When you’re logging miles in the heat or hauling heavy, this tire and wheel combo is built for confidence. The Loadstar ST185/80D13 bias tire has an 8-ply rating and a maximum load of 1,710 lbs at 65 psi, backed by a speed rating of M (81 mph). The matched steel wheel handles 1,660 lbs, and the whole assembly meets Department of Transportation specs for safe highway performance on long-distance runs.
Corrosion doesn’t stand a chance. The 13" x 4-1/2" Dexstar steel wheel uses an e-coat base topped with a white powder coat finish that seals out moisture and road grime. It resists rust even after seasons of use and keeps its clean, polished look through wet weather, humid climates, and storage outdoors.
This bias tire uses nylon cords set at a 30- to 45-degree angle in alternating layers, giving it a strong sidewall that flexes as one piece over uneven ground. The result is predictable handling and a steady ride when pulling across rough surfaces or transitioning from pavement to dirt. It’s durable design that feels surefooted wherever you tow.
No need to mess with mounting or shop fees—this tire comes already installed on the wheel and aired to proper pressure. Just bolt it on and go. Owners like that it saves setup time while still delivering a balanced, smooth towing feel right from the start.
The steel wheel features a 5 on 4-1/2" bolt pattern, a 3.19" pilot diameter, and a 0 offset for easy fitment with common hub setups. Wheel bolts are 1/2"-20, so you know exactly what you’re working with when lining up your replacement or spare setup.
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
To prepare for our move from Louisiana to Ohio, we purchased 5 of these tires (inc. 1 spare). It truly made a difference. Here we are one year later and still satisfied. I would recommend them to anyone!
You had the product I needed and delivered it especially fast.
Etrailer was very fast at shipping tire/rim assembly. These come to you not balanced as expected. Local tire dealer did the balance and I installed. They now have approx. 2k miles with no issuses to date. As soon as possible the RV that these are mounted on will be heading out for a 5-6k road trip and that will be the true test of how they will hold up. I see no issuses with this set so long as I do my part, keep air pressure up, torque lugs at each gas fill and insure bearing are good and lubed.
The service from etrailer.com is topnotch. Everything arrived at my front door BEFORE I was expecting it. The product was as described online. I had the tires and wheels balanced before I mounted them on my pop-up. I've only put about 1900 miles on them, but have noticed no problems whatsoever. I would not hesitate to recommend etrailer.com.
Ordered these tires with wheels, mounted them on our camper and headed to Kansas, a 1000 plus mile round trip. They performed flawlessly, very happy with them.

We havent had our camper out for over a year, but when we decide to hit the road I know our tires will do the job. Thanks for checking on them
Great tire, and great transaction through E trailer. Thank you very much.
Easy to use website; helpful product review videos; good ordering experience; very good price on tires - found some slightly cheaper on- line, but shipping ate up any savings. All in all, etrailer is a straightforward, customer friendly, quality company.

I had one long trip with the trailer hauling a UTV to the mountains in Colorado right after purchasing them. The tires performed as hoped with no problems. Though the trailer had not been used heavily since, I continue to have no problems. I still highly recommend ETRAILER.
This is a great tire for my heavy duty application of a Coleman Bayside tent trailer. Etrailer delivered for me over night when I had to use my spare and I still had quite a distance to travel. Since it was late in the day the customer Service Rep Erika made sure the order went to the warehouse and it made it out for overnight delivery.

You got me out of a big problem with that tire, and for that I thank you immensely. There are not a lot of sources for that wheel and tire, and the Coleman Bayside was so heavy it needed this tire. We have since sold that trailer, so I cannot comment, but I am sure it is doing fine. Thanks again
13" trailer tires. I needed to lower my trailer bed, but was worried about a smaller tire not having enough load capacity. I found these, load range D, with nearly the same capacity as my 15" tires. Good price, quick delivery.

They have worked very well. I may go back to a larger tire and wheel. I’m sure you have deals.
The tires on rims arrived exactly as stated. Good fit on the new axle. The customer service was very helpful. Highly recommended.
Great tires. I was able to standardize on all my trailers. Duck boat, Walleye boat and utility trailer all the same tires now.
Just Put The Products On The Trailer, The Rims And Tires Look Really Good, Haven't Had A Chance To Use Them Yet, But Better Than I Expected And Had on The Boat Trailer, I'm Impressed! Will Let You Know How They Travel Down The Road!
The tires arrived today and I could not be happier !!!! From order to delivery the service was great. I was a but concerned because I have never ordered tire over the web and thought they might be scuffed or scratched when they arrived. I was wrong they are in perfect condition and look great on the camper.
I have less than 100 miles on these tires so I really can't say it is a 5-star item. It sure looks the part in person. I haven't had any indication that they are out of round or have sidewall issues. Although I have few miles on these tires, I made the same purchase for the next project's needs. I will also be purchasing another two for spares.
Epic ordering on these and super fast protected shipment!
I replaced my tires and wheels using a full set of four of these. It cleans up the look of my aged trailer and i feel safer. I could not be happier. Thanks to etrailer.com for the quick shipment.
Quality product at a great price. Installed the rims and tires which took about 5 to 10 minutes per side. Towed the trailer with my SeaRay 180BR over 600 miles last weekend and had no issues with the tires and rims. The tires and rims came in less than a week from when I ordered, so overall I am very happy with my purchase.
Ordered Westlake Pop-up camper tires with rims. Arrived exactly on time! Easy ordering, detailed description and wheels & rims look great on our pop-up. Thanks etrailer!
My pop up trailer needed new tires, and I couldn’t find any locally (not at the camper store, not at Walmart, not at Tires Plus). I easily found what I was looking for on this website and ordered two tires. They came quickly. Unfortunately, I bought the wrong ones (read the manual wrong). Return was easy and I got my new tires quickly. Yay! I would definitely do this again—super easy.
I want to thank you for excellent service -- I could not ask for better. Your web site was easy to use and to order from. I received a quick confirmation of the order, which even seemed personalized confirmation of shipping. And then it arrived 3-4 days earlier than I would have expected. And it was the right product, right size, right mount. And it was all done in about 15 minutes for me- saved me driving time, gas costs, and having to special order unstocked merchandise locally-- less expensive when all those factored in. I'm delighted.
Thank you, etrailer for stocking this size wheel and tire. I've looked everywhere and couldn't find it. It's a great quality wheel and great tire. It looks good on my pop up. Also need to thank etrailer for a great experience. When my tire arrived, it had been mislabeled at the warehouse and was a different side than what I ordered. I called etrailer and they exchanged it hassle free. I will definitely use etrailer again when I need camper parts. Oh, and the price was great!
Finally had an opportunity to use the trailer with the new tires. They performed flawlessly which one would expect after buying new tires. I actually bought a higher rated tire then I needed just for my own reasons, Haven't noticed any ride difference as far as a harder or stiffer ride. Put over 500 miles on 'em the first time out. Very happy with these.

As a follow up tires are still performing great. No issues. We tow a 2900 pound pop up all over the place, Normal run for us would be about 300 miles give or take. Tires and rims have been awesome.
For the price of these new wheels and tires it’s hard to justify pulling a camper to a tire shop and leaving it to get new tires; I ordered a set of four from etrailer and they came in a few days later; I got new tires “and wheels” and didn’t have to take my camper somewhere to get it done; also by doing this I was able to save my best looking tire for a spare and take the three used wheels and tires to scrap for cash! I also saved another used one to use as a spare for my utility trailer.
Fast del and always great looking wheels can’t wait to mount them and have no worries going forward
Awesome selection and fast shipping. Service reached out after order! Very happy with this purchase. Put tires on today and look great and no problems.
