We’ve provided the following overview to help explain how skid steer wheel offsets are measured and how they affect machine performance and application.

In the diagram below, the skid steer wheel is shown with a green centerline, commonly referred to as zero offset. This line represents the reference position of the bolt plate.

• When the bolt plate is positioned inward toward the machine from the centerline, this is considered an outset measurement.
• When the bolt plate is positioned outward away from the machine from the centerline, this is considered an inset measurement.

Offset Examples

• A Case 1835C skid steer has a 0.38-I offset. This means the bolt plate is positioned 0.38 inches inset from the centerline (zero offset), resulting in the correct wheel offset for that machine.
• A Kubota SSV65 skid steer has a 0.25-O offset, meaning the bolt plate is positioned 0.25 inches outset from the centerline.

When reviewing our wheel specifications, the final letter will always indicate the offset type:

• I = Inset
• O = Outset

Wheel Reversal and Machine Stance

Some skid steer models allow the wheels to be reversed to adjust the machine’s stance without affecting operation.

• A wider stance improves stability on uneven terrain and slopes, and may allow the use of over-the-tire tracks without wheel spacers.
• A narrower stance is beneficial in confined environments such as dairy barns or tight work areas. In some cases, operators reverse the wheels to keep the machine width within the footprint of the bucket or attachment.

Measuring Offset When It’s Unknown

If the wheel offset is unknown, it can be determined by measuring from the outer lip of the wheel (valve stem side) straight down to the bolt plate. This method is especially useful when replacing a single wheel and matching it to the remaining three on the machine.
