Porsche Cayenne: 2.2-2.4 bar / 32-35 psi

Drivetrain: all-wheel drive
Body: SUV / crossover

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

The Porsche Cayenne catalogue band is 32-35 psi front and 32-35 psi rear — 2.2-2.4 / 2.2-2.4 bar, or about 231 / 231 kPa — measured cold. TPMS typically warns near 25 psi (about 25% below target). That is already a soft tyre, not a fill target. Keep side-to-side spread inside about 2 psi so the all-wheel drive hardware is not working on a radius mismatch.

Spare and inflator kit

A matching full-size spare on the Porsche Cayenne 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.

Porsche notes

No special Porsche exception: the Cayenne uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.

How to set the Cayenne

Park the Porsche Cayenne 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 all-wheel drive Cayenne is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

Porsche Cayenne placard versus sidewall

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

Pressure against load

Load moves the rear of a SUV / crossover 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

Estimated pressure by tyre size (215/70R16 and others)

If your Porsche Cayenne no longer wears the OEM diameter, start at the row nearest 215/70R16 or 235/65R17 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/70R16	34	34	2.34	2.34	234	234	Compact crossover
235/65R17	35	36	2.41	2.48	241	248	Mid-size SUV
225/65R17	35	35	2.41	2.41	241	241	Very common 17-inch

245/55R19	36	36	2.48	2.48	248	248	Low-profile 19-inch
225/60R18	35	35	2.41	2.41	241	241	Highway CUV
255/50R20	37	37	2.55	2.55	255	255	20-inch plus-size

PSI, bar and kPa

1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Mid-points on the Cayenne: 34 psi = 2.31 bar = 231 kPa.

Temperature and a cold gauge

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

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

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

Questions about this Cayenne

Front versus rear on the Porsche Cayenne?

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 Cayenne?

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

What tyre pressure should a Porsche Cayenne 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.

How often should I check a Cayenne?

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

What PSI if I plus-size toward 225/65R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 215/70R16, 235/65R17 and 225/65R17 as a planning band.
