Kia Forte Tire Pressure (Recommended PSI)
TL;DR
33 PSI front/rear is standard across most Forte trims and years, but the GT trim with 18-inch wheels needs 35 PSI - check your driver-door placard to be sure.
Where the real number lives
Every Kia Forte has a factory-printed placard on the inside edge of the driver's door (open the door and look at the door jamb, not the door itself). It lists the exact cold tire pressure for the tire size your specific car left the factory with, along with the original tire size and load rating. The owner's manual repeats the same figures. That placard - not a website - is the authoritative source, because Kia specifies pressure per trim and wheel size, not one number for the whole model.
What we verified across sources
Cross-checking tire-pressure reference sites and forum reports, the 2014-2018 Forte sedan (LX, S, EX with 15, 16 or 17-inch wheels) consistently shows 33 PSI front and rear. The 2019-2021 Forte carries the same 33 PSI baseline for FE, LXS, EX and GT-Line trims, but the sport-tuned GT trim, which rides on 225/40R18 tires, is documented at a higher 35 PSI front and rear. For 2022 and newer model years, LX and S trims on their stock tire sizes still check out at 33 PSI, but we could not corroborate a reliable figure for the GT and GT-Line tire sizes in this range across multiple sources, so we are not stating a number for those - read it off your placard.
Why the GT trim differs
The GT's lower-profile 18-inch tires carry the same vehicle weight over a smaller air volume, so Kia raises the recommended pressure to keep the sidewall properly supported and preserve handling response. This is a normal, deliberate design difference, not an error.
| Generation / years | Trim or tire size | Front (PSI) | Rear (PSI) |
|---|---|---|---|
| 2014-2018 sedan | LX (195/65R15), S (205/55R16), EX (215/45R17) | 33 | 33 |
| 2019-2021 | FE, LXS, EX, GT-Line (15-17 inch wheels) | 33 | 33 |
| 2019-2021 | GT (225/40R18) | 35 | 35 |
| 2022-2024 | LX, S (stock tire sizes) | 33 | 33 |
| 2022-2024 | GT / GT-Line (18-inch wheels) | see placard | see placard |
How to check it yourself
- Open the driver's door and read the white or silver sticker on the door jamb - it lists front and rear PSI for your exact original tire size.
- The owner's manual has an identical tire-pressure table, usually in the towing or tire-and-wheel section.
- If you fitted aftermarket wheels or a different tire size than stock, the placard figure no longer applies exactly - use the tire's max-pressure sidewall marking as an upper limit and consult a tire shop for the right setting.

Frequently asked questions
Is 33 PSI correct for every Kia Forte?
It is correct for the large majority of Forte trims and years we could verify (2014-2021 non-GT models), but the 2019-2021 GT trim with 18-inch wheels is documented at 35 PSI, and later GT/GT-Line tire sizes were not reliably confirmed - check your own door-jamb placard rather than assuming one figure fits every Forte.
Why does my Forte GT need higher pressure than my friend's Forte LX?
The GT trim uses lower-profile 225/40R18 tires instead of the smaller-diameter, taller-sidewall tires on LX, S, FE and EX trims. Kia raises the recommended pressure to 35 PSI on the GT to keep that shorter sidewall properly supported under the car's weight.
Where exactly is the placard located?
Open the driver's door fully and look at the vertical edge of the door frame (the jamb), not the door itself. You will see a white or silver sticker listing tire size, front PSI, rear PSI, and spare tire pressure if applicable.
Should I use the pressure printed on the tire's sidewall instead?
No. The number molded into the tire sidewall is the tire's maximum cold pressure rating, not Kia's recommended operating pressure. Always use the door-jamb placard or owner's manual figure for daily driving, and only treat the sidewall number as an upper safety limit.
