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
Because an SUV's center of gravity is already higher than a sedan's, anything added at the corners — including wheel weight — has an outsized effect on handling balance. A forged wheel lets us hit the visual stance owners want without adding the rotational mass a cast wheel of the same strength would carry.
The Toyota bZ4X runs a 5x114.3 bolt pattern, 60.1mm center bore, and a 18x7.5J at ET40, front and rear, wheel from the factory. Our Flush Fitment reference is 20x8.5J, which tucks the tire under the fender lip on a stock-height Toyota bZ4X. Our Maximum Aggressive reference is 20x9.0J at ET30 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Toyota bZ4X OE Wheel Specs
The 2026 Toyota bZ4X (Electric SUV) uses a 5x114.3 bolt pattern with a 60.1mm center bore. Factory wheels are 18x7.5J at ET40 offset, front and rear.
Why the factory spec works for most owners:
- Supports the vehicle's curb weight and load capacity
- Preserves ground clearance for everyday and light off-road use
- Balances ride comfort with cargo and passenger stability
- Maintains clearance for the factory suspension travel and brake package
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Toyota bZ4X (2026) we drill the 5x114.3 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.

Toyota bZ4X: Specs by Model Year
| Year | Bolt pattern | Center bore | Factory wheel |
|---|---|---|---|
| 2023 | 5x114.3 | 60.1 mm | 18x7.5J ET40 |
| 2026 | 5x114.3 | 60.1 mm | 18x7.5J ET40 |
Bolt pattern and center bore stay the same across all 2 model years in our database (2023–2026).
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) | 18x7.5J | ET40 | 5.82 in (148 mm) | — | — |
| Maximum | 20x9J | ET30 | 6.18 in (157 mm) | +9 mm | +29 mm |
Vehicles With the Same Hub as the Toyota bZ4X (5x114.3, 60.1 mm Bore)
In our database, 216 other vehicle entries from 19 makes use exactly the same 5x114.3 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.
5x114.3 is used by 20.0% of the vehicle pages in our English fitment guide (1,300 of 6,503); 16.8% 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 Toyota bZ4X use?
The 2026 Toyota bZ4X uses a 5x114.3 bolt pattern.
How many lug bolts does the Toyota bZ4X use?
The Toyota bZ4X uses a 5-lug bolt pattern (5x114.3), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Toyota bZ4X?
The Toyota bZ4X'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 size are the factory (stock) wheels on the Toyota bZ4X?
Factory wheels on the Toyota bZ4X are 18x7.5J at ET40 offset, front and rear.
What is the biggest wheel size I can fit on my Toyota bZ4X without rubbing?
The most aggressive fitment we recommend without fender work is 20x9.0J at ET30 offset. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.
What does a flush wheel fitment look like on the Toyota bZ4X?
For a flush look with minimal to no rubbing, we recommend 20x8.5J at ET35 offset as a starting point on a stock or mildly lowered Toyota bZ4X.
Do I need wheel spacers for my Toyota bZ4X?
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 Toyota bZ4X?
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 6.13" of backspacing.
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 Toyota bZ4X?
The Toyota bZ4X 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.
Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M12x1.5, conical-seat lug nut.
Factory Torque Spec: 103-110 Nm (76-81 ft-lb). Range covers most Toyota passenger cars, crossovers, and light trucks on M12x1.5 studs.
TPMS: TPMS (Tire Pressure Monitoring System) has been federally mandated on all new light vehicles sold in the US since the 2008 model year. If your wheels use OE-style sensors, have them transferred or cloned to the new wheels at installation.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
