BAIC Senova X55 tyre pressure in bar

2.3 bar is not 23 psi. On this Senova X55 2.2-2.4 bar converts to about 32-35 psi. Use the table, not a guess. Size estimates on this page include 215/70R16, 245/60R18 and 225/65R17 — interpolated from the catalogue midpoint, not a second factory sticker.

Estimated pressure by tyre size (215/70R16 and others)

215/70R16 is the first planning size here. 225/65R17 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
215/70R16	34	34	2.34	2.34	234	234	Compact crossover
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
255/50R20	37	37	2.55	2.55	255	255	20-inch plus-size
235/60R18	36	36	2.48	2.48	248	248	Plus-size 18-inch
235/65R17	35	36	2.41	2.48	241	248	Mid-size SUV
225/60R18	35	35	2.41	2.41	241	241	Highway CUV
245/55R19	36	36	2.48	2.48	248	248	Low-profile 19-inch

Load notes

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

How to set the Senova X55

Measure before the school run, not after the M25.
Write LF / RF / RR / RL. Do not keep Senova 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.
Log date, ambient temperature and the four readings.

Temperature drift

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

Questions about this Senova X55

How often should I check a Senova X55?

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

Front versus rear on the BAIC Senova 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.

What PSI if I plus-size toward 225/65R17?

Keep load index at or above OEM. Low-profile sizes usually stay at or slightly above the placard. Use 215/70R16, 245/60R18 and 225/65R17 as a planning band.

What is that in bar and kPa for the Senova X55?

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

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.
