1-Year Worry-Free Guarantee
This tire has a 1-year worry-free guarantee. If within the first 12 months the tire is damaged in any way, it will be replaced at no charge.Bias Tires vs. Radial Tires
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 ordered and paid for TWO TIRES. Receive one… check my order. I NEED THAT 2nd tire ASAP.

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.

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

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.

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.

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.

Replacement tire works great.
by: Jim D05/13/2015
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: Eric O02/02/2016
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.

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!)

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!

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.

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: wes w07/17/2017
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: David B.08/10/2017
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: Eric02/07/2019
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.

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: Mike K.06/21/2016
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: Major F09/25/2020
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.

The tires are perfect sfter a year. I recomend these tires.
by: Larry W05/03/2019
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: H. Fry04/20/2017
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.

- How to Choose Replacement Special Trailer Tires for 2004 Bass Tracker 185 Boat TrailerThe primary things to consider when selecting replacement trailer tires are the total weight load they must carry and the type of driving you'll be doing, say either off-road travel deep in the woods or mostly on the interstate at or near the speed limit. These questions will help you determine which tire weight Load Range you need and whether a bias or radial tire will be better. Radials are superior for higher-speed highway travel since they flex more and run cooler; but a bias tire...
view full answer... - How To Determine The Axle Rating Of Axle On Boat TrailerThere are a few different ways to determine the weight rating of your axle. The best way is to look for the axle tag on the center of the axle and you will see the axle rating on that tag. This is the only way that will give you the exact rating of the axle. Now if the axle tag is missing or not readable then you can take the GVWR of the trailer and divide it by the number of axles on your trailer to get a rough idea of your axles rating. Lastly you can remove one of your hubs and look...

- Should Trailer Tire Really be Inflated to Max PSI RatingOn any trailer tire you always want to inflate the tire to the maximum cold psi, which on your tire is 50. This ensures you get the full weight capacity and prevent heat build up which can cause failure.
view full answer... - Should Tire Pressure Lower Than Sidewall of Tire be Used to Account for Heat Build-UpIf the psi rating stamped on the sidewall of your ST175/80R13 size tires on your 1995 Dutchmen Pop-Up Camper is 50 then that is what you need to fill them to with the tires cold (sitting for a long period of time like overnight). The manufacturer has already taken into account that the psi rating will increase once the heat builds up in the tire and they have deemed that 50 psi is the proper rating for safe use with this tire. Technically you can run it at a lower psi but that would change...
view full answer... - Determining Combined Load Range of Trailer Tires 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. For example, the Kenda Loadstar ST175/80D13 Bias Trailer Tire # AM1ST77 that you were looking at features a 1,610 pound maximum load at 65 psi. Assuming all four of your camper's tires are filled up to their max 65 psi, this would provide you with a combined tire load capacity of 6,440 pounds. As long as this meets or exceeds your trailer's...
view full answer... - Can a Boat Trailer go From E78-14 Tires to 185/80-13The closest trailer tire size to the E78 14 ST tire is a 205/75-14 tire which has an overall diameter of 26.3 inches. The 185/80-13 tire size has an overall diameter of 24.1 inches. So basically you would lower your trailer a little over an inch by doing this. The biggest thing you will need to do is verify that you have a 5 on 4-1/2 inch bolt pattern (see link) and that you would have enough capacity. A wheel like the part # AM3S334 has a capacity of 1,660 lbs at 65 psi per wheel.
view full answer... - Tire Recommendation for a Trailer Used on Paved and Dirt Roads Size 175/80-13The best tire for your trailer will really depend on how much time you spend on paved roads versus dirt or gravel roads. At the 175/80-13 tire size, you can choose between a radial tire and a bias ply tire. Radial tires, like part # AM10210, have more flex, better ground contact, traction, tread wear and runs cooler than a bias ply tire. A bias ply tire, like part # AM1ST77 has a thicker sidewall and is ideal for off-road use, but if you spend more time traveling on paved roads, a radial...
view full answer... - 175/80R13 Trailer Tire Recommendation with Speed Rating Higher than 65 Miles Per HourI have a solution for you, but the speed rating for the # AM1ST77 is 65 miles per hour. For a tire in the same size with an 87 miles per hour speed rating you would want the part # TTWTRTM1758013C.
view full answer... - Can Radial Tires be Used to Replace Bias Ply Tires on a TrailerYes, 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...
view full answer... - Load Range of 205/75R15 TireThe bolt pattern of your wheel is irrelevant to the fit of a ST205/75R15 tire, what matters is that your wheel is 15" in diameter. Additionally, the largest load range we carry in that size is D, which you can move up to though that will not equal the 5,000 lb capacity of your axle. What will give you more than that capacity is a ST225/75R15 tire like the Karrier # AM10256. This tire has a load range of D and has a maximum capacity of 2,540 lbs at 65 psi; for a load range E ST225/75R15...
view full answer... - Radial or Bias Ply ST175/80-13 Trailer Tires for a Boat TrailerAn ST175/80-13 trailer tire load range C (the ones we carry) is going to have a 1,360 pound capacity at 50 psi, bias or radial. So 4 of them total on a tandem axle trailer is going to have a capacity of 5,440 pounds; more than enough for the 4,500 pound estimated weight of the trailer loaded and ready to tow. Typically trailer tires fail because they are either ran at the wrong psi and get too hot or because they are overloaded. It is also possible you just got some bad tires. If you are...
view full answer... - What Does the R Stand for In a Trailer Tire SizeThe R in the ST20575R15 stands for radial which is the way the tire is constructed. The main difference between a radial ply and a bias ply tire is how the tire is constructed. The cords inside a bias ply tire run at a 32 degree angle to the direction of travel, and the cords on a radial tire run at a 90 degree angle to the direction of travel, or across the tire from wheel lip to wheel lip. A radial tire flexes more than a bias tire, giving it better ground contact, traction, stability,...
view full answer... - Is a 10 PSI Increase in Trailer Tire Pressure Normal from Heat Created by DrivingAs long as you aren't exceeding the speed rating of the tires which would cause them to get to an excessive heat you are fine. Trailer tires are designed to be inflated to their max PSI rating when cold and then the pressure increase from heat from the road is normal and safe. You just need to verify you aren't exceeding the speed and weight rating and you are safe and would want to increase that alarm's threshold.
view full answer... - Travel Trailer Tire Size Recommendation for ST205/75-14The ST in front of the first tire size you mentioned is very important for trailer applications. This indicates that the tire was designed for trailer use. If the tire size you are considering does not include this then you should not use this tire as it won't be rated properly due to it not being designed to handle vertical weight trailers see. Most likely it was intended for a passenger vehicle application instead. For a tire in this size I recommend the Westlake part # 274-000012 because...
view full answer... - Replacing B78-13ST Trailer Tires on a 1991 Coleman Pop Up CamperThe modern equivalent to a B78-13ST is going to be a 175/80-13 trailer tire. The tires and wheels that we have in this size come in 2 different bolt patterns, 4 on 4 or 5 on 4-1/2. For a 4 on 4, in a galvanized wheel like the one you have referenced, we have # AM3S130. This is a load range C tire with 1,360 pound capacity at 50 psi. For a 5 on 4-1/2, we have # AM31242, that you have referenced. This is a load range D rated for 1,660 pounds at 65 psi. If you just want the tires and not...
view full answer... - What is the Difference Between Load Range C and D ST175/80D13 Trailer TiresThe difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like # AM1ST77, the capacity is 1,610 pounds at 65 psi. For a C load range in the same size, like # AM1ST76 , the capacity is 1,360 pounds at 50 psi. Adding the D load range tires of the same size will fit your trailer, but they will not allow you...
view full answer... - Is there any Advantage to Going with a Higher Load Range Tire than Needed on a TrailerThere 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.
view full answer... - What Does the C Mean on a Tire When at the End of the Size 235/65r16CThe 235/65r16C is the size and the C on the end signifies they are Euro-Commercial tires which means the tires are appropriate for that vehicle based on the Euro standards. These are passenger tires and not trailer tires, so if you have those tires on a trailer, I definitely recommend replacing them with ST (special trailer) tires that are made differently for trailer use. If that is the case, I have linked the page to all our 16 inch tire options to assist. That C is not the same as...
view full answer... - Trailer Tire PSI for Best Traction and FunctionTrailer Tires that have the ST in front of the numbers are special trailer tires designed to be run at their max psi when inflated cold (prior to trip). They will warm up and that psi will actually increase as the friction and ambient temps increase. It may seem like a lot, but under inflation will actually cause premature wear and possible failure as the sidewall of these tires are designed to be firm and under inflating them will make them fail. Under inflating compromises the load...
view full answer... - Is a C Range 205/75-14 Tire Less Likely to Fail than a D Range 185/80-13When comparing the 175/80-13 and the 185/80-13 tires, load range D, there is not much difference. The larger 185 is going to be about 0.3 inches taller, about 3/8 of an inch wider, and have a higher capacity at 1,725 pounds at 65 psi. Both sizes will fit on the same rim. Please note the higher capacity does not allow you to carry more weight. Trailer tires should also always be inflated to the maximum psi rating indicated on the tire. The next size up would be a 205/75-14. This of course...
view full answer... - Does Heat Inflate Trailer TiresTrailer tires such as the Loadstar ST175/80D13 Bias Trailer Tire # AM1ST77 are actually designed to over-inflate somewhat from their cold PSI rating, which is given to the tire to ensure it performs optimally. You always want to inflate the tire to the maximum cold PSI, which on this tire is 65. Doing this will give you the best performance, allowing the tire to wear more slowly and give you optimum gas mileage; it will not damage the tire. We do recommend using radial tires like the...
view full answer... - What Pressure Should Trailer Tires be Inflated ToWith trailer tires you need to run them at their max psi rating at all times to ensure you get the full weight capacity of the tire as well as prevent heat build up which eventually causes tires to fail. I attached a help article on trailer tires for more info for you to check out as well.

It is very possible because of the capacity of your tire that your tire is rated too high. My recommendation is to instead use Kenda 215/60-8 Bias Trailer Tire with 8" Galvanized Wheel - 4 on 4 - Load Range C # AM3H300 which is rated for a max load of 940 lbs at 50 psi and speeds up to 65 mph.

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.
