Treat this page as a map of the Beijing X55 band. The legal setpoint is the printed door-pillar label for your VIN. Under-inflation cooks the shoulders of a Beijing X55; over-inflation wears the centre rib and bangs every cat’s eye.

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.

Estimated pressure by tyre size (245/60R18 and others)

245/60R18 is the first planning size here. 235/60R18 is usually the plus-size or LT step. Keep load index at or above original equipment.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
245/60R18	36	37	2.48	2.55	248	255	Heavier CUV
225/65R17	35	35	2.41	2.41	241	241	Very common 17-inch
235/60R18	36	36	2.48	2.48	248	248	Plus-size 18-inch
225/60R18	35	35	2.41	2.41	241	241	Highway CUV
235/65R17	35	36	2.41	2.48	241	248	Mid-size SUV
245/55R19	36	36	2.48	2.48	248	248	Low-profile 19-inch
255/50R20	37	37	2.55	2.55	255	255	20-inch plus-size

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	35 psi / 2.41 bar	36 psi / 2.48 bar
Motorway + luggage	36 psi / 2.48 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 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

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.

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.

Keep the BAIC Beijing X55 on the printed band; use 245/60R18 and 235/60R18 only as a map for non-OEM wheels.

Questions about this Beijing X55

What tyre pressure should a BAIC Beijing X55 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.

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 PSI if I plus-size toward 235/60R18?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 245/60R18, 225/65R17 and 235/60R18 as a planning band.

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.

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.
