2009 Acura TL Wheel Fitment Guide
tl;dr
The 2009 Acura TL data on this page shows a 5x120 bolt pattern, 64.1 mm center bore, and M14x1.5 threads. Known OEM wheel is 18x8 ET55 with 6.17 in backspacing. Tire sizing in the data also shows 245/50R17, which suggests multiple OEM packages. Trim and package matter. Verify your exact setup on the door jamb label and with the on-page calculator before buying wheels or tires.
Recommendation
Confirm your exact trim and OE sizes from the driver door placard and owner manual.
Use the wheelinterchange.com calculator to load your 2009 TL as Installed on, then compare candidate wheels under Wheels from or Custom wheel size.
Match the 5x120 bolt pattern and 64.1 mm hub bore. If the donor wheel bore is larger, plan hub-centric rings. If smaller, it will not fit.
Keep offset changes modest to protect inner clearance and fender poke. Review the calculator’s inner and outer clearance results.
Keep overall tire diameter close to your OEM reference. The calculator updates tire diameter as you change rim diameter.
Check brake caliper and knuckle clearance with a physical test fit whenever possible.
Use correct-seat lug nuts for the wheel, M14x1.5 thread, and torque to OEM spec from your service manual.
Impact
Diameter and aspect ratio changes affect speedometer, ABS thresholds, and gearing feel. The calculator highlights diameter delta.
Offset and width shifts change inner clearance and outer poke. That influences fender rub and bearing load. Review the comparison deltas.
Center bore and hub-centric fit reduce vibration. Rings help when the wheel bore is larger than 64.1 mm.
Heavier wheels and tires can slow steering response and increase braking distance.
Risks and gotchas
Spec variance by trim. The mixed 18 in wheel and 17 in tire data indicates multiple OEM packages. Do not assume one size fits all.
Bolt pattern confusion. 5x120 is listed here. Do not attempt to mount 5x114.3 or other patterns.
Center bore mismatch. A wheel with a smaller bore than 64.1 mm will not seat. Larger bores require rings to stay hub-centric.
Lug seat type. Cone vs ball seat must match the wheel. Wrong seats loosen and damage studs.
Brake and knuckle interference. Lower offsets push outward but can still contact calipers on spoke backs. Test fit.
AWD considerations. If your TL is AWD-equipped, avoid front-rear tire diameter mismatches.
TPMS compatibility. Relearn or replace sensors as needed for new wheels.
Post-install maintenance. Re-torque after the first short drive cycle to catch settling.

How to use the calculator effectively
Set Installed on to 2009 Acura TL to establish your baseline.
Enter a donor vehicle or use Custom wheel size to try new diameter, width, and offset.
Adjust Custom tire size to keep overall diameter close to your baseline. The tool updates diameter as rim diameter changes.
Review inner clearance, outer poke, and diameter change. Aim for modest deltas and confirm physically when possible.
Next actions
Checklist:
Confirm door-jamb sizes and trim details.
Baseline your OEM wheel and tire in the calculator.
Compare candidate wheel specs and tire options until deltas look acceptable.
Plan hub-centric rings if wheel bore is bigger than 64.1 mm.
Buy correct-seat M14x1.5 lug nuts and a quality torque wrench.
Test fit, spin-check for caliper clearance, then install and torque to spec.
Re-torque after 50-100 miles and monitor for rubbing under load.
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.
