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! 416955

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. 562575

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! 43492

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 127434


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!

Great service from eTrailer.com. Tires got here in three days. Well packaged and in great shape. These are excellent tires. This is my second set and the first set performed beautifully. Rarely had to add air and the ride was smooth as glass. I did have them balanced when mounted. Never had a problem. Tread on the outer edges was showing wear after four years so I went ahead and replaced them. Probably could have gotten another year our of them, but I erred on the side of caution. 540760

These tires are great for my Fleetwood redwood Popup, actually were original equipment when my popup was new. I looked everywhere, this is the best tire you can get in this size, etrailers price was great when you figured the free shipping, got them within a weeks time. Walmart mounted them and did heavy duty valve stems and kept the old tires for a total of 18.00 Make sure you run these at max pressure to insure even wear, previous owner of my popup ran them low and I had serious wear on the outer edges I run my tires at 65psi 53104

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! 177733

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. 301932


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!!!

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. 175760

We bought out pop up trailer new in 2009 - it's now 2017 - and felt although the tires don't look bad, we better replace them. I called around my local tire places and found none had the factory replacement in the Class (D) that I needed. I called etrailer and they had them. I wanted to ask some questions regarding bias versus radial and the tech was very helpful. I then called around my local tire stores to see if I buy them on-line would them be able to mount them. This was not an issue. I called etrailer back and the sales person I had was a joy to talk to. It just felt like I was buying with someone I've known. We made some small talk while the order was being processed. The experience was just enjoyable. The tires came in a few days and I'm having them mounted tonight. As a matter of fact he tires are only a couple weeks old - so a great turn around of product. Remember me mentioning my trailer was an 09, well turns out the tires we dated 2006. So my brand new trailer had 3 year old tires on it right of the show room floor. Hope the new ones last as long as the first set. 426855

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. 136606


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.

Well, have put about 2500 moles on them. Starting to notice wear on the outside edges of both tires. Tow nicely tire pressure holds well

Greg - 03/17/2019

Typically, wear on the outer edge of the tire tread is either caused by improperly inflating the tires or by worn suspension components. A trailer axle will have a bow or arch in it so that when the weight of the trailer bears down on it, the contact patch of the tires to the pavement is even across the tire. This won't be the case if suspension components are worn or damaged. I'd recommend checking your tires for proper inflation as well as taking a close look at the trailer suspension. Are the holes in the shackle links ovaled out? any broken leaf springs? Bent axles or spindles?

Tires are tires but not all are equal. I purchased two of this tire to upgrade the size and design of my tires. These tires seem to be as advertised and I am pleased with the design. I will followup when I have had time to use these tires but I am fairly certain the bias ply design will be better than the radials I had on the trailer. I would buy them again. 415064

This rating is for customer service and assistance in purchasing new tires for my pop-up camper. Since I have just received the tires I can't honestly rate them. But if they perform as well as ETRAILER I'm sure I will be a happy camper. I ordered the tires on Thursday and they were delivered the following Wednesday. Thanks for the recommendation, the quick delivery, and a fair price. I'm sure this won't be my last purchase. 400746

I have made several long distance and a few shorter trips with these tires over the past year. The roads vary from Interstate Highways to country backroads. The tires have performed flawlessly under a wide variety of weather conditions. I am completely satisfied. And as I predicted this wasnt my last purchase from etrailer. Thanks for great products and great service.

On a vacation trip the tire on our popup camper blew. We tried to find the tire at local shops but came up with a similar tire that was not rated for the camper. The only place we were able to locate the correct tire was on this site. We ordered 2 of these tires which were delivered very quickly. A local shop was able to mount the tires and they work very well on the camper. It was very easy to find the needed tires on your site. We would definitely look here if the need arises again and will definitely recommend it to friends. 387065

  • 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,...

If you decide to go with the radial you can use the ST175/80R13 radial tire and 13-inch 5 on 4-1/2 wheel combination such as part # AM31985.

  • The size difference between the Kenda Karrier ST175/80R13 Radial Trailer Tire - Load Range D # AM10210 and a 185-80R13 tire is the diameter and the width. We don't have any radials in that size, so I'll compare to the similar Kenda Loadstar ST185/80D13 Bias Trailer Tire - Load Range D # AM1ST79. The 175/80-13 tires have a diameter of 24.1 inches and a width of 7 inches compared to the slightly larger 185/80-13 tires that have a diameter of 24.4 inches and a width of 7.2 inches. The...

  • Can I Switch from ST185/80D13 to the ST205/75R14 on a 2009 Jayco 17C Ex-Port
  • It is always recommended that you use the original tire and wheel size that came on your camper but I have calculated the size differences between the two tires. Your current wheel/tire combination, ST185/80D13, has an approximate width of 7.28 inches and is 24.66 inches in diameter. The ST205/75R/14 has an approximate width of 8.07 inches and is 26.11 inches in diameter. The variance in the dimensions are very minimal so you should not have any difficultly making the switch. Just a quick...

  • Availability of an ST185/80-13 Load Range D Radial Trailer Tire
  • All of the 185/80-13 trailer tires that we carry are bias ply tires. No radials available in that size. Bias ply tires are better for rougher roads, agricultural applications, due to the strength and toughness of the design. They work fine on pavement as well. Radials will track better and run cooler on pavement though. In a load range D bias ply we have # AM1ST79. The radial tire # AM10210 is a 175/80-13 load range D rated for 1,610 pounds at 65 psi. It will be a little more narrow...

  • Highest Capacity 13 inch Trailer Tire Recommendation
  • If the total weight of your pop up camper is 3,300 lbs then you would need a wheel/tire combo that at least has the capacity of 1,650 lbs. The closest tire we have to that capacity in your size is the part # AM10210 which has a 1,610 lbs at 65 psi capacity. Your best option would be to bump up to the slightly taller tire size of 185/80-13 like part # AM1ST79 which has a 1,725 lbs at 65 psi. This tire fits the same rim size as your current size and is not even 1/2 an inch taller in...

  • Loadstar ST185/80D13 Bias Trailer Tire # AM1ST79 Recommendation for a D78-13 Trailer Tire
  • The correct size tire you would need to replace the D78-13 tires that are on your trailer is ST185/80D13. I would recommend the Loadstar ST185/80D13 Bias Trailer Tire, part # AM1ST79. I attached an FAQ article on tires below for you to check out also. If you need a wheel and tire combo on a 5 lug on 4-1/2 inch bolt pattern I would recommend the Loadstar ST185/80D13 Bias Trailer Tire with 13 inch Galvanized Wheel - 5 on 4-1/2, part # AM3S334.

  • Is a C Range 205/75-14 Tire Less Likely to Fail than a D Range 185/80-13
  • When 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...

  • Choosing Between Radial and Bias-Ply Tires for Coleman Bayside Pop-Up Camper
  • When the option is available, I always recommend going with a radial tire versus a bias-ply. The ride quality will be noticeably smoother and more stable. Radial tires do a better job shedding heat, and since excessive heat is the number one reason for tire failure, you'll typically get more life out of a radial tire. We offer a ST185/80/D13 tire in bias-ply only, that part # is AM1ST79. We offer the ST175/80/D13 in either radial, part # AM10210 or bias-ply, part # AM1ST77. Although...

  • Should Radial or Bias Tires be Used for a 3500lb GVWR Pop Up Camper Trailer
  • I can clear this up for you really quick. Radial tires run cooler and track better than bias ply tires. Bias ply tires are typically a little more heavy duty and better for rough terrain. But you can use either one provided that the size and capacity is enough for the trailer. It is usually best to stick with the tires recommended by the trailer manufacturer. In this case it would be a bias ply tire. For just a tire in an ST185/80-13 we have # AM1ST79 which is rated for 1,725 pounds...
