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.


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


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.


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.


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. +


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.


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.

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!!
Terry M - 05/22/2021


Poor description. Any other company that sells wheel and tire combos ships them assembled and filled with air. I was disapponted when these arrived not even mounted on the rims. Now I need to pay a tire shop to mount them.

I see that you have this tire along with rim part # AM20522
Dexstar Steel Spoke Trailer Wheel - 15" x 6" Rim - 5 on 4-1/2 - White Powder Coat
. We do have the tire with rim combination in part # TA47FR
Contender ST225/75R15 Radial Trailer Tire w/ 15" White Mod Wheel - 5 on 4-1/2 - Load Range E
. The bolt pattern is the same as a 5 on a 4 and one half however it is a modular wheel versus a spoke design wheel.
-- Etrailer Expert Jenny N - 12/02/2021


Tires have been great. Super sturdy sidewalls. Reliable tires. They wont come apart or explode like some unmentioned brands.


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
mike B - 04/02/2018


Placed the order and the delivery was very quick. Very happy with the service. Would recommend


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


Ordering Easy...Shipping Fast ... Tires are Good for our fleet of trailers and priced right...


Haven't put the tires on yes (just came in today), but I do have to say how happy I am with customer service. I ordered non-radial tires by mistake and realized my issue after I received word that the tires were being shipped. I quickly asked if radial tires can be swapped for the tires being shipped. The radial tires showed up - thank you!


Its been a year all is well so far.


Have not put a lot of miles on them yet but I have confidence in them


Great tires on my 28' enclosed trailer. They have light rolling resistance, wear well and seem to have good traction in all weather conditions. I bought four to replace my originals after road debris caused two punctures on my last trip.


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.
Malcolm - 09/02/2020


Well shipping was great except I only received 3 of the 4 tires i ordered. Not sure what happened, but i need the 4th tire going to be traveling in about ten days.


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.

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.
Robert A - 01/18/2020


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
Scott - 07/01/2020


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
gearhead 7 - 10/11/2020


I found a bad tire during my pretrip maintenance and 4 day shipping was exactly what I needed to get back up and running. Thanks Etrailer for coming through in the clutch.


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.

  • 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...

  • Load Range E Trailer Tire Size ST225/75R15 Recommendaiton
    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. Any local tire shop near you would have no problem at all installing this tire. We do not have installers. I attached a review video for this tire for you to check out as well.

  • What Tire Pressure Does Trailer Tire Need, PSI Listed on Tire or on Trailer Frame
    With tire pressure you have to go by the pressure rating that's listed on the tire sidewall. Most likely your old tires were of a different size or Load Range and that's where the 55 psi rating came from. If you don't inflate your trailer tires to the max figure listed on the sidewall they won't have the full capacity and they most likely will get hot and fail as well.

  • Why are New Tires on Boat Trailer Evenly Worn on the Outside Edges of the Tread
    I spoke with our resident tire expert about the wear on your tires and the only known cause for the treads to be worn evenly on the outside edges as you described is an under-inflated tire. I know you stated that you always keep them inflated to their max psi, but I recommend verifying the maximum psi of your tire as listed on the tire sidewall. Since they are newer tires, it's possible that they have a different psi rating than the previous tires on your boat trailer. I have also included...

  • 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...

  • Recommended Replacement Special Trailer Tires for 1964 Vintage Travel Trailer
    First things first: cool trailer. What I suggest you do is reply back to me with your trailer's current tire size. This will be noted on the tire's outer sidewall. Also noted on the tire sidewall will be the weight Load Range the tire is rated for. This may appear as "LR B" or "LR C" for example. Any given trailer tire size could be offered in several different weight load ranges and so you'll want to select tires of the appropriate size, of course, but also with the load range rating...

  • What is the Diameter of a ST225/75R15 Tire in Centimeters

  • 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...

  • 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...

  • Can a 225/75R15 Trailer Tire Replace a 205/75R15 Trailer Tire
    You should have no problem installing a 225/75R15 on a rim that previously had a 205/75R15, but you should note that 205 is designed to fit 5 to 6-1/2 inch wide rims and the 225 is designed to fit 6 to 7 inch wide rims. You might verify your current rim size first. Also, the 225 will be almost an 1-1/2 inches taller than your previous tire. You'll want to make sure you have the clearance. If all that checks out the tire I would recommend is the # AM10303. This is a Load Range E tire.

  • Do Trailer Tires Have Speed Ratings
    Speed is a huge issue with trailer tires actually. Unless otherwise noted trailer tires are rated as 65 miles per hour as their max speed. Exceeding the speed rating will cause the tire to heat up and fail easier. We do have a couple brands that have higher speed ratings. The Taskmaster radials like the part # C22515D which is an ST225/75R15 like you mentioned has a speed rating of 81 mph. The Lionshead part # LHWL304 has a speed rating of 75 mph and has a 2 year roadside assistance program...

  • Can Tire Pressure Be Lowered When Going with a Higher Load Range Trailer Tire
    Special trailer tires should be inflated to their maximum air pressure. The value for the maximum air pressure should be listed along with the value for the maximum load on the tire's sidewall. These values will usually designate the maximum load at a maximum psi. For example, if the tire is rated at 1,610 lbs maximum at 65 psi, the tire can carry 1,610 lbs of weight if the air pressure is at the maximum of 65 psi. At the maximum air pressure, the tires will perform and wear best, and get...

  • Speed Rating of Karrier ST225/75R15 Radial Trailer Tire # AM10303
    The Karrier ST225/75R15 Radial Trailer Tire, # AM10303, is going to be rated for speeds up to 65 miles per hour. This is going to be the same for all trailer tires unless otherwise stated. Exceeding the 65 mph limit can cause heat to build up in the tire and cause it to fail.

  • Can a Trailer Tire be Ran at Lower PSI than Max Pressure Rating
    One of the great things about the Goodyear Endurance trailer tires like the # 724861519 you referenced is that its one of few trailer tires that can be ran at a lower psi than its max rating. So what this allows is you to run your Load Range D tire at it's max psi and then lower the psi of the Endurance to match so that you have equal pressure in both.

  • 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....

    All trailer tires like the Karrier ST225/75R15 Radial Trailer Tire # AM10303 that you referenced are intended for use on pavement so they have tread patterns that are going to perform the best in highway applications. Since the tires are on idler axles (not powered) they don't really need an aggressive tread pattern so this tire would do just as well as any other tire out there in the situations you mentioned.

    Although we don't have any tires in the 235/75R15 size we do have the 225/75R15 size. If you are only looking for tires then I recommend the Karrier # 724857519 which has a load rating E (2,830 lbs at 80 psi) and a speed rating of 81 mph. This is the best tire that we have to offer in this size. If the inside and outside treads were wearing prematurely on the tires on both side of your trailer then that is an indicator that you didn't have the tires inflated enough. To avoid this you want...

  • Can I Replace Trailer Tires with Light Duty Truck Tires
    Thank you for trusting us at the beginning stages of your research! Trailer tires actually have a different design than passenger tires (like the light duty tires you are talking about) so you always want to stick with trailer tires for a trailer. The sidewall is more stiff because they don't have to help with a comfortable ride. This means that they are much better suited to handle the heavier trailer weights and they do a better job as dissipating heat when under a heavy load than passenger...

  • What is the Difference Between Trailer and Passenger Vehicle Radial Tires
    The difference between trailer and passenger vehicle tires is that trailer tires, like the Karrier ST225/75R15 Radial Trailer Tire # AM10303, have a stiffer sidewall which helps them to accommodate the heavy trailer loads. Passenger vehicle tires have more flex in the sidewall to help give you a smoother ride.

  • Replacing 205/75-15 Trailer Tires with 225/75-15 Trailer Tires
    The 225/75-15 tires you are wanting to install are only just slightly larger than the 205/75-15 tires you have now so they can be swapped out rather easily. They will work just fine with the wheels you have now as well so you shouldn't have any worries here. I recommend the Karrier ST225/75R15 Radial Trailer Tire part # AM10303. The tires should be filled to 80 psi and will give you a total weight capacity of 5,660 lbs. They are rated for 81 mph.
