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.

This is the first time I have ordered trailer tires from Etrailer and I did not know what to expect with regard to service and product quality. The last pair of tires I had on my pontoon boat trailer were 185/80R13 Marathon tires but according to the specifications, the Etrailer 185/80R13 tires had a better load rating and higher safe speed rating than my old Marathon tires. My Etraier tires also have a 2/2018 date of manufacturing which was also a plus.


Comments
Great ... I sold my pontoon boat recently but the tires exceeded my expectations. I now go to Etrailer for tire recommendation and technical advise. I recently bought a spare tire and rim for my new Venture trailer from Etrailer. Thanks, PW

Tires arrived quickly, package well, and best of all they are only two months old. Will evaluate tires as time goes by, but etrailer.com did a great job of fulfilling my order.

After researching tires for several days, watching etrailer videos and reading all the Q&A's, I decided on this particular size and brand because they're excellent in quality and couldn't find any local dealer that carried them. I ordered the tires, steel wheels and baby moon hubs all together to go on a 15' Scotty camper. They look great and I would recommend them to anyone who needs a smaller, yet durable tire.

These tires are great! Not too many miles on them yet but they ride well. The load range of these tires is great too. The awesome part of this purchase was the tires shipped the same day I ordered them and they arrived in four days! Great customer service!

I have never ordered tires online or for a trailer before this experience. They had exactly the tire that I wanted in the correct size that I wanted. That made it very simple to just call them up and order. We received the tires in 3 business days. We have not taken a trip on these tires yet but I expect them to be just fine when we do. If you are looking to replace original tires for your camping trailer, this is the place to look first. I will return here for future trailer needs.


Comments
Only took one trip on them last summer. One tire went flatlow sitting over the winter. We have kept it aired up during the spring, not sure if this is due to the tire or how they were installed on the trailer. never had that happen on the original tires in 6 years. So a little worried about what might happen on the one trip we plan to take this summer. any advice?
Melissa K - 06/19/2015

The problem you are describing may be associated with how the wheel was installed on your existing rim, or potentially with the valve stem. If the tire is no seated properly on the wheel, and if the valve stem is bad, or does not have a good seal, you may experience slow air leaks overtime.

So this is the second set of these I have ordered for my 2001 Palamino Pop Up. The first set held air pressure all 10 years I had them and we took 25 trips with them (I just checked that fact the other day). So we had no problems until one popped on the interstate. At 10 years old, not a surprise nor disappointing. Now the last set I ordered were already on rims mounted and balanced. These new ones came packaged as tires only. The my are way deformed for shipping and folded on half. We will see if they right themselves under air pressure. Not sure how they will get mounted. I used a mounting and balance machine a long time ago only an Army auto craft shop. Can’t imagine how these will turn out. I will update my rating if the experience is a debacle. If the tire shop thinks nothing of it, I will leave myv5 star rating as is.

I bought these tires to put on my travel trailer. The outside and inside treads are wearing faster than the 3 center treads. I always check the pressure before getting on the road and both tires are inflated to 65 pounds. I only have 18 thousand miles on them. I'm very disappointed in the wear pattern.


Comments
Tire treads that are worn at the edges would typically indicate an under inflated tire. Have you tired a different tire gauge in order to confirm your readings? If the pressure is fine, a bent axle or worn suspension parts could certainly cause the wear you describe, as well. The tires are covered by a 2 year warranty. Please call our Customer Service folks at 800-298-8924 for details.

I placed my order on Friday and had my tires by Tuesday. Excellent customer service and no shipping fees to boot. Easy ordering, no hassle and they kept me informed all along the way of where my tires where. I have not worked with this company before, but will in the future when there is another need. I would recommend etrailer to friends and family. Totally satisfied customer


Comments
I ordered my tires on a weekday and poof they appeared within a day or two. Awesome customer service. I ordered 2 replacement tires and shortly thereafter I sold my popup to my brother who drove it from North Carolina down to the Keys where he lives - he has made multiple trips throughout Florida and has not had any problems at all with the tires and wanted to make sure he knew where I purchased them when it time to replace. Will definitely be a repeat customer. These people do an awesome job!

I wore the original tires out on my utility trailer by running them underinflated, so I saw these on etrailer site. had a couple good experiences ordering from these folks getting light parts that I couldn't find local, so I thought I'd give these a try. They came in a timely manner... wouldn't mount themselves,lol, but have started wearing these out already, satisfied with them so far and would recommend the tires for your use and e-trailer as a source for whatever else you might need

by:

Very timely shipping and packaging to prevent any damage



- AM1ST79
by:

Tires were sent very fast and well packed in a box, not just shrink wrapped. The tires themselves are by far a better tire than what came on my boat trailer. They are almost twice as heavy as the originals and much stiffer sidewall. They pull better than the old tires ever did. Their price beat any I could find here on a comparable tire. I will be getting in touch with them when I need tires again. I would rate them A- double plus.


Comments
I have put many miles on these tires, including many back roads and trails, and have had no problems with the tires. They show very little wear for the amount of miles and abuse they have had. Would I buy them again? In a heartbeat!!!

I can't say enough good things about etrailer. They had exactly the same brand and model of tire that originally came on my camping trailer. Those tires lasted 14 years according to the tire shop that mounted the new one. So, they clearly carry quality. What always amazes me is the speed of shipping. I ordered this tire on a Friday at 12:45 PM. I got an email at 9:15 PM that day saying it had shipped. It arrived at my door before 9:30 AM on Monday. Now that is great service! Love the product selection, all the helpful information, and certainly the speedy service. They've certainly set the bar very high for any competition.

I recently purchased two Loadstar ST185/80D13 Load Range D Bias trailer Tires. This was a difficult item to find looking locally, online, or even calling several manufacturers and distribution centers. These tires are for our family's 10 yr old popup camper which on the last trip had a blow out and needed to have them replaced before our summer trip. I found them on etrailer at a fair price and made the purchase late one evening. By morning I had received two emails notifying me that the product had shipped and that shipping had been upgraded to 3 day with no extra cost. The tires arrived on time at my parents home where the camper was stored and the tires were installed by a local installer that afternoon. Thanks etrailer for making our summer camping trip possible and hope others find your services as beneficial as we did. Happy Trails!

These tires seem to last a long time. I just keep wear the rubber down because of all the towing I do. Never had to replace one because of cracking. I love them. I just keep replacing the spare.

We put these tires on our 23 ft. camp trailer. They have been one of our best investments! Even after sitting all winter, we did not have to add any air when getting the camper ready for summer camping season! Definitely an improvement over the D rated tires that came with the camper originally!

  • Best Trailer Tire for Rockwood Camper with Tire Size 185/80-13
    If your 2016 Rockwood Aframe camper A192HW has a tire size of 185/80-13 then the best tire we have as a replacement would be the Kenda part # AM10208 which is the size you need but it's a radial and the one you referenced is a bias ply. The main difference between a radial ply and a bias ply tire is how the tire is constructed.

  • Difference Between 80R13 and 80D13 Tires on Boat Trailer
    Great question! The difference is that the "D" in the 80D13, like the Kenda # AM1ST79, means it is a Bias ply tire where the "R" in the 80R13, like the Kenda # AM10208, means it is a Radial ply tire. Bias tires are the original trailer tire and do a great job. They have a stiffer sidewall which makes them better for off-road and agricultural trailers. Radials are the "new" kid on the block and are designed more for highway trailer use. They have more flex in the sidewall which helps...

  • Replacement Tire Recommendation for an ST185/80R13 Size Tire on a Travel Trailer
    The load range D on the Loadstar ST185/80D13 # AM1ST79 actually gives you a higher weight rating than the C load range. For this size D is 1,710 lbs at 65 psi while C is 1,480 lbs at 50 psi. It doesn't hurt to have a tire that is rated for more weight and the benefit to this tire is that it has a max speed rating of 81 mph. If you need a wheel as well then I recommend part # AM3S331 as this is the same tire but it comes with a white wheel that has a 5 on 4-1/2" bolt pattern. Bias tires,...

  • What is the Right Tire Size for a 1998 Coleman Destiny Mesa Pop-up Camper
    The 1998 Coleman Destiny Mesa uses 13 inch tires. What I could not find was if it takes the more common 175/80-13 or the wider but much less common 185/80-13. This information could be on the trailer's ID tag. If it were me I would go with 175/80-13 tires such as # TTWTRTM1758013C, This tire is rated for 1,360 pounds at 50 psi.

Bias ply tires have belts that go front to back or at an angle across the tire. Radial tires do run cooler which is why they are great for pavement.

    The closest metric tire size to your C78-13ST Sport Trax tires is 185/80D13. The tire that I recommend using is the Kenda Loadstar ST185/80D13, # AM1ST79. This is a Load Range D tire that is rated at 1,725 lbs at 65 psi. This tire will fit 13 inch wheels that are 4-1/2 inches, 5 inches or 5-1/2 inches wide. At this time we do not carry a load range C tire in this size. Keep in mind, increasing the weight capacity of the tires will not increase the carrying capacity of the trailer.

  • Availability of ST185/80R13 Size Tire for Boat Trailer
    Although we currently do not carry the Radial version of the ST185/80-13 Load Range D Kenda Loadstar tire, we do carry the Bias version which can be found with part # AM1ST79 on our site. Since this tire uses the special trailer tire design (ST) it has the strength of a bias tire but also the durability and stability of a radial tire. The max load rating for a single tire is 1,710 lbs at 65 psi and this tire has a max speed rating of 81 mph so you can rest easy about your speed on the...

  • Larger Trailer Tire to Replace Size 175/80 R13 Load Range C
    Yes, assuming you have the clearance between the tire tread and underside of the fender. You'll want at least 3 to 4 inches to allow for the trailer to go over bumps in the road. However, if you plan to keep the 13 inch rim there isn't much taller you can go. The 185/80D13 sized tire # AM1ST79 is only about 0.3 inches larger in diameter compared to what you have now. If you increase the rim to a 14 inch the # AM32161 is a 205/75R14 that would increase the total diameter by a little...

  • Higher Capacity Wheel and Tire Recommendation for Trailer Size 185/80R13
    In the tire size of 185/80-13 the highest Load Range we have is D like the part # AM1ST79 which has a capacity of 1,710 lbs when inflated to 65 psi. The only way to significantly increase your tire capacity will be to go to a 14 inch wheel and tire combo like the 205/75-14 with something like the # AM32161 which has a 2,040 lbs capacity.
