Recommendations
-
Want original, off-road capable setup? OEM #95416 or #5905 18″ wheels with tires—excellent when paired with Falken or BFG choices.
-
Budget-conscious? Look for used OEM take-off sets (often sub-$1,000 if local/used).
-
Preference for lighter or 20″ styling? Choose 18×8.5 or carefully vetted 20×9 Trail Boss-style aftermarket rims that maintain bolt pattern compatibility and safe offset.
