What Is The Difference In Wheel Offsets And Bolt Patterns, We Have It Broken Down For You:

Unsure which wheel offset to go with, or concerned with width gain? You’re not alone. Some of the most frequent questions we get when it comes to wheels, is about offsets – did you know that for most machines, wheel offset is a preference, not a requirement? This will help you better understand wheel offsets, and choose the best wheel for your ride.

Since 7” wide wheels dominate the market, our explanation focuses on that size wheel.

Some wheel manufacturers list offsets using the metric system and others list in our American equivalent.

METRIC SYSTEM – TRUE OFFSET

Offsets listed in millimeters refer to the distance between the mounting plate and the centerline of the wheel. This is what we consider “True Offset”. This measurement will be stamped in the back of your wheels as ET (another term used to describe wheel offset).

Common True Offsets: +40mm, +38mm, +30mm, +10mm, +5mm, +0mm, -47mm.

AMERICAN EQUIVALENT – INDUSTRY OFFSET

When wheel offset measurements are listed in our American equivalent, the first number indicates the “backspacing” (the distance from the back bead to the wheel mounting plate) and the second number indicates the distance from the mounting plate to the outer bead of the wheel (also known as the “Industry Offset”).

Common Industry Offsets: 6+1, 5+2, 4+3, and 2+5.

For example, a 5+2 offset means there is 5” from the back/inner bead to the mounting plate, 2” from the mounting plate to the outer bead. Pictured to the right is an illustration of this.

The chart below converts Metric measurements into the closest corresponding American measurement and will help you better understand what each offset will add to your stance over your factory wheels.

NOTE: Width gain is not given in exact measurement. Actual width gain can vary by machine and wheel manufacturer, but generally falls into these ranges:

Information About Bolt Patterns:

Most bolt patterns are stated in millimeters and there are 25.4 millimeters in one-inch. So If you measure with a tape measure in inches, you can convert to metric millimeters by multiplying (inches x 25.4), or you can easily find an online converter with a quick Google search.

HOW TO MEASURE BOLT SPACING

• For a 4-bolt wheel: remove your stock wheel and measure diagonally opposing stud bosses (center-to-center). Example spacings: 4/110mm; 4/115mm; 4/137mm; 4/156mm
• For a 5-bolt wheel: remove your stock wheel and measure diagonally opposing stud, bosses (from the back of one boss-to-the-center of the opposing boss). Example spacings: 5/114.3
• For a 3-bolt (ATV) wheel: remove your stock wheel. This one requires you to create a virtual circle (diameter) through the center of all three bosses. The bolt spacing is the distance across the middle of the diameter.
