Video Transcript for What to Know About the Provider ST225/75R15 Radial Trailer Tire w/ 15" Black Mod Wheel

Hello everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this Provider ST225/75R15 radial trailer tire in a load range D, mounted on this 15 inch black modular steel wheel, with the six on five and a half inch bolt pattern. Now this tire wheel assembly is ideal for stock trailers, utility trailers, and even campers. The wheel uses a nice steel wheel, has the modular design. And when we say modular design, that's the one that has the round holes all the way around the wheel.

This wheel is very sturdy and rust resistant. The wheel itself goes through a three-step finishing process, which will include a zinc phosphate bath an e-coat primer, and then a black powder coat on the outside of the wheel. And if we spin it around to the back of the wheel, they actually lightly e-coated on the inside to reduce friction, provide rust resistance. Now this wheel does use the ITR technology. I want to show you what that is.

Basically, it stands for improved torque retention and it's designed to help keep the wheel securely in place on your trailer. Basically right here where the stud holes are, their stud holes are uncoated. And then they're beveled to give you better clamp force retention. The tire on this is a radial tire. It is constructed with double steel belts, double polyester cords for a long life.

It's great for highway use and they do use a nylon tread firming belt overlay to help prevent tread separation. And the tire itself is bake tested to ensure that the rubber will hold up over time. Now, also on this tire, if I spin it around here you can see they use a nice automotive grade tread design, and it has the sipes, the sipes are those cuts that are in the tread blocks. Those sipes will help channel water away from the tire and improve traction during wet, snowy or icy conditions. Now, this is a ST tire, which stands for special trailer tire, and it is designed to couple the strength of a bias tire with the durability and stability of a radial tire.

And it is created specifically for trailers. It's not intended for use on any other vehicles. This assembly does come with a two-year platinum plus warranty, which will include emergency tire change service and other benefits, and the assembly does meet the DOT, which is the department of transportation specifications. And it does exceed the federal motor vehicle safety standards. Few specs on this, starting with the wheel. The diameter of the wheel, just the wheel is 15 inches. The width on just the wheel by itself is six inches wide. The wheel does have a bolt pattern of six on five and a half inches. And if you want to measure that on a wheel, that's an even number of lugs. Like in this case, six. It's pretty easy to do because the lug holes are right across from each other. So you just pick any lug hole. And then you measure from the center of that lug hole to the center of the lug hole right across from it. So on this wheel, it'll measure five and a half inches. So it's a six on five and a half inch bolt pattern. This wheel does use the wheel lug size of a half inch by 20. The weight capacity on just the wheel by itself is 2,830 pounds. And the pilot hole diameter, which is this large hole here in the center of the wheel, goes over the hub on your trailer. Diameter of that opening is 4.25 inches. Now the tire size, which will be stamped on the sidewall is ST for special trailer 225/75R15. The R means that is a radial tire. Section width on this is 8.8 inches. Overall diameter from the bottom to the top when it's inflated is 28.3. And this tire is a load range D which means it's an 8 ply rated tire. So it does have a maximum load capacity of 2,540 pounds at 65 PSI. And the last thing I do want to mention is most all the new trailer tires are coming through with a speed rating stamped on them now, and they stamp it on the sidewall by using a letter designation. And where you'll find that is right after the size we just went over, you'll see two numbers for a load index, and at the very end of that, there'll be the letter M, speed rating M, will stand for 81 mile per hour speed rating. But that should do it for the review on this Provider ST225/75R15 radial trailer tire in a load range D mounted on this 15 inch black modular steel wheel with the six on five and a half inch bolt pattern..
