Technical Trailer Wheel FAQ's

Q: HOW DO I DETERMINE MY BOLT PATTERN?

A:  Match wheels to the hub by number of bolts and bolt circle.

To determine the bolt circle on wheels with an even number of bolt holes,

measure center-to-center on bolt holes directly across from each other on the diameter (example: 8 on 6.5 would mean 8 bolt holes with 6.5 center-to-center diameter).

On odd number bolt wheels, measure any bolt hole center to the point halfway between bolt holes on the diameter ( Example: 5 on 4.5 would mean 5 bolt holes with 4.5 measure to a point halfway between the opposite bolts).

 

Q:  HOW DO I DETERMINE THE WHEEL OFFSET?

A:  Offset is the distance between the mounting face of the disc and rim centerline.

INSET: Refers to the distance when the mounting face is outboard of the rim centerline.

OUTSET: Refers to the distance when the mounting face is inboard of the rim centerline.
