Tyre Fitment Cheat Sheet (Backspacing, Offset, Rubbing)

Backspacing vs Offset: Less backspacing (or more negative offset) pushes wheels outward to clear arms/sway bar.

• JK/JL sweet spot for 35s: 4.5–4.75" backspacing on 17x8.5/9.
• 37s: 4.25–4.5" + bump stops + correct caster.
• Beadlocks: check ADR/road rules in your state.

Common rubbing: pinch seam (JL), inner liners, sway bar at full lock, rear flare at full flex.
