Treat this page as a map of the 488 band. The legal setpoint is the printed door-pillar label for your VIN. A 10 °C overnight drop takes roughly 1 psi (0.07 bar) off a closed Ferrari tyre.
How to set the 488
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep 488 numbers in your head.
- Add air in short bursts toward 34 psi (2.31 bar) front and 34 psi rear.
- If one corner is 4 psi down, hunt for a nail before you blame the weather.
- Log date, ambient temperature and the four readings.
Ferrari 488 placard versus sidewall

Estimated pressure by tyre size (235/35R19 and others)
235/35R19 is the first planning size here. 225/45R17 is usually the plus-size or LT step. Keep load index at or above original equipment.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 235/35R19 | 36 | 36 | 2.48 | 2.48 | 248 | 248 | Front 19-inch |

PSI, bar and kPa

Pressure against load
Load moves the rear of a passenger car first. If the factory placard already has a “laden” column, use that instead of these sketches.
| Condition | Front (est.) | Rear (est.) |
|---|---|---|
| Driver only | 34 psi / 2.34 bar | 34 psi / 2.34 bar |
| Full occupancy | 35 psi / 2.41 bar | 36 psi / 2.48 bar |
| Motorway + luggage | 36 psi / 2.48 bar | 38 psi / 2.62 bar |
Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this 488.
| Ambient | Gauge (front mid) | Bar | kPa | Note |
|---|---|---|---|---|
| −5 °C (hard frost) | 31 psi | 2.14 bar | 214 kPa | Gauge reads low; do not overfill once warm |
| 0 °C | 32 psi | 2.21 bar | 221 kPa | Gauge reads low; do not overfill once warm |
| 8 °C (UK winter morning) | 33 psi | 2.28 bar | 228 kPa | Gauge reads low; do not overfill once warm |
| 20 °C (set cold here) | 34 psi | 2.34 bar | 234 kPa | Baseline |
| 30 °C | 36 psi | 2.48 bar | 248 kPa | Do not bleed a hot tyre |
| 38 °C (heatwave tarmac) | 37 psi | 2.55 bar | 255 kPa | Do not bleed a hot tyre |
Ferrari notes
No special Ferrari exception: the 488 uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.
Spare and inflator kit
A matching full-size spare on the Ferrari 488 usually follows the higher axle (often the rear, near 32-35 psi). A space-saver is commonly 60 psi / 4.1 bar — read that tyre’s own sidewall. An inflator kit is not a spare; check the sealant date.
If the Ferrari sticker and this page disagree, the sticker wins.

Questions about this 488
What PSI if I plus-size toward 225/45R17?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 235/35R19, 255/35R18 and 225/45R17 as a planning band.
How often should I check a 488?
Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.
What is that in bar and kPa for the 488?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
Is the sidewall number correct on a Ferrari 488?
No. Sidewall PSI is a maximum. The 488 placard is the operating target, near 32-35/32-35 psi.
Should I bleed pressure after a motorway run?
No. Heat raises the gauge. Set cold only. Bleeding a hot tyre leaves it low the next morning.
