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
Hot hatches and performance compacts are built around quick direction changes, so rotational mass at the wheel has an outsized effect on how the car actually feels to drive. Forging trims that mass while holding the same strength margin as the factory wheel, which is exactly the trade-off this kind of platform rewards.
The Fiat 500 Riva runs a 4x98 bolt pattern, 58.1mm center bore, and a 16x6.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 17x7.0J ET32, which tucks the tire under the fender lip on a stock-height Fiat 500 Riva. Our Maximum Aggressive reference is 17x7.5J ET28 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Fiat 500 Riva OE Wheel Specs
The 2017 Fiat 500 Riva (Hatchback) uses a 4x98 bolt pattern with a 58.1mm center bore. Factory wheels are 16x6.5J F/R.
Why the factory spec works for most owners:
- Keeps the factory ride quality and noise levels intact
- A common fitment for this class, so replacement tires are easy to source
- Preserves clearance around the OE brakes and suspension geometry
- Delivers predictable, easy-to-live-with handling for daily use
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Fiat 500 Riva (2017) we drill the 4x98 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.

Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 16x6.5J ET35 → ~5.13″ backspacing
- Flush: 17x7.0J ET32 → ~5.26″ backspacing
- Max: 17x7.5J ET28 → ~5.35″ 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 Fiat spec, or want a wheel built to a custom offset for your Fiat 500 Riva? 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 Fiat 500 Riva (4x98, 58.1 mm Bore)
In our database, 53 other vehicle entries from 9 makes use exactly the same 4x98 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.
4x98 is used by 1.1% of the vehicle pages in our English fitment guide (74 of 6,503); 73.0% 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 Fiat 500 Riva use?
The 2017 Fiat 500 Riva uses a 4x98 bolt pattern.
How many lug bolts does the Fiat 500 Riva use?
The Fiat 500 Riva uses a 4-lug bolt pattern (4x98), so you need a 4-lug forged wheel to bolt straight on.
What is the center bore size on the Fiat 500 Riva?
The Fiat 500 Riva'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 Fiat 500 Riva?
Factory wheels on the Fiat 500 Riva are 16x6.5J F/R.
What is the biggest wheel size I can fit on my Fiat 500 Riva without rubbing?
The most aggressive fitment we recommend without fender work is 17x7.5J at ET28 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 Fiat 500 Riva?
For a flush look with minimal to no rubbing, we recommend 17x7.0J at ET32 offset as a starting point on a stock or mildly lowered Fiat 500 Riva.
Do I need wheel spacers for my Fiat 500 Riva?
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 Fiat 500 Riva?
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 5.26" 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 Fiat 500 Riva?
The Fiat 500 Riva 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.
