Hub-Piloted Wheel
This wheel is hub piloted, which means that it centers on the hub, not the lugs. The wheel requires the use of flange nuts (sold separately) for installation.
Corrosion-Resistant Finish
The steel wheel goes through a 3-step finishing process that makes it both attractive and corrosion resistant. The wheel is first submerged in a zinc phosphate bath to ensure good paint adhesion. It is then e-coated with an acrylic primer base and finished on both sides with baked-on DuPont powder paint.
Provider radials are constructed with double polyester cords and double steel belts for increased durability and endurance. A protective layer of nylon is wrapped around the steel belts to help prevent tread separation. Provider radials are bake tested - a process usually reserved for automotive tires - to ensure that the rubber holds up over time.
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.

Hello, everybody. This is Jeff at etrailer.com. Today I'm gonna take a look at this Taskmaster Provider 215/75R17.5 radial tire in a load range H on this 17.5 inch white modular wheel with an offset, and an eight on 6 1/2 inch bolt pattern. Now, this tire wheel assembly's ideal for heavy duty trucks and trailers. The wheel is a heavy-duty steel wheel. It is the modular design.
When we say modular design, that's the one that has the round holes all the way around the wheel. It is sturdy and corrosion-resistant. The wheel does go through a three-step finishing process, which will include, first, the zinc phosphate bath, then an e-coat primer, and then a nice white powder coat on both sides of the wheel. Now, this wheel is a hub piloted wheel, which means it'll center on this hub so that it will require a close fit of the center pilot hole on the wheel to the hub. The pilot hole diameter is 4.76 inches.
And hub pilot wheels do require the use of flange nuts for installation. Now, those we do sell separately on our website. They do use a flange nuts size of 5/8 inch by 18, and they're usually listed on this product page as a related product. Now, this wheel does have a positive offset of 0.08 inches. And a positives offset is when the hub mounting surface, so this is your mounting surface, will go up against your hub.
So basically, when it is in front, here's the wheel center line. Right down the middle is the center line of the wheel. So when it's a positive offset, that means it's in front of that wheel center line, so a positive offset will move the tire towards the center line of the trailer. Now, the tire on this is a radial tire. It is constructed with double steel belts, double polyester cords for a nice long life.
It's great for highway use. 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 holds up over time. It is created specifically for heavy duty trucks and trailers, not intended for use on other vehicles. And this assembly does meet the DOT which is Department of Transportation, specifications, and it will exceed Federal Motor Vehicle Safety Standards. Zoom in again. We'll talk about the wheel. The measurement on the wheel, the diameter on the wheel is 17 1/2 inches. The width on just the wheel itself is 6 3/4 inches. The bolt pattern on this wheel is an eight on 6 1/2 inch bolt pattern. And if you want to measure that on a wheel, that's an even number of lugs, in this case, eight holes. You just pick any hole, because the holes are directly across from each other, so when you go to measure it, pick any hole, measure from the center of that hole directly across to the center of the hole right across from it. So on this wheel, it'll measure 6 1/2 inches, so it's an eight on 6 1/2 inch bolt pattern. The weight capacity on just the wheel is 6,005 pounds. Now the tire size, which is stamped on the sidewall, right here, you can see 215/75R17.5 The R stands for a radial tire. Now the section width, which is gonna be the overall width of the tire, is 8.3 inches. Overall diameter from the bottom to the top when it's inflated is 30.2 inches. This tire is a load range H, which means it's a 16 ply tire. Maximum load on it is 4,805 pounds at 123 psi. And the last thing I do wanna mention is most all your new tires are gonna have a speed rating on 'em. And they stamp it on the side wall with a letter designation. And where you find that is right after the tire size we went over, you'll see two numbers for the load index, and then they stamp a letter M. Speed rating M will mean this tire has an 81 mile per hour speed rating. But that should do it for the review on this Taskmaster Provider 215/75R17.5 radial tire in a load range on this 17 1/2 inch white modular wheel with the offset, and an eight on 6 1/2 inch bolt pattern..
