Peugeot J9 bar chart (2.2-2.4 / 2.2-2.4)

Drivetrain: front-wheel drive
Body: passenger car
PSI F / R: 32-35 / 32-35
Bar F / R: 2.2-2.4 / 2.2-2.4

European and UK handbooks usually quote bar. The Peugeot J9 catalogue is 2.2-2.4 bar front and 2.2-2.4 bar rear (midpoint 2.31 / 2.31). Under-inflation cooks the shoulders of a J9; over-inflation wears the centre rib and bangs every cat’s eye.

If the Peugeot sticker is painted over, the handbook is next. This website is a map, not a replacement VIN label.

Estimated pressure by tyre size (225/50R17 and others)

Planning cold pressures for sizes often seen on a passenger car. This J9 sample opens with 225/50R17, then 225/40R18 and 205/55R16.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
225/50R17	35	35	2.41	2.41	241	241	Touring 17-inch
225/40R18	36	36	2.48	2.48	248	248	Low-profile 18-inch
205/55R16	34	34	2.34	2.34	234	234	Typical mid-compact OEM
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
185/65R15	33	33	2.28	2.28	228	228	Small / older car
245/40R18	36	36	2.48	2.48	248	248	Wide touring 18-inch
215/50R17	35	35	2.41	2.41	241	241	Plus-size 17-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	37 psi / 2.55 bar

How to set the J9

Park the Peugeot J9 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 J9 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 J9.

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

Peugeot notes

Peugeot often prints bar. A 2.4 bar 308 is about 35 psi. Do not copy a Partner van figure onto a hatchback.

Spare and inflator kit

A matching full-size spare on the Peugeot J9 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 Peugeot sticker and this page disagree, the sticker wins.

Questions about this J9

What PSI if I plus-size toward 205/55R16?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 225/50R17, 225/40R18 and 205/55R16 as a planning band.

Front versus rear on the Peugeot J9?

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.

How often should I check a J9?

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

When does TPMS warn on a Peugeot J9?

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

Is the sidewall number correct on a Peugeot J9?

No. Sidewall PSI is a maximum. The J9 placard is the operating target, near 32-35/32-35 psi.
