran in the tires makes a big difference in longevity too. ST tires should be ran with the full pressure rating stated on the side of the tire, for full load capacity and longevity of the tire. If lower pressures...

  • Replacement ST225/75R15 Tires for 2016 Keystone Ultra Lite Grand Touring Trailer
    For your 2016 Keystone Ultra Lite Grand Touring Trailer I highly recommend switching to the radial Kenda Karrier ST225/75R15 Tire - Load Range E # AM10303 that you mentioned for a couple of reasons. First, it is always a good idea to have a healthy safety margin between the combined load rating of your tires and the loaded weight of the trailer. This allows the tires to run a bit cooler (excessive heat is the most common cause for tire failure) since they are constantly supporting less...

  • Availability of 205/75-15 Tire with Load Range E
    The reason you have not been able to find a 205/75-15 tire with a load range of E is because they do not have one. For this tire size, D is going to be the highest load range which will have a capacity of 2,150 lbs at 65 psi. The load range varies between tire sizes, so you do not necessarily need an E if you upgrade your tires, but it also won't hurt anything. Assuming you have the correct rim width, you should be able to add the Karrier ST225/75R15 Radial Trailer Tire - Load Range E...

  • Recommendation for Replacing 7.00-15 Tires on Trailer
    As you mentioned, the 225/75-15 tire size is the next closest size we have available to your existing 7.00-15 tires. As you also referenced, the thing you will need to look at is the size of your current wheels, as the 7.00-15 tire will typically fit a 15 x 5-1/2 inch wheel. A 225/75-15 tire like the Kenda # AM10303 is compatible with 15 inch diameter wheels that have a width of 6, 6-1/2 or 7 inches. They simply will not fit onto a wheel that has a width of less than 6 inches so I cannot...

    For a Load Range E trailer tire in the ST225/75R15 tire size you are looking for we have the part # AM10303. This is a radial tire that has a capacity of 2,830 lbs at 80 psi.

  • What PSI Should Trailer Tire Size ST225/75R15 be Inflated At
    A trailer tire should always be inflated to its maximum psi when the tire is cold. The maximum psi for a specific tire will be listed on the tire wall and may be different from manufacturer to manufacturer. Even on the same size tire. Occasionally you'll even see different recommendations on the same size with the same manufacturer. If a trailer tire is over or under inflated the life and capacity of the tire can be compromised.

  • Proper Tire Weight Rating For A 2011 Keystone Laredo
    The trailer manufacturer determines what size tire and load range is adequate for the trailer. Personally, when looking for trailer tires, I try to find a tire that meets or exceeds the weight capacity of my axle in the same size tire used by the manufacturer. This allows for a small safety net considering the axles do not hold the entire gross trailer weight(GTW). On 5th wheel applications, about 20% of the weight is resting on the rear axle of the tow vehicle if loaded properly. The...

  • Should Trailer Tire PSI Match Sticker on Trailer or Number on Tire Sidewall
    Trailer tires should always be inflated to their maximum psi as listed on the sidewall of the tire itself. This means you should inflate the new tires on your trailer to the 80 psi that you mentioned in your question. The sticker on the trailer refers to the psi that was listed on the stock tires. It sounds like you replaced the factory tires with units that have a higher load range capacity, which explains the jump in maximum psi. I have attached a great article on trailer tires that...

    We have a 10 ply trailer tire in the size 225/75R15 with the part # AM10303 but this is a trailer tire which you'd need to use on a trailer. You shouldn't use truck tires on a trailer as they are not rated for the vertical load that trailers see.

  • Are Bias Ply and Radial Ply Tires Compatible with Each Other on Trailer
    The ST225/75D15 tires on your trailer indicate that they are bias ply tires, different than the ST225/75R15 units also on your trailer, which are radial ply tires. I do not recommend maintaining this existing mix between the two tire types, as they will not track the same which can result in uneven tire wear down the line. I recommend replacing the two bias ply tires on your trailer with radials so that all of them match. When choosing replacement tires, you will also want to make sure...

  • Proper Tire Pressure on Kenda Karrier ST 225/75 R15 Load Range E Tire
    The 225/75-15 Kenda Karriers with a Load Range of E are part # AM10303. I went out to our warehouse and verified the tire's maximum psi is 80 and has a maximum weight capacity of 2,830 pounds. Special traier (ST) tires should always be inflated to the maximum air pressure. If it's inflated to a higher or lower psi the maximum capacity of the tire is unknown because it won't perform as it's designed which will cause uneven wear, excessive heat, and eventually failure.

  • Mixing Load Range E Tires w/ Existing Load Range D Tires on Triple Axle Trailer
    I wouldn't recommend doing so, especially given the amount of weight your dealing with on a triple axle trailer. If you're referring to the ST225/75-15 tire size, a load range D should be kept inflated to its maximum pressure of 65 psi, while the load range E should be kept inflated to 80 psi. It's easy to forget that not all of the tires need the same air pressure. Having some of the tires inflated incorrectly can lead to an unsafe situation. At the very least, each axle should have two...

  • How Much Should Travel Trailer Tires be Inflated if it has 2 Different Load Ranges
    The trailer tires, all of them, will need to be inflated to the maximum psi indicated on the tires. If the shop reused the same valve stems though it could be too much psi and you would need to also replace the valve stems if the new tires start leaking air. Ideally you would want all the tires on the trailer to be the same size, load range, and construction type. Otherwise it can affect tracking and you will have uneven wear since the ply ratings are different among different load ranges....

    Most trailer tires aren't rated for 80 mph plus speeds. I'd be willing to bet that your tires are failing from exceeding the speed rating or they are underinflated. The Kenda tire part # AM10303 has the highest trailer tire speed rating we have in your size of 215/75-15 which is 81 MPH. Most trailer tires can only do 65 mph.

The 7.00-15LT tires that you have on your 1987 Prowler Regal 5th wheel are light truck tires which you will not want to use on a trailer as they are meant to be used on a passenger vehicle and have a slightly different construction.
