Common questions
What bolt pattern does the Acura RDX have?
The RDX has kept the same 5×114.3 pattern, 64.1 mm hub and M12×1.5 cone-seat bolts across all three generations — only the offset changed: ET45 through 2007–2018 (TB1–TB4), ET50 from the 2019 redesign (TC1/TC2) on, including the 2022 facelift. Check the table above for your exact generation, and confirm against a wheel or the owner's handbook before buying.
Will other wheels fit my RDX?
Only wheels with exactly the same bolt pattern — bolt pattern has no working tolerance. The centre bore must also be equal to or larger than the hub (a larger bore just needs spigot rings). A different pattern needs bolt-on adapters, which also push the wheel outward and change the track.
What is the centre bore on a RDX?
64.1 mm on the current car. The bore is the hole in the middle of the wheel; it has to clear the hub spigot or sit on a spigot ring.
Bolt pattern is only part of fitment. The offset (ET) decides where the wheel sits in the arch — work that out with the wheel offset calculator. For tyre sizing on a new wheel width, use the tire size calculator.
