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.

Bought 3 of these to replace the original 2 tires + spare on my 2014 single axle travel trailer. Tires perform very well, no problems.


I bought 2 wheels and 3 tires to replace some old tires on my double PWC trailer. Put both new wheels on yesterday and mounted the extra on an old wheel for a spare. Mounted this to the trailer using spare tire carrier and everything worked out great. The tires and wheels look great and the spare mounted without any problems to the trailer.


I bought this tire to replace the spare on my trailer of 18 yrs. Also bought the wheels with the same tires, now my trailer looks like a newer model. THANKS ETRAILER!


I have had excellent results with these tires (3rd purchase). Etrailer also does a great job! Communication is excellent!


Just what I was after. Shipping was fast and tires arrived in individual boxes that were in perfect shape when they got here. Thanks again for another successful purchase.

The tires are working out for me as expected. Great tires for my boat trailer.
Duane - 04/26/2021


These worked well for my application. 3500 pound Dexter, boat trailer. I ran them around town and to the lake a few times, then decided to get another as a spare. I've made many purchases from etrailer. etrailer's service is unmatched. I typically receive my order in 2-3 days, which is pretty incredible.


I recieved the trailer tires really fast. They have a good tread design and when mounted look great. I installed them on a very small travel trailer which came out with a load range C. These have a load range D which should be an improvement due to a little more pressure and carring capacity. I am very pleased with the delivery time and looks of the tires.


tires seem to be heavy duty. I am glad that I ordered from you. the free shipping was a plus also. THANKS


They are definitely different from the bias ply Tire. I will see how they will ride and last. They look more like a car tire.


Looks nice but I can’t give an honest review because it’s for a spare wheel for my trailer. I’ll update this review if I’m unfortunately forced to use it. I will say that I choose a radial instead if a bias ply because the supposedly trac better.


I purchased two of these tires for my boat trailer 5 years ago. They had maybe 10-12k miles on them. Last fall I had one of the tires go bad - the tire cords failed causing uneven wear. It didn't blow out but I was perhaps lucky. Purchased a replacement - same tire. Last month I had a similar cord failure with the other old tire. After that problem was going to purchase 2 new name brand tires but couldn't find any D load rating tires in the 175/80R13 tires. Decided to just buy another Karrier tire. When my mechanic changed out the second tire he said the inside of this one was far worse than the first failure. I was running the tires with 55 psi of air with a max listed pressure of 65 psi. Maybe that was a factor so now running the tires at 60 psi and plan on changing them after 3 years. Not real comfortable with these tires but hopefully I can get 3 years out of them without a failure.


We have used these tires for 8 years (3 sets) for our heavier than normal hard side pop-up camper trailer. Most of our miles are on gravel roads and these tires have stood the test.

etrailer has always been top notch to work with and ship on time.


Great service!! Good products!


The team at etrailer were professional and on top of things from beginning to end!! Thank you etrailer


Ordered tires for trailer. Rec'd the freshest I've ever seen. Manufacture date was 30 week of 2017. Installed 7/19/17. Does that even add up???? 8 Ply trailer tires hopefully will minimize the tire explosions in the future.

So far so good.
Joe T - 07/23/2018


These tires were exactly what I ordered and arrived really fast, within a couple of days. I obviously can’t review the tires since I just unboxed them but I know etrailer carries quality products. I had such a good experience with my 1st purchase from them a few years ago (Tekonsha brake controller ) and they have such a good reputation with the RV forum I frequent that I felt comfortable ordering without calling them. The manufacturing date on each tire is 1421 which I am really happy with. Mid April to mid September is good! Thanks, guys!


Great price. Fast delivery. I am one the road again. Would order again.


Excellent tires!


Have to run a lot of air pressure with this tire, seems to bounce the trailer a little more when hitting bumps. Does track straight and easier to push trailer with boat back in garage.


Just returned from 2nd long road with about 3400 miles each. Also logged a few 300 mile trips. So far, holding up well. Run 50 psi. Tires are D rated. This is my 2nd set of 4(double axle). 1st set didn't quite go as far. Had sidewall failure on two of the four. Maybe bad batch. Would recommend due to steel belts and D rating. Original equip. was C rated and fiber glass belted.

Trailer tires, unlike those used on passenger vehicles, should be kept at the maximum pressure indicated on the tire sidewall, which is 70 psi in this case. Failure to keep the tires fully inflated can lead to excessive heat build-up, which is the number one cause of premature tire failure.
-- Etrailer Expert Mike L - 05/30/2019


Exactly what I ordered, that my local go to tire dealer couldn’t supply. Promptness of processing and shipping the order was top notch! Ordered on Monday, in my garage Wednesday afternoon!


Easy ordering. Fast delivery. Excellent tires. We are very pleased with these tires. It is a HUGE difference in how well and nice the trailer tows, rides, and tracks compared to the old tires! Huge peace of mind. Installed on a Fleetwood (Coleman) Sante Fe tent trailer. I would definitely purchase these tires from etrailer again.

After a year on the road, still very happy with the performance of these tires.
Don - 07/08/2018


Very fast delivery. Now have a tir

fast delivery. Now have tires with higher load rating on camper adding safety and peace of mind. Outstanding service.


The tires came before I was expecting them.
them on a pontoon boat trailer, it is a heavy boat, these tires held it up very well.
They are higher load range than what came out on it, I have found, money spent on a better tier is never money waisted.
Thank you for your help with this.

Very good no problem at all.
Larry E - 02/26/2020


Very good tire from first impression it is a heavy duty tire load range d..I had range c on and these d tires u can just tell are heavy duty should be great for pulling boat to the lake this summer....on a side note e trailer is awsome I ordered these on wendsday morning and they were delivered Friday at noon. Thanks

  • Trailer Tire Replacement for Size 6.50x13
    The 6.50 x 13 tire size is the old numeric sizing used in the 1970s. It means the tire is 6-1/2 inches wide and the height of the tire calculates to 23.4 inches. The closest tire size I have to the 6.50 x 13 tire will be the 175/80-13 size. It is 6.9 inches wide and 24.1 inches tall. You will need to check if you have enough space on your camper for a 1/2 inch wider and 3/4 inch taller tire. The tire will fit on a 4-1/2 inch to 5-1/2 inch wide wheel. For this size you would want the part...

  • Recommended Trailer Wheels and Tires to Replace Ford Truck Rims and Tires on Trailer
    It is always recommended to use the same tires and wheels on all axles of your trailer. It definitely isn't good you had Ford truck rims on your trailer so I'm glad to hear you have new tires. The wheel/rims of a truck are not a zero offset like most trailer tires, so that will change the function of your tires. I recommend upgrading your trailer wheels to be zero offset wheels and make sure you have all 4 matching. This will reduce road wear and keep the friction that is caused by...

  • Recommended Radial Tires for Boat Trailer in Southern California Desert
    Radial tires will do better with high ambient temps and heat from road friction which all tires have. I recommend replacing your tires with the Karrier ST175/80R13 Radial Trailer Tire - Load Range D # AM10210. These tires will be 7 inches wide and 24.1 inches. You will want to inflate your tires to their max psi prior to your trip to give you the best performance. These tires have a maximum speed of 81 mph.

  • What Load Range Tire for Size B78-13ST for Camper with GVWR of 3,070 lb
    Thanks for the picture from your trailer. From that I can tell you need a tire setup in the size B78-13ST (modern size 175/80-13) and you need to have the weight capacity high enough for a total weight of 3,070 lbs. So based on that you'd need a Load Range D tire in this size like the # AM10210 which has a weight capacity of 1,650 lbs and is a radial.

  • Trailer Tire Recommendation for Trailer with Size A78-13

  • What Rim Widths to Trailer Tires for 13 inch Diameter Wheels Fit
    In the 13 inch trailer wheel diameter we have tire sizes that will fit rim widths between 4-1/2 and 5-1/2 inches. Like the # AM10210 which is a size ST175/80R13.

  • When Increasing Width of Trailer Tire How Much Frame to Tire Clearance is Lost
    The extra width of a wider trailer tire gets split in half since the offset of a trailer wheel is zero. So in the situation where you mentioned the extra width between two sizes being 3/4 of an inch that means you'd lose 3/8 of an inch of inner wheel well space. Ideally you have at least 1-1/2 inches of clearance between the frame rail and the sidewall of the tire.

  • Replacement Tires For Older 6.50x13 Tires
    The 6.50x13 tire size is an older sizing used in the 1970s. It means the tire is 6-1/2 inches wide and the height of the tire is 23.4 inches. The closest modern trailer tire size we carry to this is ST175/80R13 like part # AM10210. The AM10210 is 7 inches wide and 24.1 inches in diameter so it is larger than your existing tires. I recommend to replace all of the tires because you do not want to mix sizes. It will fit 13" x 4-1/2", 13" x 5" and 13" x 5-1/2" size wheels so it should fit...

  • Is it Okay to Use Trailer Spare that is Slightly Larger than Rest of Trailer Tires
    It's not ideal to have a spare that's a different size than the rest of the trailer tires. If at all possible your best option is going to be to replace that tire with the correct size. But if you are stranded on the side of the road and you have the choice of staying stranded or installing a tire that's slightly bigger to get home the obvious choice is to use that spare. You'll just need to be extra cautious as now you have a trailer that is tilted slightly. If you let me know the two...

  • Are Radial Tires More Resistant to Tread Wear Than Bias Tires
    If you do mostly highway driving then radial tires like the Karrier ST175/80R13 Trailer Tire # AM10210 will be all-around better as they have a better design to say cool at highway speeds, but radial doesn't necessarily have a better resistance to poor tread wear. Typically when then inside tread of tires is wearing out faster than the rest of the tire it means that too much load is being put on the axle and it is almost bowing down which forces your tires to sit at a weird angle.

  • Boat Trailer Wheel and Tire Replacement for Size 195/70R14
    The size your trailer has on it now is a passenger vehicle tire size so there won't be an exact replacement but the closest and best will be the size ST205/75-14 which we offer on a wheel with part # 724864519A from Goodyear. This is made in the USA, has the 5 lug pattern you need, has automotive style tread for great traction, and also comes with a great warranty.

  • What Date Code Can I Expect To Receive On the Karrier ST175/80R13 Radial Trailer Tire
    The Karrier ST175/80R13 Radial Trailer Tire part # AM10210 is a very popular tire size we offer and as trailer tires are one of our top sellers here at etrailer, we are always receiving shipments of the most up to date stock. Therefore, although I cannot provide a specific date code I can tell you that most of our tires only sit in our climate controlled warehouse at max a year after they are manufactured.

  • Can Trailer Tire Size 175/80-13 be Replaced by 185/80-13
    Yes, the 185/80-13 tire size of the # AM10210 that you referenced fits the same wheels size as the 175/80-13 that you referenced so it will fit and work great. These are radials like you want, have a higher speed rating at 81 mph, and also have the weight capacity you need too.

  • Should Trailer Tires All Have Same Load Range
    It's really not ideal to have different Load Range trailer tires installed on a trailer. Reason being the different Load Ranges require different air pressures which means the tires with the higher pressure will most likely sit a little bit taller and take more of the weight of the trailer. You really want to get all of your tires to be the same size and Load Range. I attached a link to a page that has all of the trailer tire sizes we offer as well as a help article with more trailer...

  • Can Karavan Single Axle Boat Trailer Use Tire Size 175/80R13 in Load Range D
    As long as the tire you end up using has the capacity for the weight of the trailer when it's loaded you are totally fine. Size difference would not be a problem. So if your trailer will weigh up to 2,923 lbs a Load Range D trailer tire in the size of 175/80R13 like the part # AM10210 would work well as it has a capacity of 1,650 lb per tire which would put you at a total capacity of 3,300 lb total tire capacity.

  • Replacement Trailer Tires for a 1968 Trotwood Trailer with 13 x 6 Tires
    If the tire itself fits on a 13 x 6 inch wheel then fit is going to be a problem. But to measure the width of a wheel you will take the tire off and measure from bead seat to bead seat. If that measurement is 4-1/2 to 5-1/2 inches wide then we will have some tires that will fit though the overall width may be wider than what you currently have. The closest is going to be a 175/80-13. I have linked all the tires we have in this size. They will all fit a 13 inch wheel that is 4-1/2 to 5-1/2...

  • Switching from a 5.70-8 Tire to a ST175/80R13 Tire on a Boat Trailer
    You can move to a larger tire size on your boat trailer, however, there are a few factors that you will want to take into consideration before making the switch. The first thing that you will want to keep in mind is that switching to a larger tire will not increase the weight capacity of your trailer. You will still be limited to the weight capacity of your axle. The next factor to consider is that the tires you currently have on your trailer are 5.70-8 tires. These tires mount on an...

    For best performance, it is always best to stay with the original tire size whenever possible. If the weight of the trailer plus its load will not exceed the 3220 lb capacity for two of the # AM10210 Radials (1610 lbs per tire) they would be my recommendation. The radial tires will provide superior ride quality, and will generally run cooler than a comparable bias-ply tire if not overloaded.
