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 Cayenne 2.2-2.4 bar converts to about 32-35 psi. Use the table, not a guess. Under-inflation cooks the shoulders of a Cayenne; over-inflation wears the centre rib and bangs every cat’s eye. Keep side-to-side spread inside about 2 psi so the all-wheel drive hardware is not working on a radius mismatch.
Bar, PSI and kPa
Bar-led conversions around the Porsche Cayenne. 2.2-2.4 bar is not “32-35 divided by ten”.

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.
Estimated pressure by tyre size (245/55R19 and others)
Planning cold pressures for sizes often seen on a SUV / crossover. This Cayenne sample opens with 245/55R19, then 235/60R18 and 225/65R17.
| Tyre size | Front PSI | Rear PSI | Front bar | Rear bar | Front kPa | Rear kPa | Note |
|---|---|---|---|---|---|---|---|
| 245/55R19 | 36 | 36 | 2.48 | 2.48 | 248 | 248 | Low-profile 19-inch |
| 235/60R18 | 36 | 36 | 2.48 | 2.48 | 248 | 248 | Plus-size 18-inch |
| 225/65R17 | 35 | 35 | 2.41 | 2.41 | 241 | 241 | Very common 17-inch |
| 225/60R18 | 35 | 35 | 2.41 | 2.41 | 241 | 241 | Highway CUV |
| 215/70R16 | 34 | 34 | 2.34 | 2.34 | 234 | 234 | Compact crossover |
| 255/50R20 | 37 | 37 | 2.55 | 2.55 | 255 | 255 | 20-inch plus-size |
| 235/65R17 | 35 | 36 | 2.41 | 2.48 | 241 | 248 | Mid-size SUV |
| 245/60R18 | 36 | 37 | 2.48 | 2.55 | 248 | 255 | Heavier CUV |
Load notes
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 |
How to set the Cayenne
- Measure before the school run, not after the M25.
- Write LF / RF / RR / RL. Do not keep Cayenne numbers in your head.
- Add air in short bursts toward 34 psi (2.31 bar) front and 34 psi rear.
- If one corner is 4 psi down, hunt for a nail before you blame the weather.
- Log date, ambient temperature and the four readings.
Temperature drift
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 |
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.
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.
If the Porsche sticker and this page disagree, the sticker wins.

Questions about this Cayenne
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.
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 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.
Is the sidewall number correct on a Porsche Cayenne?
No. Sidewall PSI is a maximum. The Cayenne placard is the operating target, near 32-35/32-35 psi.
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.
