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 Chevrolet Blazer runs a 6x120 bolt pattern, 66.9mm center bore, and a 20x8.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 22x9.0J ET40, which tucks the tire under the fender lip on a stock-height Chevrolet Blazer. Our Maximum Aggressive reference is 22x9.5J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Chevrolet Blazer OE Wheel Specs
The 2023 Chevrolet Blazer (SUV) uses a 6x120 bolt pattern with a 66.9mm center bore. Factory wheels are 20x8.0J F/R.
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 Chevrolet Blazer (2023) we drill the 6x120 pattern and cut the centre bore to 66.9mm 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.

A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Chevrolet spec, or want a wheel built to a custom offset for your Chevrolet Blazer? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Chevrolet Blazer: Specs by Model Year
| Year | Bolt pattern | Center bore | Factory wheel |
|---|---|---|---|
| 1999 | 5x120.65 | 70.3 mm | 15x7J |
| 2000 | 5x120.65 | 70.3 mm | 15x7J ET50 |
| 2001 | 5x120.65 | 70.3 mm | 15x7J |
| 2002 | 5x120.65 | 70.3 mm | 15x7J ET50 |
| 2019 | 6x120 | 66.9 mm | 20x8J ET50 |
| 2023 | 6x120 | 66.9 mm | 20x8J ET50 |
Check the model year before ordering: the specs change — bolt pattern 5x120.65 → 6x120 from 2019; center bore 70.3 mm → 66.9 mm from 2019.
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) | 20x8J | ET50 | 6.47 in (164 mm) | — | — |
| Flush | 22x9J | ET40 | 6.57 in (167 mm) | +3 mm | +23 mm |
| Maximum | 22x9.5J | ET35 | 6.63 in (168 mm) | +4 mm | +34 mm |
Vehicles With the Same Hub as the Chevrolet Blazer (6x120, 66.9 mm Bore)
In our database, 32 other vehicle entries from 5 makes use exactly the same 6x120 bolt pattern and 66.9 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.
6x120 is used by 0.5% of the vehicle pages in our English fitment guide (34 of 6,503); 97.1% of those also use a 66.9 mm center bore.
Hub-Centric Rings for a 66.9 mm Center Bore
A wheel with a center bore larger than 66.9 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 67.1 mm | 67.1 → 66.9 mm |
| 70.1 mm | 70.1 → 66.9 mm |
| 70.5 mm | 70.5 → 66.9 mm |
| 71.6 mm | 71.6 → 66.9 mm |
| 73.1 mm | 73.1 → 66.9 mm |
ANKUSI forged wheels are bored to exactly 66.9 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Chevrolet Blazer use?
The 2023 Chevrolet Blazer uses a 6x120 bolt pattern.
How many lug bolts does the Chevrolet Blazer use?
The Chevrolet Blazer uses a 6-lug bolt pattern (6x120), so you need a 6-lug forged wheel to bolt straight on.
What is the center bore size on the Chevrolet Blazer?
The Chevrolet Blazer's center bore is 66.9mm. 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 Chevrolet Blazer?
Factory wheels on the Chevrolet Blazer are 20x8.0J F/R.
What is the biggest wheel size I can fit on my Chevrolet Blazer without rubbing?
The most aggressive fitment we recommend without fender work is 22x9.5J at ET35 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 Chevrolet Blazer?
For a flush look with minimal to no rubbing, we recommend 22x9.0J at ET40 offset as a starting point on a stock or mildly lowered Chevrolet Blazer.
Do I need wheel spacers for my Chevrolet Blazer?
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 Chevrolet Blazer?
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 6.57" 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 Chevrolet Blazer?
The Chevrolet Blazer 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: 136 Nm (100 ft-lb). Covers most Chevrolet passenger cars and crossovers on M12 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.
