2013 Acura TSX Wheel Interchange

OEM wheel/tire sizes and fitment specs for the 2013 Acura TSX.

tl;dr

The 2013 Acura TSX uses 5x114.3 bolt pattern, 64.1 mm center bore, and M12x1.5 studs. Provided data shows an 18x8 ET50 wheel and a 225/50R17 tire. That implies trim variation. Confirm your exact OEM size on the door placard and with the calculator on this page. Keep swaps hub-centric, offset close to stock, and verify clearances.

Recommendation

Start from stock geometry, then make small, tested changes. Keep the bolt pattern and center bore exact. Match the lug seat type to your wheels. Use the on-page calculator to compare a donor wheel to your TSX, and to model custom wheel and tire sizes. Aim to keep overall tire diameter close to stock and offset near the factory value for predictable handling. Use hub-centric rings if your aftermarket wheel bore is larger than 64.1 mm.

Impact

  • Offset changes alter inner clearance and fender poke.
  • Diameter and tire profile affect speedometer and ABS logic.
  • Width and offset together drive fender and strut clearance.
  • Heavier combos add unsprung mass, impacting ride and braking.
  • Tire load rating and speed rating affect safety and insurance.

Risks

  • Center bore too small will not seat. Too large needs rings to stay hub-centric.
  • Wrong lug nut seat type causes loss of clamping force.
  • Insufficient inner clearance can hit struts, knuckles, or brake lines.
  • Outer poke can cut tires on fender lips under compression.
  • Spacers reduce thread engagement if studs are short. Use hub-centric spacers only with proper hardware.
  • TPMS requirements can vary by market and trim. Confirm sensor type before swapping.

Known OEM fitment for 2013 Acura TSX

Parameter Value Notes
Bolt pattern 5x114.3 Exact match required for stud alignment.
Center bore 64.1 mm Hub-centric fit on OEM hubs.
Thread size M12 x 1.5 Match lug nuts and studs to this pitch.
Wheel size 18 x 8.0 Known data point. May vary by trim.
Offset (ET) 50 mm Keep close for geometry and bearing load.
Backspacing 5.97 in Derived from width and offset.
Tire size 225/50R17 Known data point. Confirms 17 inch trim exists.

Notes: The wheel and tire values above show both 18 inch and 17 inch OEM setups. This is consistent with trim differences. Do not assume both apply to your car. Confirm your door placard and cross-check with the calculator and OEM sources.

How to use the calculator

  • Set Installed on to 2013 Acura TSX.
  • Pick Wheels from to match a donor vehicle or wheel you are considering.
  • Use Custom wheel size to try different rim diameter, width, and offset.
  • Use Custom tire size to match section width and aspect ratio.
  • Changing rim diameter updates tire diameter in the comparison. Watch inner clearance and outer poke numbers.
  • Keep diameter change modest for speedometer accuracy and clearance. Small changes are easier to live with.

Checklist

  • Confirm your OEM size on the door jamb and in the owner’s manual.
  • Identify your current wheel markings inside the barrel for size and offset.
  • Model your target setup in the calculator. Keep offset near ET50 and verify inner clearance remains positive.
  • Match bolt pattern 5x114.3, center bore 64.1 mm, and thread M12x1.5.
  • If aftermarket wheel bore is larger, order 64.1 mm hub-centric rings. Search hub-centric rings
  • Use correct-seat lug nuts for your wheel. Search M12x1.5 lug nuts
  • Test fit a front corner first. Check caliper, strut, and liner clearance at full lock and bump.
  • Torque to the OEM spec with a calibrated wrench. Re-torque after 50 to 100 miles. Search torque wrenches
  • Get an alignment if you change width or offset.

Gotchas: Do not mix lug seat styles. Do not rely on spacers to fix poor fitment. Verify TPMS requirements before mounting tires.
