When you’re pulling serious weight, this tire-and-wheel combo is built to handle it. The Triangle ST235/80R16 radial tire carries a 4,080-lb maximum load at 110 psi and is rated for 75 mph (speed rating L). The 16" x 6" steel dual wheel is rated at 3,860 lbs, giving you the confidence to haul mile after mile with balanced support. Both meet DOT specifications for safe, reliable performance on the highway.
This tire couples the strength of a bias design with the durability and stability of a radial. Its all-steel belts enhance tread life, while the computer-generated tread pattern and premium rubber compound provide solid traction in wet or dry conditions. That rugged 14-ply build keeps its shape under load and resists heat buildup, so the tread lasts longer even on demanding hauls.
Moisture, salt, and road grime don’t stand much of a chance here. The dual wheel’s e-coat primer and black powder coat finish provide corrosion resistance that holds up over time. It not only protects the steel from rust but keeps the setup looking clean after seasons of use.
Unexpected damage can happen anywhere, but this setup has you covered. If the tire is damaged within the first 12 months, it will be replaced at no charge under the included 1-Year Worry-Free Guarantee. That kind of backup adds peace of mind when you’re relying on your gear to perform trip after 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"

Hi, everybody. Andy here with etrailer.com. Let's take a look together at this Triangle ST235/80R16 Load Range G Heavy Duty Radial Tire with the 16 inch black steel dual wheel. This special trailer tire, or ST tire, has sturdy sidewall so that it can handle heavy loads. It is created specifically for trailers, and it's not intended for use on other vehicles. As you know, radial ply tires are designed for trailers that are towed on the highway.
This radial tire is constructed with all steel belts to enhance the durability and extend the tread life. The computer generated tread design and premium rubber compound materials are gonna give you superior traction in wet or dry conditions. Now as I mentioned at the beginning of our time together and as we have stamped here on our tire, this is an ST235/80R16 tire. The section width is 9.25 inches. The outer diameter is 30 and seven eight inches.
This is a load range G, meaning it has a 14 ply rating. The maximum load as a single tire is 4,080 pounds at 110 PSI. The maximum load in a dual tire setup is gonna be 3,640 pounds at 110 PSI. This has a speed rating of L, indicating a maximum speed of 75 miles per hour. Now this heavy duty black steel wheel with one, two, three, four hand holes is designed to be used in dual wheel setups.
Now this wheel does have a high offset, so it allows for the wheel to be used as either an inner wheel in this orientation, or an outer wheel in this orientation on a dual wheel setup. The offset is either a positive or negative 5.35 inches. This steel wheel is sturdy and corrosion resistant. As you can see, it does feature a black powder coat finish, and it's over an eco primer so it's going to stand up really well to rust and corrosion. And 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 them separately on our website. And this does use wheel lug size of five eighths of an inch by 18 flange nut. The metal valve stem is included on this wheel. And the dimensions of this wheel, Looking at the diameter first, measuring bead seat to bead seat, is 16 inches. And the width, again, measuring bead seat to bead seat is six inches. So 16 inches on the diameter, six inches on the width. The wheel has a capacity of 3,860 pounds. And our bolt circle diameter, or bolt pattern, is eight on six and a half inches. And in case you don't know, the first number in the bolt pattern is the number of bolt holes, and 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 a bolt pattern with even numbers 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 real quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
