Q: HOW TO FIGURE OUT MY BOLT PATTERN?A: Match rim 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 MEASURE MY 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.
