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.

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.


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.


They have been great, much better than the load range c tires that exploded.


Very fast shipping. The tires are excellent quality and big upgrade from the load range B bias ply I had previously.


Excellent as always. This particular tire size and Load Range is superior to garbage tires sold at Walmart.


Fast, speedy delivery of a set of tires. Customer service staff is outstanding with answers to questions within minutes. Thank you all.


Exactly what I was looking for to match the other tire. Hard to find these tires in a "D" load rating and in radial design.
My trailer torsion suspension failed on one side and caused the old tire to rub on the fender. The old tire is not holding air now so I'm just replacing the old tire with a matching unit.


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.


these tires hold up very well and give years of service. If you are mounting them yourself, they're very easy to seal on the rims.


Perfect fit to replace boat trailer tire they don’t make anymore. Arrived on time great looking tire very happy I purchased them


Great tire, replaced old dry rotted tire perfectly.Trailer rides smoothly.


Outstanding customer service and very fast delivery of the items a bought. Thanks again etrailer for great service


This was my first experience purchasing new trailer for my RV trailer and my first experience with etrailer. James R assisted me in ordering the right tires and the tires were shipped THE SAME DAY. I would highly recommend etrailer and I will order from them in the future.


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


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.


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.


Great response and fast shipping


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!


tires look very good.
Will have them
mounted thursday.


Fast shipping, tires shipped in boxes which is safer.


Did well for our 5000 mile trip.


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.

Larry E.


Very good no problem at all.


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.


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.


Well, the product is very good. Happy with the initial inspection. Can give more after install. However, the experience with Tammy was AAA+. Info on your website AAA+. I am very happy to work with folks who know their trade and help customers understand. I am confident recommending to others, including family. I will be back.

  • Do Karrier ST175/80R13 Radial Trailer Tires Work Well on a Tow Dolly
    Definitely; radial trailer tires will work superbly on a tow dolly and are the best option for highway use because they run cooler than other tires and flex more. This allows the tire to have the most overall contact with the road, giving you better road traction. A dolly is, in essence, a trailer, so trailer tires will work wonderfully, including the Karrier you asked about: - Karrier ST175/80R13 Radial Trailer Tire # AM10210 The # AM10210 fit 13 inch wheels and have a speed rating of...

  • Tire Options on Utility Trailer With P185/80R13 Tire Size
    First, I would try to find a identification tag on the trailer to determine the weight capacity of the trailer and if it list a recommended tire size. This would help you determine the capacity of the tire you will need. The P185/80R13 size is a passenger tire size. A trailer tire will always have a ST designation before the first number to let you know it is a special trailer design tire. A trailer tire will have stronger sidewalls and normally a higher load capacity compared to a passenger...

  • Can Tire Sizes on a Trailer Be Mixed
    You'll want to make sure that all the tires on a trailer are the same size, load rating and construction (bias ply versus radial). If you're wanting to match an existing tire, I'd be happy to make a recommendation if you can reply with the exact tire size and load rating and whether the tire is a bias ply or a radial. This information can be found on the tire's sidewall. I'll link to our series of trailer wheel and tire articles which I hope you'll find informative.

  • How to Measure for Bolt Pattern on a Trailer Wheel with 4.80-12 Tires and 5 Bolt Wheels
    Measuring for bolt pattern of a wheel is easy. I have included a link to an FAQ article that explains how to do it. Since you have a 4.80-12 and 5 bolts you probably have a 5 on 4-1/2 bolt pattern. I have also including links to wheel and tire combos and a link to just wheels in this size and bolt pattern.

  • Should Wheels be Replaced with the Tires on a 10 Year Old Coleman Pop Up Camper
    If the wheels on your trailer are rusting or appear to be bent or otherwise damaged then it will be time to replace them. If they appear fine and are not rusty then you do not have to replace them. The benefit of getting a tire and wheel combo with the tire already mounted is that you do not have to worry about getting them mounted or balanced. A quick note on balancing. Trailer tires do not have to be balanced. You could have them balanced if you want but the problem is that most tire...

  • Is it Okay to Have Different Size Tires on a Trailer
    Having different size tires on your trailer can cause a couple of different issues. The first one being that they have different weight capacities. Your 4.8-12 ranges from 785 lbs at 60 psi to 990 lbs at 90 psi whereas your 5.3-12 ranges from 840 lbs at 55 psi to 1250 lbs at 105 psi. An important point of consideration is when using two different size tires, the load has to be no more than the capacity of the lowest rated tire. With this substantial difference with both weight capacities...

  • How to Pick Out Trailer Tire Size for Boat Trailer
    I would recommend sticking with the same size you currently have on your 1988 Escort boat trailer as we do not have a way to look up what the trailer was built with.

I also attached a few trailer tire FAQs for you to check out. Once you know what size you need check out the link I attached that will take you to a page that has...

  • When Should Trailer Tires be Inflated to Their Max PSI Rating
    When inflating trailer tires you want to inflate them to the max PSI rating when they are cold. So your tires should be inflated to 65 when cold and you'll be set. You wouldn't have to worry about heat causing excess pressure in the tires unless you were exceeding the speed rating or weight rating. I attached a help article on trailer tires for you to check out as well.

  • Trailer Tire Needed that Fits a 13 Wheel and Has a High Speed Rating
    For a trailer tire that fits a 13" wheel I recommend the Kenda Karrier # AM10210. This is a ST175/80R13 Radial Trailer Tire that has a load range of D (1,610 lbs at 65 psi) and a speed rating of M (81 mph). This tire fits 13" x 4-1/2", 13" x 5" and 13" x 5-1/2" size wheels. Most trailer tires have a speed rating that only reaches 65 mph. The 81 mph speed rating is the highest for this tire size. Since you need 2 of these per axle that puts the load rating at 3,220 lbs which is more than...

  • 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...

  • Recommended Replacement Radial Tires For Trailer When Bias Tires Are Wearing Unevenly
    There can be a couple reasons why your tires are wearing on the outside edge. The first may be that you have the tires on a trailer that has a large capacity and you are not carrying much weight. Since axles have a bow and flex a bit when a load is placed on the suspension, all of the tire may not be coming in contact with the pavement evenly. Another possible reason for the uneven wear is the axle has been turned over and used with the bow going the wrong way. Another possibility...

  • 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.

  • Will Higher Load Range Trailer Tires Change Trailer Ride Quality
    The metric equivalent size for an A78x13ST original trailer tire is the ST175/80-13 size you referenced. Changing to a higher Load Range tire will not really affect your ride quality very much. But what this will do is help to prevent excess heat in the tires since they will tend to remain cooler if they are used below their rated capacity. A tire that has to carry 90-percent of its rated load capacity will get warmer than one that carries only 70-percent of its maximum rated load. Since...

    The Kenda 175/80-13 size tire you asked about, part # AM10210, actually has a maximum speed rating of 81 mph. Traditionally pretty much all trailer tires had a max rating of 65 mph but recently that's changing. Tire manufacturers have been testing and rating their tires for higher speeds so a lot fo tires that had only been rated up to 65 mph are increasing to a higher rating.

    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.

  • At What Age Should Trailer Tires be Replaced
    Trailer tires should be replaced about every 6 or 7 years, even if the tread is still in good shape. As tires age, they can crack and dry rot.

If you need a 175/80R13 then the part # AM10210 would be a great option.
