When you’re carrying serious weight over long distances, this tire-and-wheel setup is built to handle it. The Karrier ST235/80R16 radial tire has a 10-ply rating and supports up to 3,197 lbs at 90 psi (dual tires). It’s paired with a steel wheel rated for 3,860 lbs and meets Department of Transportation specs. The radial construction keeps rolling resistance and heat buildup low so it stays stable across miles of highway travel.
Moisture, road salt, and grime don’t stand a chance against this wheel’s finish. The heavy-duty steel rim uses an e-coat primer topped with a silver powder coat for strong corrosion resistance. It keeps its clean look and integrity through wet roads and long-term use, season after season.
This assembly’s ±5.35" offset makes it easy to use as either the inner or outer wheel in a dual setup. The hub-piloted design centers on the hub for a sure fit and requires flange nuts (sold separately) for installation. It’s a versatile option that simplifies matching pairs without compromising stability or spacing.
The radial ply design positions cords at a 90-degree angle to the direction of travel, reducing internal friction and heat. That means smoother highway tracking, less tread wear, and reliable traction in wet or dry conditions. Double steel belts and full nylon plies combine for long life and confident handling mile after mile.
If the tire is damaged within the first 12 months, it’s replaced at no charge under Kenda’s 1-year worry-free guarantee. The wheel carries a 2-year limited warranty and the tire a 5-year limited warranty, giving you solid peace of mind with every haul.
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"

Hi, everybody, Andy here with etrailer.com. Let's take a look together at this Karrier ST23580R16 load range E radial trailer tire with this 16-inch silver steel dual wheel. Now, this special trailer tire, or ST tire, has sturdy sidewall so it can handle heavy loads. It is created specifically for trailers and not intended for use on other vehicles. As you know, radial ply tires are designed for trailers that are towed on the highway. Now, this radial tire is constructed with double steel belts and full nylon plys that combine for superior function and long tire life.
This computer-generated tread design and premium rubber compound materials are gonna give you traction, superior traction in wet or dry conditions. So as I stated, just a moment ago and as we have stamped on our tire here, this is an ST23580R16. The section width is 9.4 inches and the outer diameter is 30.9 inches. This is a load range E, meaning it has a 10-ply rating. The maximum load single is 3,500 pounds at 90 psi and the maximum load dual is 3,197 pounds at 90 psi.
This has a speed rating of M, indicating a maximum speed of 81 miles per hour. This heavy duty silver steel wheel with one, two, three, four hand holes, it is designed to be used in dual wheel setups. Now, this wheel does have a high offset, so it does allow for the wheel to be used as either an inner wheel and you would set it in this orientation as a inner wheel or an outer wheel in this orientation on a dual wheel setup. And the offset is either a positive or negative 5.35 inches. This steel wheel is sturdy and corrosion-resistant.
It does feature, as you can see, a silver powder-coat finish and it's over an eco-primer. Now, this is a hub-piloted wheel, which means it will center on the hub of the axle, not on the lugs. The pilot hole diameter is 4.77 inches, and this does require the use of flange nuts for installation. We do sell those separately here at etrailer.com. And this does use a wheel lug size of 5/8 of an inch by 18 flange nut.
As you can see here, we do have a metal valve stem that's already installed in the wheel. The dimensions of this wheel, measuring bead seat to bead seat is 16 inches in diameter. The width, again, measuring bead seat to bead seat is six inches wide. This wheel has a capacity of 3,860 pounds. The bolt pattern is 8 on 6.5 inches. And in case you don't know, the first number in the bolt pattern is the number of bolt holes. The second number is the diameter in inches of the circle on which the bolt holes sit. So to determine the bolt circle diameter on wheels with an even number of bolt holes as we have here, you're simply going to measure from the center of one bolt hole to the center of the bolt hole directly across from it. This assembly does meet the Department of Transportation specifications. And I think that's gonna wrap up our a real quick look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.
