This setup is built for miles. The Loadstar ST185/80D13 bias tire carries a Load Range D rating with an 8-ply construction and a 1,710-lb max load at 65 psi. It’s rated for M speed (81 mph) and meets Department of Transportation specs. That’s solid confidence for highway towing and long trips when you need reliable performance under load.
The 13" x 4-1/2" steel modular wheel uses an e-coat primer and white powder coat to hold off rust and corrosion. That triple-layer finish keeps the wheel looking clean and solid even after seasons of use around water or road grime. The improved torque retention design also helps keep the wheel secure over time.
The Loadstar special trailer tire features a flatter tread profile for stability and better handling. Its advanced rubber compound delivers longer tread life with lower rolling resistance, which means the tire tracks straight and runs cooler at speed. The result is a smooth, confident feel mile after mile.
No extra steps needed—this combo arrives already mounted and inflated to proper pressure. The matching 5 on 4-1/2" bolt pattern, 0 offset, and 3.19" pilot diameter make it easy to bolt on and hit the road without extra shop time. It’s a simple upgrade that saves time while giving your trailer a refreshed, dependable setup.
Bias construction uses durable nylon cords set at a 30–45° angle in alternating layers, giving the sidewalls extra stiffness so the whole tire flexes evenly over rough ground. That design brings stability and control when running over uneven surfaces or backing into tight spots, backed by Kenda’s 5-year tire warranty and limited 1-year wheel warranty.
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"

Ratings & Reviews
Tires and wheels are performing fantastic! Great value , I highly recommend this purchase
Needed two 13inch tires for my RV trailer and shopped for the best price and delivery options. I predicted it would be another site or big box store but etrailer was the best deal and delivery. Real happy with them.
I appreciated that the tires arrived (early) inflated & ready to mount. I just now put them on my box trailer, so I can't speak to quality or wear yet, but they look nice and sturdy when compared with the 6-ply (load C) tires they replaced. If they prove themselves, I will add a fifth star to my review.
Looked high and low for a 13" 8 ply rated tired for my camper. etrailer offered a fair price and lightning fast shipping!
Great service and very helpful in getting correct part, Corey J was very helpful and friendly . Will use this company next time I need parts for my camper , could not find needed parts locally.
Thank you.
Haven't road tested the tires/wheels yet (middle of Winter) but the ordering process was seamless and delivery prompt! Items delivered are exactly what was ordered. etrailer website was very helpful in selecting the correct stud pattern for the wheels. Very satisfied.
Delivery on time and fitments perfecr
Recently I ordered a wheel and Tire for our camper as a spare and time was the essence as we were leaving shortly. Having delt with etrailer before I knew they would not let me down . There was a small glitch but etrailer notified me of what had happened. Two days later wheel and tire was delivered to our house . Thankyou to the staff involved , George and Amy, for keeping me up dated . I give etrailer five stars for great service , specially in these trying times .
Exactly what i was looking for. Ordered Sunday afternoon and order was at the door on Tues (No shipping $ to boot!). Put them on the trailer and hit the road on Friday. Absolutely no issues :-) I would highly recommend etrailer to anyone.
Exactly what I wanted. It was back ordered but well worth the money. Etrailer is awesome.

Great!
So in the process of finding wheels that were in stock, my first choice was not in stock; it seems that I moved from a 13" wheel to a 14". Nice wheels & tires but I am forced to reposition the fenders which I was not excited to do.
Shipping was very fast and the tires/wheels were packed very securely. The only reason that I didn't rate the transaction excellent was because the valve stems installed on the wheels were different. One was a combination rubber base and metal stem and the other was the traditional rubber. A trivial issue to say the least. Just consider it constructive criticism. I will definitely not hesitate to visit etrailer the next time I am in the market for trailer supplies. Great vendor.
Tires, wheels, drums, and brakes are law excellent. Tires wear better than previous pair.
etrailer products always meet my needs.
Great trailer tires and easy way to improve load rating on my trailer. The trailer itself was rated much higher than the tires so that limited the capacity and the new mower I got was right at the edge. Rather than get a new trailer I upgraded the tires for additional peace if mind and safety.
While I havent had a chance to use my Popup camper as much as I like (especially this year), I have had no issues at all with the Kenda Loadstars after having a flat on almost every trip before I got these tires. They came packaged very nicely and Etrailer has been a pleasure to deal with on this and other purchases.
Doing well on a palomino 4103 pop-up
I bought a st185d13 tire and wheel and they came super fast and are a very good product. This is the second time buying from e trailer and will not be the last.

Hello,These loadstar tires and rims are holding up very well.I have them on my camper that gets used very often,just got back from a 6300 mile road trip from Florida to Montana and back and I did not have one problem with these tires. You can not even tell any tread loss at all and the rims are very true.I give these tires and rims a 5 star rating!!!!! P.S. the brakes that I bought from Etrailer for my camper are also very good quality and held up to all of my road trips.
Wheels and tires fit perfectly on my Interstate Loadrunner Cargo trailer. Performance is very good.

All still good and working as intended.
I try to buy everything locally but buying from Etrailer I saved $100 over buying locally for 2 wheels and tires. The whole order from purchasing online to installing on my trailer was quick and flawless.

Used the tires on a fishing boat and fished almost daily until ice on the lake. They work perfectly have not had to add air yet and they travel the road great.
Hey thanks etrailer. Once again great products fast shipping and great customer service you all are the only place that sends me constant update on the shipping process. The spare tire and minting bracket work great.

This tire and wheel set has bailed me out already this boating season. Works as it should.
The reps at etrailer.com are quick to respond to questions even by email. The tire and wheel assemblies arrived in one box in perfect condition. The order arrived in a timely manner. The wheels are as indicated on the website. The tires are black and round. I would not hesitate to reorder anything from etrailer.com

We have put appx 700 miles on these tire and wheel combos. No issues tires are still black and round all is well. Thanks etrailer.com Well done.
I received my tires as scheduled. I was happy to see that were boxed,unlike another online company that I have bought tires through.
I was also pleased that they were only 3 months old as age is very important for trailer tires.
The UPS tracking was a bit sketchy. They moved twice in 2 days and then disappeared for a week only to show up again as "on truck for delivery" on the delivery day. Not a big deal, but in this age of mile by mile tracking, it was a bit disconcerting.
My experience with etrailer was all in all easy,positive and uneventful. What more can a person ask? This is my 3rd order for etrailer and I will not hesitate to order again!

I am very happy with these tires.We put them on our travel trailer. 17,000 miles in 103 days. Interstates city streets,forest service BLM roads and occasionally no road at all. Dragged them across a couple of curbs, no problem at all. I would recommend these tire for any one with this application. They ride a bit harder than radials, but that is to be expected.
A tire is a tire.
I will start with this purchase was a fantastic experience from start to finish!!! Easy website to navigate, super fast shipping, great packaging, tires showed up individually boxed and in perfect condition!!! Bolted right on and away I went!!! Thank you for being a great seller!!! I will definitely be a returning customer and will be recommending you to anyone I know!!! Oh, tracking info was on point as well!!!!
Our tire blew on our trailer on a Monday. I easily found the exact tire and rim at a great cost from etrailer that evening and it was expected to be delivered that Thursday. I was very skeptical about it being delivered that fast, but with an expected delivery time between 2-6pm, it was delivered to my porch at exactly 2pm. The product was exactly what we expected and a high quality. We are taking the boat on a trip, so needing to replace the spare was a must, especially after our last mishap. I woul highly recommend etrailer to anyone! I was overly impressed with the entire process and the product!
