This tire-and-wheel combo is built for steady towing at highway speeds. The Loadstar ST175/80D13 bias tire carries up to 1,360 lbs at 50 psi and has an M speed rating for 81 mph. It’s matched to a steel wheel rated for 1,660 lbs, so you’ve got plenty of capacity margin when you’re loaded up. Both components meet DOT specifications, giving you dependable performance on every trip.
No need to make a stop at the tire shop—this comes mounted and aired up right out of the box. That means you can bolt it on and get rolling without extra setup time or cost. The balanced feel on the road keeps things smooth, making it an easy upgrade when you just want something that works right away.
The 13" x 4-1/2" steel wheel is dipped in molten zinc for a true galvanized finish that stands up to water, salt, and humidity. It’s built to resist rust for the long haul, staying solid and functional in marine or damp environments where uncoated wheels would fade fast.
This tire uses a six-ply bias construction with nylon cords laid at alternating 30- to 45-degree angles. That design stiffens the sidewalls so the whole tire flexes evenly over bumps and uneven ground. The result is better stability and a smoother feel when trailering in real conditions.
The wheel has a standard 4 on 4" bolt pattern, a 2.65" pilot diameter, and a zero offset that centers the load squarely over your hub. Wheel bolts are 1/2"-20, making it an easy match for common setups without guesswork or modification.
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"

Changed the boat trailer into a flat bed trailer. The new tires and wheels makes it look very nice.
Very nice wheels and tires, perfect fit for my trailer. Shipped fast
These are heavy duty 6 ply tires they work perfectly ,thank you.
Got three tires with rim assemblies. They were packaged well and look good. After getting them on my boat trailer (one is a spare), I checked the date code. They were produced Jan 2023. Tires should be replaced for wear as well for age.
I am extremely disappointed with etrailer for passing off year and a half old tires as new. Especially as there was a two month delay from the order date to what they claim was “out of stock” and waiting two months for delivery.
PERFECT, MAKES MY OLD TRAILER LOOK LIKE A PIG WITH LIPSTICK
Awesome price and fast shipping!
Perfect for my trailer
Fast response and shipping
Will be ordering again soon for my boat trailer
Tires are the right size but the rims a ren't
Very fast shipping and excellent product. Trailer needed new rubber and getting these tires with new wheels made the change over easy.
good vaue for a small trailer
Fast service is all I can say if you want this type service then buy from etrailer
Quality item, packing for shipping was great
I’ll buy again
Thanks for your follow-up. Attached is a photo of the new wheels/tires mounted on my trailer. The 35+ year old girl hasn't looked that good in a long time. Can't wait to tow something and not have to pump air in the leaking rims before hitting the road. Thanks for the excellent product line and fast service.

The Kenda tires are not working out as expected. One has developed a slow leak, with no obvious damage to the tire, such as nail or puncture. I havent had a chance to water tank test it to see if the problem is the valve, bead, wheel, or tire.Have you had any other similar problems reported with Kenda tires that would indicate where to focus?

Arrived fast well packaged and tire wheel assembly looks great.
Excellent service Quick shipping
Just put 500mi on a trip with the new tires. They tracked great didn’t overheat at all. Much safer than the recommended oem. Great buy! Quick shipping.
Love the tires and how they look on the galvanized wheels. I did find small blotches of galvanized residue on the back of each rim. I will be using these new tires to replace my current 12" rims on my kayak twin kayak trailer. Can wait to try them out.

Glad to hear you love the look of the tires and galvanized wheels! We appreciate you pointing out the small, galvanized residue spots on the back of the rims. Those can occasionally occur during the galvanizing process, but we’re happy to hear you’re excited to get them mounted on your kayak trailer. Hope they work great for your adventures on the water!
