Chevrolet Onix Tire Pressure (Recommended PSI)
TL;DR
The current-generation Latin American Onix hatch calls for 32/32 PSI cold unladen and 32F/38R loaded, plus 60 PSI for the compact spare. Earlier (first-generation, 2012-2019) cars and higher trims riding on 16-inch low-profile tires were not consistently corroborated, so check those directly on the placard.
Brazil and Latin America are the primary market for this car
The Onix hatchback reviewed here is the model built and sold by GM in Brazil for the Latin American market (it is not sold in North America). Two generations exist: the original Onix (roughly 2012-2019) and the second generation, sold as Onix or Onix Plus/hatch on the GEM platform (2019 onward, still current for 2025-2026). Pressure specifications can differ between these generations and even between trims of the same generation, so treat any single number with caution.
Where to find the real number for your car
The only fully authoritative source is the placard on your own vehicle: look at the driver-side door jamb sticker (some Onix units carry it inside the fuel-filler flap instead), or your owner's manual. Tire sidewall markings show the tire's maximum pressure rating, not the recommended one - do not use that number. If you tow or carry a full load, check the loaded-condition figure on the same placard.
What we could verify
Across several independent placard-reference sources covering Onix model years from about 2019 through 2025, the recurring, agreed figures for the standard tire fitment (commonly 185/65 R15) are 32 PSI front and 32 PSI rear for normal cold, unladen driving, and 32 PSI front and 38 PSI rear when the vehicle is carrying a full complement of occupants and luggage. The compact temporary spare is consistently listed at 60 PSI.
What we could not verify (treat with caution)
We could not independently corroborate a specific placard figure for the first-generation Onix (2012-2019), nor for trims fitted with the low-profile 205/55 R16 tire option offered on some higher trims (for example LTZ or Premier variants). Sources disagree or are silent on whether those configurations use the same 32/32 PSI baseline or a different value. Do not assume they match the second-generation figure - read your own placard.
| Generation / years | Trim or tire size | Front (PSI) | Rear (PSI) |
|---|---|---|---|
| 2nd gen Onix / Onix Plus hatch (2019-2025) | Standard fitment, e.g. 185/65 R15 - normal load | 32 | 32 |
| 2nd gen Onix / Onix Plus hatch (2019-2025) | Standard fitment - full load (all seats plus luggage) | 32 | 38 |
| 2nd gen Onix / Onix Plus hatch (2019-2025) | Compact temporary spare tire | 60 | 60 |
| 2nd gen Onix / Onix Plus hatch (2019-2025) | Low-profile 205/55 R16 (higher trims, e.g. LTZ/Premier) | Not corroborated - check placard | Not corroborated - check placard |
| 1st gen Onix (2012-2019) | All trims / tire sizes | Not corroborated - check placard | Not corroborated - check placard |
Practical checking tips
- Check pressure cold, meaning the car has been parked for at least three hours or driven less than 1.6 km (1 mile).
- Recheck every couple of weeks and always before a long trip, since pressure drops roughly 1 PSI for every 5-6 C drop in temperature.
- If your placard lists a value that differs from anything on this page, the placard always wins - it is calibrated to your exact vehicle weight and tire fitment.
Summary
| Market covered | Brazil / Latin America (Onix is not sold in North America) |
|---|---|
| 2nd gen (2019-2025) standard tire, unladen | 32 PSI front / 32 PSI rear |

| Compact spare tire | 60 PSI |
| 1st gen (2012-2019) figure | Not corroborated - check your placard |
| 16-inch low-profile trims (e.g. LTZ/Premier) | Not corroborated - check your placard |
| Authoritative source | Driver door-jamb placard or owner's manual, checked cold |

Frequently asked questions
What is the correct cold tire pressure for a Chevrolet Onix hatchback?
For the current (second-generation, 2019-2025) Latin American Onix hatch with its standard tire fitment, placard-referenced sources agree on 32 PSI front and 32 PSI rear unladen, and 32 PSI front / 38 PSI rear fully loaded. Older (2012-2019) cars and trims with the optional 205/55 R16 low-profile tire were not consistently corroborated, so read your own door-jamb placard to be sure.
Where is the tire pressure placard located on the Onix?
It is normally on the driver-side door jamb sticker; on some Onix units it is instead printed on the inside of the fuel-filler flap. The owner's manual repeats the same figures. Use whichever the manufacturer put on your specific car, not a number copied from the internet.
Can I just use the pressure printed on the tire sidewall?
No. The number molded into the tire sidewall is the tire's maximum cold inflation pressure rating, not Chevrolet's recommended pressure for your Onix. Always use the vehicle placard or owner's manual figure instead.
Does tire pressure change between trims like LT, LTZ, or Premier?
It can, because different trims sometimes use different wheel and tire sizes (for example 185/65 R15 versus a lower-profile 205/55 R16 on some higher trims), and a different tire size can carry a different recommended pressure. We could not fully corroborate the exact figure for the low-profile option, so check the placard on that specific trim rather than assuming it matches the standard-tire figure.
