When you’re towing at highway speeds or making long trips in the heat, this tire-and-wheel setup is ready to go the distance. The Loadstar ST175/80D13 bias tire carries 1,100 lbs at 35 psi with an M speed rating of 81 mph, paired with a steel wheel rated for 1,360 lbs. The combination meets Department of Transportation specs for safe, confident performance mile after mile.
No need to visit a shop just to get rolling. This assembly comes pre-mounted and aired to proper pressure so it’s ready to bolt on and go. It saves time, eliminates mounting hassle, and delivers a balanced ride that feels stable from the start.
Bias ply design uses thick nylon cords set at a 30- to 45-degree angle in alternating layers for a tough, flexible structure. The sidewalls work together to absorb bumps and uneven surfaces, giving smoother handling when trailering over rough ground or gravel. The advanced rubber compound also helps reduce rolling resistance for an easier tow.
Saltwater, rain, or road grime won’t eat away at this wheel. The 13" diameter x 4-1/2" wide steel wheel is galvanized for strong corrosion resistance that holds up in humid or marine environments. Its 8-spoke design looks clean and stays durable through seasons of use.
Fitment is straightforward with this setup. It uses a 4 on 4" bolt pattern, a 2.65" pilot diameter, and a 0 offset so the mounting surface lines up directly with the wheel’s centerline. Section width measures 6.6" with a 24" overall diameter, giving clear specs for proper clearance and fit on your trailer build or upgrade project.
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"

Product is exactly as described for a great price. Ordering and checking out were simple. I was kept upto date on my product and shipping details. Was an overall good experience and I look forward to doing business with you again. Thank you
These are a much needed upgrade for a Hazardous Fraught trailer I, using as a kayak hauler camping trailer. I haul it from Kansas City to Denver once a year for to our annual Fish Camp. I'll update the tires performance here in two weeks when I return. For now they appear to be quality.
Efficient, knowledgeable, and helpful, I've used etrailer for 2 towbars and now wheels and they are a great company to deal with.
I am so pleased-first you had the tires And rims for my trailer that I needed but I had not been able to find locally. I had a 6 day deadline that I needed them by and after talking with Justin he suggested the the 3 day expedited delivery plan. I ordered them on a Thursday afternoon and Justin thought maybe we had passed the shipping deadline for that day. Not so- they shipped on Thursday and they were delivered today, Saturday. Great service!
This tire and wheel is as advertised.
It is a spare for my very old boat trailer - to limp me home on surface streets if get a flat.
Doing its job fine.
GOOD QUALITY TIRE. nice looking wheel for my trailer with tires rated to 81 mph so I can safely take my trailer on the highway. They arrived in 3 days to Michigan so I was very happy. I had the tires and wheels balanced after they arrived.
Great product!
These tires and wheels are in use every day on my honey bee trailer. Great product and recommend them to anyone who wants tires for their trailers.
Showed up quickly and still going strong a year later. Nothing fancy but just what I needed for an old fishing boat trailer. Once I put these on I found out I also needed to replace the springs and axle mount as well!
Great fit, fully inflated, road ready!
I would never purchase this model of tire again. First trip, less than 350 miles on tires, the left one blew out completely (a very large rip about a foot long). The total trailer weight for this maiden trip was only 500 lbs, so only 250 lbs load on the tire.
Also, I was surprised by the tread pattern. Looked nothing like a road trailer tire or even a car road tire that I have used. Looked more for off-road, yet with without thick nobbies.
I'm anticipating some small partial warranty refund, but after paying tire disposal fees, and realizing the matching tire is not to be trusted; I'll be out about $[XX] bucks. I didn't expect this from an etrailer purchase. Granted etrailer's customer service is quick & polite, but I'm still out $[XX].
Tire arrived flat. I inflated to proper pressure and within a couple days it was flat again. Note, these tires were never used and the trailer I installed them on never left the garage. So, zero mileage on the tires. I. Called your phone number listed only to be told I had to go to the tire Manufacture to figure out how to return the tire, if they would even allow me to. So if you want to deal with this company and take your chance on any sort of customer service you are in the right spot. I’ll take my future business elsewhere.
Always have what i need , and quick shi pping
Product was delivered in a very timely manner. It’s nice to have a spare tire the correct size
Haven't installed yet but looks perfect and hats off to the poor Ups guy carrying box on his head up driveway.

I'm glad UPS made sure to get these to you safe and sound, and that they look perfect Michael! Feel free to let us know how install goes once you get the chance to put them on.
Wheel was not balanced, made the whole trailer shake, had to have that done, along with two other wheels purchased from etrailer. The tire place showed me a weld on the rim that was definitely not done by a professional, they recommended only using that wheel as a spare only. The other two wheels were in good shape, just badly out of balance.

Typically trailer tires will not come balanced like vehicle tires are. They are meant just to support the trailer load versus providing a smooth ride for people. You can have the trailer tires balanced. Just remember that many trailer wheels are centered by the position of the lug bolts [these wheels are lug-centric] and not the center bore of the wheel. For best results, have them balanced using a pin plate adapter. This mimics the way a lug-centric wheel is mounted to a hub.
Ordering was simple and easy enough, I ordered the wheels (galvanized rims) and new tires. The web site showed me how to tell my wheel size, received and installed both on my trailer in a few minutes each side. Price was great and a name brand quality that I was looking for . I highly recommend e trailer! South Florida boat trailer salt water

Most excellent! Still happy with my purchases
I ordered 2 replacements tires for my boat trailer. I decided to get rims as well since I needed a spare and with the cost of mounting tires, I figured to break even selling the other original as a spare.
My initial impression of the rims and tires is great. In fact, I was even surprised as I expected some tires off a shelf with a layer of accumulated dust. Not the case at all. These were clean and shiny with not even a scuff. I ordered 2 and they were shipped in a box! Frankly, I was impressed and I don't impress easily.
Shipping was UPS and tracking was accurate. Product arrived on time.
I also want to add that I appreciate the short hold times and informed staff at etrailer. They proved very helpful on my purchase.
Very pleased with these tires.

I have put quite a few miles on these tires and they have held up very well. Very pleased with my purchase and if I had the chance, would buy them again from etrailer.
Appears to be of good quality. Unfortunately no paperwork as to warranty and recommended tire pressures. Now I can travel faster than 45 mph! Lol.
Good looking wheels and tires.. making a kayak trailer from an old boat trailer with a 4 lug axle.. these are just a fit and a good replacement for old 12” wheels
This tire and wheel combo was a great purchase. etrailer was great to deal with and very prompt with any follow up or questions.
Bought these to replace the small 12in wheels that came with my trailer, and I've been extremely happy with them so far. They look great, added nice clearance for my trailer, and increased the speed rating to allow me to comfortably travel at highway speeds. I've made two long trips with the trailer since I bought these (350+ miles), and was very happy with the performance on the road. Visually, I feel these wheels/ tires have improved the look of my trailer also, so that's a nice plus as well. Would definitely recommend these wheels/ tires.
