PSI is the Imperial reading most UK motorists still see on garage hoses. For the Ferrari GTC4 Lusso the catalogue row is 32-35 psi front and 32-35 psi rear. Size estimates on this page include 245/40R18, 225/50R17 and 225/45R17 — interpolated from the catalogue midpoint, not a second factory sticker.

Estimated pressure by tyre size (245/40R18 and others)

If your Ferrari GTC4 Lusso no longer wears the OEM diameter, start at the row nearest 245/40R18 or 225/50R17 and confirm with the tyre maker’s load table.

How to set the GTC4 Lusso

Park the Ferrari GTC4 Lusso 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 GTC4 Lusso is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

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	37 psi / 2.55 bar

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this GTC4 Lusso.

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 GTC4 Lusso 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 GTC4 Lusso 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.

A cheap gauge and a monthly habit will do more for this GTC4 Lusso than nitrogen upsells.

Questions about this GTC4 Lusso

Front versus rear on the Ferrari GTC4 Lusso?

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.

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.

When does TPMS warn on a Ferrari GTC4 Lusso?

Direct TPMS typically flags about 25% below placard — near 25 psi on this row. Fill to the sticker, not to the lamp.

How often should I check a GTC4 Lusso?

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 GTC4 Lusso?

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