The 20x9 +18 offset sits in a moderate, mainstream fitment zone for full-size SUVs—neither aggressive nor conservative—and will track close to stock stance on a raised suspension. Square tire sizing (matching width to wheel width) is a practical choice that avoids sidewall bulge and keeps speedometer accuracy intact. Verify your specific trim's suspension geometry and fender clearance during installation, as raised setups and factory trim variations can shift clearance margins.
