2013 Acura ILX Wheel Fitment Guide
tl;dr
Use 5x114.3 wheels that center on a 64.1 mm hub. Thread size is M12 x 1.5. The stock setup is 16 x 6.5 with ET 45 and 205/55R16 tires. Stay close to OEM offset and overall tire diameter. Use the calculator on this page to compare donor wheels and custom sizes before you buy or mount anything.
Recommendation
I set up 2013 ILX fitments with these steps to keep safety margins intact:
Match the bolt pattern: 5x114.3 only.
Hub-centric fit: wheel center bore 64.1 mm, or larger with hub-centric rings to 64.1.
Fasteners: M12 x 1.5 lug nuts that match your wheel seat type. Confirm seat style with the wheel maker.
Start from stock geometry: 16 x 6.5, ET 45, 205/55R16.
Use the calculator:
Set Installed on: 2013 Acura ILX.
Compare a donor vehicle or enter a custom wheel width, diameter, and offset.
Adjust tire size. Keep overall tire diameter close to stock for speedometer accuracy.
Stay near the OEM offset to protect inner clearance and fender poke.
If the wheel bore is larger than 64.1, plan on hub-centric rings for smooth highway operation.
If trim or brake package is unknown, visually confirm caliper clearance during test fit.
Impact
Small changes affect multiple systems. Here is how I evaluate them:
Offset change: more positive ET pulls the wheel inward. Watch strut, spring perch, and inner liner. Less positive ET pushes outward. Watch fender lip and bumper liner on compression.
Width change: adds half the width increase to each side before offset effects. Combine with ET change in the calculator to see inner clearance and poke.
Diameter change: the calculator updates tire diameter. Larger tires can rub liners at full lock or over bumps. Smaller tires drop ride height and alter speedometer.
Centering: non hub-centric fits can cause vibration. Rings to 64.1 mm usually solve it if the wheel bore is larger.
Fasteners: wrong seat type or thread pitch can loosen or damage studs.
Risks
Trim variance: some trims may use different brakes or OE wheel sizes. Confirm by VIN, build sheet, or the calculator notes. Do a physical test fit.
Brake and barrel clearance: spoke and barrel shape matter. Do not assume a diameter clears. Spin the wheel by hand with the car safely lifted.
Incorrect lug nut seat: conical vs ball vs mag seat. Match the wheel seat exactly.
Center bore too small: 64.0 will not seat on a 64.1 hub. Never force-fit. Larger bore is fine with rings.
Unsuitable tires: load index and speed rating must meet or exceed OEM. Mixing old and new circumferences can upset ABS and stability control.
TPMS: sensor compatibility and relearn steps vary. Plan for programming if your new wheels need different sensors.
Next actions
Confirm your baseline:
Use the table below and your owner’s manual. If your trim differs, record what is on your car today.
Model your change:
In the calculator, set Installed on: 2013 Acura ILX.
Compare a donor vehicle or enter custom wheel and tire sizes.
Aim to keep overall tire diameter close to stock and offset near ET 45 unless a known clearance need dictates otherwise.
Check clearances:
Inner: strut body, spring perch, brake hoses, and liners.
Outer: fender lips and bumper liners at full lock and full compression.
Test fit safely:
Mount one front and one rear. Hand spin and turn lock to lock. Lower and bounce the suspension. Road test gently. Recheck for rub marks.
Torque the lug nuts to the Acura spec from your manual. Re-torque after initial miles.
If your trim varies, use the on-page calculator and OEM sources to confirm. Do not assume other sizes without checking clearances.

Gotchas
Do not force a smaller center bore onto the hub. It will not seat.
Do not mix seat styles on lug nuts. All fasteners must match the wheel seat.
Do not rely on diameter alone for brake clearance. Spoke shape matters.
Do not skip re-torque. Thermal cycling can relax clamping force.
Notes on variability
Some 2013 ILX trims may have different factory wheel and tire packages or brake hardware. If any value above differs on your car, trust the physical measurement and OEM documents. Use the calculator to model changes and confirm clearance with a test fit before mounting tires.
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.
