How many lug bolts does the Acura TSX use?

The Acura TSX uses a 5-lug bolt pattern (5x114.3), so you need a 5-lug forged wheel to bolt straight on.

What size are the factory (stock) wheels on the Acura TSX?

Factory wheels on the Acura TSX are 17x7.0J at ET55, front and rear (215/50R17).

Do I need wheel spacers for my Acura TSX?

No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.

What's the difference between wheel offset and backspacing?

Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.

Can I run staggered wheels (different sizes front and rear) on my Acura TSX?

The Acura TSX runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.

Q: What is the center bore size on the Acura TSX?

The Acura TSX's center bore is 64.1mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.

Acura TSX (2004-2008): 5x114.3 bolt pattern, 64.1mm center bore. 17x7.0J F/R at ET55. Aftermarket reference ranges coming soon.

How to Read Wheel Offset & Measurements

Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.

Aftermarket Fitment Data -- Coming Soon

We are still verifying real-world Flush and Maximum Aggressive reference fitments for this exact generation from owner communities, so we are not publishing offset ranges yet rather than guessing. Check back soon, or contact ANKUSI now with your target look and tire size and we will confirm a custom-offset forged wheel build for your Acura TSX directly.
