When you’re hauling serious weight or traveling long distances, this tire-and-wheel combo brings real peace of mind. The Triangle ST235/80R16 heavy-duty radial tire has a 14-ply rating and a 4,080-lb maximum load at 110 psi, backed by Load Range G strength and a 75-mph (speed rating L) limit that meets DOT specifications. All-steel belts and a computer-generated tread design help it stay stable under pressure and deliver solid traction on wet or dry pavement.
Radial ply design means the cords run at a 90-degree angle to travel direction, so the tire flexes smoothly without the cords rubbing together. That lower rolling resistance keeps heat buildup down on long highway runs and helps extend tread life. It’s made for consistent handling at higher speeds, so every trip feels steady and predictable mile after mile.
The wheel’s steel lug nut inserts keep the assembly locked in place and prevent wear around bolt holes. You don’t have to worry about constant retightening—the inserts maintain a secure hold on the hub to keep things tight when towing heavy or over rough surfaces. It’s a small detail that pays off in durability and safety.
The 16"?× 6" aluminum wheel is both lightweight and rustproof, with an open-spoke design that looks sharp while standing up to the elements. A clear coat finish on both sides protects against scuffs, scratches, and corrosion from road grime or moisture. With its black finish and 8 on 6-1/2" bolt pattern, it’s built to perform and keep its good looks through years of use.
Every Triangle tire in this setup comes with a 1-year worry-free guarantee—if it’s damaged within the first 12 months, it gets replaced at no charge. The wheel also carries a 2-year limited warranty, giving you straightforward protection along with heavy-duty performance right out of the box.
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"

Hello, neighbors and friends, Steve here with etrailer.com. Folks, today, we're looking at this nice Triangle ST235/80R16 Heavy-Duty Radial Tire with a nice 16 by six inch black aluminum wheel with and eight on 6 1/2 inch lug pattern and a Load Range G. So folks, this tire and wheel assembly is ideal for stock trailers, utility trailers, campers, those kind of things. It does sport a nice AM03 black aluminum wheel. It's super durable, lightweight, and rustproof. Has a beautiful open spoke design.
The design's pretty unique compared to most of the wheels you see out there. It's got a nice aesthetically looking finish to it I think. And it does have a nice clear coat finish over the powder coat finish that they have already. And that's on the front and the back, which you don't always see on the backside of wheels. A lot of times, they only cover the outside.
So that's a nice feature that they went ahead and did the whole thing. Now, something else to speak about is the lug inserts on the wheel itself. So those steel inserts inside where the lug net goes is, one, gonna help keep the wheel securely in place on the trailer hub, but it's also gonna prevent those holes from wearing down. Now, one thing to notice, you can use either a 1/2 inch by 20 thread count lug nut, or you can use a 9/16 by 18 count thread lug nut or wheel bolt. The pilot diameter here in the center is a 4.9 inch diameter.
There is no offset on this wheel. Now, the Triangle tire here is a heavy-duty special trailer radial tire, so it is designed only for trailers and is not intended for use on other vehicles. It's made of all-steel belts inside. That's gonna enhance the durability and extend the tread life. And the tread here is a computer-generated tread design to give premium traction in wet and dry conditions.
And it's also made with a nice rubber compound material that's superior to some other brands out there. The whole assembly here meets all DOT specifications. Once again, the wheel is a 16 inch diameter by six inch wide. That bolt pattern again is an eight lug on 6 1/2. And the way you determine on an even wheel like we have here today is, you take one lug and you measure center to center straight across, and you'll get that 6 1/2 inches. Now, once again, this tire capacity is a Load Range G, it's a 14-ply tire, and its max speed is 75 miles per hour with a speed rating of L. Now, if you we inchesre gonna measure the overall diameter on the outside to outside, I was getting 30 7/8 inches outer diameter. So in case you're worried about this fitting on your trailer and those spaces and specs you need to that measurement. The wheel capacity's rate at 4,400 pounds while the max load rating on the tire itself is 4,080 pounds at 110 psi. So folks, this is just a nice tire and wheel combo by Triangle. We've had these for a while, they work great on trailers, a great option for you. We've got multiple designs on the wheels and different finishes. There's some silvers and blacks like you see here today. And kinda as you see here today, there's a combo of that aluminum kinda silver color with the black. Well, folks, that's gonna wrap it up for our quick look today at this Triangle ST235/80R16 Heavy-Duty Special Trailer Tire. I'm Steven, thanks for watching.
Ratings & Reviews
Surprisingly the rims with tires arrived unscathed since there was nothing to protect them and the fact that they are very heavy. I do like the metal valve stems primarily for tire pressure sensors but not in etrailer description or video clip. Little disappointed with the age of tires (already 1 yr old) but don’t think that is controllable. Very pleased how fast they were delivered and they look very modern on my fifth wheel. I really like them.
