37s Advisor Preview

Draft graph logic for JL/JT 37-inch tire builds. This page is intentionally labeled as a preview: it shows recommendation branches, required checks, warnings, and evidence IDs before anything becomes checkout-ready.

Draft advisor logic — not checkout fitment

This preview is based on the local 37s brain cell and includes owner-submitted 392/4xe exceptions. It still needs forum/community corroboration and shop review before production recommendations.

Advisor answer

37s detected: treat this as a system upgrade and validate the missing vehicle/tire/wheel details before recommending parts.

Required checks

• tire-size calibration / programmer

• wheel backspacing or offset validation

• axle gearing review

• flex and bump-stop clearance validation

• non-Rubicon 37s/no-lift clearance validation

Recommended checks

• brake performance review

Warnings

• 37s are a system upgrade: clearance, calibration, gearing, steering, braking, and driveline stress all matter.

• 2–2.5 inch 37s builds can drive fine on road but need flex/rubbing validation before trail recommendation.

• Non-Rubicon JL/JLU with 37s and no lift is outside the validated evidence path; require lift/clearance validation before recommending.

Missing inputs

• actual tire diameter

• wheel backspacing

• wheel offset
