OEM wheel and tire fitment specs for the 2006 Acura MDX, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
2006 Acura MDX Fitment Specs
Baseline mounting dimensions used for interchange decisions.
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.
2006 Acura MDX Bolt Pattern, Wheel Specs, and Fitment Guide
This page focuses on safe, accurate fitment for the 2006 Acura MDX. Where values are unknown or may vary by trim or market, we show what is known and explain how to confirm the rest using the on-page calculator and OEM sources. Do not assume compatibility without verifying bolt pattern, center bore, offset, brake clearance, and tire diameter.

Notes:
The presence of both a 19x8 ET45 wheel datapoint and a 235/65R17 tire datapoint indicates factory equipment may vary by trim/package or market. Do not assume your vehicle has these exact sizes.
Backspacing measurements can vary depending on how the wheel width is referenced. If you are checking backspacing at home, measure carefully from the mounting pad to the wheel’s inboard rim lip.
How to confirm your exact stock size
If your MDX’s original equipment differs by trim, confirm your specific vehicle’s specs before comparing donor wheels:
Check the tire-information placard on the driver’s door jamb for factory tire size and load/speed ratings.
Compare with your owner’s manual or an Acura dealer parts department (VIN lookup).
Measure an existing wheel if needed: bolt pattern, center bore, width, and offset stamping (often cast inside the wheel, example “19x8J ET45”).
Using the wheelinterchange.com calculator
The on-page calculator lets you compare a donor setup against your 2006 Acura MDX and also test custom wheel and tire sizes:
Set “Installed on (your vehicle)” to 2006 Acura MDX.
Pick a “Wheels from (donor vehicle)” or enter a “Custom wheel size” (rim diameter, width, offset).
Adjust “Custom tire size” (section width and aspect ratio). When you change rim diameter, the tool updates the compared tire diameter so you can track speedometer impact and fender clearance.
Review inboard clearance to suspension/brakes and outboard “poke” to fender. Keep changes modest to reduce rubbing risk.
Only proceed if the calculator shows acceptable clearances and tire diameter close to stock. Large diameter changes can affect speedometer accuracy, ABS/traction behavior, and ride/handling.
Safety-first compatibility checklist
Bolt pattern must match exactly: 5x114.3.
Center bore: 64.1 mm hub size on the vehicle. A wheel with a larger bore can be used with 64.1 mm ID hub-centric rings; a smaller bore will not fit.
Offset and backspacing: Verify with the calculator. Too much positive offset risks inner rub; too little risks outer fender interference.
Brake clearance: Spoke and barrel shape matter as much as diameter. Test-fit and rotate the wheel by hand to ensure caliper and knuckle clearance.
Lug hardware: Keep M12x1.5 thread pitch and match the lug seat style to the wheel design. Ensure full thread engagement; do not use damaged or mismatched lugs.
Tires: Match tire width and aspect ratio to the wheel width and the calculator’s clearance results. Maintain proper load index and similar overall diameter to stock.
Torque: Use an accurate torque wrench and follow Acura’s published torque spec from the owner’s manual or service manual. Re-check torque after a short drive cycle.
TPMS: If equipped, transfer or program sensors compatible with the MDX.
