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
Most of the engineering value in a forged wheel over a cast one shows up in rotational mass, not outright strength — both can meet the same load rating, but the forged piece gets there lighter. On a sedan platform tuned for everyday balance, that weight saving is felt directly in steering response and ride quality.
The Chevrolet Impala Sedan runs a 5x115 bolt pattern, 70.3mm center bore, and a 16x6.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 18x8.5J ET40, which tucks the tire under the fender lip on a stock-height Chevrolet Impala Sedan. Our Maximum Aggressive reference is 19x9.0J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Chevrolet Impala Sedan OE Wheel Specs
The 2001 Chevrolet Impala Sedan (Sedan) uses a 5x115 bolt pattern with a 70.3mm center bore. Factory wheels are 16x6.5J F/R.
Why the factory spec works for most owners:
- Balances ride comfort with everyday fuel efficiency
- A widely used size in this segment, so tire and wheel availability stays strong
- Keeps unsprung weight low for stable, predictable handling
- Maintains clearance for the factory brake calipers and suspension components
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Chevrolet Impala Sedan (2001) we drill the 5x115 pattern and cut the centre bore to 70.3mm 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 Impala Sedan? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
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) | 16x6.5J | ET51 | 5.76 in (146 mm) | — | — |
| Flush | 18x8.5J | ET40 | 6.32 in (161 mm) | +14 mm | +36 mm |
| Maximum | 19x9J | ET35 | 6.38 in (162 mm) | +16 mm | +48 mm |
Vehicles With the Same Hub as the Chevrolet Impala Sedan (5x115, 70.3 mm Bore)
In our database, 135 other vehicle entries from 9 makes use exactly the same 5x115 bolt pattern and 70.3 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.
5x115 is used by 3.2% of the vehicle pages in our English fitment guide (209 of 6,503); 65.1% of those also use a 70.3 mm center bore.
Hub-Centric Rings for a 70.3 mm Center Bore
A wheel with a center bore larger than 70.3 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 70.5 mm | 70.5 → 70.3 mm |
| 71.6 mm | 71.6 → 70.3 mm |
| 72.6 mm | 72.6 → 70.3 mm |
| 73.1 mm | 73.1 → 70.3 mm |
ANKUSI forged wheels are bored to exactly 70.3 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Chevrolet Impala Sedan use?
The 2001 Chevrolet Impala Sedan uses a 5x115 bolt pattern.
How many lug bolts does the Chevrolet Impala Sedan use?
The Chevrolet Impala Sedan uses a 5-lug bolt pattern (5x115), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Chevrolet Impala Sedan?
The Chevrolet Impala Sedan's center bore is 70.3mm. 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 Impala Sedan?
Factory wheels on the Chevrolet Impala Sedan are 16x6.5J F/R.
What is the biggest wheel size I can fit on my Chevrolet Impala Sedan without rubbing?
The most aggressive fitment we recommend without fender work is 19x9.0J 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 Impala Sedan?
For a flush look with minimal to no rubbing, we recommend 18x8.5J at ET40 offset as a starting point on a stock or mildly lowered Chevrolet Impala Sedan.
Do I need wheel spacers for my Chevrolet Impala Sedan?
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 Impala Sedan?
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 6.32" 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 Impala Sedan?
The Chevrolet Impala Sedan 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: Vehicles built before the 2008 model year were not federally required to carry factory TPMS in the US, though many manufacturers adopted it earlier; verify whether your specific build has TPMS before ordering sensor-compatible wheels.
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.
