tl;dr
The 2007 Acura RDX runs 5x114.3, 64.1 mm hub bore, M12x1.5 studs. OEM wheels are 18x7.5 ET45 with 5.52 in backspacing, on 235/55R18 tires. Use the on-page calculator to compare donor wheels and custom sizes. Keep the hub bore at 64.1 mm or use rings if larger. Verify inner clearance and fender poke before buying.

Use the calculator to model fitment
Select your RDX as “Installed on (your vehicle)”.
Pick any candidate under “Wheels from (donor vehicle)”. Match 5x114.3.
Center bore must be 64.1 mm or larger. If larger, plan rings.
Adjust “Custom wheel size” to match the donor wheel’s width and offset.
Adjust “Custom tire size” to see overall diameter change.
Target a hub-centric, near-stock fit
Keep overall tire diameter close to stock for speedometer accuracy.
Aim for inner clearance that avoids strut and liner contact at full lock.
Avoid excessive poke past the fender edge.
Confirm brake caliper clearance if downsizing diameter.
Impact
Wider wheels increase outside poke and can rub on compression.
Lower offset pushes the wheel out, relieving inner clearance but risking fender rub.
Higher offset pulls the wheel in, improving fender coverage but reducing strut clearance.
Smaller diameters may interfere with calipers; larger diameters change ride feel.
Taller tires soften impacts but can rub; shorter tires sharpen steering but reduce sidewall protection.
Risks
Center bore smaller than 64.1 mm will not seat. Do not force it.
Larger bore without rings can cause vibration. Use hub-centric rings.
Mismatched lug seat type (conical vs ball) can loosen. Match the wheel’s seat profile.
Spacers change stud engagement and load. Use only hub-centric, with proper hardware.
Brake and knuckle clearance may be tight on inner barrel and spokes.
Speedometer and ABS behavior can shift with large diameter changes.
TPMS requirements vary by sensor and wheel design. Confirm compatibility with OEM sources.

Checklist
Confirm your baseline: 5x114.3, 64.1 mm bore, M12x1.5, 18x7.5 ET45.
Open the calculator and load your RDX under “Installed on”.
Enter donor wheel width and offset. Check inner and outer movement.
Test tire sizes in the tool. Keep overall diameter close to stock.
Measure brake clearance if changing diameter or spoke design.
Plan hub-centric rings if donor bore exceeds 64.1 mm.
Match lug seat type and thread. Use quality nuts and proper torque per manual.
Test-fit one wheel. Turn lock-to-lock. Compress suspension safely. Check all clearances.
After install, road test and recheck torque once the wheels are cool.
If any value for your trim differs, verify against your door placard, owner’s manual, and the on-page calculator readouts. When in doubt, stick close to the OEM spec and validate with a careful test fit.
Methodology and sources
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
Bolt pattern / PCD
Center bore direction (donor wheel bore must not be smaller than the hub)
Wheel diameter, width, and offset against known OEM ranges
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
