tl;dr

Use the calculator to compare any donor wheel to your 2016 ILX. Start from the factory baseline above. Keep overall tire diameter close to stock. Watch inner clearance, fender poke, and lug engagement. Match the 64.1 mm hub with rings if needed. Confirm seat style and torque using Acura sources.

Recommendation

Build around the OEM baseline: 17x7 ET50 with 215/45R17. If upsizing, adjust width and offset so inner clearance remains safe and outer poke stays under the fender. The on-page calculator shows inner and outer changes as you edit width and ET. Keep overall tire diameter change small to preserve gearing and ABS behavior. Use hub-centric rings if your new wheel’s center bore is larger than 64.1 mm. Use M12x1.5 hardware that matches the wheel’s seat style. Reuse or service TPMS during tire work.

Impact

  • Width and offset change track width and poke. More positive ET pulls inward; less pushes outward.
  • Inner clearance affects struts, liners, and brake hoses. The calculator quantifies that change.
  • Tire diameter shifts speedometer and gearing. The calculator updates this as you change sizes.
  • Heavier assemblies increase unsprung mass. Expect firmer ride and slower damping.
  • Wider tires can improve grip but may tramline and hydroplane sooner.

Risks

  • Rubbing on fenders or liners from excess outer poke.
  • Interference at the strut or knuckle from reduced inner clearance.
  • Insufficient lug nut engagement or wrong seat style causing loosening.
  • Vibration from non hub-centric fitment if rings are omitted.
  • Speedometer error from large diameter changes.
  • TPMS faults if sensors are damaged or not serviced.

Checklist

  • Confirm your current tire placard size on the door jamb.
  • Open the calculator. Set “Installed on” to 2016 Acura ILX.
  • Compare “Wheels from” a donor or enter a custom size.
  • Adjust rim width and offset until inner clearance stays safe. Avoid reducing inner clearance to near zero; leave visible margin.
  • Keep overall tire diameter close to stock. Many techs aim within a few percent.
  • Check brake caliper clearance. The calculator shows spoke-to-hub geometry changes; still confirm physically when test-fitting.
  • If the new wheel bore is larger than 64.1 mm, plan hub rings.
  • Use M12x1.5 hardware with the correct seat for your wheel.
  • Service or transfer TPMS, then relearn per Acura procedure.
  • Torque lugs in a star pattern to the OEM spec. Re-torque after 50–100 miles.

Gotchas

  • Spare tire well and jack points still need to work with the new setup.
  • Chain clearance in winter can be tighter with wider tires.
  • Some aftermarket wheels need shorter or longer hub rings; measure before ordering.

Helpful tools

If any spec varies by trim or package, confirm against your VIN or Acura service data. If a value is unclear, use the on-page calculator outputs and cross-check with OEM documentation before purchasing.
