Radial tire has a 10-ply rating and a 3,197-lb max load at 90 psi. Hub-piloted steel wheel has an 8 on 6.5 bolt pattern and a 4.77" offset. Can be either the inner or outer wheel of a dual-wheel setup on your trailer.

Specs:
This tire has a 1-year worry-free guarantee. If within the first 12 months the tire is damaged in any way, it will be replaced at no charge.
This tire-and-wheel assembly is designed to be used in dual-wheel setups. The 5.35" offset allows the wheel to be positioned closer to the trailer frame when used as the inner wheel of the setup. And if you use this assembly as the outer tire and wheel, the offset ensures that it will sit closer to the outside of your trailer. This hub-piloted wheel centers on the hub, not the lugs, and it requires the use of flange nuts (sold separately) for installation.
Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.
Determining the Bolt Pattern
The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.
To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)
On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)
Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

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.
