What size tires fit a 2017 Acura RDX?
The standard tire size for most 2017 Acura RDX models is 235/60R18 on 18-inch wheels; some trims offer larger wheels with sizes such as 235/55R19 or 235/50R20. Always verify the exact size on the door jamb placard or in the owner's manual for your specific build.
Understanding which tires fit your 2017 RDX depends on the wheel size your vehicle was equipped with. Tire sizes are chosen to match the factory wheels, suspension, and ride quality, and they can vary by trim and optional packages. This article explains the common OEM sizes by wheel diameter and offers guidance for replacements and substitutions.
Factory tire sizes by wheel size
The following list maps typical OEM tire sizes to wheel diameters you might find on a 2017 RDX. Use it as a reference to identify the correct replacement when your car has the corresponding wheel size installed.
- 18-inch wheels: 235/60R18
- 19-inch wheels: 235/55R19
- 20-inch wheels: 235/50R20
These sizes reflect common OEM configurations across various trims and wheel packages for the 2017 RDX. If your vehicle has a different setup due to regional specs or aftermarket wheels, double-check the door placard or consult Acura support for the exact specification.
Important considerations when replacing tires
When selecting tires that differ from the factory size, aim to keep the overall diameter within roughly 2–3% of the original to preserve speedometer accuracy, ABS functioning, and ride characteristics. Always match or exceed the original load index and speed rating, and ensure the tire width and sidewall height will clear suspension components and fenders.
If you plan to change wheel sizes (for example, upgrading to larger diameter wheels), consult a tire professional to verify compatibility, potential rubbing issues, and any necessary adjustments to the vehicle’s electronic systems or alignment.
Summary
For a 2017 Acura RDX, the OEM tire sizes correspond to wheel size: 18" wheels use 235/60R18, 19" wheels use 235/55R19, and 20" wheels use 235/50R20. Always confirm the exact size from the door placard or owner’s manual for your specific vehicle, and consider diameter consistency and load ratings when substituting tires.
