Ferrari F50 bar chart (2.2-2.4 / 2.2-2.4)

Drivetrain: rear-wheel drive
Body: passenger car
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

bar

2.31 / 2.31

32-35 / 32-35 psi · 231 / 231 kPa

32-35 psi F · 32-35 psi R · 2.2-2.4 / 2.2-2.4 bar · 231/231 kPa

2.3 bar is not 23 psi. On this F50 2.2-2.4 bar converts to about 32-35 psi. Use the table, not a guess. Under-inflation cooks the shoulders of a F50; over-inflation wears the centre rib and bangs every cat’s eye.

Bar, PSI and kPa

Bar-led conversions around the Ferrari F50. 2.2-2.4 bar is not “32-35 divided by ten”.

Ferrari F50 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 (245/40R18 and others)

Planning cold pressures for sizes often seen on a passenger car. This F50 sample opens with 245/40R18, then 215/55R16 and 225/40R18.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-inch
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
205/60R16	34	34	2.34	2.34	234	234	Taller 16-inch
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-inch
185/65R15	33	33	2.28	2.28	228	228	Small / older car
225/45R17	35	35	2.41	2.41	241	241	Sport 17-inch

Load notes

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	34 psi / 2.34 bar	35 psi / 2.41 bar
Motorway + luggage	35 psi / 2.41 bar	38 psi / 2.62 bar

How to set the F50

Park the Ferrari F50 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 F50 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 F50.

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 F50 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 F50 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 F50

How often should I check a F50?

Monthly, before a long trip, and after a 10 °C weather swing. Include a full-size spare.

What PSI if I plus-size toward 225/40R18?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/40R18, 215/55R16 and 225/40R18 as a planning band.

What is that in bar and kPa for the F50?

Mid-points are about 2.31 bar (231 kPa) front and 2.31 bar (231 kPa) rear.

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.

Front versus rear on the Ferrari F50?

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.
