2011 Acura TSX Wheel Interchange

OEM wheel/tire sizes and fitment specs for the 2011 Acura TSX.

2011 Acura TSX Wheel Fitment Guide

1) Misconception

Any 5x114.3 wheel should fit a 2011 Acura TSX without issues.

2) Why it seems true

A lot of Honda and Acura models share the 5x114.3 bolt pattern, and many stores group them together. On paper, that makes cross-fitment feel straightforward. If you add that offsets can look close across trims, it is easy to assume things will work.

3) What is true

Fitment is a system. Bolt pattern is only one piece. You also need the correct center bore, thread size, offset, width, diameter, and a tire diameter that keeps clearances and gearing sensible.

For the 2011 Acura TSX, here is the verified baseline we have:

Bolt pattern (studs x PCD)5x114.3
Center bore (mm)64.1
Thread sizeM12 x 1.5
OEM wheel example18 x 8.0, ET 50, backspacing 5.97 in
OEM tire example225/50R17

Quick recap: those wheel and tire examples reflect common factory setups, but trims and option packages can differ. If your door-jamb label or owner’s manual shows something different, trust that and use the on-page calculator to compare.

Think of it as a mental model with three checks:

  • Mounting: 5x114.3 pattern, M12x1.5 threads, and a wheel bore that is 64.1 mm or larger. If larger, hub-centric rings bring it down to 64.1 mm.
  • Geometry: width and offset set inner clearance to the strut and outer poke to the fender. A practical rule of thumb is to keep offset changes modest so inner and outer movements stay manageable.
  • Tire diameter: aim to keep overall tire diameter close to stock so your speedometer and gearing feel right. Many people target within about 2 to 3 percent.

How to use the Wheel Interchange calculator on this page:

  • Set “Installed on (your vehicle)” to 2011 Acura TSX.
  • If you have a candidate wheel, pick it under “Wheels from (donor vehicle)” or enter its size under “Custom wheel size.”
  • Adjust “Custom tire size” to see the new overall diameter. The tool updates the tire diameter as you change rim diameter.
  • Watch the inner and outer clearance changes and the tire diameter difference. That shows you where rubbing or poke could happen.

4) Implications

Getting the pattern right means the wheel goes on the studs. Getting the center bore right means the wheel centers properly on the hub and runs smooth. If your aftermarket wheel has a larger bore than 64.1 mm, a set of hub-centric rings that steps down to 64.1 mm helps reduce vibration. If the offset is pushed too low with a wider wheel, the outer edge can contact the fender liner. If offset goes too high, the inner barrel can get close to the strut or spring perch.

Lug hardware matters. The threads are M12x1.5, but lug seat style depends on the wheel. Match the lug nut seat to the wheel seat (for example, conical vs ball) and confirm the shank or taper depth the wheel needs. If your TSX uses a TPMS system, you may need to transfer sensors or program replacements when changing wheels. For torque specs, use the value in your owner’s manual or service information.

5) Quick tests

  • Pattern and bore check: confirm 5x114.3 and that the wheel bore is 64.1 mm or larger. If larger, plan for 64.1 mm hub-centric rings.
  • Thread and lug nuts: verify M12x1.5 threads and the correct seat style for the wheel. Hand-thread lugs to ensure smooth engagement.
  • Calculator pass: enter the wheel and tire in the calculator. Ensure inner clearance and outer poke changes look reasonable and tire diameter stays close to stock.
  • Dry fit: mount one wheel without the tire or with the tire deflated. Spin by hand and check strut, brake caliper, and fender clearance.
  • Road check: after installation, take a short, low-speed drive, then re-check torque after a short interval. Re-verify after a few drives.

Helpful tools

Bottom line

Bolt pattern gets the wheel on the car. Offset, width, bore, and tire diameter make it drive the way you expect. Use the calculator to compare your options against the 2011 Acura TSX baseline above, confirm details from your door sticker or OEM sources, and you will land on a setup that fits and feels right.
