The BAIC Beijing X55 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. Size estimates on this page include 225/65R17, 215/70R16 and 245/55R19 — interpolated from the catalogue midpoint, not a second factory sticker.

Spare and inflator kit

A matching full-size spare on the BAIC Beijing X55 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.

BAIC Beijing X55 placard versus sidewall

The tyre-information placard on a BAIC Beijing X55 sits on the driver’s door pillar (sometimes the fuel-filler flap). Catalogue figures here are a general band: 32-35 / 32-35 psi.

Temperature and a cold gauge

Roughly 1 psi per 5–6 °C. The table uses 34 psi as a 20 °C baseline for this Beijing X55.

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

Estimated pressure by tyre size (225/65R17 and others)

If your BAIC Beijing X55 no longer wears the OEM diameter, start at the row nearest 225/65R17 or 215/70R16 and confirm with the tyre maker’s load table.

How to set the Beijing X55

Park the BAIC Beijing X55 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 Beijing X55 is enough to feel a pull.
Refit valve caps and reset TPMS if the handbook asks for a relearn.

PSI, bar and kPa

1 bar ≈ 14.5 psi; 1 psi ≈ 6.89 kPa. Mid-points on the Beijing X55: 34 psi = 2.31 bar = 231 kPa.

PSI	Bar	kPa
30	2.07	207

33	2.28	228
33.5	2.31	231

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	36 psi / 2.48 bar

BAIC notes

No special BAIC exception: the Beijing X55 uses the door-pillar placard. Size estimates on this page only help if you have left the original load index behind.

If the BAIC sticker and this page disagree, the sticker wins.

Questions about this Beijing X55

Front versus rear on the BAIC Beijing X55?

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 Beijing X55?

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

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.

When does TPMS warn on a BAIC Beijing X55?

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 Beijing X55?

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