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

JLU 4xe stock-height warning: 37s may fit physically, but owner evidence shows bump-compression rubbing. Recommend clearance correction before calling it clean.

Required checks

• tire-size calibration / programmer

• wheel backspacing or offset validation

• axle gearing review

• bump-compression and full-lock rubbing check

• flex and bump-stop clearance validation

Recommended checks

• brake performance review

Warnings

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

• For real trail use, 3.5 inches is the safer default starting point unless a specific exception applies.

• A stock-height 2024 JLU 4xe Rubicon may fit 37s physically, but has owner-reported rubbing on decent bumps.

• Do not mark stock-height 4xe/37s as clean fitment without a clearance solution.

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

Missing inputs

• actual tire diameter

• wheel backspacing

• wheel offset
