2012 Acura TL Wheel Fitment and Interchange Guide

Professional, safety-first guidance for selecting wheels and tires that fit. Use the calculator on this page to confirm every change before purchase.

tl;dr

• Known OEM data for this page shows: 5x120, 64.1 mm hub, M14x1.5 studs.
• Wheel listed: 18x8 ET55, 6.17 in backspacing. Tire listed: 245/50R17.
• The tire and rim diameters conflict. Trims may vary. Verify with the door placard or OEM sources, then use the calculator.
• Keep inner clearance safe and fender poke reasonable. Check brake and strut clearance.
• Match center bore and lug seat. Torque to OEM spec from the service manual.

Recommendation

Start by confirming your exact factory spec. The values shown here may be trim dependent, and the listed 18 inch wheel with a 17 inch tire indicates a mismatch.

• Check the driver door placard for the stock tire size.
• Confirm factory wheel size and offset through an OEM parts catalog or dealer.
• Set those confirmed values as the baseline in the calculator.

Use the calculator effectively

• In Wheels from (donor vehicle), enter the wheel you want to test, or edit Custom wheel size and Custom tire size.
• In Installed on (your vehicle), enter your verified factory specs.
• Adjust rim diameter, width, and offset. Watch inner clearance and outer poke.
• Changing rim diameter updates tire diameter. Keep overall tire diameter close to stock.

If you choose aftermarket wheels with a larger center bore, plan to install hub-centric rings to match 64.1 mm. Always match lug nut thread and seat style to the wheel design.

Impact

• Width change: Wider wheels push the tire sidewalls outward. Inner clearance may shrink near struts, knuckles, and liners.
• Offset change: Lower ET moves the wheel outward. Higher ET pulls it inward. Both affect scrub radius and loading.
• Diameter change: Changes overall tire diameter and speedometer error. The calculator shows percentage change.
• Backspacing: Drives inner clearance. Compare against suspension and brake hardware.
• Ride and handling: Larger diameter assemblies can add weight and reduce ride compliance. Shorter sidewalls sharpen response but can ride harsher.
• Bearing and stud load: Extreme poke or heavy setups increase stress. Stay conservative for daily use.

Risks and gotchas

• Spec mismatch: The data here lists an 18 inch wheel and a 17 inch tire. Do not mix without confirming trim and actual equipment.
• Center bore: Vehicle hub is 64.1 mm. If your new wheel bore is larger, use quality hub-centric rings sized to 64.1 mm.
• Lug hardware: Threads are listed as M14x1.5. Confirm your studs. Match lug seat to the wheel. Do not reuse damaged hardware.
• Stud engagement: Achieve full thread engagement. Avoid short shank lug nuts on thick wheel pads.
• Brake clearance: Spoke shape matters. Use the calculator for approximate clearance, then test-fit and rotate to check caliper bridges.
• Fender rub: Load the suspension and turn lock-to-lock. Check liners, fender lips, and rear arch under compression.
• TPMS: Plan for sensor transfer or compatible replacements. Relearn the system after mounting.
• Spacers: Only if necessary, with hub-centric designs and extended studs. Recalculate offset and bearing load.
• Tire load index and speed rating: Meet or exceed factory requirements.
• Torque: Use the Acura service manual value. Re-torque after 50–100 miles.

Known OEM fitment on this page

These values are provided for this model year page. They may vary by trim. If something looks off, confirm with your door placard and OEM documentation, then use the calculator.

Note: Rim and tire diameters above do not match. Many vehicles in this segment shipped with either 17 or 18 inch packages by trim. Verify your baseline before comparing alternates.

Next actions

Checklist

• Read the driver door placard. Record OE tire size and load index.
• Call an Acura parts counter with your VIN. Ask for OE wheel size and offset for your exact trim.
• Enter those confirmed values in Installed on (your vehicle) in the calculator.
• Compare donor wheels and Custom wheel size settings. Target similar inner clearance and controlled outer poke.
• Keep overall tire diameter close to stock. Many aim for within about 3 percent.
• Plan hardware: correct lug nuts or bolts, hub-centric rings if needed, and TPMS solution.
• Test-fit one corner. Check caliper, strut, fender, and lock-to-lock clearance under load.
• Install with a calibrated torque wrench. Re-torque after heat cycles.

Calculator tips

• Width and offset interact. If you add 0.5 inch width, you may need a few mm of offset change to keep inner clearance.
• Use a straightedge against the fender to gauge poke during test-fit.
• If the calculator shows inner clearance under a few millimeters, assume contact risk when tires flex.

Helpful tools

• Wheel torque wrench 1/2 inch drive
• Digital caliper for measuring hub bore and hardware
• Hub-centric rings 64.1 mm ID
• M14x1.5 lug nuts, match seat to your wheel

Support

If your verified specs differ from the values above, trust the placard and OEM data for your VIN. Then use the calculator to model changes before you buy. This keeps your 2012 Acura TL safe, predictable, and free from rubbing or hardware interference.
