When you’re towing long distances or hauling in hot conditions, this tire is built for it. The Kenda Loadstar ST185/80D13 bias tire carries a Load Range D rating with an 8-ply construction and handles up to 1,710 lbs at 65 psi. It’s speed rated M for 81 mph and exceeds DOT requirements, giving you confidence mile after mile on the highway.
This isn’t a light-duty tire. The bias ply design uses nylon cords set at a 30- to 45-degree angle in crisscrossing layers, creating stiff sidewalls that hold up under heavy loads and flex evenly across rough ground. The advanced rubber compound helps extend tread life and reduce rolling resistance, keeping the ride smooth while resisting heat buildup.
The ST185/80D13 size fits 13" x 4-1/2", 13" x 5", and 13" x 5-1/2" wheels, measures 7.2" wide, and stands 24.4" tall when mounted and inflated. That footprint gives you solid stability with flatter tread contact for consistent handling and braking performance without wandering or sway.
Every Loadstar ST185/80D13 bias tire comes backed by a 5-year limited warranty and a 1-year worry-free guarantee that replaces the tire if it’s damaged within the first year. It’s confidence you can count on before you even hit the road.
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Loadstar ST185/80D13 tires are replacing the ST 175/80C13 on my Scamp camping trailer. These are the only tires that have a 1725 lb load rating in this size. The rest of the tires are hundreds of lbs less and do not allow much of a safety margin when the camping trailer is loaded. First time buying Kenda trailer tires. I have had great tread life and road handling with my Kenda motorcycle tires.
etrailer.com has great info on their web site and the tires were quickly delivered in boxes, not just shipped naked with a shipping label on them.
This is the only tire I can get in this size with a 8 ply. They did not wear very well! Service was awesome as usual.
I used these on my ATV trailer...The Load Range D makes a huge difference over the Load range C sidewalls. No more bouncing or swaying from sidewall flex. It really improved the ride quality of the trailer and are much tougher than most other trailer tires offered for a 13 inch rim.
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
these tires lasted two years, I have put about 20,000 miles on them on a coleman popup very happy and I did buy them again very good delivery and free shipping.

Still satisfied
Perfect! Exact replacement tires for my 26’ enclosed snowmobile trailer! I’ve always loved dealing with etrailer in the past and what makes it even better was they had the best price! Excellent quality. FAST shipping!

Tires are still running strong!
This buldge doesn’t seem correct.

These tires are shipped flat and should take a normal shape once the tires are inflated.
Super fast shipping. I buy new tires every five years for my pop-up, and with the Loadstar tires have never had a tire issue. I am very satisfied with the service I get from these tires. Also, E-trailer has the best price that I have found anywhere. I would recommend these.

working great.
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.

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 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

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 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.

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?

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.

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.
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.

The tires are perfect. They mounted just fine and ride just fine. Still holding air and haven’t added any in a year. We don’t pull it much these days, but I am confident I have a solid tire.
Excellent order with fast Delivery and they exemplify my rims and trailer.
Trailer spare tire, have never used it.
Nice tires. Just towed trailer today 105 miles. No problems.
Ordering was easy based on clear specifications. They will be properly tested shortly.
Got new loadstar tires for my coleman Fleetwood Rio they look great and ride even better. The ride over all is smooth and stable.
Nice tread and no problems
These seem to last a lot longer than the load C tires. They have worked great on my hunting boat trailer.

Tire is running great and wear just like it should.
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!
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.
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 having these tires for a year, I must say I am pleased. They are wearing well, hold air great, and offer a good ride.
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.

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

I was not all that impressed with this tire, I do see a radial offering available now and would recommend it over the bias ply.
