Finding Dual Wheel ID Numbers, Terms & Measurements:
What we need to know for correct fitting Dual Wheels:
Make, Model and Year of the chassis, Tire/Wheel Size,
Number of Lug Nuts and Hand holes
and the Accuride Wheel Number found on the steel wheel itself.
Hub Piloted Wheels vs Stud Piloted Wheels:
The Diagrams below show the two types of Lug Nuts.
Cone, Tapered, "Ball-Seat" Nut, Found on Stud Pilot wheels.
Fit into chamfered holes in the wheels, center the wheel on the hub. Use Imperial Thread.
On Heavy Duty wheels, Left threads on the left and right threads on the right side.
Flat Bottom Flange Nuts, Found on Hub Pilot wheels.Hub Pilot wheels have a hole middle that centers the wheel on the hub, use metric thread studs.
The Hub Piloted configuration is stronger, and DOT required the transition from stud-piloted to Hub-piloted wheels during the 1990's.
Benefits of hub-pilot configuration:
Reduction of wear between the nut and chamfered hole
Greater clamping force for a given torque
Eliminated necessity for left hand threads on the left side
