How to Measure Tractor Rim Bolt Patterns

Accurate bolt-pattern measurement prevents fitment mistakes when ordering tractor rims, dual wheel power board setups, and custom ag wheels.

Measurement Checklist

• Count total bolt holes on the hub and rim.
• Measure center-to-center distance across opposite holes.
• Record center bore, pilot type, and offset/backspacing.
• Confirm tire size, machine model, and intended field use.

For odd bolt circles or adjustable tractor wheel systems, send photos and measurements before ordering. CFI can help verify fitment for tractors, grain carts, wagons, and implement wheels.
