Fiat Mobi Tire Pressure (Recommended PSI)
TL;DR
Fiat Mobi trims were fitted with different tire sizes (commonly ranging from around 165/70R13 up to 175/65R14 depending on trim and model year), and the manufacturer sets pressure per tire size and load - always confirm the figure on your own door-jamb placard rather than relying on a single quoted PSI.
Why there is no single number for the Fiat Mobi
The Fiat Mobi (sold mainly in Brazil and other Latin American markets since 2016, with a facelift around 2021) was offered in multiple trims - Like, Easy, Drive, Trekking and others - each of which could be fitted with a different tire size. Automakers set a specific cold tire pressure for each tire size and load configuration, so a pressure that is correct for one trim can be wrong for another.
What we verified versus what we could not
During research for this page we were not able to independently confirm, from a credible photographed placard or an official Fiat manual excerpt, a single PSI figure that reliably applies to every Mobi generation, trim and tire size. Rather than repeat an unverified number (a mistake a prior version of this page made by publishing one 30 PSI figure as universal), we are telling you directly where to find the correct figure for your specific car.
Where to find your car's real number
- Driver's door jamb placard: open the driver's door and look at the sticker on the door frame or pillar - this lists the exact front and rear cold PSI for your specific trim and tire size as built.
- Owner's manual: the printed or digital manual that came with the car has a tire-pressure table broken out by tire size and load.
- Tire sidewall: the sidewall shows the tire's maximum pressure rating, which is not the same as the recommended everyday pressure - use the placard figure, not the sidewall maximum.
General guidance by configuration
As a general rule across small Fiat city cars in this class, front and rear pressures are often set within a couple of PSI of each other, and a full-load or long-trip setting (with more passengers or luggage) is usually a few PSI higher than the normal city-driving setting. Confirm both figures on your placard since Mobi trims vary in tire size.
| Generation / years | Trim or tire size | Front (PSI) | Rear (PSI) |
|---|---|---|---|
| Mobi, 2016-2020 (1st gen) | Like / Easy - smaller wheel option | See door placard | See door placard |
| Mobi, 2016-2020 (1st gen) | Trekking / Drive - larger wheel option | See door placard | See door placard |
| Mobi, 2021-2024 (facelift) | Like / Trekking | See door placard | See door placard |
| Mobi, 2021-2024 (facelift) | Full-load / long-trip setting (any trim) | See door placard (higher than normal) | See door placard (higher than normal) |
We chose to leave these cells qualitative rather than fill in a guessed PSI, because sources we reviewed did not agree on (or did not document) a specific figure per trim with enough confidence to publish as fact.
Summary
| Market | Brazil / Latin America (primary market) |
|---|---|
| Body style | Hatchback (city car) |
| Production years | 2016-2024, with a facelift around 2021 |
| Trims | Like, Easy, Drive, Trekking (varies by year and market) |
| Tire sizes | Vary by trim, roughly 165/70R13 to 175/65R14 |
| Authoritative source | Driver-door jamb placard and owner's manual |
| Universal PSI figure | Not confirmed - trim-dependent, check your placard |

Frequently asked questions
What is the correct tire pressure for my Fiat Mobi?
It depends on your exact trim and tire size, which is why Fiat prints it on a sticker inside the driver's door jamb rather than in a single number for the whole model. Open that door and read the front and rear cold PSI values listed there - that is the figure built specifically for your car.
Can I just use the pressure printed on the tire sidewall?
No. The number on the tire sidewall is the tire's maximum cold inflation pressure, which is a safety ceiling set by the tire manufacturer, not Fiat's recommended everyday driving pressure. Always use the door-jamb placard or owner's manual figure instead.
Does the pressure change if I load the car with passengers or luggage?
Yes, many door placards list two pressure settings, a normal-load value and a higher full-load or long-trip value. Check your placard for both figures, since carrying more weight generally calls for a few PSI more than everyday city driving.
Why don't you list one PSI number for all Fiat Mobi trims?
Because the Mobi was sold with more than one tire size across its trims and years, and a pressure correct for one tire size can be incorrect for another. We could not verify a single figure that safely applies to every configuration, so we point you to the placard on your specific vehicle instead of publishing a guess.
