Wheel Size Finder

Find generic-fit load wheels, steer wheels, and casters by size. Pick your wheel diameter to get started — measurements are in inches, bore in millimeters.

📏 How to measure your wheel
1. Diameter across the tread 2. Width hub face to hub face 3. Bore bearing inner diameter
  • Diameter — measure straight across the tread. A tape measure works; calipers are better.
  • Width — measure hub face to hub face, not just the tread (the tread is often narrower).
  • Bore — on wheels with bearings installed, it’s the bearing bore (your axle size). On bare wheels it’s the hub bore — the outside diameter of the bearing it accepts.
  • Worn wheel? Polyurethane wears down — a wheel measuring 3.1" is almost certainly a 3.25". When between sizes, pick the next size up.
