Treat this page as a map of the C4 SpaceTourer band. The legal setpoint is the printed door-pillar label for your VIN. Under-inflation cooks the shoulders of a C4 SpaceTourer; over-inflation wears the centre rib and bangs every cat’s eye.

How to set the C4 SpaceTourer

Park the Citroen C4 SpaceTourer 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 front-wheel drive C4 SpaceTourer is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

Citroen C4 SpaceTourer placard versus sidewall

The tyre-information placard on a Citroen C4 SpaceTourer 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 (215/55R16 and others)

If your Citroen C4 SpaceTourer no longer wears the OEM diameter, start at the row nearest 215/55R16 or 245/40R18 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
215/55R16	34	35	2.34	2.41	234	241	Slightly wider 16-inch
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-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
205/60R16	34	34	2.34	2.34	234	234	Taller 16-inch
195/65R15	34	34	2.34	2.34	234	234	Very common compact
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM

Pressure against load

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

Temperature drift

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this C4 SpaceTourer.

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

Citroen notes

No special Citroen exception: the C4 SpaceTourer 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 Citroen C4 SpaceTourer 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 C4 SpaceTourer than nitrogen upsells.

Questions about this C4 SpaceTourer

What is that in bar and kPa for the C4 SpaceTourer?

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

When does TPMS warn on a Citroen C4 SpaceTourer?

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 C4 SpaceTourer?

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

What tyre pressure should a Citroen C4 SpaceTourer 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.

Is the sidewall number correct on a Citroen C4 SpaceTourer?

No. Sidewall PSI is a maximum. The C4 SpaceTourer placard is the operating target, near 32-35/32-35 psi.
