What bolt pattern and center bore does the 2021 Acura RLX use?
The 2021 Acura RLX uses a 5×120 bolt pattern with a 64.1 mm center bore. Selecting rims machined or hub-ring adapted for 5×120 eliminates steering vibration and ensures proper lug seating.
Do different 2021 Acura RLX trims share the same wheel size and offset?
Across 2021 Acura RLX trims (3.5i, 3.5i SH-AWD), compatible wheels measure 19"–20" in diameter and 8"–8.5" wide with offsets around ET50 (5×120 bolt pattern). Larger brake packages may require the upper end of the compatible diameter range.
Can forged, flow-formed, or cast alloy wheels clear 2021 Acura RLX brakes?
