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 Saab 93 ships from the factory on a 5x110 bolt pattern with a 65.1mm center bore and a 15x4J ET40 wheel. Our flush reference for the Saab 93 is 15x4.5J ET30.; our maximum aggressive reference is 15x5J ET25. — beyond that, expect clearance issues against the fender liner without further modification.
Saab 93 OE Wheel Specs
The Saab 93 ships from the factory on 5x110 bolt pattern wheels with a 65.1mm center bore. The stock wheel size is 15x4J ET40, 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 Saab 93 (1959) we drill the 5x110 pattern and cut the centre bore to 65.1mm 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.
Converting these ET figures to backspacing? Use the wheel offset and backspacing calculator.

Offset & Backspacing Reference
Backspacing is calculated as: wheel width (in) / 2 + offset (mm) / 25.4 + 0.5.
- OE 15x4J ET40: backspacing ≈ 4.07"
- Flush 15x4.5J ET30: backspacing ≈ 3.93"
- Max 15x5J ET25: backspacing ≈ 3.98"

Vehicles With the Same Hub as the Saab 93 (5x110, 65.1 mm Bore)
In our database, 139 other vehicle entries from 19 makes use exactly the same 5x110 bolt pattern and 65.1 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.
5x110 is used by 2.2% of the vehicle pages in our English fitment guide (145 of 6,503); 96.6% of those also use a 65.1 mm center bore.
Hub-Centric Rings for a 65.1 mm Center Bore
A wheel with a center bore larger than 65.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 66.1 mm | 66.1 → 65.1 mm |
| 66.6 mm | 66.6 → 65.1 mm |
| 67.1 mm | 67.1 → 65.1 mm |
| 70.1 mm | 70.1 → 65.1 mm |
| 73.1 mm | 73.1 → 65.1 mm |
ANKUSI forged wheels are bored to exactly 65.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Saab 93 use?
The 1959 Saab 93 uses a 5x110 bolt pattern.
How many lug bolts does the Saab 93 use?
The Saab 93 uses a 5-lug bolt pattern (5x110), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Saab 93?
The Saab 93's center bore is 65.1mm. 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 Saab 93?
For a flush look with minimal to no rubbing, we recommend 15x4.5J at ET30 offset as a starting point on a stock or mildly lowered Saab 93.
Do I need wheel spacers for my Saab 93?
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 Saab 93?
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 3.93" 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 Saab 93?
The Saab 93 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.
