The size on the placard inside the driver's door jamb is the one your car left the factory with. Match that, not this table, if they differ; a previous owner may have changed wheels.

Worth knowing about the 2014 RDX
- Wipers. No blade maker source confirmed the front arm type, and Rain-X lists a Rock Lock 3 arm for the rear blade.
- Bulbs. Low beams take a D2S xenon capsule on some models and an H11 halogen bulb on others.
- Tire chains. The manual permits chains or cables, on the drive wheels only, fitted to the standard tire size. Chains for this size on Amazon →
- Tires. Chains go on the front tires only, and because clearance is limited the manual recommends SCC Radial Chain TC2212MM cables, and the spare is a T165/90R17 compact.
- Torque. Tighten lug nuts to 80 ft-lbs in a star pattern with a torque wrench, and re-check after the first 50 miles. This figure is from the owner's manual; an impact gun will overshoot it.
- Octane. The manual requires 87 octane and recommends 91 for full performance. Regular will not harm the engine; premium is a choice, not a requirement.
- Fuel. The manual recommends 91 octane premium and warns that fuel below 87 octane can damage the engine.
