This tire-and-wheel combo is built for real towing conditions. The Loadstar ST175/80D13 bias tire carries up to 1,360 lbs at 50 psi and is rated for 81 mph (speed rating M). The matching 13" x 4-1/2" steel wheel supports up to 1,660 lbs and meets Department of Transportation specs, so you can count on dependable performance mile after mile.
The bias construction uses thick nylon cords set at a 30- to 45-degree angle in alternating layers, giving the sidewalls the stiffness needed to handle uneven surfaces without flexing excessively. The advanced rubber compound improves tread wear and lowers rolling resistance for a smoother, more stable experience both on and off paved roads.
Rust doesn’t stand a chance against the dual-layer protection on this steel wheel. An e-coat primer seals the metal against moisture, then a white powder coat adds a clean look and long-term corrosion resistance. It keeps its finish sharp even after repeated exposure to water or road grime.
This assembly comes pre-mounted and aired to proper pressure, so it’s ready to install right away. That saves setup time and ensures even seating on the rim for a solid, balanced ride right from the start. The combination of the Loadstar tire’s flatter tread profile and bias construction delivers excellent stability under load without harshness over bumps.
With a standard 5 on 4-1/2 bolt pattern, zero offset, and a 3.19" pilot diameter, this wheel mounts easily on many trailer hubs. Wheel bolt size is 1/2"-20, making it simple to torque down securely to the recommended 75–85 ft-lbs before your first trip.
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"

Delivered quickly & in fine shape. The tires & rims are just like pictured on the web page . Brand spanking new!! Thanks.
Great OEM replacement for tire punctured beyond repair.
Initial review-outstanding service, quick, free shipping, perfect fit. We upgraded our old 12" tires on our tent trailer with these. Added 2" to height off ground.
Completely satisfied with my tire purchase! Already put 3000 miles on them and still look like new. From the ordering to delivery the whole experience was excellent.
Placing the order was easy. Then I received a message that my order was delayed but there was another similar item in stock and eve cheaper! My order was delivered quickly, accurately and was a great value. Strainer will be my first online stop from now on.
Exactly as described these were a direct replacement for the ones I had on my trailer. Work good my last pair last 10 years and are still going. They will be used as spares now.
My Wheel Assemblies Cam Fast, Packed Great And Everything Looked And Fit Properly!! The Tire Air Pressures Were Even Exactly What They Were Suppossed To Be:) Thank You VERY MUCH Etrailer, Very Happy With My Purchase!!!!!!!
The products I ordered are of the best quality and fit my application perfectly. As happy as I am about the parts, the Customer Service is what made my experience with etrailer so enjoyable. They worked with me to find me the right parts and were courteous and professional through the whole process. Thanks etrailer, you made a new lifetime customer. I will be singing your praises to everyone!
Couldn't beat the price, great website, many options, fast shipping, excellent communication and updates. E Trailers is doint it right and free shipping over 99, heavy hubs and large tires at my door for free!
Tire came quickly with updates through to delivery. It has been a pleasure buying from etrailer.com. The tire came exactly as ordered and shipped in a box instead of just slapping a sticker on the side as I have seen before. I will definately buy from etrailer again.
So far... no complaints. Needed a spare tire with rim for my utility trailer. Found this site and had no problem getting what I needed with free 2 day shipping. Awesome. I will make this site my go to site for my utility trailer.
I have yet to install the product on my trailer, however it looks correct. The service of etrailer was fantastic. The quick shipping was great, the tire arrived a day earlier then the website said, couldnt be happier.
Tires were delivered sooner than expected and boxed together, with no shipping damage. Date on tires is only a few of weeks old. What GREAT service and answered every question to my total satisfaction. I will definitely use E Trailer again . Thanks for the treating me like a real customer and not just an order #.
These tires are great. They function as expected and fit my budget. My old tires were original for the trailer and were still operational after 20 years of light use. When these tires are still functional after 19 more years of light use, this review can be updated to a 5 star review.
Nice tires and rims fast shipping
Again super fast shipping. Thank you for being a company that can be trusted and you back up what you say. When I need something else I will be back. The tire and rim are just what I wanted.
Perfect replacement for the original wheels and tires on my Worthington aluminum trailer. Fit was correct, and the powder coated white with red/blue pinstripes really spruces up the trailer.
