Fiat Cronos Bolt Pattern, Wheel & Tire Sizes
TL;DR
The Cronos uses a 4x98 mm bolt pattern (4 lug bolts, M12x1.5 thread) with a 58.1 mm centre bore across the trims and years we could verify - always confirm the exact tire size for your specific trim on the tire sidewall or door placard.
Which Cronos this covers
The Fiat Cronos is a Latin-American market sedan (Brazil and Argentina production, sold across South America) built on a single generation since its 2018 launch, with a visual and equipment facelift introduced for the 2023-2024 model years. This page treats the Brazil/LatAm-spec car as the primary subject. We did not find evidence of a bolt-pattern change between the pre-facelift and facelift cars, and several fitment references explicitly list 4x98 mm as running from 2018 to the present, but we recommend double-checking your own wheel if you are shopping for aftermarket rims.
Bolt pattern, centre bore and stud thread
Independent wheel-fitment references (including Brazilian wheel retailers and general fitment databases) consistently report a 4x98 mm bolt pattern for the Cronos, using M12x1.5 lug bolts (not studs - Fiat uses bolts that thread into the hub), with a 58.1 mm centre bore. These three figures agreed across the sources we checked, so we are confident in them for the trims sold in Brazil and neighboring markets.
Wheel and tire sizes
Factory wheel sizes vary by trim: entry trims (such as Drive) are commonly fitted with 15 inch wheels, mid trims (Precision and similar) with 16 inch wheels, and the sportier top trims (HGT/Absolute) with 17 inch wheels. Retailer fitment charts we reviewed listed rim widths around 6.0J for the 15 and 16 inch wheels and 6.5J for the 17 inch wheel. We could not fully corroborate the exact tire section width/profile (for example whether the base tire is a 175, 185 or 195 section) for every trim from independent sources, so treat the tire sizes below as a general guide and always read the actual size off your tire sidewall or the placard on the driver's door jamb, which is the manufacturer's figure for your specific car.
Why this matters for aftermarket wheels
If you are buying aftermarket wheels, matching the 4x98 mm pattern and 58.1 mm centre bore (or using a hub-centric ring if the aftermarket wheel has a larger bore) is essential for the wheel to seat correctly and for the lug bolts to thread in safely. Do not rely on a bolt pattern quoted for a different Fiat model (such as the Argo or Mobi) without checking, since patterns are not always shared across the range.
Where to find the authoritative number for your car
Because trims and model years can differ, the figure that overrides everything on this page is the one on your own vehicle: check the driver's door placard (tire pressure and size sticker), the owner's manual, and the markings on your current wheels and tires (the tire sidewall shows size, and the wheel back shows bolt count and sometimes PCD).
| Generation / years | Bolt pattern | Centre bore | Stud thread | Stock wheel sizes | Common tire sizes |
|---|---|---|---|---|---|
| Cronos, 2018-2022 (pre-facelift) | 4x98 mm | 58.1 mm | M12x1.5 (lug bolts) | 15-17 in depending on trim | Varies by trim - confirm on sidewall |
| Cronos, 2023-present (facelift) | 4x98 mm (no change found) | 58.1 mm | M12x1.5 (lug bolts) | 15-17 in depending on trim | Varies by trim - confirm on sidewall |

Frequently asked questions
What bolt pattern does the Fiat Cronos use?
Multiple independent wheel-fitment references agree the Cronos (Brazil/LatAm market, 2018-present) uses a 4x98 mm bolt pattern with M12x1.5 lug bolts. We found no evidence this changed with the 2023-2024 facelift, but confirm on your own wheel before ordering aftermarket rims.
What is the centre bore of the Fiat Cronos?
Fitment references list a 58.1 mm centre bore for the Cronos. If you fit an aftermarket wheel with a larger bore, use a hub-centric ring to keep the wheel centered on the hub rather than resting on the lug bolts alone.
What size wheels come on the Fiat Cronos from the factory?
Factory wheel size depends on trim: base trims typically run 15 inch wheels, mid trims 16 inch, and higher sport trims (HGT/Absolute) 17 inch. Check your door placard or the wheel itself to confirm what your specific car has.
Does the Fiat Cronos use lug bolts or lug studs?
It uses lug bolts (the bolt threads directly into the wheel hub, M12x1.5), which is common on Fiat/Stellantis South American models, rather than studs with separate lug nuts.
