This tire is ready to work. The Loadstar ST175/80D13 Bias Trailer Tire carries up to 1,360 lbs at 50 psi and meets Department of Transportation standards. It’s built with sturdy sidewalls that handle heavy loads without squirm or sway, giving you confident tracking on the road. The flatter tread profile keeps things stable and predictable when you’re fully loaded.
The bias ply design uses tough nylon cords set at a 30–45° angle in alternating layers. That crisscross pattern makes the sidewalls stiffer so the whole tire flexes evenly over bumps and uneven ground. You get solid handling and a smoother pull when trailering off pavement or across rough lots.
A high-quality rubber compound helps this tire wear longer and run cooler. The low rolling resistance design means less heat buildup during long hauls, smoother motion behind your tow vehicle, and better overall efficiency mile after mile.
The Loadstar ST175/80D13 comes with a 1-year worry-free guarantee—if it’s damaged for any reason within the first 12 months, it’s replaced at no charge. That kind of backup gives extra confidence when you’re covering serious ground or hauling heavy gear season after season.
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
Good rubber and holding up well with limited use. Made in China, so i'm awaiting the longetivity test
Just a tire. Hasn't let me down yet, so it must be good. My feeling is that its the best tire in its class.
Tires did what I needed them to do. I did have them balanced as it made all four roll with no vibration. I recommend the balancing. It made all the difference.
Excellent customer service
Great customer service and fast delivery
Got my tires. They look in good shape being new. Delivery was prompt and ordering was easy enough. Reputable dealer.
Great service, fast delivery! Doesnt get much better! Thanks etrailer!
Accurate, timely, professional service from etrailer.com
Fairly good set of tires for my boat trailer. The previous set wore funny but that was after 8 years of use.
I haven’t installed my lights and tires yet but I couldn’t wait. Based on customer service and timely delivery alone, Hanna, Carol and George, awesome! Thank you!
I purchased two trailer tires. Ordering process was easy, product received when promised.
Tires are a great replacement on my 2000 loadrite tandem trailer. Perfectly satisfied going into my 2nd season.
I’m very satisfied with the overall quality of the loadstar tire it lasted 5 years before needing replacement
I’ve used these tires for about 4000 miles over the past year on my motorcycle trailer. Stable, good tread wear.
I have ordered two of these in separate orders. The tires look good and were very well packaged. They arrived very quickly. They are identical replacements for those on a boat trailer I bought 9 years ago. They did wear funny. One was worn in the middle and the other on the outer edges. Don’t know why. Both were inflated to 50 psi as is indicated on the trailer placard. I can’t complain though. They had lots of hard use.
I put these on my enclosed trailer, no bounce and both are wearing evenly, great tires
Just received an email from Katherine at etrailer stating that UPS delivered my package and it was on the front porch. Sure enough, there it was and I couldn't be more pleased. Haven't had an opportunity to install the tires or brake controller but etrailer directed me to a page that has great information about both products. Nice job folks and I will definitely purchase from you again. I paid with PayPal and it couldn't have been easier. Thanks again, Jim M.
All I can say is wow, ordered new trailer tires and they arrived two days later. The new tires are date coded 2819 and 4619 so both are less than a year old, which is great. The old tires were almost 18 years old and though they still looked good I didn’t want to take a chance on a 2500 mile round trip to Daytona with the motorcycle on back. I already mounted them and serviced the trailer, so I’m ready to roll. Loadstar 175/80 D13 LRC.
Thank you for making it easy and quick enough for me. The tires and wheel are just what I ordered and needed for my trailer. Look forward to ordering from you'll in the future. You were recommend by a friend.
Ordered 2 new Kenda tires for my popup camper, using website to order was quite easy and delivery was as promised. Will do busines with etrailer again in the future. Camper had the original Kenda tires and they kasted 15 years with alot of use.
Have had these tires for a year now. Replaced tires on my trailer and hauled my winter supply of wood pellets with great results!! Thanks e-trailer
I gave them a poor rating before but have change my rating. They originally sent me the wrong item, but they were very helpful in sending the item back and a week later I had the correct item in good shape. Everyone was very pleasant and helpful that I talked to. They also priced matched my items.

Tires are great. Boat tracks extremely well at highway speeds.
Exact match for my trailer spare. Great price and service, fast shipping. Will use eTrailer again I'm sure.

Trailer tires are working great on long trips.
Shipment was quick and just what I ordered. They match the spare I already had on my boat trailer. Had them mounted locally and now trailer is rolling as good as new.
I am happy with my purchase.

So Far so good... seem to be holding up fine
Super fast shipping and good phone help as per etrailer!
Tire tech had some problem getting one of the tires
mounted due to its being compressed for shipping
purposes. Maybe a note should be added in listing about this issue
or video of technique used to assist the tire tech.
Thanks
