2004 Acura MDX Wheel Interchange
tl;dr
2004 Acura MDX uses 5x114.3 bolt pattern, 64.1 mm hub, M12x1.5 threads. The data on this page shows a 19x8 ET45 wheel and a 235/65R17 tire. That mismatch suggests multiple OEM setups or incomplete data. Confirm your exact OEM size, then use the calculator to model changes. Keep overall tire diameter close to stock, verify clearances, and torque correctly.
Recommendation
Start from your verified OEM wheel and tire size. If your door sticker or manual shows 235/65R17, treat 17 inch as your baseline. If your vehicle currently has 19 inch wheels, measure and enter those as your baseline. Use the on-page calculator to compare donor wheels or custom sizes, then confirm fit with a physical test fit before driving.
Known OEM fitment for 2004 Acura MDX
Values below reflect reported data for this model year. Some values may vary by trim or package. If anything conflicts with your vehicle, trust OEM sources and update the calculator accordingly.
| Parameter | Value | Notes |
|---|---|---|
| Bolt pattern | 5x114.3 | 5 studs on 114.3 mm PCD |
| Center bore | 64.1 mm | Use hub-centric rings if aftermarket bore is larger |
| Thread size | M12 x 1.5 | Confirm lug seat style for your wheels |
| Example wheel | 19 x 8.0, ET45 | Backspacing 5.77 in reported |
| Example tire | 235/65R17 | This tire fits a 17 inch rim |
There is a wheel-to-tire size mismatch in the examples above. This page’s calculator lets you set the true baseline that matches your vehicle.
Impact
Wheel and tire changes affect clearance, handling, and speedometer accuracy. Offset changes move the wheel in or out, which can affect scrub radius and bearing load. Wider wheels or tires can rub liners or suspension if inner clearance is reduced. Larger overall diameter can contact the body on compression or steering lock. Smaller overall diameter reduces ground clearance and can increase engine RPM at cruise.
Risks
- Incorrect hub bore leads to vibrations without proper hub-centric rings.
- Wrong lug seat type or length can cause loosening or stud damage.
- Overly low offset can poke past fenders and contact on bumps.
- Overly high offset can hit struts or control arms on turn.
- Tire diameter changes can alter ABS and AWD behavior if excessive.
- Brake caliper clearance issues can appear with some wheel spoke designs.
How to use the calculator on wheelinterchange.com
Step 1. Confirm your OEM baseline
- Check the driver door jamb tire label for size and pressures.
- Check the owner’s manual for wheel and tire specs.
- If uncertain, ask a dealer to confirm by VIN or look up your OEM wheel part number.
- Measure your current wheels if they differ from the label.
Step 2. Set up the comparison
- Installed on: choose 2004 Acura MDX.
- Wheels from: pick the donor vehicle or use Custom wheel size.
- Enter custom rim diameter, width, and offset. Set tire width and aspect ratio.
- Note that changing rim diameter updates tire diameter in the comparison. Keep an eye on overall tire diameter.
Step 3. Read the outputs
- Inner clearance: keep at least a safe margin to struts and arms. More is safer.
- Outer poke: avoid protrusion beyond the fender to prevent rubbing.
- Overall tire diameter: aim to stay close to your OEM diameter. A small change, typically around 3 percent or less, is a common target.
- Backspacing vs offset: both describe inboard position. Use whichever you have, but keep them consistent.
Step 4. Physical test fit
- Mount one front and one rear wheel with no tire contact points.
- Turn lock to lock and check liner and arm clearance.
- Cycle suspension with a jack to simulate compression and check for rubbing.
- Torque lugs to the OEM spec for your vehicle. Re-torque after 50 to 100 miles.
Checklist
- Studs x PCD: 5x114.3 confirmed.
- Hub bore: 64.1 mm confirmed.
- Thread: M12x1.5 confirmed.
- Baseline tire size verified from your door label or manual.
- Offset and width changes checked with the calculator.
- Hub-centric rings on hand if needed.
- Lug seat type matches the wheel seats.
- Proper torque, re-torque scheduled.
Gotchas
- Do not assume all 2004 MDX trims share one wheel size. Verify yours.
- Some aftermarket wheels have larger bores. Plan for 64.1 mm rings.
- Tire sidewall shape varies by brand. A “same size” tire can still rub.
- TPMS configuration may differ on replacement sensors. Plan accordingly if equipped.
Tools and parts
Next actions
- Verify your OEM wheel and tire size from the door label or manual.
- Set the calculator baseline to match your verified size.
- Enter candidate wheels and tires, then review inner clearance, poke, and diameter change.
- Order correct hardware: hub-centric rings, matching lug nuts, and a torque wrench.
- Test fit, check clearances at lock and compression, then torque to spec and re-torque later.
