A 3 psi miss on one front corner of this F8 Spider shows up as a wander before the TPMS lamp bothers you. Target 34 psi (2.31 bar) cold. Under-inflation cooks the shoulders of a F8 Spider; over-inflation wears the centre rib and bangs every cat’s eye.
Ferrari F8 Spider placard versus sidewall
If the Ferrari sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.
Estimated pressure by tyre size (235/35R19 and others)
If your Ferrari F8 Spider no longer wears the OEM diameter, start at the row nearest 235/35R19 or 275/30R19 and confirm with the tyre maker’s load table.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 235/35R19 | 36 | — | 2.48 | — | 248 | — | Front 19-inch |
| 275/30R19 | 36 | — | 2.48 | — | 248 | — | Rear 19-inch |
| 245/40R18 | 35 | — | 2.41 | — | 241 | — | Square-ish sport |
| 275/35R18 | 36 | — | 2.48 | — | 248 | — | Wide rear |
| 255/35R18 | 35 | — | 2.41 | — | 241 | — | Rear stagger 18-inch |

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 | 37 psi / 2.55 bar |
Steering feel on the F8 Spider lives on this axle. Do not drop front pressure to “soften” a plus-size 245/40R18; you will roll the sidewall in a roundabout.
How to set the F8 Spider
- Park the Ferrari F8 Spider for at least three hours (cold tyres).
- Use a calibrated gauge, not the only meter on a forecourt hose.
- Set the placard for that axle — about 32-35 psi / 2.2-2.4 bar front and 32-35 psi / 2.2-2.4 bar rear on this catalogue row.
- Recheck all four. A 2 psi miss on a rear-wheel drive F8 Spider is enough to feel a pull.
- Refit valve caps and reset TPMS if the handbook asks for a relearn.

Temperature drift
Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this F8 Spider.
| 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 F8 Spider 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 F8 Spider 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 F8 Spider
Front versus rear on the Ferrari F8 Spider?
This row is 32-35 F / 32-35 R. Even when they match, a laden rear can justify a higher number if the sticker prints one.
What is that in bar and kPa for the F8 Spider?
Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.
What tyre pressure should a Ferrari F8 Spider use?
Catalogue reference is 32-35 psi front and 32-35 psi rear (2.2-2.4 / 2.2-2.4 bar), cold. Confirm on the door-pillar placard.
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.
What PSI if I plus-size toward 245/40R18?
Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 235/35R19, 275/30R19 and 245/40R18 as a planning band.
