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.

Radial Tires vs. Bias Tires

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.

• If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
• If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
• If D = 3", then the bolt pattern is 5 on 5"
• If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"
