2005 Acura TL Wheel Interchange

2005 Acura TL Wheel Fitment Guide

tl;dr

Start from OEM specs, then model changes in the on-page calculator. The 2005 TL uses a 5x114.3 pattern, 64.1 mm hub bore, and M12x1.5 studs. Provided data shows an 18x8 ET45 wheel and a 235/45R17 tire. That is a mismatch by diameter, which likely varies by trim or package. Confirm your car’s factory size, then keep offsets close and overall tire diameter tight.

2005 Acura TL quick specs

Note the 18-inch wheel vs 17-inch tire conflict above. Some trims or packages differ. Check your driver-door placard and owner’s manual, then set that as “Installed on (your vehicle)” in the calculator.

Recommendation

I set up 2005 TL fitments this way in the shop:

• Use the calculator baseline with the values above.
• Verify your OEM wheel and tire size on the door placard.
• Keep new wheel offset near ET45 to preserve geometry.
• Match center bore with hub-centric rings if wheels are larger bore. Inner ring must be 64.1 mm.
• Use M12x1.5 lug nuts with the correct seat for your wheels.
• Model any diameter change. Aim for minimal overall tire diameter delta.
• Test front brake clearance and inner strut clearance before mounting tires.

Impact

• Diameter changes affect speedometer and gearing feel.
• Offset changes affect scrub radius and steering feel.
• Wider wheels can improve grip but may rub at full lock.
• Too much backspacing risks strut or knuckle contact.
• Too little backspacing can push tires past the fender.
• Unsprung weight rises with larger wheels, impacting ride.

The calculator shows inner and outer clearance shifts and tire diameter. Use it to visualize fender and suspension room before buying.

Risks and gotchas

• Spec mismatch in the provided data means you must confirm your trim’s OEM size.
• Wrong lug seat type can loosen under load. Match cone, ball, or mag seat to the wheel.
• Insufficient stud engagement is unsafe. Ensure full thread engagement with spacers.
• Non-hub-centric mounting can cause vibration. Use rings to 64.1 mm.
• TPMS considerations vary. If equipped, plan sensor transfer or relearn.
• Load rating matters. Wheels and tires must meet or exceed axle loads.

Next actions

• Confirm OEM tire and wheel size on the door placard and in the owner’s manual.
• Open the on-page calculator.
• Set “Installed on (your vehicle)” to 2005 Acura TL with your confirmed OEM size.
• Enter your candidate “Wheels from (donor vehicle)” or use “Custom wheel size”.
• Adjust rim diameter, width, and offset. Watch inner and outer clearance changes.
• Set “Custom tire size”. The tool will update total tire diameter.
• Aim to keep diameter change small and offset close to ET45.
• Plan hardware: hub-centric rings 64.1 mm ID, M12x1.5 nuts, and proper seats.
• Test fit a front corner. Check caliper, knuckle, and fender clearance at full lock and bump.
• Torque lugs to the OEM spec from Acura. Re-torque after 50–100 miles.

Checklist

• 5x114.3 bolt pattern confirmed
• 64.1 mm hub bore matched or ringed
• M12x1.5 lug nuts with correct seat
• Offset near ET45 modeled in calculator
• Overall tire diameter change minimized
• Brake and suspension clearance verified
• Load ratings and TPMS plan in place

Helpful tools and supplies

• 1/2 inch drive torque wrench
• M12x1.5 conical lug nuts
• Hub-centric rings, 64.1 mm inner

Select ring outer diameter to match your aftermarket wheel bore. Verify lug seat type with your wheel supplier.

Notes on data accuracy

We only publish what is provided. The 18-inch wheel and 17-inch tire values conflict, which suggests trim variation or an input error. Use the calculator with your verified OEM size and cross-check with Acura documentation. When in doubt, prioritize the door placard and the owner’s manual.
