BAIC Beijing X55 rear tyres: 32-35 psi / 2.2-2.4 bar

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

psi rear

2.31 bar · 231 kPa at the rear axle

32-35 psi F · 32-35 psi R · 2.2-2.4 / 2.2-2.4 bar · 231/231 kPa

The rear of a SUV / crossover takes passengers, luggage and, on vans, payload. Catalogue rear pressure on the BAIC Beijing X55 is 32-35 psi / 2.2-2.4 bar. Size estimates on this page include 235/65R17, 245/55R19 and 215/70R16 — interpolated from the catalogue midpoint, not a second factory sticker.

BAIC Beijing X55 placard versus sidewall

Sidewall PSI is a carcass maximum. Recommended operating pressure for this Beijing X55 is the pillar sticker, near 34/34 psi.

Estimated pressure by tyre size (235/65R17 and others)

If your BAIC Beijing X55 no longer wears the OEM diameter, start at the row nearest 235/65R17 or 245/55R19 and confirm with the tyre maker’s load table.

Tyre size	Front PSI	Rear PSI	Front bar	Rear bar	Front kPa	Rear kPa	Note
235/65R17	—	36	—	2.48	—	248	Mid-size SUV
245/55R19	—	36	—	2.48	—	248	Low-profile 19-inch
215/70R16	—	34	—	2.34	—	234	Compact crossover
245/60R18	—	37	—	2.55	—	255	Heavier CUV
225/60R18	—	35	—	2.41	—	241	Highway CUV
225/65R17	—	35	—	2.41	—	241	Very common 17-inch
255/50R20	—	37	—	2.55	—	255	20-inch plus-size
235/60R18	—	36	—	2.48	—	248	Plus-size 18-inch

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	38 psi / 2.62 bar

A family SUV / crossover with a boot full of luggage should use the laden rear figure if Ford, VW or Mercedes printed one. Otherwise the modest steps in the load table are only a sketch for this Beijing X55.

How to set the Beijing X55

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep Beijing X55 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.

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.

A cheap gauge and a monthly habit will do more for this Beijing X55 than nitrogen upsells.

Questions about this Beijing X55

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.

Is the sidewall number correct on a BAIC Beijing X55?

No. Sidewall PSI is a maximum. The Beijing X55 placard is the operating target, near 32-35/32-35 psi.

What PSI if I plus-size toward 215/70R16?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 235/65R17, 245/55R19 and 215/70R16 as a planning band.

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.
