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
On a compact performance platform, every pound of rotational mass fights the car's natural agility. A forged wheel keeps strength at the factory-rated level while cutting that rotational weight, which is where the driving-feel improvement actually comes from.
The Alfa Romeo 147 TI runs a 5x98 bolt pattern, 58.1mm center bore, and a 17x7.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 18x8.0J ET35, which tucks the tire under the fender lip on a stock-height Alfa Romeo 147 TI. Our Maximum Aggressive reference is 18x8.5J ET32 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Alfa Romeo 147 TI OE Wheel Specs
The 2003 Alfa Romeo 147 TI (Hatchback) uses a 5x98 bolt pattern with a 58.1mm center bore. Factory wheels are 17x7.0J 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 Alfa Romeo 147 TI (2003) we drill the 5x98 pattern and cut the centre bore to 58.1mm 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 (flange allowance):
- OE: 17x7.0J ET40.5 → ~5.59″ backspacing
- Flush: 18x8.0J ET35 → ~5.88″ backspacing
- Max: 18x8.5J ET32 → ~6.01″ backspacing
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 Alfa Romeo spec, or want a wheel built to a custom offset for your Alfa Romeo 147 TI? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Vehicles With the Same Hub as the Alfa Romeo 147 TI (5x98, 58.1 mm Bore)
In our database, 30 other vehicle entries from 6 makes use exactly the same 5x98 bolt pattern and 58.1 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.
5x98 is used by 0.5% of the vehicle pages in our English fitment guide (32 of 6,503); 96.9% of those also use a 58.1 mm center bore.
Hub-Centric Rings for a 58.1 mm Center Bore
A wheel with a center bore larger than 58.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 60.1 mm | 60.1 → 58.1 mm |
| 63.4 mm | 63.4 → 58.1 mm |
| 64.1 mm | 64.1 → 58.1 mm |
| 65.1 mm | 65.1 → 58.1 mm |
| 73.1 mm | 73.1 → 58.1 mm |
ANKUSI forged wheels are bored to exactly 58.1 mm for this vehicle, so no ring is needed.
Frequently Asked Questions
What bolt pattern (PCD) does the Alfa Romeo 147 TI use?
The 2003 Alfa Romeo 147 TI uses a 5x98 bolt pattern.
How many lug bolts does the Alfa Romeo 147 TI use?
The Alfa Romeo 147 TI uses a 5-lug bolt pattern (5x98), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Alfa Romeo 147 TI?
The Alfa Romeo 147 TI's center bore is 58.1mm. 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 Alfa Romeo 147 TI?
Factory wheels on the Alfa Romeo 147 TI are 17x7.0J F/R.
What is the biggest wheel size I can fit on my Alfa Romeo 147 TI without rubbing?
The most aggressive fitment we recommend without fender work is 18x8.5J at ET32 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 Alfa Romeo 147 TI?
For a flush look with minimal to no rubbing, we recommend 18x8.0J at ET35 offset as a starting point on a stock or mildly lowered Alfa Romeo 147 TI.
Do I need wheel spacers for my Alfa Romeo 147 TI?
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 Alfa Romeo 147 TI?
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 5.88" 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 Alfa Romeo 147 TI?
The Alfa Romeo 147 TI 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.
