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.
ANKUSI Engineering Expert Advice
Convertibles lose some of the structural rigidity a fixed roof provides, which means the suspension and wheels end up doing more of the work to keep the chassis composed. A forged wheel keeps unsprung mass down without sacrificing the strength margin the factory built in — useful on a platform that's already managing extra flex.
The Lexus LC 500 Convertible ships from the factory on a 5x120 bolt pattern with a 60.1mm center bore and a F 20x8.5J ET25 / R 20x9.5J ET25 wheel. Our flush reference for the Lexus LC 500 Convertible is F 21x9.5J ET20 / R 21x10.5J ET20.; our maximum aggressive reference is F 22x10J ET15 / R 22x11J ET15. — beyond that, expect clearance issues against the fender liner without further modification.
Lexus LC 500 Convertible OE Wheel Specs
The Lexus LC 500 Convertible ships from the factory on 5x120 bolt pattern wheels with a 60.1mm center bore. The stock wheel size is F 20x8.5J ET25 / R 20x9.5J ET25, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:
- Balances ride comfort with steering response and highway efficiency.
- Wide tire and wheel availability at the factory diameter keeps replacement costs low.
- Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
- Guaranteed clearance against brake calipers and suspension components.
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Lexus LC 500 Convertible (2021) we drill the 5x120 pattern and cut the centre bore to 60.1mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

The figures on this page are part of our open wheel fitment dataset — 10,093 vehicles, free to download, CC BY 4.0.
Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 20x8.5J | ET25 | 5.73 in (146 mm) | — | — |
| Flush | 21x9.5J | ET20 | 6.04 in (153 mm) | +8 mm | +18 mm |
| Maximum | 22x10J | ET15 | 6.09 in (155 mm) | +9 mm | +29 mm |
Vehicles With the Same Hub as the Lexus LC 500 Convertible (5x120, 60.1 mm Bore)
In our database, 28 other vehicle entries from 3 makes use exactly the same 5x120 bolt pattern and 60.1 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
5x120 is used by 10.3% of the vehicle pages in our English fitment guide (670 of 6,503); 4.3% of those also use a 60.1 mm center bore.
Hub-Centric Rings for a 60.1 mm Center Bore
A wheel with a center bore larger than 60.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 63.4 mm | 63.4 → 60.1 mm |
| 64.1 mm | 64.1 → 60.1 mm |
| 65.1 mm | 65.1 → 60.1 mm |
| 66.1 mm | 66.1 → 60.1 mm |
| 73.1 mm | 73.1 → 60.1 mm |
ANKUSI forged wheels are bored to exactly 60.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Lexus LC 500 Convertible use?
The 2021 Lexus LC 500 Convertible uses a 5x120 bolt pattern.
How many lug bolts does the Lexus LC 500 Convertible use?
The Lexus LC 500 Convertible uses a 5-lug bolt pattern (5x120), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Lexus LC 500 Convertible?
The Lexus LC 500 Convertible's center bore is 60.1mm. 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.
What does a flush wheel fitment look like on the Lexus LC 500 Convertible?
For a flush look with minimal to no rubbing, we recommend F 21x9.5J ET20 / R 21x10.5J ET20 as a starting point on a stock or mildly lowered Lexus LC 500 Convertible.
Do I need wheel spacers for my Lexus LC 500 Convertible?
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.
How do I calculate wheel backspacing for my Lexus LC 500 Convertible?
Backspacing (in inches) = wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance). For example, the flush spec above works out to roughly 6.04" backspacing up front and 6.54" in the rear.
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 Lexus LC 500 Convertible?
Yes — the Lexus LC 500 Convertible's factory and our recommended flush/max fitments already use staggered sizing (different width front and rear), and ANKUSI can forge matching staggered sets to your target offsets.
