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.

The tires were very good. I sold the trailer after a year so I can’t say much about longevity.

I have had these tires on my trailer for over a year. They have performed very well. Balance and treadwear have been excellent. I would buy them again.

@James We're happy to hear that your # AM1ST77 trailer tires are working well for you!


by:

Ordered the spare tire rack and galvanized wheel and tire. Great price on everything, found the load range D 13” tires at reasonable price. The short tires help me get the boat in the water even when tide is out.



by:

Shipped & received quickly. Only source I have been able to find for these tires, so appreciate having them in stock.



by:

I’ve now had two sets of these on my boat trailer(they were replaced once on warranty) they chunked and came apart each time. Both tires have the same chunking. These are barely a year old off a small aluminum boat trailer. etrailer was awesome in all aspects, the tires are just junk from manufacturer.



by:

Ordered 2 boat trailer tires, Loadstar ST175/80D13 bias 8 ply load range D, early CST on the morning of 4/09/14. I selected 5-7 day standard ground shipping at no charge. I was notified within an hour by email that the tires had shipped and that shipping was upgraded to 3-5 days at no charge to me. The tires shipped at 9:39 a.m. CST and arrived 2 days later on 4/11/14 at 11:04 a.m. CST. What more could a man ask for! I already have them mounted on my trailer and I am looking forward to seeing how they perform. I ordered the tires from e trailer because I could not find any 8 ply load range D tires locally in the size my trailer/boat called for. The price was very good also. Thank you e trailer for an excellent experience and great service. I will definitely remain a customer.

The tires have performed flawlessly and I will continue to be a customer for any future trailering needs.

needed replacement tires for my Coleman/Fleetwood tent trailer. the old ones were 14 years old, and badly worn. local tire shops carry little, or nothing for replacements, and at a $100 each. got the exact OEM name brand replacement tires from this place for a little more than half that, with free shipping. local "discount tire" mounted and balanced them for $20. these tires were date coded from January of this year, and made in Taiwan. much preferred over Chinese stuff. these are bias ply, 6 ply (8 ply rated) nylon and polyester corded tires. they appear to be very well made. the side walls of bias ply tires are much sturdier than radials, and i believe they will be durable. they were shipped fast, in a large sturdy box. could not be happier.

working great, am very happy with purchase



by:

Purchased these tires in Jan for my boat trailer. They appeared to be a little deformed which I thought would make them hard to mount. I did not plan to install them right away. After talking with tech support I was reassured they would be OK. Just got around to installing them myself and they worked out just great and they were exactly what I was looking for on my boat trailer.

After a year of running these tires I could not be happier. They have taken all of the abuse I could give them and no problems. Besides all of the short trips to the lake I have made a trip across the country to Arizona with all of the heat on the highway and still no problems.



by:

The 13" 8-ply LRD Load Star trailer tires perform very well. I get about 10K miles on a set before I replace them and I am on my third set. No flat tires yet!

The tires are performing very well. Of course, my snowmobile trailer sat all summer with four machines inside and the tires did not require any air this winter. We have put nearly 3000 miles on the tires and they show no wear so far. I find it remarkable that they have not lost any air at all. I am very pleased.



by:

PERFECT!!! Super fast shipping,excellent product,astoundingly good price and unusually excellent customer service!Had superb selection..found just what I wanted..cannot say enough good things about my experience w/etrailer.(tires are a joy compared to the set they replaced..recommended!)

These tires have performed flawlessly!Am glad I got bias plys as I do a lot of rough travel to rivers and lakes,etc These are Very Stable and yet Very streetable re:Hwy travel.Top notch!Minimal tread wear!



by:

Fast shipping. Great tires and great low price



by:

I purchased these tires for a home-made trailer that I wasn't sure about. The tires shipped very quickly and the price was great. I just drove over 400 miles with my news tires, and the tines are still on the tires. So far, these tires are fantastic and look like they will last a long time!

After a year, the tires are still in great shape. They are a good ride for the box trailer

Replacement tire works great.

These tires look good and have a high load rating-they are rated for a much higher weight than many tires on the market (all of the tires locally available were 4ply with a wimpy C load range) in this size TR175-80/13. They are mounted on a model 1285 Coachman Pop-up camper & I have had poor luck with the radial tires in this size-lots of cord separations & blowout failures. I am going to try out these Bias-Ply 8 ply tires. I just made my first short trip on them (approx. 200 miles in 98 degree weather) and they pulled smooth and straight. I like how they sit up with stiffer sidewalls than the radials they replaced. Be sure to have them mounted with brass shaft high pressure valve stems as the standard all rubber stems are not rated for the 65 psi pressure these tires need for maximum load rating-and it is always a good idea to have trailer tires balanced. It remains to be seen how they hold up over time on longer trips, thus the 4 star rating.



by:

Glad I found these at e-trailer. Local tire shop didn't have any Load Range" D", and wanted half again as much for their "C" tires, but they had no problem mounting these for me and installing them on my pop-up camper.

We've dragged that trailer all over the state - 4 weekends an a week long trip last year, and we're doing 5 weekends and two trips a week long this year. The tire still look new.



by:

Had to return one tire for being the wrong one. Right label on the wrong tire. Customer service was excellent. They righted the wrong and had me a new tire the next day. Thank you.



by:

Great products and great service. I bought a pair of the Loadstar ST175/80D13 Bias Trailer Tire - Load Range D - AM1ST77 and couldn't be happier with them and the service from Etrailer.com. I also bought a bike carrier from Etrailer and am just as pleased with that.



by:

I replaced the tires on my boat trailer with load star tires. Have went on 8 trips. 150 miles to 400 miles round trip. I tent camp so I load my boat down. Not one issue. Have great tread for next year. Great product. st175/80d13 bias trailer tire. My factory tires didn't even last for a year.



by:

I ordered two tires but I received one that was the wrong size due to being mislabeled. However, etrailer was quick and courteous in resolving the problem. Fantastic to work with and will definitely order from you again.

The tires are as good as advertised. Ive been from Atlanta to Orlando and back with these tires trailering my boat. Trailer handled beautifully.



by:

Have had good luck with Kenda Loadstar ST175/80/D13 Load range C on the rear axle of my deck boat trailer. I had 2 other brand tires on the front axle and they did keep up with the Loadstar's they failed. I bought a set of four of the Loadstar Load range D this time I mounted them up by hand with no problem's. Fast delivery and well packaged.



by:

Found etrailer while looking for some load D trailer tires. All the local dealers only had load C. Placed the order on a Monday and they arrived Thursday. Like some people have said do not be alarmed by the shape of the tire when you open the box as when you get them mounted they will be normal. Great price, great service, & free shipping . What else can a person want from a store. I will definitely be a repeat customer.



by:

Great 13” 8 ply trailer tires. Peace of mind towing my UTV from Missouri to Wyoming and back knowing the tires could handle the weight and road heat at 75 mph. Also was able to load up 2 Harleys and did a similar trip to Sturgis as well. Great tires and the price was right.



by:

I am delighted that I found etrailer.com to order the tires for my 16 foot enclosed trailer. The prices were by far less than anywhere else I searched on cyberspace for and the shipping was FREE and FAST. The tires arrived pristine and I have already installed them and they are working great. Very pleased to have done business with this top notch company.



by:

I am just blown away by the service and price at etrailer. I needed new tires for my boat trailer and shopped around at Wallmart, Bass Pro, Home Depot and a couple of other vendors. Your price and selection was superior to all, but the real kicker was that the tires arrived within two days of placing the order and at no shipping cost.



No question etrailer has superior service, selection and price.



by:

The tires look decent, but I’ve never seen tires this distorted before. The tire looks like a bowl, with the inside bead surface pushed out past where the outer bead surface would normally be. I tried throwing a 45lb plate on top of the bulging sidewall, then stood on top of it, but it will not pop back to normal. We’ll see what happens when I mount them, just think it’s gonna be tough seating the bead.

When the tires are shipped to us, theyre palletized which can compress them. Once theyre mounted on a rim, theyll pop back into place and work perfectly for you.



by:

Haven't put a lot of miles on these yet but the definetly a smoother ride than what the Pop-Up camper I bought came with. I bought new wheels at the same time as I like to know everything is straight. I noticed they didn't lose any pressure after six months in storage which is awesome. I only wish I had bought the wider tire.

  • How to Find Tire Pressure to Run in Trailer Tires
    On the sidewall of the tire there will be a max psi listed for your trailers. This is the PSI to inflate to when the tires are cold and you'll be set. They may fluctuate a bit higher as they heat but as long as they are inflated to the max psi when cold that fluctuation is totally normal. It sounds like your psi rating is 80 psi so most likely that's what you'll need.

  • Replacement ST175/80-13 Trailer Tire for a 2006 Scamp 16 Travel Trailer
    Any tire, when there is a load on it, will flatten out a little. The key with trailer tires is to always make sure they are inflated to the maximum psi rating as indicated on the tire. If the tires are holding pressure under load and they are not wearing then I would not go to new tires until needed. When you do switch staying with radials will give you the best performance but you could also use bias ply tires like # AM1ST77 if you take the trailer off the beaten path frequently. I have...

  • Can a Load Range D Tire be Used on the Same Wheel as a Load Range C Tire
    Yes, you can use load range D tires on the same wheel as a load range C tire as long as the tire sizes are the same. Even with the load range D tires, you should still not exceed the weight capacity of the axle. You mentioned that your trailer has 3,500 lb axles and your wheels are stamped with a weight capacity of 1,820 lbs. Since two wheels would exceed the weight capacity of the axle, you will want to use the axle capacity as the limiting factor as long as the new tires are rated higher...

  • Will 215/75R14 Tire Tube Fit a ST215/75D14 Tire
    The size difference between a 215/75R14 tire and a ST215/75D14 tire is very minimal so the tube for the 215/75R14 tire would also fit the ST215/75D14 tire. Please keep in mind that all of our trailer tires (ST) are tubeless and a tube should not be used. Using a tube will 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...

  • Trailer Tires to Replace P165/80-13 Tires on a 1963 Metzendorf Travel Trailer
    Any time you see a P in front of the size that means that the tire is a passenger vehicle tire and should not be used on a trailer. The closest trailer tire size to what you have now is an ST175/80-13. I have included a link to all of the tires we have in that size. If you know the gross trailer weight capacity I can make a specific load range recommendation.

  • Do Goodyear Endurance Trailer Tires Need to be Inflated to Max PSI of 80
    Trailer tires have to be inflated to their max psi rating at all times to ensure that you get the full capacity out of them, but also because failure to do so causes flex on the sidewall which will heat the tires up too much and potentially cause failure. That said, I am not totally sure which Goodyear Endurance tire you are referring to but I was able to attach a link to a page to all of the Load Range E tires from Goodyear that have an 80 psi max rating.

  • How to Determine How Much Pressure Should be in Trailer Tires
    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...

    Terry brand trailers ceased operations after the 2009 model year, so unfortunately it's not possible to contact the manufacturer. I was unable to find anything online regarding the original tire size, but the manufacturer typically put that information on a sticker along with the VIN and the GVWR. This sticker is typically placed either in one of the storage compartments that are accessible from the exterior of the trailer or on the inside of one of the kitchen or storage cabinet doors...

  • Recommended Tire Pressure For Tires On 1997 Dutchmen Duck 1205 Pop Up Camper
    How much air in the tires depends on what type of tires you have on your trailer. Normally, tires have a psi rating embossed on the outerwall and this air pressure is the level you should keep in them at all times. The air pressure being kept at the maximum level is crucial to maintaining load capacity and overall safety. For example, if you have a tire like the Loadstar ST175/80D13 Item # AM1ST77 then your tire would need to be at 65 psi so that it can carry its maximum load and be...

  • How do You Know How Much to Inflate a 10 Ply Rated Tire on a 1/2 Ton Truck
    On a passenger vehicle, you would inflate the tire according to what the sticker says in the door jamb or in the owners manual of the vehicle. The pressure is chosen by the vehicle manufacturer for the best ride quality given the weight and design of the vehicle. Often times different air pressures are used for different scenarios on any given vehicle such as when towing or carrying heavy loads. This is different from trailers that require the maximum psi indicated on the tire. This is...

  • What Do The Letters Mean in the ST205/75D15 C Tire Size on My Camping Trailer
    On a trailer tire labeled ST205/75D15 C, the ST stands for Special Trailer which means it is designed for use on boat and utility trailers. The 205 is the section width of the tire in millimeters. The 75 is the aspect ratio (or section height). It means the section height of the tire is 75% of the 205 mm section width. The D is the designation for the internal construction of the tire. The D stands for diagonal or bias ply construction. That means the tire body plies inside the tire will...

  • Can Tire Load Ranges be Mixed Between Spare and Rest of Trailer
    It's not ideal to mix Load Ranges since they will require different air pressure in the tire. In an emergency situation though you'd be fine to get home. In a perfect world the spare would have the same Load Range as the rest of the trailer.

  • Do My Boat Trailer Tires Have Enough Capacity For 1900 Lb Boat
    The Kenda Loadstar ST175/80D13 tires part # AM1ST77 that I believe you are referring to have a 1,610 lb rating per tire. Since you have a single axle, both tires have a capacity of 3,220 lbs together as long as you are inflating them to max PSI of 65 PSI. If your boat trailer and boat setup weighs 1900 lbs then your tires are appropriately sized. I do recommend to have your trailer and boat weighed to make sure you are not exceeding the weight capacity of the two tires though just to be...

    Yes, to determine the combined load capacity of your trailer tires you would just multiple the single tire capacity by the total amount of tires.

    A 215/65R/15 is not a common trailer tire size. But if the size is actually ST215/65-15 then it can be used on a trailer. An ST205/75-15 tire will have an overall diameter of 27.3 inches and width of 8.1 inches. A 215/65-15 tire will have an overall diameter of 26 inches and width of 8.5 inches.

  • Can etrailer Provide Date Codes For Tires Prior To Ordering?
    While we certainly can provide you with three of the Loadstar ST175/80D 13 Bias Trailer Tires # AM1ST77, we are not able to provide the date code prior to you receiving them. I will say that with the current state of the supply line, most of the tires that we ship are around a year from the manufacture date. It is rare to see a date code more than 24 or so months old, as we generally move our tires fairly quickly. It is worth noting that our warehouse is climate controlled. Most tire manufacturers...

  • Can Radial Tires be Used to Replace Bias Ply Tires on a Trailer
    Yes, you can put radial tires on your trailer to replace the bias ply. You will just need to make sure that the new tires are the same size and load range as the old tires. Radial tires track better and run cooler than bias ply tires. But for either style make sure that the tires are inflated to the maximum psi indicated on the tire sidewall. Trailer tires, whether radial or bias, are made with a thick sidewall so if they are under inflated it will cause the thick sidewall to generate...

It wouldn't be very convenient if you had to inflate the spare tire before use especially if you don't have an on-board air compressor.

  • How to Determine If you Have Clearance to Go from 13 in Wheels to 14 in Wheels on a Travel Trailer
    That really depends on your suspension setup and how much travel the suspension has. Basically if you go to a 14 inch wheel there will be about 1 inch less room between the tire and the fender well and at most an increase in width of 45 millimeters. Without knowing more about your setup the best advice I can give you would be to measure what clearances you currently have with the info I just said in mind and determine if you think you have enough clearance.

  • Is there any Advantage to Going with a Higher Load Range Tire than Needed on a Trailer
    There really isn't any thing substantial that you would notice by going with a higher Load Range than needed. The biggest thing you will likely notice is that the higher LR requires higher PSI in the tires so that means you would possibly spend more time inflating each tire! But that's about it.

  • Moving from Load Range C Trailer Tires to Load Range D Trailer Tires and Radial versus Bias Tires
    The load range has to do with the horizontal and sidewall strength of a trailer tire. The C range tires are 6 ply and the D range tires are 8 ply. Because you are operating at half of the spring capacity of your trailer, bumping to a higher load range won't adding much of a benefit other than giving yourself greater peace of mind. You will adding a stronger tire which can technically create a more rigid ride for the trailer, but this isn't very noticeable when moving up one load rating....

  • Can ST Tires Be Used on a Horse Trailer
    Absolutely. ST tires are designed for trailer use only. The ST stands for special trailer. Provided that you get the right size and capacity for your wheels you can use an ST tire.
