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.

I ordered these tires for my boat trailer as I have a family fishing trip to go on. And to my surprise they sent me two different size tires. Now I am in a bad situation because I have to take the time that I don’t have to call and explain to these people ( if I can get ahold of a person and not a computer) how they messed up my order. Then send the wrong one back and wait for the right one. In the meantime spend more money at a local tire shop for a cheap tire to get me through my trip. Then when the right tire comes in spend even more money having it installed.

I haven't used the tire yet as I purchased it - along with a rim - as a spare for my Teardrop Camp Trailer. But, as usual, etrailer.com comes through with great communication, quick, and best yet, free shipping. I have made a number of purchases from etrailer.com and have never been disappointed! You won't be disappointed either!

Review from a similar Loadstar Bias in Trailer Tires and Wheels
I was surprised to get an invitation to review these tires about a year after purchase. That is a pretty rare commitment to quality and that makes me a pretty big fan of etrailer that's for sure!
When I originally purchase these I recall they were on a back order and took some time to come in, but etrailer was communicative throughout and honored the price at the time of the order even though tire prices were skyrocketing at the time and had gone up considerably by the time they were able to ship. They really are a class act.
As for the tires they are great too!
I had purchased a couple of sets of load range C tires (4.10-8) on rims locally at a big box store prior to this set and had a bunch of problems. They'd air themselves down because of poor fitment to the rim, and dry-rotted and checked within a year of being on the trailer.
These tires on the other hand are excellent in every way. They fit the standard 8" rims properly and hold air and a year later they still look great. They have good side to side traction and handle loading very well. They seem to wear like iron. They are well balanced.
I used these as an up-grade option over 4.10-8 Load Range C tires mounting them myself (I've got a manual tire machine) on the same rims after carefully measuring for clearance on the trailer. This was a good choice for me as even though I don't try to overload the trailer these slightly larger tires provide a better ride under a full load and generally are a tougher tire and better riding.
They travelled 1,300 to KY from MD and back shortly after I mounted them. While in KY I helped my Mom take down an entire garden shed, hauling it, everything that was in it, and a lot of other junk to the landfill in my small trailer (multiple trips). There were times where if I wasn't overloading the trailer, I was definitely at the bitter edge. I felt a lot more confident with these shoes on the trailer than I ever had with any other.
All in all these tires have my confidence and my recommendation!

Review from a similar Loadstar Bias in Trailer Tires and Wheels
Very narrow (where the rubber meets the road). Narrower than my previous purchases/use of 'Loadstar' and 'Carlisle' tires. More appropriate for a motorcycle

- How To Get the Correct Tire Size For a 1985 Scotty CamperYou will want to remove the P165/80D13 tires from your camper because they are only a passenger car tire. A trailer tire will be labeled ST before the tire size to designate a special trailer tire. This will mean the tire is designed with stronger sidewalls to handle the extra loads that a trailer/camper will put on the tire. If you look on the 1985 Scotty Camper identification tag it might include the correct tire size that is recommended for your camper. The correct tire size for your...
view full answer... - Comparing Trailer King RST To Kenda Loadstar ST TiresThe Trailer King RST are a pretty middle of the road tire, not bad but not a top of the line tire. On the other hand the Kenda Loadstar ST tires are a high quality tire designed and strenuously tested in Ohio to make sure the tires are as reliable, and strong as possible. The Loadstar ST tires included a 1-year worry free guarantee and 5 year limited warranty which shows how confident Kenda is in the tire, where Trailer King tires only have a 5-year warranty. With that said, the Loadstar...
view full answer... - 13 Inch Diameter Tire with 6 Inch Section WidthThe narrowest 13" diameter tire we offer is the Loadstar ST175/80D13 Bias Trailer Tire part # AM1ST74 for load range B, part # AM1ST76 for load range C, or part # AM1ST77 for load range D. These tires all have a section width of 6.6". In order to obtain a section width of 6.0" you would need to go down to a 155/80-13 tire which is a very odd size so if you can give me a bit more insight as to what you are trying to accomplish I would be glad to see if we have any better options for you....

We have the Loadstar ST175/80D13 Bias Trailer Tire - Load Range D # AM1ST77, the Loadstar ST175/80D13 Bias Trailer Tire - Load Range C # AM1ST76, and the Loadstar ST175/80D13 Bias Trailer Tire - Load Range B # AM1ST74. The difference between these are their load capacity and ply rating with the strongest being the Load Range D tires.

You will want to make sure the load capacity of 1,100 lbs. at 35 psi will be sufficient for your trailer. I also have the Karrier ST175/80R13 Radial Trailer Tire-Load Range C, # AM10199, which is a radial tire in that size and has a load capacity of 1,360 lbs. at 50 psi. You will also want to make sure and inflate the tire to the maximum psi that is listed on the tire. Trailer...

The Kenda tire you referenced, # AM1ST74, is a radial trailer tire in this size. We also offer it pre-mounted on a 13-inch white wheel with a 5 on 4-1/2 bolt pattern as part # AM31985. This combination is rated as Load Range D, with a maximum load capacity of 1,610 lbs at 65 psi. Trailer tires should always be inflated to their maximum psi pressure as indicated on the tire's sidewall. An...
view full answer... - Which Trailer Tire Size Replaces B78-13B TiresB78-13 is an old tire size designation that isn't used much anymore. The modern trailer tire equivalent size is ST175/80-13. All of the tires on the trailer should be the same size, load range, and construction type (radial or bias ply). Having one that is a different size can cause uneven tire wear, tracking problems (how the trailer follows the tow vehicle), potential suspension issues, and unspecified weight carrying capacity. The 175/70-13 isn't a trailer tire size. If the tires on...
view full answer... - Option to Replace 155/80-13 Size Trailer TiresIf you go up to 175/80-13 sized tires, like # they will be about 1-1/2 inches larger in diameter and about 1/2 inch wider. You want at least 3 inches between the tread and fender and an inch between the sidewall to the inside of the wheel well. If you have the clearance it will be better to go with the larger tire than the smaller. If you go down to the 145/R12, like # AM35354, or the 5.30-12 like # AM35354, you'll have tires that are about an inch smaller in diameter and about a 1/2...
view full answer... - Replacement Tires For an Old Trailer With B or D 78-13 TiresIt is most likely a 78-13 as that was an old tire size that was discontinued. The closest replacement is a 175/80-13. The B or D is in reference to the weight capacity of the tire. A Kenda ST175/80D13 Bias Trailer Tire # AM1ST74 has a load rating B which is 1,100lbs per tire for this size. The Karrier ST175/80R13 Radial Trailer Tire # AM10210 has a load rating of D which is 1,650lbs per tire. To determine which will work better for your trailer you can determine what your GVWR is...

It also comes in load range C, # AM1ST76 for bias ply or # AM10199 for radial, both rated for 1,360 pounds at 50 psi. And there is also a load range D in this size, # AM1ST77, for bias ply and # AM10210 for a radial both rated for 1,610 pounds at 65 psi. Radial tires run cooler and track better than bias ply tires but bias ply tires are better...
view full answer... - Can You Upgrade ST175/80D13 Tires On Utility TrailerIn order to determine if you can upgrade tire sizes you'll need to measure for clearance. We recommend 3" on top and 1" inside the existing tire. If you have more than this then you can move up a size, the next largest would be a 185/80-13 such as the Castle Rock ST185/80R13 Radial Trailer Tire part # LHCK105 (24.6" Diameter x 7.2" Wide). If not it's best to stick with the same size you have such as the Loadstar ST175/80D13 Bias Trailer Tire part # AM1ST74 (24" Diameter x 6.6" Wide).
view full answer... - What Does Trailer GVWR Mean for Maximum Cargo Weight Capacity and Can it Be IncreasedWhen a manufacturer indicates a trailer's GVWR, which is the most it can ever weigh under any circumstances, this consists of the weight of the empty trailer itself plus the maximum cargo weight you can put in it. Under no circumstances do you want the loaded trailer to weigh more than the manufacturer's rated GVWR. Sometimes trailer makers may install axles whose combined rating is not exactly the same as the specified GVWR. The total axle capacity could be more than or slightly less...

view full answer... - Trailer Tire Replacement for Size A-78-13Since your trailer uses lug bolts to secure the wheels to the hubs that means the hubs are hub-centric which means that the pilot hole of the wheel is what centers the wheel to the hub. To replace wheels you'd have to go with wheels that have the exact same pilot diameter as what you currently have so that it centers properly. We can help you replace just the tire though. The metric equivalent of an A78-13 tire is a 175/80-13. This size is available in load range B, # AM1ST74, rated for...
view full answer... - What Trailer Tire Size is the Right Replacement for A78-13 TiresBy definition an A78-13 tire cannot be mounted on a 14 inch wheel since it is a 13 inch tire. Wheel diameter is tricky. When measuring them you do not actually measure the total height of the wheel so you likely have 13 inch wheels. A78-13 is an old way of indicating a tire size. The metric equivalent is ST175/80-13. Since you have a 5 lug wheel it is likely a 5 on 4-1/2 inch bolt pattern. You can measure by following the help article I have linked for you. But if you just need tires...
view full answer... - Can Tire be Purchased Separately of the Loadstar ST175/80D13 Bias Trailer Tire with 13 Inch WheelYou can get the tire (and the wheel) separately if you like; you don't have to get the tire/wheel combo of the Loadstar ST175/80D13 Bias Trailer Tire with 13" White Wheel # AM3S030. If you want just the tire from this combo, what you need is the Loadstar ST175/80D13 Bias Trailer Tire # AM1ST74.

A 175/80-13 is going to have 3 load ratings: B at 1,100 pounds at 35 psi part # AM1ST74, C at 1,360 pounds at 50 psi # AM10199, and D at 1,610 pounds at 65 psi # AM10210.

You mention having a 175/80-13 tire for which we do have a load range B # AM1ST74 (1,100lbs), C # AM10199 (1,360lbs) and D # AM10210 (1,650lbs). By moving to the higher capacity tires you do get a stiffer tire which will create a stiffer ride for your trailer giving you more bouncing as most trailer tires also act as shock absorbers.

If you were wanting a ST175/80D-13 Load Range B tire such as what's used on the # AM3S030 wheel/tire combo, you'd purchase part # AM1ST74. If you'd prefer the better ride quality and cooler running provided by a radial tire, use part # AM10210. The radial tire is in a higher load range, but it'd still work great for you.

It is also important to note that trailer tires should always be inflated to their maximum psi. The max psi will be noted on the tire's sidewall. If you need a tire with load range B, I recommend the Loadstar Bias Trailer Tire # AM1ST74. This tire has a max load of 1,100 pounds at 35 psi. You will want to double check your bolt pattern, but if you need a tire and wheel with 5 on 4-1/2...
