Lamborghini Aventador 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

European and UK handbooks usually quote bar. The Lamborghini Aventador catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target.

Lamborghini Aventador placard versus sidewall

The tyre-information placard on a Lamborghini Aventador sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.

Estimated pressure by tyre size (255/35R18 and others)

255/35R18 is the first planning size here. 245/40R18 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
255/35R18	35	36	2.41	2.48	241	248	Rear stagger 18-inch
235/35R19	36	36	2.48	2.48	248	248	Front 19-inch
245/40R18	35	36	2.41	2.48	241	248	Square-ish sport
275/35R18	36	37	2.48	2.55	248	255	Wide rear
225/40R18	35	35	2.41	2.41	241	241	Front 18-inch
255/40R17	35	36	2.41	2.48	241	248	Rear stagger 17-inch
225/45R17	34	35	2.34	2.41	234	241	Front sport size
275/30R19	36	37	2.48	2.55	248	255	Rear 19-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 Aventador

Park the Lamborghini Aventador 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 Aventador 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 Aventador.

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

Lamborghini notes

No special Lamborghini exception: the Aventador 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 Lamborghini Aventador 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 Lamborghini sticker and this page disagree, the sticker wins.

Questions about this Aventador

When does TPMS warn on a Lamborghini Aventador?

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

What is that in bar and kPa for the Aventador?

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

What tyre pressure should a Lamborghini Aventador 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.

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 255/35R18, 235/35R19 and 245/40R18 as a planning band.

How often should I check a Aventador?

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